  • You Ask, I Answer: What Grade Level for Website Readability?

    You Ask, I Answer: What Grade Level for Website Readability?

    Tiff asks, “At what reading level should website copy be written? Is it the same as print?”

    The answer to this question depends on two things: your audience, and what readability score you’re using. There are 5 major readability scores:
    – Flesch-Kincaid grade level – words/sentences – syllables/words
    – Gunning-Fog index – words/sentences – complex words (3 syl)/words
    – SMOG index – complex words / number of sentences (minimum 30 sentences)
    – Automated Readability index – characters/words + words/sentences
    – Coleman-Liau index – character-based, letters / 100 words – sentences / 100 words

    Most tools use FK, but FK isn’t always the best choice – often, for marketing copy, SMOG is a better choice, or Gunning-Fog if your software supports it.

    The secret is this: measure the media diet of your audience and determine it from that grade level. Watch the video for an explanation of how.

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode tip asks, at what reading level should website copy be written? Is it the same as print? So the answer to this question is dependent on two things.

    The first is, what readability tool are using, what measure are you using? And second, what audience reading level do you have? What does your audience read at? So there’s a bunch of different ways to tackle this.

    Let’s talk about the algorithms.

    First, there’s five major algorithms for readability.

    There is the flesh Kincaid grade level algorithm, which is essentially the number of words divided by the number of sentences minus the number of syllables in the words divided by the number of words.

    All these algorithms by the way are done in software.

    You don’t have to implement any of them yourself, but you do need to know which algorithm your software is using a lot of the time.

    software will not necessarily tell you up front, you may have to ask the developers, but you’re going to get different answers depending on the on the algorithms been used.

    And different algorithms are appropriate for different use cases.

    Second is the Gunning-Fog index.

    This is a words divided by sentences minus complex words, which are three syllables or more divided by the number of words.

    Gunning-Fog was intended for things like health care, and the same for the following measure.

    Because you’re looking for it, trying to reduce the number of complex words, to make something more readable.

    The next one is called smog.

    And this is a simple measure of gobbledygook, which is a simplification gutting fog.

    It is simply the number of complex words divided by the number of sentences with a minimum of 30 sentences.

    And there’s actually a bunch of tuning parameters that go into each of these but again, the software you’re using, done that I’m just giving you the basic idea behind each of these algorithms.

    The fourth is the automated, readable to index, this is the number of characters divided by the number of words, plus the number of words divided by the number of sentences.

    And the last one is the Coleman-Liau index, which is character based.

    And that is the number of letters divided by the number of letters per 100.

    Words, minus the number of sentences are 100 words Coleman-Liau was invented for machines, essentially machines, reading scanning of these different measures, the one that folks tend to use a lot in when they’re developing tools is the flesh Kincaid grade level score.

    But it’s not necessarily the best choice.

    And the reason for that is that if you’re trying to reduce word, complexity of reading, it’s those big polysyllabic words, those overly complicated words, long syllable words that can sometimes mess up reading level and with that, Gunning-Fog or smog are probably the two indexes that are the better choices for reducing the complexity of something that you’re trying to read.

    smog is used a lot in healthcare Gunning-Fog was used.

    It was built for the US Navy, to, to reduce the complexity of technical manuals to the field manuals that soldiers are given is to make it easier for them to use.

    So both of those indexes are good for marketing content because good marketers like to be fancy, right and use big words and stuff to make their their copy sound more sophisticated, especially b2b marketers.

    We all love our flexible, scalable turnkey inter integrated solutions, etc.

    As opposed to software that does the thing and that those complex polysyllabic words are the ones that make readability more difficult so for marketers Gunning-Fog and smug are probably the the two algorithms to use.

    So you’ll want to check which what algorithm your software uses.

    Now, how do you determine your audience? There’s a couple different ways you can do this.

    Number one, if you have access to like your customer service inbox, or reviews written by your audience and things like that, you can copy and paste a whole bunch of them together and get an overall average readability level of the way that your audience writes.

    The other way is to use social media monitoring software.

    If you have a list of known customers, for example, like a Twitter list, you would put that into social media monitoring software, and then extract out from that data, the publications that your audience shares the most.

    Go on to the Ito’s publications take a sample random sample like 10 articles from those publications.

    Put that through your readability software and that will tell you like your audience is consuming and sharing content at say a sixth grade level or an eighth grade level.

    That way you can dial in on exactly where your audience is based on the stuff that they’re already sharing.

    If your audience isn’t active on social, then you’re gonna have to, you know, solicit content from other places.

    A good way of doing that, again, is asking people in on intake forms or on customer service calls or in surveys.

    You know, hey, what publications do you read? What newspapers or news sources do you read? What books do you read, that will help you again, dial in and calibrate on where your audience’s reading level is based on their media diet.

    Once you’ve got that, then you can start making content that’s appropriate to the grade level that people are at.

    The other thing that you’re going to want to do is you’re going to want to measure carefully.

    readability is is a metric it is not necessarily an outcome.

    So one of the things to do is to look at you run a, an attribution analysis at at the page level, across your web copy and look for the pages that convert the most.

    And then measure the readability scores, and then do just a simple regression analysis to see Is there any relationship between readability and conversion capability? There may be there may not be if you run that analysis, and there’s no correlation, then is readability a problem? It wouldn’t hurt to dial things into where your audience is most comfortable.

    But if you find that say, your top converting page is written at a substantially different grade level than the like your least converting page and there’s no logical relationship between the two then don’t invest a huge amount of time in changing the readability the rest of your site.

    The thing to do is would be to set up a a have actual experiment like a clinical trial, take 10 pages of no take 20 pages, 10 of them have a gonna be ones you’re gonna modify the reading level 10 of them mean, you’re not going to modify the reading level, they should all be roughly about the same level of conversion power within your analysis.

    And then once you’ve made the changes, observe and see if the conversion power changes over time.

    Because you have you made those readability changes, don’t change anything else.

    Just make sure it’s, it’s, you know, 10 and 10.

    each one’s a control one’s the experiment and see if readability changes make a difference.

    If they make a difference.

    Great, then, you know, even after a couple of weeks, right, that readability is actually important to audience.

    If nothing happens, you probably don’t need to spend a whole lot more time on it, but I would run that test.

    So your steps are First, identify the media diet, choose the algorithm that you’re going to use, then assess your site, look for that relationship and if there is relationship of some kind, then set up a test and and test and approve 10 pages and leave 10 pages alone and see how they interact.

    readability is is part of natural language processing.

    There’s a lot of fun things you can do with it but that’s for another time.

  • You Ask, I Answer: Can AI Write as Well as a Human?

    You Ask, I Answer: Can AI Write as Well as a Human?

    Deborah asks, “Can AI write as well as a human?”

    The answer depends on what the human is writing. If it’s complex, original works like novels, the answer is no. If it’s marketing swill, the answer is yes. If we examine some common readability metrics – which are decent proxies for content quality – we see that marketing-centric content tends to be junk writing.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode Deborah asks Can AI right as well as a human? Well? The answer is it depends on what the human is writing language generation models, natural language generation of models, like open a eyes GPT series of models, or the T five Transformers from Google can write reasonably well, you know, in a very general sense, but the more specific the task, the better they get, the more guidance you give them and more guardrails you put on the better they get something like a complex original work like say a novel answer’s no machines cannot write as well as human not without an extraordinary amount of training and resources.

    To the point where it’s not cost efficient, you’d be better off hiring novelist to write a novel, then you would be to try and train a machine.

    Even if the machine could generate, you know, 1000 pulp novels.

    The amount of editing time and QA that would have to go into it would effectively negate any gains you got out of it.

    Now, if it’s marketing swill, the answer is yes.

    And the reason for that is, a lot of what we write in marketing is junk, right? It’s not very good quality content.

    It’s actually it’s pretty appallingly bad content.

    And it’s easy for machines to replicate crap.

    Think about a bell curve, right? On one end, you have low quality content on another and you have high quality content in the middle is a bunch of mediocre stuff.

    As machines evolve, they go from, they can replicate total garbage, right, because that’s pretty easy.

    And then they start to iterate and get slightly better and now they’re kind of at the meeting.

    Yoker phase, right? They can write mediocre marketing as well, can they write good quality copy or great quality copy, not really not without, again, a lot of training to the point where it is not cost efficient to do that unless you’re a company that is dedicated to doing that.

    But if you or the look at the metrics, in fact, let’s do this.

    Let’s bring this up here.

    What we’re looking at here is four sets of readability scores for a lot of marketing copy.

    So this is articles, blog posts, press releases, essentially it is content marketing stuff, right and not very good.

    And this is 130,000 of these that we have stored in the TrustInsights.ai database.

    I have four quadrants, we have the jargon score, which is the smog score, simple measure of gobbledygook.

    We have the flesh Kincaid readability index.

    We have the Coleman layout index.

    And the flesh Kincaid grade level.

    What you notice here is that there is a definite skew towards the right side for three graphs and sort of a bell curve in the middle.

    So let’s walk through these briefly.

    The jargon score, lower is better, right? So you want that content be easier to read than harder to read.

    And in this case, there’s a very definite kurtosis or lean towards the harder to read side means that our content is full of jargon, and a lot of it on readability, the readability score, 100 is great.

    Zero is bad.

    And we see a bell curve there in the middle, you know, 5055 60 is where most continents so it’s, again, it’s mediocre content, right? There’s very, very little on the far side here of the readability index, it says, Yeah, you got great content, very thin.

    On Coleman Liao.

    Again, this is similar to grade level, you can see there’s a tremendous amount of very difficult to Read content on the far right hand side and then I’ll hold opposite field.

    And then on the flesh Kincaid grade level, we see that marketing content is around nine ninth to 11th grade content because of the jargon because of the amount of stuff that we put in our copy that is difficult to read.

    That is extensively polysyllabic, which means that we use real big words.

    You know, think about the, the list of corporate buzzwords that we love to use.

    And you can see that reflected here in this data that this data very clearly shows we love our our fancy, complicated language.

    When you have language like that, when you have, you know, buzzword bingo, you have templates, an awful lot of things like you know, basic blog posts are very templated when you have press releases, announcements, They all follow a copy that is so formulaic, that is very easy for machines to replicate and probably do a better job than the majority of humans.

    Because when these natural language generation models are trained on language, they’re not trained on just one specific domain.

    They’re trained on as much language as possible.

    The most recent version of GPG three was trained on something like 170 5 billion parameters, which is a massive, massive, massive amount of texts, basically, the bulk of the readable text in English online.

    That means that when these machines go to generate language, they will naturally use more vocabulary a little bit more.

    lexical diversity is the technical term than a human would because in a lot of cases, humans will just copy and paste the last thing they did.

    I used to work at a public relations agency and I would literally watch you know, Junior associates Just copy and paste from one press release to the next change the name of the company in the name of the CEO.

    But effectively, they all say the same thing.

    You know, the chief executive says, you know, we’re so excited or proud or pleased or release our new version, whatever, whatever, whatever.

    And we’re flexible, scalable, industry leading agile, you know, can a machine replicate that hundred percent, hundred percent a machine can replicate that and do better than, than the humans do? So can AI right as well as the human? It depends on the context.

    But for sure.

    machines can now right at, I would say the mediocre level, right? The they could they’ve got bad down.

    They’ve got a mat down.

    They’ve got they’re getting mediocre down.

    Now.

    As each model improves, as the technology improves, they will eventually get down good.

    Good writing.

    Right.

    And for those companies that have the strongest infrastructure and the greatest level of resources, some will get great writing down.

    What does that mean for you as a as a marketing practitioner, it means that you’ve got to be improving your skills.

    If you are on the bad side of writing, you probably need to stop writing for marketing and look at a different profession.

    Because the machines can already crank out swell better than you can.

    If you’re in the mat mediocre, you better uplevel those skills, take some courses, do some writing workshops, do anything that whatever you can do, that will improve your skills and get them to good write.

    If you’re a good writer, you’ll keep working to become a great writer.

    But whatever you do, you cannot stay static.

    You cannot just rest on your laurels at wherever you are this continuum.

    Because the machines are advancing faster than then we are collectively.

    Will there come a day when you push a button and the machine spits out a novel probably We are already seeing a prototype examples of this with GPT three open AI model.

    Is it good yet? No.

    But it definitely shows what is possible.

    What is what is theoretically possible.

    And what is possible today is easily achievable in five to 10 years, maybe less depending on how fast compute power goes up.

    So that’s the answer to this question.

    AI can write as well as humans who are bad at their job.

    AI can write as well as humans who were mediocre at their job.

    And AI will eventually write as well as humans who are good at their job.

    So your job as a human is to become great at writing so that you stay ahead of the machines.

  • You Ask, I Answer: Why do Recommendation Engines Fail?

    You Ask, I Answer: Why do Recommendation Engines Fail?

    Oz asks, “Why is some consumer AI so bad? Instagram senses that I like bright-colored clothes. Then it shows me ads for bright-colored clothes that are also cheap crap that I’d never buy. What is the perspective of the companies?
    – It works great for most people.
    – We just need to get this right for 5% of people and that covers the cost.
    – We know it generally sucks but it’s better than nothing.”

    A lot of it is based on recommendation engines which have two issues – first, superficial data, and two, they’re a generation or two behind what’s current because of the enormous computational costs. Something like Netflix is going to use something like an LSTM because while it may not be as accurate, it scales much better than a gigantic, many-layer neural network that wouldn’t be able to update in real-time after you watched something.

    A third part has to do with compensation model and objective optimization. What is the objective these ad systems are tuned for?

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode oz asks, Why is some consumer AI so bad? Instagram, for example, senses that I like bright colored clothes, then it shows me add some bright colored clothes, they’re also cheap crap that I’d never buy.

    What is the perspective of these tech companies? Is it doesn’t that work great for most people, we just need to get this right.

    For five people, it covers the cost, we know generally sucks, but it’s better than nothing.

    So it was a good question.

    The answer has a lot to do with how recommendation engine technology works, recommendation technologies, take in datasets and essentially try and find patterns in those datasets to to predict outcomes, right.

    So if we, if you like these certain things are going to predict certain other things.

    recommendation engines can use a lot of very different algorithms under the hood.

    And one of the challenges we have and it’s a challenge in the industry overall, is that a lot of these companies don’t reveal what is in their algorithm, what algorithm they’re using? Are they using something as simple as like, a naive Bayesian classifier? Are they using something as complex as you know, a many, many layer deep neural network? Are they using, you know, k nearest neighbor clustering? We don’t know.

    We don’t know what’s under the hood.

    And so we don’t we can’t necessarily offer input as to why some things behave the way they do.

    But there’s two general considerations.

    Well, three general considerations as to why some of these algorithms Don’t spit out useful stuff.

    The first by far the most likely is computational cost.

    The more complex the algorithm, the more it costs to run it.

    And the cost here is in compute computational capacity, how fast can you get the result? With a lot of ad systems for example, you were talking about millisecond response times.

    Particularly when you’re doing stuff like header bidding, and things where there is a real time auction going on.

    And ad systems have to match and generate results extremely quickly.

    And as a result, they have to pick algorithms that are super, super fast, even if the accuracy is leaves a little something to be desired.

    I mean, it’s better than nothing.

    For those who remember the early days of digital marketing, you’d be browsing on the website and you’d have like, you know, a Medicare wheelchair program being displayed to someone who’s you know, 22 and healthy.

    It’s like, no, that’s completely incorrectly targeted.

    Speaking of which, there is always the potential for advertisers themselves simply being so bad at advertising that they they have blanket targeting.

    And all the machines cannot override a user’s preferences of the the advertiser says, Hey, I want to advertise to every living person within the boundaries of this nation.

    Okay, as long as you got the budget to support it, it’s going to do that But computational cost is a big thing.

    Second thing is what data you have going in the data that goes into the system may not be robust enough to offer anything that has true predictive power.

    Especially if and this is important, especially if companies are correctly implementing ethical, unbiased AI.

    You may not for example in a lot of cases judge somebody and you know, tune your ads on a protected class or you shouldn’t be let’s put it that way.

    And so if the advertising that comes out is incorrectly targeted because you back end you know, ethical checker said, Hey, you can’t use racist as a targeting criteria for ads.

    Okay, so now you’re gonna get, you know, Sham why, even if that’s not something that you want, because there may be some balancing happening behind the scenes to ensure that the protected class is not being used.

    A third part is objective optimization.

    And this is where this is where advertisers should be a little bit concerned.

    Objective optimization and compensation models dictate how advertising networks work.

    What does the ad network get paid for? They get paid for the impression.

    Do they get paid for the click? Do they get paid for the outcome? advertisers have been pushing to very little success over the last 20 years with digital marketing to have average to have a action based or outcome based advertising where you get paid for the lead generated you get paid for the form filled out, you get paid for the shopping cart filled.

    And understandably, the big ad networks have absolutely zero interest in doing this because it means much more rigorous computation on the back end, it means much more in depth tracking.

    There may be substantial risks to the ad network because yet You could potentially, inadvertently or intentionally be collecting sensitive protected information.

    And frankly, most ad networks realize that behind the scenes, ad performance across the board is pretty crappy.

    I mean, we think about it.

    When you look at like the click through rates on some of these ads, you know, look at these campaigns, you know, when people celebrate like crazy when they get like a 5%, click through rate, which when you think about means you wasted 95% of your budget, right? If you didn’t get more than 5% of the clicks.

    From the advertiser perspective, you’re like, well, what did I pay for? If these systems were tuned to results only? advertising? It’d be a very different and much worse calculus for the ad networks because they wouldn’t get paid unless they got the result.

    Is there a possibility that companies could pivot that way, potentially.

    But right now, everything in advertising is effectively cost per impression when you look at the back end reporting and you see All these metrics in like Facebook stuff, effective cost per click, now what you’re really doing is you’re, you’re still doing all your bidding by impressions.

    And you’re still doing all your optimization on that.

    And as a result, it doesn’t really matter to the ad network, whether or not you click on the thing beyond with a reasonable doubt, but for the most part, it doesn’t matter because they’re getting paid on the impression, not getting paid a click for the most part, then definitely getting paid on the action that was taken.

    Now if advertisers forced ad networks to to pivot and said, Look, we’re not going to pay you unless you deliver results that would drastically change.

    The machine learning outcomes that allow these systems are tuned on, it would make them computationally much more expensive, because you would have to be, you wouldn’t be able to do simple stuff like k nearest neighbor clustering, just on on impressions, right? You would have to collect a lot more data, you’d have to collect a ton more data.

    And that would make for a very, very different optimization.

    When you look at how, for example, LinkedIn works versus how Facebook works for this advertising, LinkedIn stuff works very differently because they have as one of their major outcomes, we need to keep people on this professional network so that our enterprise talent management software, which is 40% of their revenue, can draw useful data from people’s profiles and recommend it to recruiters.

    It’s a, that’s an example of a system that is much more outcome based.

    And as a result, you see a very different culture on LinkedIn, you see very different advertising on LinkedIn.

    Whereas Facebook is like, show all the show every ad possible, see what people click on.

    Cool, great, whatever.

    Same with Instagram, we get paid on the view.

    So who cares what the result is.

    So that’s why consumer AI is so sometimes untuned there’s a bunch of different reasons and there’s no way to clearly tell without independent third party audits, what’s going on behind the scenes, how it’s working.

    I would love for company He’s like Facebook, for example, to reveal, hey, this is how we do the thing.

    These are the inputs.

    This is how the system is optimized.

    But that is literally their secret sauce.

    It’s unlikely that they would ever reveal that even if they could.

    Because in a lot of cases, some of these in Facebook’s case, their neural networks are so complex.

    I doubt there’s any single human could that could even interpret what’s going on behind the scenes.

    The models are just that big.

    So really good question.

    There’s a lot to unpack in here about how these algorithms work, how they’re tuned, and what’s going on underneath the hood.

    Hopefully as time goes on, we will see advertising itself pivot more towards results based advertising as well.

    You Ask, I Answer: Why Map Customer Journeys?

    John asks, “If the customer journey is different for every person, why bother trying to map it?”

    The presumption is that the customer journey is a wide open field of possibilities, when it’s more like a densely wooded forest. There are a limited number of rational pathways to conversion, and mapping both the probability and the journey itself – especially today – is worth doing. Watch the video for some examples.

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, John asks if the customer journey is different for every person, why bother trying to map it? So that’s a good question.

    Because it is true that customer journeys, maps, and customer journeys do have all these different ways people can take towards conversion and trying to force people down a rigid funnel, where they must do each step in sequence is nowadays largely a futile effort.

    Now the reason for that is pretty simple.

    It has a lot to do with this thing.

    You can be in multiple stages of different journeys just within a single device.

    I have seen people back when you were allowed to go shopping at malls and stores, talking to friends on their phones, video chatting with them, and having you know holding a piece of merchandise asking their opinions and having them do some research on Their own.

    And you know, that person for one vendor is at a certain point in the journey and another vendor is at a different point in the journey.

    And so it can be a very complex thing.

    You can be at points in the customer journey and move backwards, right? So real simple example, you’re, you’re looking at a new device or some new gadget, and you’re at the consideration phase, like, wow, this this thing looks really good, looks really cool.

    And then you read a review of it, like, ah, actually got really bad reviews.

    And you go back to like the research phase, right? And so you can be, you can move forwards and backwards and inside of a customer journey.

    Now, that said, that is at the individual level.

    The presumption in the question is that a customer journey is a wide open field of possibilities, and you can move any direction you want, you know, it’s like being in a video game, right? You can go anywhere you want, and there’s no clear direction that somebody goes and that’s not true.

    When we think about customer journeys, there is there are a limited number of ways you can rationally buy a product, right? There’s a limited number of opportunities.

    There’s a limited number of just ways you can do that.

    It’s kind of like we talked about in the martial arts a lot.

    Yes, every single person is different.

    Yes, there are hundreds of martial art styles.

    But in the end, there’s only so many ways you can punch somebody in the face that aren’t that are logical and rational, right and effective.

    And so, with customer journeys, the exact same thing is true.

    There are only so many rational reasonable ways that you can take towards conversion and that is something that you can understand in the aggregate.

    There’s an apocryphal tale of a university and I someplace supposedly in the Midwest, I’ve never actually got an answer as to whether this happened or not.

    But it seems reasonable.

    And the story goes, they did not put down any sidewalks on new campus lets students walk everywhere they wanted for a year and then paved over the most warm pathways in the grass.

    And supposedly the campus feels more natural.

    Well, extending that logic to customer journeys, if you were to know how somebody traversed either your website or how somebody traversed all the channels that are out there, towards conversion, you looked at the most walked on ones, you might get a sense of, hey, here’s how people make the journey to conversion.

    And there’s a couple different ways you can illustrate this.

    Let’s actually go ahead and bring this up here.

    So this is a customer journey analysis.

    This is a very simplistic one, where we are just looking at the channels that lead to conversion the most.

    So in this chart here we see organic search for my website drove almost 80% of traffic.

    Now, there are some debates.

    I think it’s a reasonable questions I should be asking my website if this was a major commercial enterprise, I would be at substantial risk because 80% of our traffic comes from one source That’s not a good thing.

    Good definitely did diversify my traffic sources.

    But putting that aside, I see my newsletters as number two, medium calm and number three, Twitter at number four, and Bing and number five.

    So I have five of the most popular pathways most popular channels that lead to conversion eventually.

    Now, is that the last thing that they did? No, not necessarily.

    But at least from here, I can see, these are the things that if I have to figure out how do I budget, how do I resource, what should I focus on if I want to double down on what’s working, in this case, pretty clearly I should be doing a lot more organic search.

    Right.

    Now if we wanted to make that even more fancy.

    This is a version where we have the exact same numbers but in software in web analytics software in particular.

    You can look at the the steps somebody takes on that Their journey and then just count up essentially, how many times does this appear? The first third of the journey, how many times has appeared in the second third of all those steps? How many times does appear in the last third.

    And what we see here is that organic search for me tends to peer towards the beginning.

    Whereas email and social tend to peer towards the end.

    And so people discover my site through search, stay in touch with email, and then come back to do important stuff through social media.

    That’s important that tells me from a messaging perspective Hey, your messaging on things like social media, it’s okay for you to have you know, more closing language in in my content because it tells me that people are ready or more ready to convert from those than they are from say, like organic search, or even email I have to give some thought here to my email marketing, should I be pressing that hard to get people to convert? Or should I be nurturing? The relationship with the intent of eventually using social media to get them to close.

    So these are two examples of customer journey maps that I built for my website.

    This is actually a service that I offer through my company Trust Insights.

    If you’re interested in having this done for your company, go to Trust insights.ai.

    I will tell you right now, it is reassuringly expensive.

    So it will do a good job of giving you the strategic blueprint you need for what’s working, and how it’s working.

    But to go back to John’s question, there are only a certain number of ways as you can see here, where people convert, right, that journey is not completely irrational, right? And there’s not traffic everywhere and people just wandering off on their own.

    There are distinct sequences that people take towards conversion and those distinct sequences are things that we can know and address and serve at 90 95% of our audience.

    serve them well.

    By investing properly by messaging properly in the channel groupings, where it makes sense to do so.

    And understanding what it is that we should be doing more of I should potentially be diversifying a bit, right? Maybe I should do a little bit more email, maybe I should try some ads.

    I am doing well, organic search, I need to continue to do well and stuff.

    So that want to double down on what’s working and want to shore up the stuff that isn’t working to the extent that we can.

    So that’s why you would do customer journey mapping.

    That’s why you bother trying to map it because it can give you aggregate insights that can guide your strategy.

  • You Ask, I Answer: The Future of Content Marketing?

    You Ask, I Answer: The Future of Content Marketing?

    Stephanie asks, “How do you see content marketing evolving in the future?”

    AI will produce much more of it, and our role will be as prompters and editors. We already see this with tools like Nvidia’s GauGAN, the GPT family of language generators, and the AIVA music composition system. When you look at the quality that engines like Unreal 5 can produce, cinema-level capabilities will be in reach for more and more creators at affordable budgets. Eventually, the best ideas will win, unconstrained by talent.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, Stephanie asks, How do you see content marketing evolving in the future? Well, so there’s gonna be a bunch of things that are gonna happen already happening.

    Artificial intelligence and machine learning will be producing much more of the content that we create on a regular and frequent basis.

    And that will change our roles as the humans we will.

    As I’ve said many times in various talks, we will not be the first violin anymore, we will be the conductor of the orchestra, with the understanding that you only need one conductor of an orchestra where you can have you know, 100 people in the orchestra.

    99 of those jobs will eventually be held by machines in some capacity.

    And so our role will be to be the conductor’s be the prompters and the editors.

    So there are already some incredible tools like Nvidia’s Gao Gan, which does machine assisted painting GPT, the GPT family GPT One, two and three from open AI that do incredible natural language generation and code generation.

    Eva and wavenet not wait ml net that do audio synthesis.

    So there’s already a lot of tools out there today that are accessible today.

    That can generate a lot of content.

    Eva in particular does really nice, good enough music right for commercial applications in a way that sidesteps a lot of the licensing issues because it’s, you know, it’s all original machine generated works that sound okay, they all sound great, but not going to win a Grammy.

    But if you need background music to like your podcast, whatever, you will use that And so our role as the people will be to prompt the machines, as we see with Eva and with GPT three, to say, Hey, this is what I want.

    You go do it, right.

    And then we will be the editors and the QA people to inspect the models to inspect their outputs and say, You know what, this wasn’t what I was after.

    But I queue up a song and Eva, I’ll load up an influence and I’ll listen to the five compositions it creates and you know, one out of five will be good.

    Four out of five, three out of five will be mediocre too bad and one of them would just be hilariously bad like now that that’s not at all what I had in mind.

    And that’s going to be our role for the foreseeable future once these tools become more affordable, easier to use more widespread is the the beginning end Yeah, I suppose.

    A nice racing prompter be the content strategist, where it is actually true strategy.

    What do we need? What does the market need? What can we provide? Have the machines do it? And then we inspect the outputs and say yes or no, that was what we had in mind or that was not what we had in mind.

    When we look at what’s happening on the quality side, the quality side is unbelievable.

    I was watching a demo of the Unreal five engine for PlayStation five, and it is generating in near real time cinematic experiences.

    Now these are reserved today for triple A games, right? The big studios with the big budgets can use these to generate real realistic looking environments that are are so good, you wouldn’t know that you were playing a game except to the interface elements.

    The same thing is true of things, even even non machine learning driven tools and techniques like you know when you look at at FIFA 20 or Madden 20 on these gaming platforms, if you didn’t know that you were watching somebody play a game.

    From a distance, you might think you’re just watching a regular football game or a regular soccer game.

    And so, cinema level capabilities will be in reach for more and more creators at more affordable price points.

    Again, the top of the line today is is for the triple A studios.

    But what was top of the line five years ago for for triple A students is now a studios is now available in you know, the entry level production capabilities.

    So, all of this to say that for content marketing and its evolution, the tools are constantly getting better, sometimes making substantial leaps forward, the research, the capabilities, all the things that go into making content are getting better.

    And where the bottleneck is and probably will be for some time is going to be around the people in the processes the technology is doing just great.

    Is our limitations as people that hold our content marketing back and will continue to hold it back.

    We have to pivot from being the doers to being the coordinators, we have to pivot from being the tactician to the strategists.

    And ultimately, we have to figure out who among us has actual creative capabilities in terms of creative ideas, because when all the tools are the same, and when all the tools are really good, the best ideas will be the ones that when unconstrained by talent, if you don’t need to know how to paint, but you have an idea for a painting, and you can get a machine to do the painting, then your idea can come to life.

    If your musical concept is something that you care deeply about, but you don’t know how to score music and you don’t know how to play music.

    Again, not as much of a big deal.

    You can have a machine help you with the mechanics of that And so, for content marketers, the senior level ones be thinking a lot more strategically be thinking a lot more conceptually coming up with big ideas for more junior ones, learn how to be the conductors of the orchestra, learn how to run machines, so that there is still a role for you.

    Learn how to QA the output of the machines and understand when the machines are not behaving and why they’re not behaving and what they should what you should be doing with them.

    And for everyone, learn how to analyze data and understand what the market wants what the audience wants, so that you can direct the machines to create the things that that they want and satisfy their needs.

    That’s the future of content marketing.

    And it is a future in which those who have important roles, the strategists the prompters the coordinators, the editors, the QA folks, I believe will make a good living, because they will be very effective at what they do with the understanding that there may not be as many seats at the table going forward.

    When you can have a machine spit out five new songs every 30 seconds, even if only one out of five is good.

    Do you need to have more than one or two musicians on staff to QA it and to make adjustments to it? The answer is probably no.

    I was playing around with music composition, I sent it to a friend whose images and they were able to take the the output file loaded straight into their digital audio workstation, tweak it and say yep, here’s the adjusted version took me about 10 minutes to to QA and adjusted but what the machines spit out was good enough for our purposes.

    That’s what it says even the future that’s today.

    That’s right now and what we have Continue to trend forward into more and more machines doing the the grunt work and us doing the coordination in the strategy.

    so plan accordingly.

    It’s going to be an interesting future.

    It’s going to be a fun future but it will also be a challenging future because they will not be as many seats at the table.

    You Ask, I Answer: What Makes Effective Facebook Ads?

    Jen asks, “How can brands find out which kind of Facebook Ads work best for them?”

    One way to approach this problem is with large scale data analysis. In your industry, gather up a list of Facebook Pages and use any service which can address the Facebook API like Facebook’s Crowdtangle, then filter to only sponsored posts. Sort by engagement, and then begin the work of analyzing what sets the top 10% apart from the rest. Is it copy? Imagery? Timing? Audience size?

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, John asks, How can brands find out which kind of Facebook ads work best for them? Interesting question, the way that I think you would tackle this problem, or at least one way that you could tackle this problem was with large scale data analysis.

    The Facebook API does allow some limited extraction of data.

    And there are certainly plenty of services, competitive social media monitoring services, Facebook data services.

    One example is Facebook’s CrowdTangle service that allow you to extract large amounts of information that’s publicly facing publicly available, including advertising, and then do some analysis on it.

    So one approach you could take would be to go to one of these services, put in your company’s Facebook page, put in a list of all the major competitors.

    You have in Your space.

    Maybe some companies have functionally similar business models to you.

    So for example, if you’re a coffee shop, you might put in like tea shops and pizza shops and things like that.

    And extract out all the Facebook posts paid and unpaid that these companies have run in the last, you know, however long and then sort it.

    Look at which of the the pieces of content that were paid, and then assess what worked.

    What resonated.

    Now, with this technique, you won’t get every single ad because they’re certainly you know, there’s so many different types, but you will get thematically, the types of messaging and imagery and copy and timing and audience sizes.

    For what’s working best in that sector.

    It may be, you know, five or 10% of all the content available for your industry, but that’s enough to give you a sample that looks like Okay, these are the things that seemed to work.

    Maybe it’s images of a certain type, or even a color palette, maybe it’s a day of the week or an hour of the day.

    When you have that large scale data set, you can look at what is in the top five or 10 or 20% of the data and say, Okay, what got engagement? What got people interested? Is it and are those things unique? Now, here’s the challenge.

    The data is only semi ready to analyze, there’ll be some things that you can obviously look at right away engagement types, you know, likes, comments, shares, the different reactions, you’ll be able to get URLs to the various images, but then you’re gonna have to spend a fair amount of time as a human or team of humans, manually appending some of the information so you’ll need to, for example, look at the imagery on the post.

    And then maybe, in this, think of it as a spreadsheet, you’d have to add columns for like what types of images are in there and you’d have to be somewhat similar Like, you know people cars, coffee cops, silly clipart drawings, whatever the image type is you need to manually note that in the spreadsheet, you would also need to append because you won’t get the text of the comments, general themes in comments if people have left comments at all.

    And for those comments you would need to append and say like this is generally positive, generally negative, things like that.

    That manual augmentation of the data is essential in order to make this process work because there is a lot to a Facebook ad that is not immediately visible to a machine, right, again, systematically understand what are the themes of the images, particularly if you’re looking at images across different pages.

    Again, using the coffee shop example if you have Starbucks and Dunkin Donuts and things like that they may have their own visual palette that is unique to their brand that you would not be able to replicate, you’d have to use your own design palette to do that.

    But the ability for you to at least get a head start with the the raw data itself, and especially the engagement data is where you’re going to get a lot of value out of this procedure.

    Now, again, this is not every ad type, this is going to be mainly things like sponsored posts and stuff, but it’s a good starting point.

    Because if you can’t get any traction at all on a sponsored post where the engagement rates are so terrible, then you know that whatever ad strategies are currently being used out, there may not necessarily be all that effective.

    There are other tools that can pull in some fate, some social media advertising data as well.

    I haven’t used them in a while.

    So I know back in the day, I believe sem rush did that.

    But you can look at comparable performance of Google ads.

    Also to see from a messaging perspective, are there common themes, tools like sem rush and spy? Are refs all? Do they have the ability to extract out that type of data? And one of the things you could test is, does a ad copy, theme, title, etc? That works on Google ads? also work on Facebook here? Are they similar audiences are different audiences.

    One way to tell this for your own brand page is to look at your Google Analytics, demographics data, look at your Facebook Audience Insights, demographics, data.

    And if there’s a wide disparity on basic things like age and gender, then you know that you don’t have the same audience and what works in say, one platform may not work on the other.

    On the other hand, if there’s substantial overlap between the two audiences, there’s a good chance that if something’s working for you, or a competitor in your Google ads, that may also have applicability in your Facebook ads.

    So there are a lot of ways to attack this problem with data to try and determine what are the things that could work or should work and build a testing plan.

    That’s the important thing is the next step in this process is not just William nilly stop start copying things you want to build an actual testing plan, that is an A B test, where you have a would be the ads, you would have run anyway.

    And B would be these new ads that you have designed based on the data you found.

    And you run them in parallel, same audiences, same budget span, same timeframe, etc, to see which ad set works better.

    When you do that, you’ll have a sense over a fairly long period of time about whether your data driven approach is a better approach than the normal creative that you would have done otherwise, depending on the skill of your creative team.

    And depending on the the themes and the data you get out from your competitors, you may not find an advantage, you may find that the data driven approach works worse because your competitors suck.

    And you’re drawing on data that they’ve produced.

    So be aware of that possibility.

    Just because you’re using data does not guarantee a better result.

    On the other hand, if you have a creative team like me that can barely put together a stick figure art, the data driven approach probably is going to work better for you.

    Because you’ll be able to pick up on themes and use your reasonable commercially available clipart and stuff to make better stuff then your incompetent, creative team I was putting together again referring to myself here.

    So that’s the approach.

    Do the data analysis, identify the common themes, build a testing plan, run the testing plan and see which performs better? with the understanding that the data you find may not be all that high quality? Good follow up questions on this, please leave them in the comments box below.

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, Heidi asks, ted.com published a list of the Top 10 careers to stay employed through 2030, including socially distanced office designer and virtual events planet, what do you make of their predictions? Well, in looking at these and I’ll put a version up here.

    A lot of these are very short term thinking very short term, and they’re very pandemic centric.

    The pandemic isn’t going away anytime soon.

    But it is going to be with us for only a couple of years, probably two years or so.

    That’s the time it will take to develop a vaccine and get it broadly distributed around the world.

    And yes, some countries definitely will lag behind others will be more vulnerable than others.

    Places like Europe will do well.

    Asia, China, Japan, Korea will do well.

    Places like the United States will not do well are already seeing, you know, massive anti vaccine movements and such.

    And so it will take longer for the United States to recover.

    But it still won’t be the full decade.

    Soon.

    So what should we be thinking about in terms of these careers, things like chief purpose planner or clean hygiene consultant or virtual events planner, subscription management specialist, they are there to tactical and not thinking about the technologies that are available to us now and what’s in development and where that’s going to go.

    So for example, we know things are not going to change, right? People will still need places to live, people will still need food to eat, people will still need, you know, things to do.

    Kids will still need educating.

    these are these are things that are not going to change a whole lot.

    What will change is the tactics that we use To deliver those services, and a lot of it is going to be around artificial intelligence, not because it’s trendy, but because frankly, it’s a cost saver.

    We know that in business in, you know, b2b business, and all business really.

    companies want things to be the same as consumers better, faster and cheaper.

    And machines and automation and AI are the pathway to delivering things that are better, faster and cheaper, because you can have machines do stuff better and faster, and at a substantially lower cost than humans.

    In that sense, there will be a lot of evolution of AI models and how they’re deployed to having people be able to customize them, to tune them to run them to be able to offer a lot more customization to be able to offer a lot more specialization.

    And so it would not be for example, I think out of the realm of possibility to have You know, friendly user interfaces on top of AI models that allow you to accomplish tasks that you’re trying to get machines to do.

    So for example, in brokering a real estate transaction, do we need a real estate agent in the mix? For some parts, maybe some parts, no, some parts, some of the paperwork and some of the very repetitive processes, permits and titles of all this stuff, machines can absolutely do that.

    A big part of that will be cleaning up and getting local government technology.

    You know, sometime into the century, a lot of local governments tend to lag very far behind the commercial sector.

    So there there’s actually a decent cottage industry to be had for government automation.

    And then we look at other things that people are going to be doing driving cars, probably not a whole lot in the next 10 years.

    If you look at the way that autonomous vehicles function, now today, and 2020 they are almost ready for primetime.

    Now, they still need some more testing, they still need some deal with like adversarial attacks on their on their models, but for the most part they’re functional.

    Now, within 10 years, assuming that, again, government regulation permitted, you’ll have many more of those, you will have a thriving career in law, dealing with the ways that machines are changing technology.

    So for example, when we look at systems like Eva and GPT, three, they can reinterpret and create new works out of existing works derivative works that are not necessarily traceable back to the original.

    So how does that impact law? How does that impact copyright? How does that impact creators rights? When a machine a model creates something new who owns that? Do you as the model owner, do you as the service provider does the end user owner these are all questions that law will need to address in order to deal with Be implications.

    There will be large questions about who owns user data.

    There already are.

    But in the next 10 years, we should expect to see at least some answers.

    And as we see with things like GDPR and privacy legislation, it will be a patchwork quilt around the world who gets to own what, but there will be many careers grown on that.

    I think an AI console years of sorts, someone who is so can function in that low code environment, to help businesses and even maybe even wealthy individuals customize their models and their technology will be a cottage industry.

    If you are the sort of company or environment they use things like virtual assistant true virtual assistants, like the little things on your desk here.

    That you just yell at for groceries.

    Those are have very limited customization right now and there is no transfer Apparently as to how the customizations work, having people be able to customize it to your particular use cases, even if it’s just something as simple as, for example, with transcription software, uploading a list of known words that you say that are kind of unique to your use case.

    That’s a level of customization that a lot of smart assistants do not offer currently.

    And that’s something that obviously a lot of people would find a lot of value in.

    Being able to get technology to people is is still a thing.

    Elon Musk’s interlink satellite network is trying to address the fact that in large swaths of remote areas and rural areas around the world, there simply is no internet.

    And having low Earth orbit satellites to allow access while you’re in those areas may not be fast enough for zoom call or play video games, but it would be enough to get you connectivity and continue networking the rest of the planet over the next 10 years.

    That’s going to be a priority.

    And so there will be careers around that.

    And there’ll be careers around all those new consumers and businesses that are suddenly have connectivity.

    There will be places in Asia and Africa, in the United States, North America, South America, every continent on the planet that will suddenly have access to the Internet, and will want to participate.

    And I think there will be a substantial number of careers around the implications of different AI models and how we deal with them everything from detecting bias in datasets, and dealing with AI ethics and how machines make decisions and what the right decisions are.

    There’ll be plenty of consulting to be had around risk mitigation for companies if you publish a model.

    What are the risks of it, have you mitigated against them? Have you been audited to demonstrate that you have protected against those risks? If we To the the avenue that I would like to see companies take wishes that machine’s not humans, but machines are guilty until proven innocent of things like bias or discrimination.

    Then again, there’ll be a very large cottage industry of people who can help make models more interpretable.

    And then to validate that the model is actually doing what we said it would do that is not discriminating against protected classes of any kind.

    So those are just a few samples of the of things you should think about.

    Now, virtual events plan Asscher for the next couple of years, that will be a thing.

    But human nature is such that people like to get together.

    And so I think that career will be a cottage industry is not going to be at zero, but it will not be something that will sustain you all the way through the next decade.

    In the same way that something like risk management around AI certainly could.

    So really good question.

    Lots to think about.

  • You Ask, I Answer: Content Marketing Topic Research?

    You Ask, I Answer: Content Marketing Topic Research?

    Erika asks, “What are your tips and best practices for topic and keyword research in content marketing?”

    It depends on the size of the content and how much domain expertise you have. Scale your research efforts to the level of risk the content poses and how important it is that you get it right.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    In today’s episode, Erica asks What are your tips and best practices for cop topic and keyword research and content marketing? So this is an interesting question because the answer is dependent upon a couple things on the size of the content, but more importantly on the domain expertise and how much risk there is in the content.

    Remember that while we are writing to be found to be seen, we are also writing to have our information be used by people and that means that there is an inherent level of risk in content.

    The level of risk is proportional to the amount of domain expertise we need to have.

    So if I’m, I’ve been asked to write a piece of content on I don’t know, number of characters in the tweet or you know how to emoji in Influence tweets.

    That’s a relatively low risk piece of content, right? It doesn’t require a ton of research.

    And identifying topics and keywords and things for it is pretty straightforward.

    I’m probably not going to screw that up.

    And even if I do, it’s going to be very low impact, right? If somebody uses the poop emoji instead of the heart emoji, it’s not going to be probably the end of the world.

    On the other hand, if I’m being asked to create a white paper, or a video series about important steps to take for protecting yourself against a pandemic, that piece of content could literally be life or death for somebody and so I would need to have much greater domain expertise.

    I would need to invest a lot more time in understanding the topic overall first, before even trying to cobble together keywords and things to understand all the pieces that are related to it.

    And I would want to take a whole bunch of time to get background, academic papers, books, videos, studies, research, all that stuff that will tell me what is the shape of this thing? What is the? What are the implications? And mostly what is the lexicon? And what is it that experts in the field think Who are those experts? What else do they talk about? What are the related topics? So that’s the first step is to assess your level of risk and what level of domain expertise you’re going to meet.

    Then you look at the size of the content.

    How much are we talking about? We’re talking about like five tweets.

    Are we talking about a 1500 word blog post, a 10 minute video, 45 minute class, a four hour workshop or a white paper, something that you intend to be in an academic journal, a book on Amazon? What is the size of the content, the bigger the size The more research you’re going to need, the more data you’re going to need.

    And then you can look at things like, you know, keywords.

    One of the best sources for keywords, and for topics and understanding the topic is actually speech, people talking, because in things like podcasts, and videos and interviews and stuff, you will get a lot more extraneous words, but you will get you will also get more of the seemingly unrelated terms.

    So let’s talk for example, about SARS-CoV-2, the virus that causes covid 19.

    In listening to epidemiologists and virologists talk about this thing.

    Yes, there are the commonplace topics like you know, wearing masks, for example, would be something that would be associated with this topic.

    Washing your hands would be something you’d be associated with this topic, keeping a certain distance away from people.

    But you would also see things like co2 measurement How, how much co2 is in the air around you, because it’s a proxy for how well event ventilated space is, the better a spaces ventilated, the less co2 will be in, compared to, let’s say, the outdoor air.

    And so you’ll see measurements like you know, 350 parts per million 450 parts per million.

    And these are not topic, these are not keywords that you would initially See, if you’re just narrowly researching the topic of COVID-19.

    These are important, right? These are things that you would want to include in the in an in depth piece of research, you might want to talk about antigens and T cells and B cells and how the immune system works.

    Those are equally be things.

    So, again, this is a case where you have a very complex topic which requires a lot of domain expertise.

    And mapping out though, the concepts will be an exhaustive exercise as it should be because again, you’re creating content that is If you get it wrong, and you recommend the wrong things, you could literally kill people with it.

    So that would be the initial assessment, domain expertise, how much content you’re going to need? What are the risks? after that? You need a solid content plan, how much content what’s the cadence? What are the formats, it’s going to be distributed in a topic and keyword research list is less important.

    still important, but less important for something like a podcast, right? Unless you’re producing a transcript, in which case, it’s you’re back to creating, making sure that you’re mentioning certain specific terms.

    And you’d want to make sure that you you do that in the context of the show.

    One of the things that Katie Robbert and I do before every episode of Trust Insights podcast is look at the associated keywords for a given topic and see other things that from a domain expertise perspective, we are lacking.

    That would want to augment and verify and validate that we’re going to mention in the show because we also publish it as a video, though, that means those keywords and those topics make it into the closed captions file, which means that YouTube can then index it better and shorter video more.

    In terms of the tools that you would do this, use this for this, it depends on the content type.

    So some things like PDFs are not natively searchable.

    In a text format, you have to use a tool like Acrobat or preview or something.

    So there are tools that will export a PDF to a plain text file and then you can do your normal text mining.

    Text mining tools will be essential for digesting a body of content in order to understand the keywords and topics.

    There are, there’s a library I use in the programming language are called quanta.

    That does an excellent job of extracting out here the key words in context and the keywords that are within this large group of documents.

    So you would take for example, blog posts, Reddit posts, academic papers, cover them all in plain text, load them into this piece of software, as a piece of software would digest them all down and say here are the, here’s a map of, of words that exist in this universe and how they’re connected, which is really important because a lot of tools can do you know, a word cloud, that’s easy, but you don’t understand necessarily the connections between terms.

    So for example, you know, a T cell and B cell would be connected terms within the immune system.

    In a paper about COVID-19.

    You’d want to know that to see how those topics relate to each other social media posts, transcripts, from YouTube videos, transcripts, from podcasts, all those things.

    That level of text mining will give you greater insights into the universe around the topic.

    In addition to the core keywords themselves, one of the problems with a lot of keyword software is that it’s very narrowly restricted like you can use you know, all male contains these terms or This phrase, but again, something about COVID-19 is not necessarily going to have a key word like antigen, or a key word like dexa, methadone, right? Very important concept, but not necessarily going to be immediately related, which is what a lot of more primitive keyword tools do.

    So I would use some text mining tools to extract out and map the universe of language around a topic.

    Then you can start creating content from and lining up, you know, if you’re going to be doing a top a piece of content about espresso and what are all the terms that go with espresso, and then you can see the how they clustered together.

    And that creates your anchor content to cover each of the major concepts.

    So a lot in there a lot to think about, but do that risk assessment and that domain expertise assessment first that will govern the size of your project and how much research you need to do? If you have follow up questions, leave in the comments box below.

  • You Ask, I Answer: Twitter Bot Detection Algorithms?

    You Ask, I Answer: Twitter Bot Detection Algorithms?

    Joanna asks, “In your investigation of automated accounts on Twitter, how do you define a bot?”

    This is an important question because very often, we will take for granted what a software package’s definitions are. The ONLY way to know what a definition is when it comes to a software model is to look in the code itself.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    Email.

    In today’s episode, Joanne asks, in your investigation, automated accounts on Twitter, how do you define a bot? So this is really important question.

    A lot of the time when we use software packages that are trying to do detection of something and are using machine learning in it, we have a tendency to just kind of accept the outcome of the software, especially if we’re not technical people.

    And it says like, this is a bottle.

    This is a knob, which kind of accept it as really dangerous is really dangerous because it’s not clear how a model is making its decisions, what goes into it out as it makes its decisions.

    How accurate is it? And without that understanding, it’s very easy for things like errors to creep in for bias to creep in.

    For all sorts of things to go wrong and we don’t know it.

    Because we don’t know enough about what’s going on under the hood to be able to say, Hey, this is clearly not right, except to inspect the outputs.

    And then again, if you’re not technical, you are kind of stuck in the situation of either I accept that the outputs are wrong or I find another piece of software.

    So, in our Saturday night data parties that we’ve been doing identifying Twitter accounts that may be automated in some fashion, there are a lot of different things that go into it.

    Now, this is not my software.

    This is software by Michael Kennedy from the University of Nebraska.

    It’s open source, it’s free to use it’s part of the our, it’s in our package, so uses the programming language.

    And that means that because it’s free and open source, we can actually go underneath, go under the hood and inspect to see what goes in the model on how the model works.

    So let’s, let’s move this around here.

    If you’re unfamiliar with open source software, particularly uncompetitive Which the our programming language is a scripting language and therefore it is uncompelled.

    It’s not a binary pieces of code, you can actually look at not only just the software itself, right and explain, the author goes through and explains how to use the software.

    But you can, if you’re, again, if you’re a technical person, you can actually click into the software itself and see what’s under the hood, see what the software uses to make decisions.

    This and this is this is why open source software is so powerful because I can go in as another user, and see how you work.

    How do you work as a piece of software? How are the pieces being put together? And do they use a logic that I agree with now? We can have a debate about whether my opinions about how well the software works should be part of the software, but at the very least, I can know how this works.

    So let’s Go into the features.

    And every piece of software is going to be different.

    This is just this particular author’s syntax and he has done a really good job with it.

    We can see the data it’s collecting.

    If I scroll down here, like since the last time time of day, the number of retweets number of quotes, all these things, the different clients that it uses, tweets per year, years on Twitter, friends, count follows count ratios.

    And all these are numeric.

    Many of these are numeric features, that you get the software’s going to tabulate and essentially create a gigantic numerical spreadsheet for it.

    And then it’s going to use an algorithm called gradient boosting machines to attempt to classify whether or not an account is is likely about based on some of these features, and there’s actually two sets of features.

    There’s that initial file and then there’s another file that looks at things like sentiment tone, uses of different emotions and emotional keywords and the range the it’s called emotional valence, the range of that within an author’s tweets.

    So if you’re sharing, for example, in an automated fashion a particular point of view, let’s say it’s, it’s a propaganda for the fictional state of wadiya, right from the movie the dictator, and you are just promoting Admiral General aladeen over and over and over again and you’re gonna have a very narrow range of emotional expression, right? And there’s a good chance you’re going to use one of these pieces of scheduling software, there’s good chance that you will have automated on certain time interval.

    And those are all characteristics that this model is looking for to say, you know what this looks kind of like an automated account, your posts are at the same time every single day.

    The amount of time between tweets is the exact same amount each time.

    The emotion range, the context is all very narrow, almost all the same, probably about as opposed to the way a normal user a human user functions where the, the space between tweets is not normal, it’s not regular, because you’re interacting and participating in conversations, the words you use and the emotions and the sentiment of those words is going to vary sometimes substantially because somebody may angry you or somebody may make you really happy.

    And that will be reflected in the language that you use.

    And so the way the software works, is essentially quantifying all these different features hundreds of them, and then using this this machine learning technique gradient boosting machines to build sequential models of how likely is this a contributor to a bot like outcome? How regular is this, this data spaced apart? Now the question is, once you know how the model works, do you agree with it? Do you agree that all these different things Factoring sticks are relevant.

    Do you agree that all of these are important? In going through this, I have seen some things that like, I don’t agree with that.

    Now, here’s the real cool part about open source software, I can take the software, and what’s called fork it basically make a variant of it, that is mine.

    And I can make changes to it.

    So there are, for example, some Twitter clients in here that aren’t really used anymore, like the companies that made them or have gone out of business.

    So you won’t be seeing those in current day tweets, we still want to leave those in big for historical Twitter data.

    But I also I want to go into Twitter now and pull a list of the most common Twitter clients being used today and make sure that they’re accounted for in the software, make sure that we’re not missing things that are features that could help us to identify the things I saw in the model itself, they made a very specific choice about the amount of cross validation folds in the in the gradient boosted tree.

    If that was just a bunch of words you crossed validation is basically trying over and over again, how many times you we run the experiment to see, is the result substantially similar to what happened the last time? Or is there a wide variance like, hey, that seems like what happened these two times or three times or however many times it was random chance, and is not a repeatable result.

    They use a specific number of the software, I think it’s a little low, I would tune that up in my own version.

    And then what I would do is I would submit that back to the authors of like a pull request, and say, Hey, I made these changes.

    What do you think? And the author go? Yep, I think that’s a sensible change.

    Yep.

    I think I’ve tweeted a client should be included.

    Now, I disagree with you about how many iterations we need or how many trees we need, or how many cross validation folds we need.

    And that’s the beauty of this open source software is that I can contribute to it and make those changes.

    But to Joanne’s original question.

    This is how we define a bot.

    Right? The software has an algorithm in it and algorithm, as my friend Tom Webster says is data plus opinions, data plus opinions that we choices we make.

    And so by being able to deconstruct the software and see the choices that were made, the opinions that were encoded into code and the data that it relies on, we can say, yes, this is a good algorithm, or no, this algorithm could use some work.

    So that’s how we define a bot here.

    Maybe in another Saturday night data party will actually hack on the algorithm some and see if it comes up with different results.

    I think that would be a fun, very, very, very, very technical Saturday night party.

    But it’s a good question.

    It’s a good question, I would urge you to ask all of the machine learning systems that you interact with on a regular basis, all the software you interact with on a regular basis.

    Is there a bias? Is their opinion being expressed by the developer? What is it and do you agree with it? Does it fit your needs? And if it doesn’t, you may want to consider a solution like open source software where you can customize it to the way you think the system should function.

    So good question.

    Jim asks, “Are there any resources that evaluate marketing platforms on the basis of how much racial and gender bias is inherent in digital ad platforms?”

    Not that I know of, mostly because in order to make that determination, you’d need access to the underlying data. What you can do is validate whether your particular audience has a bias in it, using collected first party data.

    Machine-Generated Transcript

    What follows is an AI-generated transcript. The transcript may contain errors and is not a substitute for watching the video.

    Veeam in today’s episode, Jim asks, Are there any resources that evaluate marketing platforms on the basis of how much racial and gender biases inherent in digital ad platforms? So Not that I know of, mostly because in order to make a determination about the bias of a platform, you need to look at three different things, right, you need to look at the data set that’s gone in it, the algorithms that have been chosen to run against that.

    And ultimately, the model that these these machine platforms use in order to generate results.

    And no surprise, the big players like Facebook or Google or whatever, have little to no interest in sharing their underlying data sets because that literally is the secret sauce.

    Their data is what gives their machine learning models value.

    So what do you do if you are concerned that the platforms that you’re dealing with may have bias of some in them, well first, acknowledge that they absolutely have bias.

    And then because they are trained on human data and humans have biases.

    For the purposes of this discussion, let’s focus on.

    Let’s focus on the machine definition of bias, right? Because there’s a lot of human definitions.

    The machine or statistical definition is that a bias is if something is calculated in a way that is systematically different than the population being estimated, right? So if you have a population, for example, that is 5050.

    And your data set is 6044.

    At any statistic, you have a bias, right? It is systematically different than the population you’re looking at.

    Now, there are some biases, that that’s fine, right? Because they’re not what are called protected classes.

    If you happen to cater to say people who own Tesla cars, right? Not everybody in the population has a Tesla car.

    And so if your database is unusually overweight in that aspect, that’s okay that is a bias, but it is not one that is protected.

    This actually is a lovely list here of what are considered protected classes, right? We have race, creed or religion, national origin, ancestry, gender, age, physical and mental disability, veteran status, genetic information and citizenship.

    These are the things that are protected against bias legally in the United States of America.

    Now, your laws in your country may differ depending on where you are.

    But these are the ones that are protected in the US.

    And because companies like Facebook and Google and stuff are predominantly us base, headquartered here, and are a lot of their data science teams and such are located in the United States.

    These are at the minimum the things that should be protected.

    Again, your country, your locality, like the EU, for example.

    may have additional things that are also prohibited.

    So what do we do with this information? How do we determine if we’re dealing with some kind of bias? Well, this is an easy tools to get started with right, knowing that these are some of the characteristics.

    Let’s take Facebook, for example, Facebook’s Audience Insights tells us a lot about who our audience is.

    So there are some basic characteristics.

    Let’s go ahead and bring up this year.

    This is people who are connected to my personal Facebook page and looking at age and gender relationship and education level.

    Remember that things like relationship status and education level are not protected classes, but it still might be good to know that there is a bias that the the, my data set is statistically different than the underlying data.

    Right.

    So here we see for example, in my data set, I have zero percent males between the ages of 25 and 34.

    Whereas the general population there is going to be like, you know, 45% of give or take, we see that my, in the 45 to 54 bracket, I am 50% of that group there.

    So there’s definite bias towards men there, there is a bias towards women in the 35 to 50 to 44 set is a bias towards women in the 55 to 64 set.

    So you can see in this data, that there are differences from the underlying all Facebook population, this tells me that there is a bias in my pages data now, is that meaningful? Maybe, is that something that I should be calibrating my marketing on? No, because again, gender and age are protected classes.

    And I probably should not be creating content that or doing things that potentially could leverage one of these protected classes in a way that is illegal.

    Now, that said, If your product is or services aimed at a specific demographic like I sold, I don’t know, wrenches, right, statistically, there’s probably gonna be more men in general, who would be interested in wrenches than women.

    not totally.

    But enough, that would be a difference.

    In that case, I’d want to look at the underlying population, see if I could calibrate it against the interests to see it not the Facebook population as a whole.

    But the category that I’m in to make sure that I’m behaving in a way that is representative of the population from a data perspective.

    This data exists.

    It’s not just Facebook.

    So this is from I can’t remember what IPAM stands for.

    It’s the University of Minnesota.

    they ingest population data from the US Census Bureau Current Population Survey.

    It’s micro data that comes out every month.

    And one of the things you can do is you can go in and use their little shopping tool to pull out all sorts of age and demographic variables including industry, and what you weren’t, you know, and class of worker, you can use this information.

    It’s anonymized.

    So you’re not going to violate anyone’s personally identifiable information, but synonymous.

    And what you would do is you would extract the information from here, it’s free look at your industry, and get a sense for things like age and gender and race and marital status, veteran status, disability, and for your industry get a sense of what is the population.

    Now, you can and should make an argument that there will be some industries where there is a substantial skew already from the general population, for example, programming skews unusually heavily male.

    And this is for a variety of reasons we’re not going to go into right now but acknowledge that that’s a thing.

    And so one of the things you have to do when you’re evaluating this data and then making decisions on is, is the skew acceptable and is the skewed protected, right? So in the case of, for example, marital status marital status is not a protected class.

    So is that something that if your database skews one way or the other doesn’t matter? Probably not.

    Is it material to your business where we sell, for example, Trust Insights, sells marketing insights, completely immaterial.

    So we can just ignore it.

    If you sell things like say wedding bands, marital status might be something you’d want to know.

    Because there’s a good chance at some of your customers.

    Not everybody goes and buys new rings all the time.

    Typically, it’s a purchase happens very, very early on in a long lasting marriage.

    On the other hand, age, gender, race that are those are absolutely protected classes.

    So you want to see is there a skew in your industry compared to the general population and then is that skew acceptable? If you are hiring, that skews not acceptable, right? You cannot hire for a specific race.

    Not allowed.

    You cannot have For a specific age, not allowed.

    So a lot of this understanding will help you calibrate your data.

    Once you have the data from the CPS survey, you would then take it and look at your first party data and like your CRM software, your marketing automation software, if you have the information.

    And if you have that information, then you can start to make the analysis.

    Is my data different than our target population? Which is the group we’re drawing from? Is that allowed? And is it materially harmful in some way? So that’s how I would approach this.

    It’s a big project and it is a project that is you have to approach very, very carefully and with legal counsel, I would say, if you are, if you suspect that you have a bias and that that bias may be materially harmful to your audience, you should approach it with legal counsel so that you protect yourself you protect your customers, you protect the audience you serve, and you make sure you’re doing things the right way.

    I am not a lawyer.

    So good question.

    We could spend a whole lot of time on this.

    But there’s there’s a lot to unpack here, but this is a good place to start.

    Start with populate Population Survey data.

    Start with the data that these tools give you already and look for drift between your population and the population you’re sampling from your follow up questions, leave them in the comments box below.
