    Christopher Penn 0:13

    In this episode, Dennis asks, what are some email marketing strategies? That might seem counterintuitive? But work? Well? Well, gosh, there are so many marketing strategies for email marketing that can be counterintuitive.

    Let’s get let’s do the intuitive ones.

    First, the obvious ones, your emails gotta be worth reading.

    Right? If you publish an email that doesn’t add value to somebody’s day, it’s it’s a no go.

    Right? No one’s gonna read it.

    Yeah.

    And it is so trite, it is so cliche to say that you got to create valuable content.

    And yet, when I look in my inbox 99% On the marketing, they get us crap, right? It is stuff that you couldn’t pay me to read most of the time.

    I mean, you could pay me you just have to pay me a lot.

    Because so bad, it’s so bad, it is entirely all sender centric, it is all look at us, we’re an awesome company, we’ve got all these awesome products, you should buy something.

    Right.

    So that’s number one.

    Number two, have a consistent sender.

    Right? Again, that’s one of those things that people still do wrong.

    They try messing around and being cute with all kinds of different senders and sender names and things to see if they can get you to pay attention.

    And if you want consistent results, you’ve got to have consistent processes.

    This, there’s no way to, to sugarcoat that if you are inconsistent in your subject lines in your format, in your sender, you’re gonna get inconsistent results.

    And there’s, there’s a time and place for testing for sure.

    But testing should be separate from production.

    And a lot of people that’s not the case.

    Now, there are three things that I do that people consider counterintuitive.

    Number one, I have a really, really, really obvious, bold, obnoxious unsubscribe button, it takes up the whole width of the email.

    It’s all these horrendously bright, changing colors, it looks like a an acid trip.

    And it ends near the top of the email.

    And then there’s another unsubscribe link at the bottom.

    I want people to unsubscribe.

    I should probably clarify, I don’t want people to unsubscribe, who don’t want to be here.

    Right? If they’re not interested out of here.

    Why? Because the very worst thing that can happen is that somebody can’t find the unsubscribe button and they just hit the market spam button, and the email client, if you know anything about email marketing, deliverability.

    Reputation is what matters in email marketing.

    Now it’s stuff like in a free in the sender line like that was how we filtered spam, like in the early 2000s.

    Today, it’s all reputation based IPs, SPF D, Kim D mark, and individual user behaviors.

    If enough people hit the Marcus spam button in Gmail, or Hotmail, or whatever the service is gonna say, Well, gosh, you know, this seems like everyone’s flagging this spam.

    So let’s move it to the promotions tab or does not deliver it at all.

    People hitting that market spam button is so damaging, so damaging to reputation.

    It’s right up there with sending email to email addresses that don’t exist.

    And it’s that bad.

    So you never want to do that.

    So how do you avoid that? You make it easier for people to unsubscribe, you say? Here’s the door.

    Don’t let it hit you.

    Right where the good Lord split? Yeah.

    And that gets people who are likely to complain off your list.

    Now, why don’t marketers do this more, because a lot of the times they’re measured on I hate the term vanity metrics, but they’re measured on metrics that may or may not have any correlation to actual results.

    Just because your email list is big doesn’t mean that it’s good, right? If you send out an email to a million people at five people buy something, your list is really a five, right? And the other 999,995 emails are no good.

    If five people are only the only one to ever buy anything, you may as well just have a list of five.

    And so we are taught a bigger list is better.

    It’s not true.

    An engaged list is better.

    A happy list is better.

    A list that looks forward to your emails is better.

    Bigger isn’t better.

    And so if we get rid of that mindset, then we can get rid of the need to hide the unsubscribe link in two point font in light gray text, the very bottom the email.

    That’s no good.

    Stop doing that.

    So that’s number one.

    Number two blatant subject lines, particularly for sales pitches, a lot of my sales pitches start out saying blatant sales pitch.

    That’s part of the subject lines, this blatant sales pitch, Google Analytics 4 course, I want you to know, it’s a sales pitch,

    Christopher Penn 5:09

    I want you to know when I’m sending you a sales pitch.

    And again, when you look at the tactics your average salesperson uses, they’ll do things like you know, put our E and then you know, our meeting last week or whatever, or, Hey, you got a few minutes, kind of thing.

    We’re all adults, we’ve all been around for a little while.

    We all know exactly what those emails mean.

    You’re not fooling anybody, and saying, I got two minutes.

    You’re gonna You’re two minutes ago, stretch 20 minutes, and it’s going to be a sales pitch.

    No, I don’t have two minutes for you.

    If my subject line says blatant sales pitch Google Analytics 4 course, what happens? When you read that? It sets your expectations? You know what’s in the box, you know, you’re getting a sales pitch, right? What happens if I have a deceptive subject line? Right? Like, check this out? You open the email, and then you’re unhappy like a sales pitch.

    Right? What happens when you’re unhappy? You unsubscribe, right? Or worse you mark as spam again, don’t want that is a blatant sales pitch.

    You know, it’s a sales pitch.

    And then what are you likely to do you just skip it? You hit the delete button, cool, fine.

    If you just hit the delete button, then guess what? You weren’t gonna buy anything anyway.

    So tricking you or trying to trick you is a fruitless endeavor, just call it a blatant sales pitch so that people know what’s in the box.

    And if the subject line is good enough that you know in terms of advertising, what’s in the box, if somebody’s like, gosh, I’ve been thinking about taking a Google Analytics 4 course.

    And look, here’s a sales pitch for one, maybe I’ll at least look at it.

    That’s what I want.

    I want people to have realistic expectations when they open the box when they open the email, and go, Huh, says blatant sales pitch.

    And look, it’s a sales pitch.

    Right? Again, expectations are met.

    No one feels fooled.

    No one feels deceived.

    No one’s unhappy.

    If you open a sales pitch, and it’s a sales pitch, and you’re unhappy, something something went wrong there.

    So that’s number two.

    Number three is I rigorously clean my list, I scrub my list, weekly, of anything that bounces.

    And then I do a full list clean quarterly, I just validate my entire list.

    And I get rid of a lot of emails, a lot of emails go away because they’re marked as you know, no longer valid mailboxes or undeliverable or something like that.

    Again, a lot of marketers really hate doing this, because your subscriber numbers always go down.

    Whenever you clean your list, your numbers go down, sometimes a lot.

    And then your quarterly board report or your monthly marketing metrics review or whatever, you know, this that bright red negative number, and it was like, Oh, what happened? You know, it’s not a failing, it’s not a failing on you as a marketer, if your email list has emails that go bad, right? In the same way, that it’s not a failing that if you buy some fruit at the grocery store, and one of the apples is rotten, you didn’t make it rotten, right? You just bought it just that was a bad apple in the lot.

    What it does do is to keep your reputation clean, because again, one of the markers of spammy behavior is sending a whole bunch of emails to addresses that don’t exist.

    And the more you do that, the worse your reputation gets.

    And it’s quick, it’s not a lot.

    If you look at the deliverability metrics for like Amazon Simple email service, they will warn you, when your invalid email lists, sense, go to 1%.

    Right, if you get 1% of a send, it goes bad.

    Get a warning.

    If you go, I believe, to 2%, your account just gets cancelled.

    Right? Same is true for people complaining like that.

    I think that’s like point 1%.

    It’s really low.

    Their thresholds before they just kick you off their service are really, really low.

    So you cannot afford to have just bad addresses piling up.

    So you’ve got to get rid of them as quickly as possible.

    And the faster you get rid of them at the front end, the more your reputation improves on every single email service provider out there, Hotmail, Gmail, Yahoo, those people who still use AOL, whatever, it’s all fine.

    All of them are looking at reputation all them are looking at what’s going on.

    Right.

    So those would be my my three counterintuitive things and it works.

    It works really well.

    Christopher Penn 9:44

    So my bounce rate on my list hovers around 0.0016%.

    Right, it’s really low, my complaint rate 0.0004%.

    Again, super, super low.

    Well, far below, you know, 1000 times below the threshold where an Amazon SES would say your your account is cancelled right way below it.

    That’s what I want.

    I don’t care if people read every single email, I don’t care if you know people don’t get a ton out of every single email is sent, I don’t care if people don’t buy immediately, in an email, what I do care about as they stick around, I do care that I don’t get complaints, I do care that addresses don’t go bad.

    And I do care that if you don’t want to be here, there’s an easy way for you to leave.

    Right? There’s the big bright unsubscribe button says, Here’s the door.

    Thank you for being here while you were here, we’ll miss you.

    But the content no longer suits you anymore.

    So that’s it.

    That’s those are the tactics.

    And I would encourage every marketer to embrace those tactics, have that big unsubscribe, have those clear as day, you know, can of soup style subject lines, and clean your lists, frequently, aggressively and set expectations, your stakeholders like, Hey, we’re gonna clean the list at the end of the quarter, it’s gonna go down.

    It’s gonna go down a lot, right? But our deliverability will go up, our results will get better and our reputation will improve.

    And those are the trade offs.

    Really good question.

    We could spend a whole bunch of time on email marketing, but these are these are some of the tactics that work really well that I think everybody should try using at least once.

    Anyway, thanks for the question.

    Christopher Penn 0:13

    In this episode, Chris asks, What are your suggestions for improving demand generation, especially for a B2B brand? Well, let’s start by talking about what demand generation means.

    Because there’s a lot of confusion, particularly in B2B marketing, between demand generation lead generation, a lot of folks use those terms interchangeably and they are not the same thing.

    Demand Generation does what it says it does it increases demand for products and services.

    Lead Generation, again, does what it says it does, it generates more leads if you’re doing it, right.

    So how do you create more demand? Not more leads, but more demand? Demand comes essentially in three or four flavors, right? There’s people who know that they have a problem, they know there’s a solution.

    And they know that you are one of those solutions.

    That’s branded demand, right? You see this and you measure this with things like branded organic search, how many people are searching for, say, Trust Insights by name, if they’re searching for Trust Insights, or Katy robear, or Christopher Penn by name.

    They know they have a problem.

    They know this a solution.

    And they know that we are potentially one of the solutions for that problem.

    So that’s branded demand.

    It’s the best kind of demand, right? And you build that demand.

    By the by its very name, its brand, it’s all about brand, and brand.

    My favorite definition of brand is from Jay Frank way back in 2006.

    Said that brand, is the emotional aftertaste of a series of experiences, which I love that brand is the emotional aftertaste of a series of experiences.

    And he goes on to point out, that’s why you can sell grandma’s cookies, and not old people’s cookies.

    They’re the same thing.

    But one has an emotional aftertaste.

    The other one kind of doesn’t.

    What emotional aftertaste does your brand convey? Right? Trust Insights, for example, it’s our company.

    It literally in the name is the idea of building trust.

    We want people to feel comfortable, we want people to feel safe, feel like they’re making a good decision, feel reassured, feel that we put the truth, trust truth, same thing ahead of what’s common in analytics, which is an awful lot of people sort of handing executives and stakeholders the answers that they want to hear.

    Now, sometimes I will be totally honest, sometimes that makes us not the most popular people in the room, right? When the executive says I want to see his number always going up into the right like, well, I got bad news.

    We went down to the right, but it’s truthful.

    And so our brand, the emotional aftertaste we are going after is that feeling of trust, right? That reassurance? There are plenty of brands in B2B and B2C that have an emotional aftertaste to it to them.

    Sometimes it’s not very good.

    But it’s they’re an example of a brand that leaves a very strong emotional aftertaste.

    Harley Davidson, right.

    I just got to say the name.

    And you know, what that brand feels like that evokes an emotional response and emotional aftertaste to you.

    If I say, McDonald’s, well, that may inspire some kind of reaction.

    If I say Google Cloud AI or AWS, those evoke some kinds of emotional reactions.

    That’s brand, right.

    And brand is demand.

    Brand is demand.

    I can’t say that enough times brand is demand because at that layer of demand generation, that’s how people know to find you.

    Right? That’s how people know to trust you to to start the process of lead generation, right, you can’t have lead generation if you have no demand.

    If there’s nobody’s interested in you and nobody knows who you are, you cannot generate leads, and you can but they’re not going to be very good quality.

    Compare that with a name or brand that is trusted, or that is a sure thing.

    And you will have a much easier time generating leads another B2B example back in the 80s.

    And I’ve probably goes further back than that.

    But there was this atheism in B2B.

    Nobody ever gets fired for buying IBM, right.

    In fact, I probably didn’t even need to say the brand for folks who, like me got a little more gray hair.

    And you probably remember that a for ism floating around your business.

    Nobody ever gets fired.

    For Buying IBM.

    Right? That’s rent.

    So that’s the first type of demand generation.

    The

    Christopher Penn 5:06

    second type is we go up that thing.

    I have a problem.

    I know this a solution.

    I know that this brand has a solution.

    Well, the second one is I know there’s a solution, but I don’t know who or what.

    That’s unbranded demand.

    Right? There’s no brand attached to that demand.

    But you know, there’s a solution out there.

    If I’m trying to do regression analysis, I know there’s a library out there that does the type of regression I’m looking for.

    I gotta go look for it.

    I go find it.

    Maybe I’ll ask some friends, maybe ask some colleagues, read some reviews on Reddit, whatever the case may be unbranded demand, which we often measure with unbranded search, but it also is social media conversations and academic publications and q&a forums, unbranded demand is that second layer, how do you create unbranded demand you somebody knows they have a problem, but they don’t understand the solution.

    So you educate you educate you become an educator, and by the way that builds your brand.

    To help people understand, Oh, I’m dealing with being blacklisted in my email marketing.

    Oh, it’s because I didn’t set up any my deliverability protocols.

    Okay, who fixes it? Who does that? Who can fix that? For me? I don’t want to fix it myself.

    Who does that for me? That’s unbranded demand.

    And then the third layer is, you may not know that you have a problem.

    You may know something’s wrong, but you may not be able to a to elucidate on what the problem is that you just know something’s wrong, hey, our web analytics numbers are down 40% This month, right? It can make you feel like I don’t know what to do about this, like, what does this mean? What should we do what’s wrong? That’s the start of demand generation problem, those problems begin the creation of demand, right? That pain, that discomfort that ill at ease that dis ease becomes eventually demand.

    So the question you have to tackle is which of these three layers of demand right, the creation of raw demand itself with problem identification, unbranded demand, where your customers are looking for a solution? They’re trying to figure out what the solution should be? And then branded demand that you are the solution, which of these things is your problem? The further away you get from the lead, right? The the less control you have over it.

    Right? So for example, Hubspot for years, spent like 10 years on hundreds of millions of dollars building the unbranded term, inbound marketing, right, there was a problem.

    Marketers were struggling to build demand.

    They’re struggling to get results, and Hubspot, like okay, we’re gonna go and create a new category, we’re going to create an unbranded brand, right, a nonspecific branded inbound marketing, which of course, they own.

    And after 10 years, and 100 million, they successfully owned that category, they’ve built unbranded and branded demand at the same time.

    Now, if you don’t have 10 years and100 million, that’s probably not the best approach to take.

    But the further away you get from lead generation, the less control you have, and the more expensive it gets.

    Because you are trying to essentially highlight to people Yeah, you actually do have a problem.

    And the problem is your emails aren’t getting through, or your problem is you’re not being found in Google, or the problem is, your your leads are down.

    And here’s the solution.

    And then here’s how we implement the solution.

    So which of those three layers is your demand? Weakest in? And can you fix it? Do you have the resources, the budget the time to fix it? Because sometimes you don’t have the time, right? If your VP is breathing down your neck, like, hey, it’s a it’s a month left in the quarter.

    And we’re our lead numbers are off for 2%.

    What are you gonna do? You don’t have time for a 10 year brand campaign, right? Because you got to make your quarterly numbers.

    So those are my suggestions, figure out which layer of the brand and demand sort of matrix you’re weakest in and then fix what you can fix.

    Right gets to start digging in, start building your brand, start building unbranded demand, and then start helping customers understand that they do, in fact, have a problem if they actually do.

    Really good question.

    We could spend a whole bunch of time on this and maybe we will another time, because I think it’s important that we understand that a lead generation demand generation are not the same thing and be the three different levels of demand, have three totally different implementations for building and creating that Demand anyway thanks for watching I’ll talk to you soon if you’d like this video go ahead and hit that subscribe

    Christopher Penn 0:13

    In this episode, Kaley asks, what kinds of predictive analytics modeling is in Google Analytics 4.

    So this question has two answers.

    For the end user, you and I, very little, if you go in the Explorer hub, there is the ability to do anomaly detection and a little bit of forecasting.

    In Google Data Studio, you can do things like slap trend lines on data.

    But for the most part, there isn’t a lot of predictive analytics that is accessible to the end user in such a way that you can use it to forecast what’s likely to happen.

    There is really good anomaly detection.

    So you can program Google Analytics, even on an hourly basis to say like, Hey, when, you know, traffic gets the exceeds 500% of the previous period, raise your hand.

    That stuff works really well.

    But in terms of predictive analytics, not a whole lot.

    The second answer is that behind the scenes, there’s quite a bit of predictive analytics going on.

    Google is using a lot of imputation algorithms to deal with missing data.

    Because, you know, on average, like 2030 40% of the data that we collect from our websites and stuff is missing, right? Privacy, things consent not being given for tracking bugs, ad blockers, you name it, there’s so many different technologies that are built to take data away from marketers, that software like Google Analytics has to essentially fill in the blanks.

    It’s best guesses based on the behavior of people on your site and matching that of people who have been on your site previously to have those same behaviors, looking at the demographic and psychographic and stuff data that they would have had.

    So you have this known audience.

    And you have this unknown audience that the unknown audience behaves exactly like the known audience.

    Google’s predictive analytics says, Okay, this unknown audience probably is like this known audience.

    So this is all Asian guys 40 to 50 years old.

    And this group here behaves exactly like Asian guys 40 to 50 years old, this group is probably asian guys 40 to 50 years old.

    As a rough example, if you want to leverage predictive analytics yourself.

    With Google Analytics, you’ve got to get the data out of the application yourself.

    And use your own forecasting software to do things like forecasting by channel or forecasting by campaign, and so on, and so forth.

    And if that’s a doable thing, Google Analytics has inversion for the GA for Data API.

    And it’s pretty good.

    There is a lot of useful data in it.

    It’s not sampled, like Google Analytics 3 data is.

    And so you can do some pretty robust forecasting off of it once you can get the data out of the application.

    But the challenge there is that for a lot of folks, that’s a bit more technical, heavy lifting than a lot of folks are accustomed to doing.

    Now, that said, there is no shortage of third party vendors that are offering some kind of software for sale, that can can do similar things.

    But the data is there, it’s all done the same way you take data out of the GA four API, you clean it up, you format it into a time series and say, Okay, let’s forecast, let’s predict what’s likely to happen in the next 3045 6090 days, based on back data.

    In some ways, I don’t think it’s a bad thing that there isn’t predictive analytics, but to do Google Analytics, 4.

    Because predictive analytics, as we all know, can be really, really wrong.

    Sometimes, particularly when you are in an uncertain environment, when you’re in an unstable environment.

    For example, there’s one client that just spent a whole bunch of money on a campaign and that that campaign, in the historical data creates this massive distortion, that kind of screws up forecasting, because you know, for a month, their results like crazy high, and then they ran out of money, and they all they turn the dials back down.

    And they they don’t, they can’t replicate that.

    And so we can’t forecast from that, because it’s an anomaly.

    We actually have to remove it from the data so that it doesn’t screw up other forecasts.

    And that’s not something that Google is going to roll out to the end user anytime soon, because it requires data cleaning, right? It requires subject matter expertise.

    It requires knowing what your company did, and so it will be very easy for Google to forecast the wrong things.

    Christopher Penn 5:01

    because it doesn’t know what happened behind the scenes, it doesn’t know that your your cmo got drunk one night and swiped a credit card and put a million bucks in your Google ad system as an example.

    Right? He doesn’t know that.

    So it can only forecast the day it’s given.

    And there’s so much uncertainty that it’s it’s very challenging.

    So, no, there’s no substantial predictive analytics modeling capabilities exposed to the end user in Google Analytics 4.

    You’ve got to do that yourself.

    Good question.

    In this episode, Michael asked how do you spot trends and hits? What should you look for? I mean, if I was super, super good at this, we wouldn’t be having this conversation because I thought it’d be retired.

    It depends on the context within statistics, a trend is detectable once you start having some form of sustained growth, right.

    So if you’re looking at a numeric series of some kind, you see a change in, in that that is sustained, you know, three, four, or five, six different data points where it’s going up what’s going down or something like that.

    But there’s, there’s something that is a sustained amount of momentum.

    That’s the mathematical answer of how you spot a trend.

    But more broadly, when people are asking like, how do I know what the next big thing is going to be? What should we be focusing on what’s going to be the next big hit, we don’t know.

    We have no way of knowing what the next big hit is going to be.

    Because it’s it’s so from a mathematical perspective, it is such a complex equation with so many inputs, that there is no way to accurately predict that outcome.

    Right, it’s like trying to pick a stock in the stock market.

    If the stock market was the only place where you could do business buying and selling stocks, you could probably come up with some predictive algorithms, that would work.

    But because you have all these other financial mechanisms, hedge funds, high frequency trading, Shadow markets, private trades, all the stuff that isn’t fitted into the outcome data, you can’t build a model, many, many companies have tried building a working model to predict the stock market and zero have succeeded.

    And I can tell you this with confidence, because if one of them had succeeded, they would have all the money.

    It would be no other viruses talk about there’d be one company that have all the money.

    And that would be that more broadly.

    From a cultural perspective, from a people perspective, again, we don’t know, we have no way of knowing what’s going to take off, what you can do is pay very careful attention and look at data very, very frequently.

    So there are some great listening tools, conversational intelligence tools out there Talkwalker, for example, good friend of mine, the folks over there that provide really good data tools to provide information that you can then put through predictive algorithms, Markov chain models, neural networks to take the, the fancy, forecasting software of your choice.

    And you can start to look for those patterns of growth.

    But even then, it’s not necessarily going to be all that clear.

    Here’s a simple example, if you were to go to Google Trends, go to trends.google.com.

    And type in Tiktok.

    Switch the timeline to all time, you would see that it took a really, really long time, years for the service to catch on.

    Right? When you look at that graph, you’re looking at it go wow, it would have been really, really hard to detect that this is the thing.

    So what do you do? How do you add into this? The answer is in the target market that you care about, wherever that market is, you’ve got to be listening.

    You’ve got to be in the mix, listening to what people are talking about and listening for conversations, and trying to understand what it is that people what catches people’s attention.

    For example, as of the date of this recording, which is July 24 of 2022 a new video game stray has hit the market and in a number of discord groups that I’m a member of conversations are happening a lot about this game, gamers are talking about it.

    It made a big splash and more importantly, people seem to like it, people seem to enjoy it.

    And as a result, it appears to it’s going to be a hit.

    Now it’s early.

    Now it only released a few days ago.

    But when you’re in multiple communities and you see the same thing being talked about, that’s a pretty good early indicator that you should pay attention to it should dig in a little bit see if see if there’s a there there.

    We say the same thing about for example, when a new social network pops up if you see enough people in your target audience talking about things that’s why it’s time to go alright you know when You’d go, at least sign up for an account, get our name reserved, maybe see who else is there and see what the general conversations are.

    That’s one of the easiest ways to

    Christopher Penn 5:12

    not predict a hit or trend.

    But to catch it early enough that to the outside world looks like you predicted it.

    For example, in January of 2020, I started reading a lot, a lot on Twitter within a very specific community about this new disease.

    It’s called an cov 2019 novel Coronavirus.

    And some of the folks who were in these, these disease communities were saying this is this is going to be a thing.

    The numbers at that point like they were less than 500 cases.

    Around the world at that point, there was like a couple 1000 5000 or so in China that was about it.

    It was quiet.

    It was a relatively quiet thing.

    But it did look like a quiet thing, right exhibited signs of exponential growth.

    Two months later lockdowns came, right, April, March, end of March, April 2020, it became a thing and then you had the main wave, the alpha wave, the delta wave Omicron Omicron, ba two Omicron, ba five, and so on and so forth.

    And here we are two years later.

    And in those early days, I went to an event.

    And I said, I was the only person wearing one of my my P 100.

    masks and people like what is wrong with you? Dude, you’re what’s up with that.

    And I sent an email to events are speaking at, you know, later in the year saying, Hey, I think this might be a thing.

    So offering to record my session this video in case in case it it becomes a thing because it was exhibiting mathematical signs and exponential growth signs of becoming a thing.

    We all know what happened, right? And I got emails later that year, and the next year, I feel going.

    Yeah, you’re right.

    How do you know you? I didn’t know.

    I wasn’t predicting it, I was just paying attention to what’s happening.

    In the moment, we’re seeing the same thing happening now.

    Again, it’s July 24, of 2022.

    With stuff like monkeypox, it’s picking up steam, right? The mathematical trends are in his favor.

    And so gotta pay attention when the math shows that early signs of an exponential trend, which you can find mathematically, it’s time to pay attention to it.

    The challenge is, you’ve got to know where to listen.

    And that’s the part that marketers have, I think the most trouble with marketers spend so much time listening to themselves and to the people within their companies, and not nearly enough time listening to their customers, not nearly enough time listening to the audience spending time.

    Online, even in your audience.

    When you spend time in your audience, you hear stuff, when you hear stuff, you can start quantifying it, and identifying what’s gonna be a thing before it’s a thing.

    Because it is still technically a thing.

    Exponential growth just doesn’t look like it until it really looks like it.

    But that’s the way exponents work, right? Doubling a number that doubles every time you know, it goes from one to two, whoo, big deal, right? Two to four, no big deal, then you get to 64 128 256-512-1024.

    And you’re like, oh, this thing’s growing pretty fast.

    Now.

    That’s the challenge our brains as people we don’t we don’t do exponential calculations very well, if at all.

    We can’t see it.

    So we’ve got to rely on our tools to do it for us.

    So that is what I would suggest is good listening to identify topics and things to pay attention to.

    And then good analysis tools to look at the data and say, are any of these things exhibiting exponential growth? If so, should we be doing something about it? Really good question.

    It’s a question that requires you to actually have a the time to listen carefully in all the right communities and be the technology to to analyze it to look for those trends.

    So good question.

    Thanks for asking.

    Christopher Penn 0:13

    In today’s episode, Sheila asks, Why does your email newsletter come out on Sunday? Don’t you think it’s rude to ask people to work on the weekend, email should be saved for the workweek.

    I mean, you don’t have to read it on Sunday, you can wait.

    I mean, if it’s, if it’s really bothering you just leave it unread in your inbox till Monday.

    The reason it comes out on Sunday is because when I started the newsletter, I was working at a company where employees side hustles were somewhat discouraged, right? At least during work hours.

    The company at the time was this was actually an email marketing company, and run by accountants and accountants being accountants, no offense, if you are an accountant, but they were not super thrilled about employees doing anything other than devoting all their time and focus solely to the company, even if there wasn’t necessarily work to be done at the time.

    And so a consequence of that when I started this newsletter, was that I decided to do it on the weekend, right, I’d write it and send it on Sundays.

    That way, I could a devote the right amount of time to it, to putting it together and be, it wouldn’t get me in trouble with the folks that work.

    Right? Because again, they they weren’t thrilled by it.

    Now, granted, that was 11 years ago.

    Now.

    That’s how long this newsletter has been around.

    And that company is now like, two, three companies in the rearview mirror.

    So there isn’t a need anymore for me to send it on Sundays.

    It’s just what I do.

    It’s it’s become a habit.

    It’s, I’ve structured my routine.

    So that the habit of sending out this newsletter means it’s predictable.

    And it works in my schedule.

    And it’s predictable for you, in the sense that it arrives in your inbox on a specific day of the week.

    And again, it’s entirely up to you, when you read this newsletter, if you read it at all.

    I mean, that’s fine, you don’t have to the unsubscribe button is should be pretty obvious.

    Do I think people should be working on the weekend.

    Again, that’s your choice.

    That is your choice.

    If you work in a corporate culture where you feel like you need to, to get ahead of the week.

    Do it right, if you feel like you need to decompress and not think about work at all during the weekend, do it.

    It’s all individual choice.

    And there’s really, there’s really nothing that I would have to say, direction wise that would be useful, right? You’re presumably a competent, consenting adult, you choose to do what you want.

    And in the privacy of your own time.

    I do think that at least for salaried employees, it is unrealistic and unfair for an employer to expect you to work on the weekend, if you’re being I mean, if you’re getting paid for a 40 hour work week, and you’re working 40 hours during the week, then you probably should be not working on the weekends, because it’s actually not getting paid for it.

    Right.

    Or you’re saying that you’re getting paid on a per hour basis less than what you actually are.

    I’m a big fan of if you’re working you should be getting paid.

    In my case, also, now that I co own a company.

    I mean, we’re always working.

    That’s entrepreneur life, you know, you’re always working in, you’re never not working because you want your company to succeed.

    And you will do what you have to to make sure that you keep moving the ball forward, you keep doing something, these videos that I’m putting together that I record these videos on Sundays on Sunday afternoons typically that way it doesn’t take up time during the work week.

    And also that gives me the ability to, to compile questions and think carefully about the answers throughout the week.

    Before I record the video that way, it’s not just sort of a dis disorganized off the cuff of rambling response.

    It’s an organized, rambling response.

    So that’s why the newsletter comes out on Sundays.

    Again, read it whenever you want.

    There’s um I’m not looking over your shoulder, I’m not looking at my email stats and saying, oh, gosh, Sheila didn’t read this on Sundays, she’s Nope.

    That doesn’t happen.

    Christopher Penn 5:10

    I don’t I don’t look at that information at all.

    The newsletter is for your benefit.

    It is, coincidentally also for my benefit to my company’s benefit.

    But it’s first and foremost for your benefit.

    So consume it in whatever form you want, whenever you want, however you want, or not at all.

    And that’s, that’s totally cool.

    It doesn’t bother me, one way or the other.

    I hope it gives you some benefit.

    If it doesn’t, then I would ask you to email me and tell me, Hey, I’m not getting anything out newsletter anymore.

    And here’s why.

    Because that kind of feedback helps me make things better helps you make the changes, at the very least run a survey asking people.

    So what do you want? What can I help you with? What are the things you would like to know? It’s one of the reasons why at the end of every, every post on the blog, when I post these videos up, there’s a whole thing saying, hey, if you’ve got questions, click on this link to ask them here.

    Because I need those questions to be able to provide you the value that you’re looking for.

    So that’s where it comes out on Sundays.

    It’s it’s habit at this point.

    It does seem to work pretty well.

    A fair number of people probably about a third of the list actually reads it on the weekend because some people like to read it and be able to have time to digest it not get caught up in the workweek.

    But the other two thirds read it you know Monday, some a few on Tuesday.

    But that’s that’s what the stats show.

    Anyway, read it when you want.

    It’s it’s up to you.

    Either way, I hope you enjoyed it.

    Hope you get value out of it.

    Thanks for Thanks for the question.

    Take care.

    Christopher Penn 0:13

    In today’s episode, Brandon asks, we’re really struggling trying to find qualified candidates for open positions.

    We’re paying reasonably competitively, but we can’t find anyone to fit the role.

    What do you suggest? Okay, so the, the Yellow Flag immediately is saying we’re paying reasonably competitively.

    The reality is that talent is still at a substantial deficit, right? We still don’t have enough people that stayed in the industry.

    And so available talent that is willing to work for you, is going to be expensive.

    So there are two different ways to handle this one, the obvious way is to pay more, right, instead of being paying competitively out compete the market, you might have to have smaller headcount.

    Right? If you are hiring for five positions, and paying reasonably competitively, you could probably hire for three positions and pay exceptionally well, that would certainly be a big help.

    The second thing to do is to consider the qualifications of what it is you’re looking at.

    Because one of the things I think companies are doing most wrong right now is they are looking for very short term investments.

    And I guess the way I would put this is, companies seem to be looking for employees that are like widgets that you can just pick up like a cog, put it in the machine, and it’s ready to go and boom machine keeps running, you’re going to pay a lot of money for that capability, you’re going to pay for someone to hit the ground running as the cliche goes in, literally every job description there is, if you are willing to invest in people sort of grow your own.

    You don’t have to pay outrageous sums.

    As long as you’re willing to trade off.

    Yeah, you’re not going to hit the ground running, that’s gonna take 3060 90 120 180 days for a person to get up to speed.

    But once they do, then a you’ve helped advance their career.

    B, they might have a bit more loyalty to you, because you’ve clearly shown you’re willing to invest in them.

    And see, it opens up the candidate pool considerably.

    Instead of looking for somebody with, you know, three to five years experience, what would it look like? For you to identify someone really smart, really eager? Good attitude, strong aptitude, but no experience? What would it look like to hire a person like that? And if you have to pay the hit the ground running person, $100,000 a year? Could you find somebody who truly is entry level, start them off at 60? And say, Look, we know it’s going to take us six months to get speed, right? But as you do as you grow into the role, will teach you what you need to know as long as you’re capable of thinking as long as you’re self directed and motivated.

    As long as you can follow directions and ask questions when you get stuck.

    We can make this roll work for you.

    Like I said, that opens up the candidate pool considerably.

    When you look at the number of people who could work for you, but don’t necessarily because of your current requirements.

    Changing to a instead of a hunting strategy, more of a farming strategy, right instead of trying to find the the perfect deer in a rough winter.

    Maybe you farmed all summer, and now you’ve got crops to eat over the wintertime.

    But it took a lot more work.

    It took a lot more work to get to that point.

    Think about all the categories of people who might have aptitude, might have attitude, but don’t have a stitch of experience.

    Folks who maybe never completed a college degree, folks who are veterans, folks who are in some way impaired but still perfectly capable of doing a job.

    It’s just that they’ve not had the opportunity folks who come from economically or socially disadvantaged backgrounds.

    Folks who come from economic opportunity zones, right? In the USA we have huge numbers of people who are example on a American Indian reservations and things.

    People are people brains, our brains, right? For a lot of the work that we do in marketing,

    Christopher Penn 5:09

    this, the physical, it really is just the case for the computer in here, right.

    So what this looks like and where it’s been is less relevant than what the machinery in here can do.

    So if you are willing to broaden your requirements, if you are willing to remove some requirements and spend more time looking for aptitude, looking for attitude looking for affinity for the different tasks, you might find really good candidates who just need a shot, just need a chance.

    And you can start them off as entry level, right, because if they have no experience, they are entry level and you can pay accordingly.

    But commit to growing them, right.

    This is like venture capital.

    If you think about hiring as venture capital, you can pay full price for a company that’s already a hit.

    Or you can invest in a whole bunch of startups.

    Nine of the 10 MAE won’t make it but that one that does, is going to meet your they’re going to knock it out of the park, right, you’ll recoup your investment many times over.

    The same thing is true of people, you’re not going to hire rockstars every single time.

    And frankly, if they’re like Keith Richards, right.

    But if you hire a bunch of folks, and invest in them, acknowledging Yeah, some of them aren’t going to work out, maybe the majority of them aren’t going to work out.

    But taking that attitude of investing, and growing your own talent, dramatically relieves the pressure of your candidate pipeline, when you have open positions.

    Look at internships, right paid internships, paid internships are a great way to identify young talent.

    And it’s a place where you can take hesitant to call it risks, because just because someone has no experience doesn’t mean they’re a risk.

    But you can be more adventurous in what qualifications you do or don’t need, right? Find a mom who’s wants to return to the workforce only part time, right? That may be a great candidate, somebody who has a perfectly functional brain, but has circumstances that needs more flexibility, as long as the work gets done.

    But it doesn’t really matter.

    So I would suggest that if you don’t want to spend a gazillion dollars hiring, ready to go people, and you have a corporate culture that permits you to be a little more adventurous in your hiring that you look at all these pools of less traditional candidates looking for talent in the in the most literal sense, looking for good aptitude, good attitude, people who want a chance people who want to want to try making their mark and you’re willing to grow with them, you’re willing to invest in them.

    Again, when you do it right.

    retention becomes a lot less of a problem.

    Right, as long as once they’re up to speed, you’re paying them competitively with what the rest of the market is paying.

    Once they’re at that point.

    They are much more loyal to you.

    And and again, assuming you’re not like a jerk to work for, but give that some thought.

    give that some thought.

    That’s how I would solve the qualified candidates pipeline issue in the long term and fully acknowledged it’s not going to solve your problem today, right? But solving your problem today is going to require you to dramatically overpay.

    Investing in people in the long term will solve the problem on a mostly permanent basis.

    Really good question.

    Christopher Penn 0:13

    In today’s episode, Catherine asks, How do you know which is the right algorithm or model to choose for any given data set? That’s a tough question.

    That’s a tough question, because there’s so many things that can go into those choices.

    The first, obviously, is the data itself, what kind of data you you’ve got, right? If it’s a mix of categorical and continuous numbers and not numbers, that can shed some light as to as to what algorithms are just off the table or not.

    The big thing, though, is, what is the intended outcome, right? Because there’s two fundamental tasks in data science and machine learning.

    There’s regression and classification.

    Classification is hey, we got a bunch of data, we don’t know how to organize it, let’s classify it so that it’s easier to understand the clumps of of data, maybe there’s a way to describe what those clumps are.

    Regression is given a known outcome, what things most closely represent that outcome are most likely that outcome.

    And within each of those two families, you then have a whole series of techniques, like, you know, nearest neighbors, for example, or SVM, for classification, or gradient boosting or lasso and ridge regression for regression analysis.

    The question always is what are the what are the measures of performance that you’re trying to use? So, in classification, the most common metric is called the area under the receiver operating characteristics or AUROC.

    And essentially, it’s a measurement to say how good a dataset classification algorithm or model is, how well it performs, right? Whether it what percentage of true positives versus false positives, it gives off.

    It’d be like, you know, you get a bunch of fruit, and you classify, these are apples, these are pears, these are grapes, etc.

    And your measure of success is how many things wrong you get right? Like, maybe get some really, really, really large grapes, and you misclassify a bunch of them as plums.

    That would be you know, that would have a lower AUROC score than if you were correctly set up.

    These are their large grapes, but they’re still grapes.

    That would get you a higher AUROC score.

    In regression, the most common measures there are the root mean squared error and the R squared number, which are descriptors of how closely a result fits a line, right? So if you have this, this line, or this curve of the regression, how closely does it fit against the existing data? Knowing that lets you know how accurate your analysis was.

    Now, you have a bunch of different tools out there right now, that can sort of test to see how different algorithms perform on data.

    One of the ones I use a lot is called IBM Watson Studio auto AI, you give it a dataset, you give it the outcome you’re after, and it tests all the different algorithms and models and says, Hey, here’s the ones that have the best performance based on the characteristics you’ve specified, like the highest R squared number, the lowest root mean squared error.

    Those tools are huge, huge time savers, because otherwise, you have to test everything by hand, which I’ve done, it’s not fun.

    There’s more and more automated machine learning that does that sort of thing where you give it the outcome and the data, and it will just test out a bunch of things and then let you know, hey, here’s what I found.

    And then it’s up to you, as the data scientist to say, Okay, I think this one is the best blend of performance and accuracy, or this is the best blend of accuracy and fits the kind of outputs we need.

    For example, there are some regression algorithms that cannot output, what’s called variable importance of all the variables that went into the regression, which ones are the most important, which ones have the highest relationship to the outcome we care about in marketing? That kind of algorithm would tell us what channels are working, right.

    So if we’re talking about marketing channels, that type of analysis would be we want to know the and if there’s an algorithm that doesn’t provide variable importance, its usefulness to us is going to be pretty low.

    Right? If that’s if that’s a key requirement.

    So I guess the long answer to the question is, knowing what your requirements are or knowing what your model KPIs are.

    And then using the automation software of your choice to test a bunch of things or do it manually.

    I mean, that’s, that’s always a viable option

    Christopher Penn 5:15

    to see which algorithm or model performs best given the data set.

    And given the requirements that you need to fit it to.

    It’s not easy, right? It’s not fast.

    It’s there’s no easy button.

    Because even if your software chooses an algorithm that fits well, if anything changes in that data set, you’ve got to rerun the process all over again, possibly multiple times.

    So it’s, it’s not a one and done.

    It’s a living, breathing thing.

    But good question.

    It’s an interesting question, and in a very challenging one.

    It’s one of the areas where automated machine learning really can offer substantial measurable benefits to folks who are engaging in machine learning practices.

    So thanks for asking.

  • Marketers, Stop Funding Disinformation!

    One of the questions people ask most when we see the awful consequences of disinformation – vaccine rejection, mass shootings, seditious acts – is what we can do to prevent it.

    I’ll give you something fast and easy you can do today if you’re in charge of advertising budgets: stop funding disinformation sites.

    It’s super easy to do this if you know your way around advertising systems.

    First, who shouldn’t you fund? This is one of the rare cases where there is a legitimate “both sides” argument: there’s garbage on the internet from radical left-wing and radical right-wing sites that are equally flat out wrong.

    So your first stop should be to AdFontes’ Interactive Media Bias Chart. Take a look at the chart and you’ll see it’s divided into political spectrum horizontally, and truthfulness vertically:

    Ad Chart

    I strongly encourage you not to buy ads from companies in the misleading info category and below, regardless of political position.

    Consider not buying ads on sites that are on the extremes, either. If you don’t love the hyper-polarized environment today, then you shouldn’t put ad dollars in those companies’ pockets.

    Once you’ve got your list of sites/accounts, head over to your ad systems. For example, in Google Ads, you’ll find the placement exclusion lists section under settings:

    Placement exclusions

    Call it whatever you like, then start putting in domain names of sites that are in the disinformation extremes:

    Do not advertise

    Congratulations, you’ve now avoided giving money to sites actively promoting disinformation. Rinse and repeat on every platform where you have the ability to do this – and if an ad platform doesn’t offer these capabilities, then consider not advertising on that platform, lest your money be spent doing things that are probably in opposition to your corporate ethics and values.

    For good or ill, money runs the world. We get what we pay for – and if we, as marketers in control of ad budgets – are funding disinformation, then that’s exactly what we’ll get.

    Christopher Penn 0:13

    In today’s episode, Catherine asks, what’s the first thing or set of processes you do when you receive new data from a customer? Probably exploratory data analysis.

    Alright, exploratory data analysis is the data science and machine learning equivalent of looking in the fridge before you cook.

    Right? So you look at, you open up the fridge, you look at what’s in there, and you say, Okay, I’ve got chicken, I don’t have steak, I’ve got onions, but they don’t have peppers, I’ve got carrots, but I don’t have celery, and so on and so forth.

    And based on what you’ve got in the fridge, that dictates what kinds of things you are or not going to cook.

    If you’ve got your heart set on steak, but there’s no beef in the fridge.

    You’re not having steak, right? So when a customer hands over new data, first thing is you look at it, you investigate it, you say, Okay, what’s in the box? Like? What did the customer give me? What condition? Is it in? Is it in good condition is in bad condition? Are there lots of missing variables? or missing data points? Are things labeled correctly? Does the data answer the question that the customer is trying to ask, that’s a critical part of this, if a customer says I want to know social media ROI, and they provide no cost data, you can’t do social media ROI, there’s just no way to do that you’ve got a substantial missing ingredients like baking a loaf of bread, and you’ve got no flour.

    Now, you’re probably not breaking baking bread there.

    So that’s the first part is exploratory data analysis.

    And that’s, you know, eight different parts.

    So you have your goal and your purpose.

    You have your data requirements and data collection, you have your initial analysis, like looking at it, your descriptive analytics, see what kinds of dimensions and metrics are there? You look, do your data quality stuff, like what kinds of quality data is in there? There is recurrent requirements, verification, you’ll look at the data and go okay, Does this answer the question that’s being asked of it.

    And if it doesn’t, you got to start over.

    After that, you’ll do prep, which is cleaning, centering, scaling, etc, you’ll probably do some feature engineering, where you’re going to create new features out of existing ones, like day of week or hour of day, from a date, and then your modeling or your insights, depending on whether you’re going to be pushing a model into production, or just doing an analysis, those are the steps that are vital.

    Anytime you get new data, it’s like anytime you get maybe a delivery of groceries, right? And you have a company that doesn’t shopping for you, and they drop off the box on your doorstep.

    And the first thing you do is you open the box and go okay, did they get my order, right? I ordered apples and there’s pineapples.

    Okay, that’s, that’s not helpful.

    That’s where you start.

    Because that will also help avoid failure later on.

    If a customer hands you data, and that data, there’s something wrong with it.

    The sooner you catch that, the less time and money you waste, right, the less beating your head against the wall, or worst case scenario, you think the data is fine, you’re running an analysis on it, you hand off the results to a customer and it’s wrong.

    And it might be wrong in a subtle way in a way that you don’t catch.

    But then, you know, a month a quarter a year later, the customers like, hey, our business is going down.

    Why? Well, because you made an analysis of bad data.

    Right? It’s like you you’re you eat something that tastes fine the next day, you’re sick.

    Well, yeah, yeah, ate some food that was contaminated.

    And you know, maybe you the next day, you find out that that was not the case.

    Or if it was like a really bad mushroom, you might die 10 days later, because liquefied your internal organs, which can happen.

    So that’s the first most important part, you got to open up that fridge and look inside and see what do we have? And can it make the things that we want to make? If you skip that part, if you skip the exploratory data analysis, you will be in a world of hurt, because at some point, you will be handed data that isn’t clean, that isn’t complete.

    That isn’t correct.

    And you will use it and you will lament your choices.

    I guarantee it.

    So that’s the first and most important step to do before you do anything else.

    Good question.

    Thanks for asking.

    Machine-Generated Transcript

    Christopher Penn 0:13

    In today’s episode, Catherine asks, What’s the most time intensive part of data science? Well, the most time intensive part by far is a Data Prep and feature engineering.

    These are the stages where you are taking data, cleaning it while examining it, cleaning it, preparing it for analysis, preparing it for modeling, doing feature engineering and adding on new features and things.

    That’s probably 80% of data science, for real.

    The actual in depth analysis, the actual machine learning if you’re going to be doing it for machine learning, that’s like 10 to 15% of your time.

    The reason why Data Prep is so time intensive is that despite the raft of companies and software and tools that they claim, they can automate it all away.

    You can’t, you can’t automate it all the way.

    Because in so many cases, what you’re dealing with is stuff that is different every time.

    Right? When you’re looking at a data set of nutrition data, it’s got certain characteristics, when you’re looking at motor data, when you’re looking at environmental data, when you’re looking at email marketing, statistics, all of these things are datasets that are unique and different.

    And though there are common processes and techniques for doing data prep and feature engineering, there is no one size fits all.

    And there’s certainly no way to easily today easily just handy to set to a computer and say, Hey, do all my cleanup and prep and feature engineering for me.

    Because you don’t these machines don’t necessarily know what’s needed.

    They don’t necessarily know what procedures would make sense to do and what procedures, there isn’t a lot of sense in them.

    For example, suppose you have a date field in a, an email marketing dataset, the software would know to to make sure that it’s a date field, and that’s formatted correctly and things like that.

    But it wouldn’t necessarily know that you might want to extract out day of week or hour of day, it also wouldn’t know you don’t typically want you know, day of month or day of year, those are not necessarily going to be things that from an email marketing perspective are going to lend a whole lot of insight, maybe they will, maybe they won’t, depending on your email marketing strategy.

    But we as the data scientists would know based on our subject matter expertise, based on our skills, and then based on our domain knowledge of the email marketing that sometimes those extra added engineered features are good idea, and sometimes they don’t add any extra value.

    That’s one of the reasons why data science is so complicated.

    And why it is so hard to find talent in the data science field because you need somebody who is both a subject matter expert in data science, but also a subject matter expert in whatever it is that the you know, the datasets that you’re studying for what that industry is someone looking at, for example, COVID data is going to have a very different understanding of what features are important, you know, based on virology and immunology, than somebody who’s doing data analysis on car engines, right? They’ll have similar techniques, but they’re gonna deploy them in very, very different ways.

    Someone who’s an expert in engines is going to be looking at factors like mean time between failure, whereas somebody looking at COVID data is probably going to be looking at things like genetic drift, like antigenic drift and phylogenetic maps.

    Those are very different tasks.

    And you need to have the subject matter expertise in that domain, to be able to know what features to include to know what features are missing, especially.

    And then whether or not you can engineer the data set to repair some of the missing data.

    I don’t foresee a day when you can just simply hand a dataset over to a machine and have it do all that cleaning and prep and augmentation and extraction and make it all work seamlessly because it’s different every time.

    It’s like.

    It’s like being a chef, right? Being a chef in a maybe in a food court.

    And there’s just one big restaurant that serves every cuisine.

    You don’t know what the next person is going to ask.

    Maybe they want chicken chow mein maybe they want Pasta carbonara.

    Maybe they want to pretzel.

    Right? There’s no way to tell.

    And so you’ll have slots of skills and common techniques, but at the same time, every order is going to be different.

    So Oh,

    Christopher Penn 5:01

    that’s the most intensive part of data scientists science, the time intensive part.

    It is prepping engineering.

    And that’s not going to get better anytime soon.

    The machines can help.

    But even then they still need guidance to pull it off.

    So, I would expect if you are in the field of data science or you are working towards becoming one, that’s where you’re going to spend a lot of your time and frankly, that’s where things go the most wrong because if you don’t have the right data for any models or insights, it’s like not having the right ingredients to cook with.

    Right if you’re trying to bake bread and you got a bag of sand.

    Doesn’t matter how good a cook you are.

    You’re not making an animal over bread.

    Anyway, really good question.
