    You Ask, I Answer: Vetting Marketing AI Vendors for Bias?

    Tracy asks, “What are some questions you should ask vendors to better understand what data they use in their algorithms to make sure it’s not biased?”

    It’s not just questions we need to ask. Consider checking for bias to be like any other audit or due diligence. We will want to investigate the 6 main areas where bias creeps in: people, strategy, data, algorithm, model, and action/deployment. How do you do this? A lot of it comes down to vendors producing documentation. If they can’t, there’s likely a problem.

    In today’s episode Tracy asks, what are some questions you should ask vendors to better understand what data they use in their algorithms to make sure it’s not biased? So it’s not a question.

    Well, it’s just questions we need to ask.

    bias is like any other any other professional vetting that you want to do in that there are things to look for, and things to request from a vendor in the same way that you would vet a vendor for equal opportunity, employment for non discrimination for fiduciary responsibility.

    There are so many different aspects to auditing and doing your due diligence on a company and checking for bias and artificial intelligence and machine learning models really shouldn’t be any different than checking to see if a vendor is You know, title seven compliant, right? If the vendor discriminates against people in hiring, you probably would want to do that.

    Know that, you know, when you look at any of these audit forms you’re required to fill out if you’ve ever been through a corporate audit or delightfully fun.

    But there are lots of questions about, you know, what’s your process around hiring, what’s your process around alignment to the Equal Opportunity Employment Act, all these different ways to look for problems.

    When it comes to bias in AI and dealing with vendors, it’s important to understand what kinds of bias to look for there’s six places you want to look for it and we’ve got other videos in the show.

    If you want to head over to the YouTube channel, you can see better definitions and stuff but the six areas we’ll bring this up here, the six areas where bias creeps in, in AI and machine learning are people strategy, data, algorithms, models and actions as So let’s talk about each one of these as it relates to a vendor.

    Number one people is easy.

    Who is has been hired? Right? Who are the people working on the models and algorithms? Who are the people building the software? If you look at the development team, or the engineering team, and you see a complete lack of diversity, there’s probably going to be a problem, right? Even if it’s not intentional, just having a monolithic view of the world, if it’s a bunch of, you know, say 20, mid 20s, Caucasian males, that’s your whole development team.

    They have a natural mindset that does not include people who are black because they’re not in their experience, right? It’s not saying that they’re, they’re bad people, just they simply do not have experience if none of them are female.

    They have no frame of reference for things that females people who identify as female might be interested in, right? So that’s an easy one.

    Look at the people look at the composition of the people.

    Look at the diversity of the people and if you don’t see any diversity, you know, there’s a problem.

    This, by the way applies not just to AI and machine learning, but to every vendor.

    If you’re hiring like a PR agency, go to that agency’s leadership team.

    If you see a whole bunch of people who look exactly the same, there’s a diversity problem there is, which means there’s a diversity of ideas problem.

    second strategy is where bias can creep in, what is this the the strategy that somebody’s going for? Really good example of this.

    Facebook has a strategy of engagement, right? They care about getting eyeballs stuck to their site, which means their algorithms tend to promote things that keep people engaged, like making people angry and afraid all the time.

    And so they’re, the outcomes from that strategy have been, as we’ve all seen, pretty substantially negative, right? We’ve seen a flourishing of hate groups and all these things because that’s the strategy did They intend to allow like Nazi groups to flourish? Probably not.

    But is a natural outcome of an incomplete strategy or strategy that was not informed by a diverse set of objectives.

    Yes.

    Third, data bias creeps in, in data.

    Where did the data come from? Right, where this is what’s called Data lineage or data provenance.

    How good is the data? Is the data itself balanced? Is it representative IBM has a fantastic toolkit called the IBM fairness 360 toolkit.

    If you’re fluent in Python, you can download this for free, run it on your data, declare any protected classes things like age, gender, veteran status, disability, sexual orientation, gender, identity, race, religion, and in your data, it will then say hey, this model does not look representative or this model has a lot of drift or this model is the state is likely to behave badly.

    So checking your data To the lineage of the data is important where the data come from.

    If your data came from sources that themselves are biased, that can be a big problem, for example, black American healthcare, all the data is wrong, right? Because of systemic racism, you cannot get really good large scale data on black American healthcare because there isn’t good data.

    systemic discrimination has created an entire pool of corrupted data.

    Number four algorithms.

    So the algorithms are the individual choices that you make, for what your models going to do, what strategy you’re going to pursue from an algorithm point of view.

    This is things like deciding if you’re going through a gradient boosting now or generalized linear regressions, all these different choices.

    Bias can creep in here because if you have somebody who doesn’t understand the full objectives and doesn’t have a background in diversity, they may choose a competition.

    efficient algorithm, but not necessarily one that is fair.

    So this would be a case for example of using something like a straight up a gradient boosting model versus something like Pareto multi objective optimization.

    The algorithms are very different.

    Pareto optimization allows you to essentially do what’s called trade off analytics, you will get a less well performing model but it it performs against, you know, many many different objectives as opposed to one objective kind of like what Facebook versus like LinkedIn how they function, they function very differently because of their optimization algorithms.

    Number five, the model itself the model can drift.

    The model when it takes in data as it takes in new data over time, it can drift the most famous example this is the Microsoft tape chat bot, which was corrupted by trolls basically, within 24 hours, it became a porn spewing neo nazi chatbot It was a train properly, but it drifted and drifted it didn’t have guardrails to keep it on the rails.

    So that’s a place where bias can creep in.

    And last is the actions.

    What do you do with the model? Right? What do you wear? What are you going to use this model for? This is a good example of this is a martech vendor I saw that was effectively reinvented redlining, right they they built a tool to identify ideal customers, and it reinvented redlining.

    And so bias crept in and in what their model was going, they’re going to do with the model.

    So that’s a very short period of time at all the places that bias can creep in, throughout the process.

    When you’re auditing vendors, when you’re doing your due diligence, ask them for their documentation about how they prevent bias in each of these areas, right.

    You would not get on a plane.

    If you walked in the cockpit and you saw there was no quick reference handbook.

    There was no preflight checklist and you know, the pilots are just kind of winging it right? They do not get on that plane.

    Because that is an unsafe play, and there’s no documentation, there’s no process, there’s no validation that things are working as they should be.

    The same is true with AI and bias, right? If a company has no documentation, no processes, no rigor, no checking for bias in each of these areas with real checklists, like real document checklists, here’s the bullet points that we look for at each stage of our projects, then there’s a good chance by scrapped in, and in turn, that means there’s a good chance that the what they produce is also biased too.

    So look for those ask for those as part of your process, and if they can’t produce it, probably a problem.

    Right? That’s the the easiest way to vet a vendor, ask them for the documentation called part of compliance or whatever.

    And the vendors themselves should recognize that if they don’t have this, they themselves are at legal risk, right because they can’t prove then they’re not biased.

    So, great question.

    We could spend a whole lot of time on this.

    Great question.

  • You Ask, I Answer: Difference Between Fair and Unfair Bias?

    You Ask, I Answer: Difference Between Fair and Unfair Bias?

    Gianna asks, “What’s the difference between fair and unfair bias? What’s the fine line?”

    Fair and unfair comes down to two simple things: laws and values. Statistical bias is when your sample deviates from the population you’re sampling from. Bias isn’t inherently bad unless it crosses one of those two lines.

    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, john asks, What’s the difference between fair and unfair bias? What’s the fine line? So fair and unfair bias really comes down to two simple things, two very straightforward things, laws and values.

    So before you deploy any kind of models, or build any kind of artificial intelligence systems, you need to understand what bias is.

    bias is when your sample your data, your whatever it is you’re working with, in some way statistically deviates from the population you’re sampling from.

    And bias doesn’t necessarily have to be good or bad.

    It just is.

    It’s a mathematical concept, at least in the context that we’re using it here there’s human bias, which is totally separate from statistical bias.

    For example, you may want to sell your product to people who have higher incomes.

    Right? That is allowed.

    Certainly, it makes logical sense.

    And income is one of those things that’s, you know, under somebody’s control to a degree whereas, say their race, they are not under any control of it, they have absolutely no choice in what race they are.

    They have no choice in what age they are, etc.

    So, when you’re talking about what’s fair and unfair, we’re talking about, are we building tools that disadvantage, a population on in some way that is either against the law or against our values, and the two may not necessarily always agree, there are plenty of things that you may decide as a company or as an individual, are unacceptable to your values, even if they are technically legal.

    Right.

    You may decide you don’t want to say include, gosh, firearms owners or coffee drinkers.

    From a, you know, doing business with you, and that’s totally fine because neither of those things are what’s called a protected class.

    protected classes are and this depends on where you live where you work where you do business, the laws change from principality.

    protected classes are attributes that are protected under law.

    In the United States, for example, age, gender, sexual identity or gender identity, sexual orientation, race, religion, religion, and credo are protected, veteran status, disability, these are all things that you may not discriminate on and have been held up in court.

    Any number of times to say these are not permissible things to discriminate on.

    And so when we talk about fair and unfair bias we are talking about does your software which is what an AI model is does your software in some way disadvantage.

    What people on one of these attributes, if your software says that, you know, we’re only going to show our products to white people, that would be illegal, that would be a, a, an unfair bias along a protected class.

    And again, you may have values that add additional things that you don’t want to discriminate on that you don’t want to advantage or disadvantage somebody on.

    Likewise, you bias is also something that where you advantage in one group of people over everybody else, so it doesn’t have to disadvantage one group, it can just it can disadvantage everybody except one group.

    So bias isn’t inherently bad unless it crosses the lines of laws and values.

    Now where this gets into trouble for AI and machine learning and data science is not necessarily in the protected classes, not even necessarily in the ethics and values, but in how machines use data.

    And, in particular, this is deals with correlates.

    So a Carla is when you have a variable or a group of variables that behave very similarly.

    So there is a strong correlate in, at least in America, for example, between income and race, there is the, the more of a certain race you are, the more probably your incomes higher or lower.

    And so if we’re building a machine learning model, say to only be able to demonstrate to show our ad or our system for our, you know, what we want for customers or who gets in line, who gets privilege treatment.

    And we’re doing it on income level, we are potentially also discriminating on a protected class, right? Because, again, there’s a strong correlation between race and income.

    So one of the biggest challenges that folks in the machine learning and AI space need to be addressing is doing things, you know, doing matching doing propensity scoring, doing regression analysis that demonstrates that the algorithm is discriminating on things that are permissible and is not discriminating on things that are not permissible.

    So, for example, if I’m selling high end coffee, right.

    And I want to discriminate on income level, which is permissible.

    I also have to be able to demonstrate through statistical testing, that, say, a black family with the same income level as a white family is just as likely to be shown our ad as the white family, right.

    Being able to say like race in this case is not a discriminating factor.

    Like if you are black and you have above a certain income level.

    You are just as eligible just to see our ads.

    If, but what will happen in a lot of cases is that people don’t do this testing.

    People don’t do this inspection of their own.

    And the outcomes, and they end up discriminating.

    And whether or not the intent was to discriminate does not matter, it’s whether you actually did.

    Because in a court of law, you will be held accountable for your actions.

    It’s like, you know, I didn’t mean to hit that guy with a hammer, I just hit them with a hammer really hard, I’ll know does doesn’t mean intent means nothing, you hit the guy with a hammer.

    The same thing is true here, where you may not have intended to discriminate along racial lines, or gender identity lines or veteran status, but you did, and you were liable for it.

    So a huge part of the work in AI and machine learning is to know to look for bias to test for it.

    And then to test for correlates to things that are not allowed things are out of alignment, the laws and values.

    And this requires money and time because these are expensive processes to go through and essentially deconstruct a machine learning model to understand how it’s making its decisions.

    And it requires a willingness to do so.

    Now, if the company you’re working for or the project you’re working on, the stakeholders say, No, we don’t want to do that, then at that point, you are personally liable for outcomes.

    Because at best point you may have said, I know there’s a potential problem, I know that we may be doing something wrong.

    If you don’t take action to correct it.

    You’re by definition an accomplice.

    So be aware of that.

    But a lot of what’s happening in machine learning really comes down to those correlates.

    And you just have to test for them you have to investigate, you have to know that there could be a problem.

    And that brings me to my last point.

    You have to be asking these questions of your models.

    Do not assume that the software knows to look for bias because most software out there a few notebooks options like IBM Watson Studio Studio do know to look for it.

    But most software doesn’t.

    Certainly anything you code yourself does not inherently do that unless you put it in.

    So you need to be building that in as a process in your systems so that you are looking for fairness, you’re looking for unfairness, you’re looking for discrimination from the get go.

    And that can happen in the data that can happen to the people you hire to work on the data.

    It can happen in the model.

    And it can happen in the model after deployment, where you get something called model drift where the model starts behaving in ways you didn’t intend it to.

    So looking for unfair bias isn’t something to do one time it is an ongoing process when you’re working with machine learning tools.

    So really good question.

    Where’s a lot to unpack here.

    There’s a lot to talk about when it comes to bias in machine learning, and AI, and in general, but these are things you must be aware of in order to reduce your risk to reduce your liability to reduce the likelihood that you get sued for You know, thousands or millions of dollars?

    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, Ashley asks, If you choose to use public datasets for your machine learning models, like from Amazon or Google, can you trust that those are free of bias? Hmm.

    Well, so there’s a couple different things here.

    companies like Amazon and Google don’t typically offer data sets.

    What they do offer are either models or API’s of some kinds.

    So Amazon, for example, has recognition and sage maker and all these things.

    These have API’s behind them.

    They have pre trained models.

    Google, many of the services in Google Cloud perform the same way.

    For example, Google speech to text, things like that.

    Google also does release actual models themselves, like the T five transformer library, which you can install into like Google colab or your local Python environment and use their pre trained models.

    And then there Yes, For example, Google datasets does offered raw data.

    Now, let’s talk about that.

    Can you trust that these are free of bias? In a word? No.

    In order you cannot blindly trust anyone’s machine learning models data is to be free of bias because you don’t know what’s in it.

    So as an analogy, suppose that you have a jar of jalapenos, right? A nutrition label that has five calories per serving.

    And what would I expect to see in this jar jalapenos, right as an ingredient and probably vinegar and water, right? Because that’s maybe some salt.

    That’s what’s in here.

    Can I trust that if I just look the label alone that that’s what I’m getting? Well, when I look at this, I go to jalapenos water vinegar, salt, dehydrated onions, dehydrated garlic, calcium chloride is a firming agent.

    sodium benzoate.

    is a preservative polysorbate 80 which is that in their tumeric for color, why is polysorbate 80 in here, you don’t need an emulsifier For, for peppers in a jar anyway.

    Can I trust? What’s on the label? Can I trust that what’s on the label is is accurate.

    For example, we had a dolloping, where they jalapenos grown, where they grown free of most no harmful pesticides.

    This case this jar is not labeled organic, so probably not.

    On the other hand, if you were in the EU and you had this exact same product, could you trust that it was free of pesticides? Yes, much more so because EU regulations for foods are much more stringent than the United States.

    The same analogy applies to machine learning and data science.

    What the model says is important but also what went into the model to make the model is just as important to be free of bias to be free of both kinds of bias both human and statistical.

    There are for example, any number of cases Is of bias that was unintentional.

    Somebody did not mean for the dataset to be biased or did not mean for their mouth to be biased, but it was because they didn’t do any due diligence when putting it together.

    Most probably famous case of this is Amazon when it attempted to build a hiring AI to screen resumes.

    They trained it.

    They weren’t looking for bias, and the model stopped hiring women.

    Right? Because nobody did any checks.

    So what’s the solution? Can you build from these systems and trust them? Well, there’s two different ways to handle this first.

    The first is to build your own model, which is expensive and time consuming, but it is the only guarantee that the data going into it is trustworthy because you will have vetted it and made it trustworthy and tested it.

    If you are somewhat familiar with Python.

    IBM has the fairness 360 toolkit which is a phenomenal toolkit, totally free, totally free to test datasets for bias.

    And if you are building your own model, you would use that to validate your data before the model is constructed.

    And then you can be reasonably sure that your model is free of at least of data going in being biased, you do still have to monitor it, you still do have to have for example, the protected classes that you’re monitoring for declared.

    And you still do have to ensure that the model when it’s running is not drifting out of the rails that you set for it the guardrails.

    For example, if you said that you know, gender must be 5050 split for 4040 1040 4020 then you would have to monitor and say okay, how far outside is acceptable, you know, is a 1% drift acceptable is a 5% drift is acceptable At what point To say, Hey, we need to either ran the model back and retrain it, or balance it in some way to get it back on the rails.

    So that’s one aspect is the, you have to build it yourself and train it and monitor it to is a risk judgment.

    Try trusting a model is proportional to the risk that you’re incurring with the model.

    So, if I am building a machine learning model to recognize sentiment in tweets, how vitally important is that going to be? No one’s probably going to die.

    If I’m using it for like social media engagement monitoring, probably nobody’s going to die.

    I might make some bad judgment calls, I could cause some damage to a brand.

    But for the most part, it’s not super serious.

    On the other hand, if I am producing, say, a new vaccine it had better be really, really, really biased It better be really representative had a better be really any model I built to try and assess the efficacy of something or identify a drug candidate had better be pristine and it’s freedom from bias because it could actually kill people right the risk level is substantially higher.

    So, the the standards that we must hold that model to are much more stringent facial recognition for say like at a tradeshow booth, relatively low risk, right if you miss identify somebody for you know, as as a gimmick to attract people to your tradeshow booth, not huge facial identification being misused by police, big deal, a life threatening deal.

    So you had You’d better make sure that that model is properly trained and unbiased.

    So that’s how to evaluate you know a lot of these models and data sets and pre trained models and API’s from major vendors.

    Is was level of risk and what is or consequences if it gets it wrong.

    Bear in mind that an awful lot of machine learning models are biased especially in facial recognition.

    And in natural language processing.

    Natural Language Processing has a lot of hidden biases, the most obvious one of which is most of them are trained on the English language and English is, I forget who said it is a language of privilege.

    It is the language of the wealthier part of the world.

    It is not the majority language in the world.

    And there are many, many, many, many billions of people who speak other languages.

    And many of our machine learning models are not well suited to recognizing or processing those models.

    And if you think some of the things that AI does with English are hilarious, you should see what they do to other languages.

    When you give that some consideration and who speaks English and what race they are, and what gender they are, and what income level they are, what ethnicity they are, what religion they are.

    You can see how even something as simple as using the English language could introduce biases into your models.

    So keep that in mind.

    It’s all about trust and risk.

    How much trust Do you need in the model? How high is the risk, and that dictates whether you should be training your own versus using a third parties.

    You Ask, I Answer: Most Common Biases in Marketing AI?

    Elizabeth asks, “What’s the most common type of bias you see that we as marketers should be aware of?”

    There are so many to choose from, but I’ll start with two: confirmation bias, and selection bias. Confirmation bias corrupts the entire process by looking for a result that fits a predetermined conclusion. Selection bias corrupts the entire process by failing to represent the population you’ve said you’re studying. Watch the video for more details.

    In today’s episode, Elizabeth asks, What’s the most common type of bias that you see that we as marketers should be aware of? Gosh, there’s so many to choose from.

    Um I’ll start with two of these.

    Because these are the two that again, are probably the most common and things that people don’t think about.

    The first is confirmation bias.

    So confirmation bias, pretty simply is when you start any kind of data science or AI project with a intending to look for a result that fits a predetermined conclusion.

    And you see this a ton in research studies especially.

    But obviously it can extend to building models which are nothing but software based on data is simple.

    Example this, let’s say you’re a SaaS based company, right? And you sell, I don’t know, photo editing services, make something up.

    And you want to promote your services.

    So you build a predictive model that has the marketing goal of telling people, they should edit their photos more.

    Right? You do some market research and all this stuff.

    And of course, you come up with a conclusion that yes, people should edit their photos, a lot more mail, better edited photos, perform better on social media, and you create an algorithm that predicts If only you had edited this photo, it would have earned this much more engagement.

    Now.

    That’s kind of a silly example.

    But you can see how that particular bias corrupts everything.

    Because you are working towards a predetermined conclusion rather than building a model that is truly open to being asked.

    trained and can yield results that frankly might not support your business.

    Right? Again, you see this most often in research.

    There used to be a company not too far from here in the Boston area that would sell this as a service.

    They were, they were sort of the antithesis of good research.

    Yeah.

    They say, hey, you want to prove whatever thing you know, hire our services, we’ll come up with a statistically validated way that proves your thing.

    And anytime, you know, once, once that was known, anytime you saw that company’s name in the in the methodology, if it was even listed, you know, yep, that survey is completely invalid.

    You know, that they, the company that sponsored it bought the result that they wanted, and it ruined the research company’s credibility, and it ruins the credibility of any company that uses that research company.

    So that’s probably the first one that one is relatively easy to spot inside your own organization because your VP of marketing or CEO or somebody says, Hey, I need something that does this.

    That’s not how research works.

    That’s not how good models work either.

    Because one of the things that will happen is that if you are willing to tolerate bias, like that conscious bias in your model, and you are willing to tolerate biases that are discriminatory, that’s going to get your butt kicked over time.

    Second, is selection bias.

    And this corrupts the process because it is a bias that exists your data set that does not represent the population as a whole.

    And so you’re using data that is inherently skewed in some way, consciously or unconsciously.

    And it does not represent whatever population you’re trying to serve.

    So simple example number of years ago Hubspot did a research study saying, you know, we, they made some claims about inbound marketing, which is their thing.

    And when you look at the methodology that says we emailed it was a survey and we emailed our list of you know, however many people we can see the problem here.

    You can’t make a survey that claims to represent all marketers based on your own email list.

    Because people who are on your email list inherently have a greater affinity towards your products and services.

    Right HubSpot was all about and still is about inbound marketing.

    Naturally, somebody who subscribed to their email list probably has at least some passing interest in inbound marketing.

    And as a result, you have a survey that is biased towards people who like inbound marketing and so to make a claim that this represents all views of all marketers is incorrect because there’s this whole group of people out there, not on their email list who probably don’t give too much.

    Have a have a fish at non animal market, they don’t care.

    They don’t it’s not their thing.

    And so their views are not being represented in the survey methodology because it was it was they were selected out.

    Right.

    They were not part of that population.

    Now.

    What could that have certainly have represented.

    You could have certainly said all marketers who are in the HubSpot audience, believe this and that would be valid.

    Right? When you’re collecting data for data science and AI projects, the same thing applies if you are collecting data from a specific focus group that you selected.

    Did you select a group that was representative of your audience as a whole and b2c? That means balancing against things like age, gender, physical location where that person is other demographics.

    This is one of those rare cases where you should be using protected classes like race Gender Identity etc to make sure that you are balanced against the actual population that you don’t have a non representative sample on b2b.

    You’d be looking at things like a balance of companies by size by revenue, number of employees.

    industry, and it should look like the the balance of as a whole.

    So if you do a survey, and your initial data pool comes from 61% technology companies come technology companies just make up 61% of the global economy or even one country’s economy.

    They represent, you know, typically a much lower slice, depending on the metric you choose on.

    So you would want to be sure that you are balancing your dataset to represent the population that you’re claiming to study.

    And selection bias tends to selection bias is not As intentional as confirmation bias confirmation biases, I want to put my thumb on the scale.

    And I want it to say this, which is just a horrendous thing to do.

    selection bias happens more often than not because of naivety, a naive researcher or marketer, or data scientist will just do something and not think, am I balanced? And that’s something that you can solve with things like checklists like did you balance this dataset? Did you balance the input collection methods? Are you Are you truly representative? Have you checked? Have you validated that your data is representative? If you can solve for both of these biases, your data will inherently across the spectrum of the ways that use data from market research data science and analysis projects to AI models will inherently get better.

    It may not deliver the results you’re expecting.

    Particularly if you have a preordained conclusion in mind.

    Even if you keep your processes clean.

    But it will be better.

    It’ll be objectively better data.

    And if you’re using that data to make decisions which you should be, you will make better decisions.

    So really good question.

    There’s a whole bunch of other biases.

    And there’s, there’s a difference between a statistical bias and a human bias that we’ll leave for another time.

    But these are the, I would say the two most common statistical biases that we see in data science and AI, you know, follow up questions, leave in the comments box below.

  • You Ask, I Answer: Data Democratization and AI?

    You Ask, I Answer: Data Democratization and AI?

    Jim asks, “I am skeptical of data democratization because the average decision maker does not understand data collection, transformation, integration etc. Doesn’t AI make this an even bigger problem?”

    It depends on how abstracted the decision-maker is. Certainly the pandemic has shown us the general population is completely incapable of parsing even basic scientific data, like why you should wear a mask. So the question is, who’s working on the AI?

    If AI systems are left in the hands of legitimate experts, it could potentially improve things. For example, IBM Watson Studio has bias detection built in at multiple levels, so the tooling can potentially improve our work – or at least make it easier to audit. On the other hand, if you have the 6-week crash course folks building models, then yes, it could make things much worse.

    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, Jim asks, I am skeptical of data democratization because the average decision maker does not understand data collection, transformation, integration, etc.

    Doesn’t AI make this an even bigger problem? So, let’s first quickly define data.

    democratization is the ability for anybody to be able to work with data hence the term democratization.

    Just like new media, a podcasting and blogging was the democratization of media the ability for anybody to make a podcast anybody to make a blog as such.

    And data democratization has been something that has been on technology companies radar for a really long time.

    My my whole start working with IBM, years ago, was around Watson Analytics, the idea of the citizen analysts as the average person who could pick up some good tooling data set and generate some usable insights didn’t work out so well.

    And to Jim’s point, the reason it didn’t work out so well is because data analysis even though it sounds simple, isn’t there are a lot of pitfalls.

    There are a lot of gotchas.

    There are a lot of things that are not taught well and poorly emphasized when people start working with data things like margins of error and statistical relevance, statistical validity.

    All these things are things that in a laypersons experimentation with with data and math and, and statistics and such, don’t really get covered.

    People have a tendency to approach things in a very naive fashion which is normal.

    And they pick up a tool they run a basic analysis they haha I’ve got the answer.

    You can You can tell how expert somebody is in the realms of mathematics and statistics by how many shades of grey? their answers come with, right? The beginning person is like, this is the answer.

    You know, the extra person is like, well, there’s a whole bunch of reasons why this may or may not be the answer.

    And we’re not really sure.

    We can give you probabilities, we can give you a sense of reliability or not in the data, but for the most part, it’s not as cut and dried as you think.

    Right.

    And those are the answers people hate.

    People hate those answers.

    And that’s why data democratization hasn’t worked out so well, because there are a whole bunch of people who want the answer.

    And the answer doesn’t exist, there could be a range of answers.

    So does AI make this worse? Well, it depends on how abstracted the decision maker or the the AI tool user is from the tools themselves.

    Certainly, the pandemic In particular, has shown us that the general population is completely incapable of parsing even basic scientific data like why to wear a mask? Sorry.

    It’s true.

    People couldn’t get understand even the most basic scientific facts and data points and make good decisions from them.

    So the question then is, does AI make this worse or an even bigger problem? It depends on who’s working on the AI.

    It depends on who’s working on the models.

    If you hand somebody a piece of fully polished software, a model of some kind of, they can’t really tinker with the innards.

    They can only use it for its intended purpose.

    The likelihood that it goes off the rails is lower.

    If it’s good software than somebody say, picking up Python and just trying to hand it copying and pasting the code randomly from Stack Exchange.

    If AI is left in the hands of legitimate experts, it could potentially improve things IBM Watson Studio is introducing bias detection at multiple levels in the process from data intake, to model to model drift, right? And it puts a big old warning saying like, Hey, your models drifted more than 6%, or Hey, your models drifting on this protected class, I should probably not do that.

    And so in those instances where the the, the person who’s working on the system has to stay within the boundaries of a well trained system and has to obey the warnings that it gives, yes, ai could potentially improve our work and potentially reduce some of the problems that come with data democratization.

    On the other hand, if you get that, you know, six week Crash Course a person who, you know, took the six week crash course in AI certificate.

    Yeah, I could make things a lot worse because that person doesn’t have the background in data science doesn’t have the background in stats and probability.

    Probably It is a generalization, but probably doesn’t have that level of background and that level of experience of just having models go off the rails.

    And without a mentor without somebody more experienced to guide them, it could make things a lot worse I was having a conversation with a of a founder of a startup a few weeks ago, was talking about how there’s got all these sophisticated models are working on building and you know, you had a friend of his from college, they just both graduate from college, you know, they’re gonna engineering these models and have some experience in it.

    And I said, Okay, tell me about how you’re doing bias detection.

    Tell me about who on the team has the most experience with ethics and data ethics and he’s like, a, like, Okay, so this is gonna go off the rails pretty quick.

    I said that you need to be building into your product.

    Things like monitoring for model drift.

    Things like looking for ethical problems, things like that would you know, fail you on a basic ethics audit.

    This was news to the person.

    So in that instance, where you have a bunch of people who are inexperienced with AI, trying to deploy it, yes, AI is going to make those problems of data democratization even worse, because these are people who don’t know what they’re doing.

    On the other hand, you get somebody who has, you know, 510 15 years of experience.

    In working with datasets, knowing when a data set is imbalanced knowing when a p value has gone off the rails knowing how to do a two tailed t test.

    In those cases, the person who’s building the system will probably do okay, and will make a system that is hard for other people to screw up.

    So it really comes down to which is going to deliver a good outcome a good long term outcome.

    One of the dangers In AI, particularly round bias is that a system with no constraints will perform better, it will do things that you do not want it doing well.

    It’ll behave in unethical ways.

    But it will, in the short term deliver better results.

    a longer term assistant built for the long term will make trade offs and say like, yeah, we don’t want bias on gender identity, we don’t want bias on race.

    And the system will have to sacrifice some levels of performance, the model’s ability to generate the top nine performance in order to meet those competing objectives.

    But that’s exactly the kind of caution and care and attention to detail that you want.

    So will AI make data democratization worse, potentially? Will it make it better potentially all depends on who’s steering the ship? How do we help people steer the ship better? give them that list of questions the pickup Dr.

    Hilary Mason’s free book Ethics and data science has got a ton of great checklists in it about questions you should ask before starting any project with data, ethical questions, process questions, accountability questions, those will help make all of us better data scientists, better data analysts better AI engineers.

    And if you work in a company and you have a leadership role, hold your company accountable to a lot of those those benchmarks, say we’re going to adhere to these basic processes, so that we generate outcomes that will not get a sued, or get us failing an audit of some kind.

    So, really good question.

    We could spend a lot of time on this.

    You Ask, I Answer: Determining Facebook Ads Effectiveness?

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

    You’ll need to do a content assessment in 4 layers:
    – Audience content
    – Your own content
    – Competitive content
    – Landscape content

    Once you’ve done all 4, you’ll have an understanding of what the different concepts and media types are that resonate with your target audience and can determine the ad format and content.

    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, Jen asks, How can brands find out which kind of Facebook ads work best for them? So this is a important question for not just Facebook ads, but any kind of ad.

    The advantage of Facebook is that it’s a closed ecosystem so that you can do apples to apples comparison of the different types of content.

    The starting point for this is content analysis is understanding what resonates with audiences.

    So you’re going to need to brush up on your Facebook data analysis skills, and getting data out of Facebook so that you can analyze it.

    There’s four different buckets of content that you need to understand.

    The first is audience content themselves.

    If you have a list of people that are customers at face, customers are your company on Facebook, looking at at their stuff, what do they share? What do you They post What do they talk about? And this can be qualitative.

    This does not have this step does not have to be strictly quantitative.

    It’s just trying to get an understanding of what stuff.

    Do people find compelling? What stuff? Do they post on Facebook? What are the things that they share? And then we share and comment on.

    Getting that sense of who the audience is, is really important.

    And you can also get some of this information, not all of it, but some of it from Facebook Audience Insights, if you have a page, and that page has at least 1000 likes, then you can start to really dig into the data and understand what are the aspects of the audience that are important, what other pages Do they like? What were their demographics, things like that.

    If you have access to Facebook data tools like Facebook, Audience Insights, Facebook, CrowdTangle, etc.

    You can pull a lot of this data and start doing it.

    Very large scale topic modeling to understand.

    For example, if your audience in Facebook Audience Insights your audiences there, you can look at the top 50 pages that that audience also likes, and examine, again, examine their content.

    Second step is you have to understand your own content.

    So again, this is this is going into Facebook analytics, and doing an analysis of the stuff that you’ve posted, what content has gotten an engagement, what content has got has performed? Well, understanding that is critical for your ad content.

    Because what you don’t want to do is just kind of create ads randomly.

    You want to create ads on things, topics, concepts, ideas, that have already done well for you for your Facebook page.

    If you haven’t done that, if you have no content that resonates Well, well.

    Facebook might not be the place for you then.

    If you’re posting and posting, posting, just getting nothing Maybe do a week of boosting posts just to see if anything resonates with your audience you might have to pay to play just to even be seen, and then make some judgments based on that.

    The third data segment you need is competitive content.

    So what are your competitors sharing? What are your competitors? What ads your competitors running? And what kind of engagement do they get on them? This would be direct competitors.

    And again, you want to see what’s popular.

    The fourth bucket is what I call landscape content.

    This is looking at companies that are functionally similar to yours, but are not competitive.

    So let’s say you own a Chinese food restaurant that delivers you, you might look at other Chinese food restaurants, you might look at other pizza restaurants, restaurants that deliver in general, you might look at instacart you might look at the coffee shop You might look at Whole Foods, basically, for people who get consumer items delivered to their house, what content is engaging with them? Are there things that are relevant to the product or service that is being shared in this landscape of behaviors? If you’re a b2b company and you sell SaaS based accounting software, what do other SaaS companies not in accounting software doing? What is working for them was like SAS based email marketing, software marketing automation software.

    Again, we’re not necessarily looking for the exact topic for those non competitive but similarly structured companies.

    What we’re looking for is audience behavior of a group of people who are receptive to the type of service that you offer, and then trying to figure out what resonates with those people.

    Once you’ve done all four analyses, you have a you should have an idea of the different concepts different media types, different topics that your audience is interested in.

    I would also suggest using a social listening tool, some guidelines, we used Talkwalker for all of our stuff.

    And again, getting a sense of those topics and keywords and related conversational things in order to understand your audience better.

    Once you’ve got all that down, then you can start creating ads, you should be able to see if in your Facebook data that videos about cats always seem to do well or videos.

    Behind the scenes videos always seem to do well.

    Even if they’re not yours.

    Even they’re competitive.

    That should give you a sense of Okay, if we’re going to run ads on a video, the video that we run ads on or the video that we put in our ads should be behind the scenes or maybe you know behind the scenes video with cats in it right.

    If content that talks about How your product works has resonated well with your audience.

    Try running some ads on that as well.

    The key is to try and align your ads as best as possible with what the audience already likes.

    Because with Facebook, you don’t get many shots at engagement, right? The algorithm works in such a way that content that gets engaged with does better content that doesn’t get engaged with get does worse.

    And it becomes very much kind of as virtuous or vicious circle of feedback, where things simply you get less and less engagement, which means you get shown less, which means you get even less engagement.

    And obviously, the only way out of the vicious cycle is to pay your way back to getting some eyeballs.

    That’s why the competitive analysis and the landscape analysis is so important because your own data may say, hey, nothing’s working.

    And if that’s the case, you need to look at other data sources to calibrate your ads on so that’s it How you can find out what kinds of ads work best for you.

    I would strongly encourage, as you do that, to test to test a lot of different stuff, if you have the budget to do so, test a lot of stuff to see what different types of content are.

    So when you do this analysis, we have four or five or six major topics.

    If you got the budget run, you know, two to three ads in each topic and see again, which one resonates the best, which one gets people to engage even with the ad itself.

    If after all this, you still not getting ad performance, it’s probably because Facebook isn’t the place for you, for your audience, even if they’re there, they may not want to engage with your kind of business on Facebook because that’s not why they’re on Facebook.

    They’re on Facebook to stay in touch with friends, to complain about politics, you know, all the things that we usually use Facebook for And so doing business with you may not that may not be the place you may be better off on a LinkedIn or Twitter or YouTube, or even an email newsletter, right? So do the analysis.

    But understand that Facebook may not be the place for you.

    The easiest way to make that determination is check how much unpaid traffic you’re already getting from Facebook.

    If it’s zero, or very close to zero, or you know less than 1% of your site’s traffic.

    Facebook might not be the place run some tests to verify it, run some ads to test that assumption.

    And if the ads don’t perform, you know, it’s not it’s not the place for your audience.

  • 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.

    Stephanie asks, “How can marketers measure if their content is improving the customer experience?”

    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 can marketers measure if their content is improving the customer experience? So really good question.

    When it comes to the customer experience, we have to remember that the customer experience is divided into fundamentally two parts.

    There’s the buyers journey, which is the experience the person has up until the point of purchase.

    And then there’s the owners journey, which is the, the experience you have after ownership.

    And each half of the customer’s journey has four stages to it.

    You can make an arbitrary and divide them in more granularly if you want, but the generally accepted at least by like all the big consulting firms is that there’s going to be for three or four stages in each.

    On the buyers journey side.

    That’s awareness, consideration, evaluation and purchase.

    So awareness is do I even know what the thing is considered? is a big vendor set evaluation is you know, winnowing that down to a choice and then purchases the actual making the decision on the owners journey side there is ownership, satisfaction, retention, loyalty and evangelism.

    And each of these stages has behaviors that you would expect a person to be doing so for example, in the loyalty phase and of the owners journey, is this person buying add ons? Are you able to upsell them? Are they engaging with your content, your your marketing on the evangelism phase a very important one are people really sharing and recommending your stuff even if they’re already customers? This is especially true important for businesses where there isn’t a lot of repeat business.

    Example real estate, when you buy a house, you won’t buy another house and you know if days, right? You will buy a house and weigh three to seven years.

    So that relationship and that loyalty and that evangelism is so important to the real estate industry to be able to say to somebody, you know, who’s asking, Hey, I’m thinking of selling my house, who should I talk to, and you come up with a name that you want to recommend a person to as as an agent.

    That’s the important part of the owners journey.

    So when it comes to measuring the content throughout the customer experience, there’s two different ways to do it.

    In the buyers journey portion, there is the ability to look at the content you’re creating, and see how it accelerates pipe the pipeline.

    There’s a bunch of different ways that you can do this.

    The way that I like best is using what’s called Markov chain modeling is a machine learning technique.

    In fact, I’ll bring this up here.

    And what you’re seeing here is a model from my website, my personal website for the month of August and what pages accelerated somebody towards a conversion like they were on this page and this page played a part in their path to conversion.

    The way the mathematical technique works behind this is that it’s like the old archetype, archetypical story of a college that didn’t pave any sidewalks then they let students walk around on campus for a year, and then paved over where students walked the most.

    If you can imagine something on your website, where what is the content that people walk over the most on the way to conversion in this case, is a few blog posts in here, there’s a few landing pages in here.

    And these are the pages that are helping nudge people towards conversion, this may not be the last page that they visited, but this is one of these are the key pages that people visited in their path to conversion.

    And so we will use this analysis to determine Yeah, is this page is this content, helping improve the customer experience on the buyers journey? The answer Yes, the fact that the number one piece of content there is a blog post tells me that blog post needs to be constantly optimized and improved, so that it continues to help convert people.

    So it continues to help push people forward.

    Now, on the other side of the coin is the owner’s journey.

    And you could do similar things like this.

    restricted if you have the data and user ID turned on in Google Analytics to just people who are already customers.

    But it’s probably easier to use either your marketing automation software or your CRM software.

    Most good Modern Marketing automation software tells you what pages people visit on a website.

    And so for the people who have converted who who are customers, you absolutely should be tracking the same information.

    What are the pieces of content that customers engage with that help them remain loyal, that helped them evangelize if you’re depending on how good your marketing automation software is, you made Be able to determine that piece of content to something that customer is sharing with others.

    And that is a lot of value in that and that information knowing that this is the content that customers find valuable.

    With your marketing, if you’re following customer centric marketing, meaning that you’re trying to help people solve their problems, the best content you have, should be almost equally applicable to a prospect as to an existing customer.

    If you sell coffee, and you’ve got you’re in the middle of a pandemic, maybe you’re not fully open.

    You can absolutely be sharing content like how to prepare the perfect cup of coffee at home, how to store your coffee beans at home safely, and in doing so you’re helping obviously prospects, you’re demonstrating your expertise, but you’re also helping existing customers, customers who have bought your stuff and you want to help them get more out of it.

    Their purchase.

    And so you can solve the problem for both audiences and create content that’s valuable to both of them.

    But the measurement part is the key.

    Depending on your marketing automation system, and how easy it is to export data out of it, you may be able to even construct a similar kind of model.

    You just have to figure out what the objective is that you’re tuning in for.

    At the very least, you should be able to export all the URLs of all the content that your marketing automation system is tracking, this is in the owners journey.

    And just do a quick tally month over a month.

    What are the what are the pieces of content that customers go to visit more often? And that will help you match it up.

    Now, where there’s going to be interesting value is when you compare the two data sets you say okay, what are the prospects like what a customer is like, how much overlap is there? If there is very little or no overlap in these two datasets? That tells you that you have content serving very different audiences and you may Want to think about is there a point where there should be more intersection? And if so, that may be a blind spot in your content marketing you can feel.

    On the other hand, if they are completely converged, you may have opportunities at the edges of each section of the customer journey, that you’re not fully fulfilling, right? You’re not you don’t have enough content maybe on the far and the awareness side of the customer experience in the beginning of the buyers journey, or you may not have enough content that is suited for evangelism that people are sharing that people want to be sharing.

    So you use this data to help identify gaps in your content marketing for improving the customer experience.

    But that’s the measurement system that I would recommend is using a marketing automation software data using Google Analytics data to fill in the blanks for both sides of the customer experience and delivering a better overall customer experience with improved content marketing.

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

    In this episode Brianne asks, What habits do you do on a regular basis that help you learn and stay ahead in the AI and Mar tech space? So it’s a good question.

    Any kind of progress requires you to be doing two things to build a third thing.

    And those two things are you need to be learning, which is the academic knowledge act, acquiring information, processing and understanding what it is that you’re reading.

    And then two is practice.

    implementing what all the things you’re reading so that it’s not just theory.

    You understand how it works, make your own discoveries, and more importantly, discover what doesn’t work.

    Those two things combined get you experience or wisdom if you’d like.

    And they are required in equal amounts.

    One of the challenges we see happen a lot is people who are over leveraged in one of those two areas, they are spending so much time doing the thing, that the knowledge gets stale.

    I meet a lot of practitioners at corporations who are so heads down on getting the job done getting that to do lists cleared and stuff that they lose track of what’s happening in industry, they don’t know that, you know, this new model came out or this new technique is available, or this new software has happened.

    Because it’s just one of those things.

    They’re trying to stay afloat, which I totally get.

    I had experiences like that and agency life where you’re working 60 7080 hours a week, just to get things done just to keep things moving along.

    The academic knowledge without practice, is armchair theory, right.

    You can read about something go well, it could do all these things.

    But you never actually understand how the work so you don’t understand the limitations.

    And you may not even understand what it is you’re talking about.

    When I was in graduate school, I remember this one class where the professor was talking about OLAP cubes, online AP application processing, take notes on it, the type of database.

    And he was talking about the theory of OLAP cubes and transaction processing, and had never actually used the technology.

    So in class one day, I said, Okay, well, let’s just set one up, because at the time, Microsoft SQL Server supported that.

    I said, let’s just set one up.

    And we did.

    And it turns out that most of this professional theories about how OLAP cubes worked, didn’t hold up because the practical application was very, very different.

    And he really was not aware of that.

    Now.

    In fairness, It wasn’t necessary for his job to do that.

    And the theories themselves, I think were starting points for people to try to figure out how to implement them.

    But that’s why you need that practical application and the academic theory in tandem, they can’t have one without the other.

    And so for what I do, to stay current is those two things on the academic theory side, I put together newsletters, I read a ton.

    In order to do that.

    I have software that helps curate a list of the top things I need to pay attention to in martagon, marketing data science and AI.

    And as I’m putting together these newsletters, I’m reading through what the machines have have assembled as my reading list.

    I go Wow, I didn’t know that happened or I didn’t realize that happened or this was the thing.

    That’s like 1500 articles a week and just going through this.

    Wow.

    There’s a lot That’s happening that was not aware of and as I go through and put together my newsletter, I go that’s useful that’s useful that’s useful.

    Go and read those things.

    I also belong to a number of communities I run a slack community as part of Trust Insights.

    If you go to Trust insights.ai slash analytics for marketers, that’s the community I run but I’m also in two dozen other slack communities about half a dozen discord communities.

    I’m subscribed to I can’t tell you how many newsletters voluntarily that all bring in new information, new academic information to learn Hey, did you know this thing was happening? I was reading Elisa Solis is Seo FOMO newsletter the other day and this is how core web vitals are going to be part of ranking download, okay, I need to know that.

    But then the other side, the practice side is doing the thing.

    Now, a lot of I get a lot of practice doing stuff for, you know, clients at Trust Insights and things, but I also So you’ll run my own website, my personal website now Christopher Penn calm, I test a lot of things out on it.

    Because it’s a safe place to test.

    I’m not going to destroy my company’s revenues to fight to take down a website by for an hour by accident.

    I do.

    I’ll just a lot of testing in general, I used to do a live stream show called Saturday night data Party, which was more just messing around with stuff, playing with things.

    As new models come out, or as new pieces of software come out if I can run them in an environment like Google Collaboratory run in there, see what happens.

    I’m actually got another window open over here, trying to run a model called jukebox, which is going to do generative music creation, which is interesting stuff.

    So it’s just picking up things as you read about them saying, I’m going to try this.

    How does this work? What does it involve? And can I make the thing work and generate the result that’s promised result and you find out really quickly Some things live up to their promises, other things, not so much on a good day, you might be able to get them to work on a bad day.

    Just immediate and hilarious failure.

    So that’s the process.

    The challenge is, you have to build time and your schedule for it, you have to make time for professional development.

    It will, in almost every place I’ve worked, there’s been a lot of lip service to professional development and like maybe an organizational send it to a conference like once a year.

    But that’s it, they will not create the time for you.

    So you have to do that.

    And if you can do that in your working hours, great.

    Sometimes you have to do it outside your working hours.

    If you care about your professional development, you will have to make that time outside of work.

    You’ll have to take time away from something else like you know, whatever series you’ve been doing on Netflix, in order to give yourself time to research and grow and that’s the hardest part for you.

    But people are not willing to make the time for themselves personally, even if it’s a benefit to them professionally and to their careers and to their their income, all that stuff.

    I don’t know why doing stuff that is for professional development has just been something I’ve always been part of doing.

    I think it comes from either whether whether you like the process of learning or you don’t.

    But I think is a learnable thing.

    I don’t think it’s something you’re born with.

    It’s just overcoming perhaps bad experiences in the past.

    So that’s the process, academic knowledge, practical application, put the two together to get experience and make the time for it.

    Make the time for it.

    Dedicate two hours a week, wherever you can find them.

    To do that one hour reading one hour of doing your follow up questions, leave in the comments box below.

    You Ask, I Answer: How Often Should Ads Be Changed?

    Jen asks, “How often do you feel like ads should be changed out and freshened up?”

    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, Jen asks, How often do you feel like ads should be changed out and freshened up? Well, I don’t feel anything.

    General.

    I mean, when it comes to decisions like this about your marketing, you shouldn’t be relying on your feelings.

    Because your feelings, frankly, are a little on the bias side, you may have seen the same ad over and over again.

    Or you may be looking at the same website design over and over again and you get tired of it, but you are not your audience.

    And that’s an important part to remember here is you are not your audience.

    What you do in your marketing, probably, unless you’re very much in the market for what your company sells, and not the customer.

    And so your feelings about things like advertising really should be put to the side and focus on the data.

    The data will tell you what’s going on whether your ads are working, whether your ads or not.

    Working.

    And for this particular question, there is a very specific technique that I recommend, that can help you make the determination about when it’s time for a change.

    The technique name is something called a moving average change indicator.

    And it is exactly what it sounds like, tells you if something’s changing when you look at your moving averages.

    So let’s look at a practical example of this.

    We’re gonna flip this around here.

    What I have here is basic ad data, right? You have the date of the ads, and you have the ad performance, could be clicks, could be conversions could be any number you want.

    And this is important point.

    When you’re looking at something like this, this can apply to pretty much any kind of marketing data, Facebook ads, Google ads, email marketing, you know, list performance, it can look at website traffic, whatever it is, it can help you understand sort of the diminishing returns.

    So the first thing you want to do when you’re looking at any kind of data set like this is just to get a sense of What is the data tell us? I want to do a very quick chart here.

    Now we’re using Google Sheets.

    But obviously you can use the the tool of your choice.

    And already we can see without doing any substantial analysis that there is a general down into the right line, right, we can tell that things are not going well.

    Now, here’s the catch.

    When it comes to ads, this particular look is fine and retrospective.

    But if you started your ads at the beginning of the month, wouldn’t it have been nice to know that like ads performance was not great, before we got to the end of the month and spent all that money and didn’t get the results? So how do we do this? We’re going to do what’s called again, a moving average change indicator.

    So let’s make a new column here called moving average.

    And a moving average is nothing more than exactly what it sounds like.

    It’s a window of time.

    Let’s do this.

    We take the average of the previous seven days.

    And why is this important? Well, as you just saw from the chart earlier, there’s a lot of ups and downs in this overall series.

    So let’s go ahead and chart this now.

    And you can see, but by using a moving average, we smooth out a lot of those ups and downs, and get a much closer look at what’s actually happening with a seven day lag.

    And again, you can choose any window you like, I typically like seven days, because for a lot of businesses, and in my business, in particular, Trust Insights.

    We’re a b2b company.

    And so weekends will always throw off a shorter window moving average in seven days, just because people do less stuff on the weekends.

    So here we see the moving average, and it’s changed over time.

    Now, what we really want to do is next, we’re going to create a moving average change indicator.

    And this one’s a real simple calculation.

    It’s actually the same formula as our Hawai new minus old divided by old.

    So in this case, we’re going to take the new, which is the second in the series minus the old, which is the first in the series, divided by the old.

    And drag that down.

    And now let’s go ahead and get rid of this and just chart these two columns.

    What we see here is the zero line, which tells us when our change, our rate of change has gone into negative territory.

    And then everything below this.

    Now, what does this tell us? What is it telling us? Well, it’s telling us that the moment our indicator goes below zero in this thing, it means our ads have really stopped being effective, and the longer it stays under zero, the worst performances or the worst performance has gotten by having this indicator in place.

    You You could have you could be monitoring for, you know, changes in your ad performance and know that, yeah, you hit diminishing returns, you hit diminishing returns pretty early on actually.

    And in this analysis, then you can see there’s not a whole lot that’s going on that’s, that’s good.

    This is how you tell that you hit diminishing returns.

    Once this indicator goes below zero, and it stays there for maybe two or three days, it’s time to change reds and freshen them up.

    Ideally, what you’re doing is you’re doing this sort of computation, a calculation on a bunch of different ads, and that as an individual ad drops below this line, and you say, Okay, it’s time to retire you It’s time to try you, you’re still going well, you’re still going well, you’re still showing growth, but and and so on and so forth.

    And you can cherry pick the the ads that are just have run their course they’re there, they’re out and done.

    Now, how do you implement this, practically if you’d have no other technical capability And then maybe you download your ads data, once a week, say Friday afternoons and you do exactly what we did here and just run those computations.

    And then you change up the ads and freshen them up and get them ready to go for Monday morning, if you don’t run them on the weekends, or if you do, depending on your business cycle, change the ads out whenever your slowest a typically is.

    If you have more technical capabilities, what we just did is relatively straightforward to put into a piece of software that you write something like in Python or R, that can connect to your different ad systems, download that data, and then run those computations.

    That’s a more sophisticated way of doing this maybe even sends you an email saying like, hey, ad 23 has hit diminishing returns, it’s time to retire.

    That would be the the ideal solution.

    So you don’t have to manually do this every Friday afternoon.

    And it just alerts you Hey, something’s going on with this ad.

    This ads just lost steam.

    And likewise, you could even configure it to say like, hey, this ad Picking up on usually maybe add some more budget to it, maybe do something else that is a, you know, can reinforce, maybe make some copies of interesting variations, you would think that ad systems would have this technology built in, but they, they don’t really, I can’t think of any vendor that includes this level of analysis.

    And so it’s really important to be doing it on your own.

    However you need to whether it’s manually or with, it’s a more sophisticated way of doing it.

    But this will get you improve return on investment of ads substantially over time, because, again, once it adds run its course you take it down.

    And more importantly, to the original question, just because you’re tired of it doesn’t mean it needs to be changed, right? If the performance data is still great, you leave it alone.

    You let it do its thing until it does start showing diminishing returns.

    And ideally, you’re running many variations and tests so that at any given time you’re pruning those ads that are hitting diminishing returns and you’re putting up new ones to see how they perform at Zillow, See how they run? That’s a really good question.

    Avoid using your feelings to make decisions about when to change things.

    It’s it’s not a good indicator.

    Yeah, the data is a much better indicator of follow up questions leave in the comments box below.
