  • Conversations and Social Media Goals

    Conversations and Social Media Goals

    Jen asks, “How important are conversations to social media goals?”

    It depends on the goal, and it depends on how conversations advance that goal. For example, if raw engagement is a goal, conversations with people – especially in public social media forums – may be very relevant. On the other hand, if website traffic from social media is the goal, conversations may not necessarily play a role.

    Conversations and Outcomes

    How would we know whether or not conversations matter? This is where we do some data analysis. Let’s say our goal is website traffic from Instagram. Over on the Trust Insights Instagram account, we post our weekly podcast episodes and a link back to the Trust Insights website in the biography.

    Suppose our goal was to get website traffic from Instagram? How would we understand whether or not any of the data could solve this?

    Using a basic correlation analysis, we might examine all the different Instagram metrics provided through the API to see which, if any, have a correlation to website traffic. As usual, this isn’t causation, but at the very least, if there’s no relationship between website traffic and any Instagram metrics, then we can be reasonably certain Instagram isn’t working.

    Instagram Metrics Correlation

    Well, that’s a big load of nothing. In fact, none of the Instagram metrics – conversations included – have a relationship to website users. Comments – conversations – don’t really have much of a relationship to anything.

    Perhaps that’s just because we’re bad at Instagram. Let’s look at a different account, that of American musician Megan Thee Stallion:

    Megan Thee Stallion IG

    We don’t have Megan’s user traffic, so there’s no way to do the same kind of analysis, but we do see that conversations have a moderate relationship to new follower growth, and a strong relationship to likes. It’s likely that with some down-funnel data, we might see conversations having relationships with brand awareness, loyalty, or even purchase consideration. We might want to further engineer out specific features, like what topics spur the most conversations, or what media formats.

    Correlation Still Isn’t Causation

    At this point, if we were managing Megan’s social media, we might want to establish causation. Absence of correlation usually also implies absence of causation, but correlation isn’t causation for sure. So we’d need to run some tests by increasing the volume of conversation – straightforward when you have an account/presence that all your 20 million fans want to engage with more – and then determine if the change in conversations led to changes in other metrics. If Megan were to increase engagement – conversations – by 25%, what other metrics would commensurately increase by 25% or more?

    Conversations is a metric, but only thorough investigation can help you understand whether it’s a KPI. Once you’ve made that determination, you’ll be able to set your conversational engagement strategy.

  • How to Build a Data-Driven Social Media Strategy Plan

    How to Build a Data Driven Social Media Strategy Plan

    Emily asks, "What are your favorite resources for social media strategy planning?"

    The overall strategy for social media planning is and should be tightly coupled to your overall digital marketing goals. What are you trying to achieve as a department or organizational unit? Demand generation? Lead generation? Ecommerce sales? That’s the starting point.

    On my website, I care about four things – consulting opportunities, public speaking opportunities, book sales, and newsletter subscriptions.

    Determine Channel Effectiveness

    Once you have a clear idea of what goal you’re measuring towards, build and run an attribution model. If you’re dealing with mostly digital data, I recommend a machine learning model based on techniques like Markov chain modeling or Shapley values (I prefer Markov). What this achieves is an analysis of which channels already help to drive those conversions.

    For example, I recently changed how I publish content – I’m back to traditional blogging. (the reasons are detailed in this post) When I look at my attribution model for how my site is doing, it’s definitely the right choice. Here’s my model for January 2020:

    2020 Attribution Model

    We see that organic search was the primary driver of conversions, impacting 58.9% of conversions and yielding 184 conversions, followed by email at 16.5%, yielding 52 conversions.

    Now, let’s look at how January went, with my new strategy:

    2021 Attribution Model

    That’s a big difference. Organic search is now 51.2% of conversions impacted, but the absolute number is more than double at 387 conversions. That’s a huge jump, to double the number of conversions from organic search year over year.

    Email continues to bring up second place with 36.2% of conversions impacted, with 273 conversions, also a nice gain over the previous year.

    What about social media? After all, we’re trying to build a social media strategy plan here. In both models, Twitter has driven the most social conversions; Facebook was doing okay in 2020 but has dropped down to the middle of the pack in 2021.

    So, I have a good sense of which social media channel is working. Now the question is, how do I get more out of that channel?

    Determine Channel Tactics

    Once we know what channel’s working, it’s time to figure out WHY it’s working. If we can crack the code about what makes a certain channel tick, then we can do more of what works. To accomplish this, we first need to know what data is available.

    For this exercise, I’m looking at Twitter. It’s consistently a winner, year-over-year, in terms of social media channels for me. Why? What am I doing on Twitter that’s resonating?

    To answer this question, I’ve got to get Twtiter data. Right from the platform interface, I can export tweet-level data. What kinds of data?

    Twitter platform data

    While this spreadsheet is good – with all the major features like likes, retweets, impressions, etc. it’s not very good for understanding what’s working and what’s not. A big part of a social media strategy plan is understanding the content itself, and that’s not included in here (and never will be).

    What is included is the text of my tweets. Using basic text statistics, I can look for the words and phrases I use the most, then engineer new numeric fields based on those topics. For example, I’d count how many times I use the phrase "data science" or "social media".

    Once I have that information, it’s time to figure out if any of these metrics have a mathematical relationship to the outcome I care about, which in this case is clicks on the URLs in my tweets. Why? In order for someone to do business with my website, they need to get to my website. How do they do that? By clicking on links in the content I share that goes to my website.

    To build a model of what predicts my desired outcome, I use a machine learning technique called XGBoost to identify which participating variables have the strongest mathematical relationship to my target outcome, clicks. Bear in mind, I have to remove things like linear dependencies – metrics like engagements include clicks, so those variables shouldn’t be used in this kind of prediction. I also have to remove things like zero values – metrics which are always zero, like all the promoted tweets metrics (because I don’t promote my tweets).

    What’s the result?

    Twitter Channel Tactics

    Impressions is the greatest predictor of whether a tweet will get URL clicks, followed by retweets and detail expands. This is where domain expertise now comes into play. As a social media marketer, what things can you do to generate more impressions, more retweets, more detail expands?

    Impressions is pretty straightforward – you could pay to promote tweets. You could tag people in your tweet. You could use more popular or more niche hashtags. You could cross-promote your tweets on other social networks. You could include tweets in email marketing.

    Retweets would follow similar tactics, plus the very obvious asking people to retweet more important/valuable tweets.

    Detail expands is even easier – this feature isn’t available on tweets that don’t require it, like links and basic text tweets. Images and video do – so this would be encouragement to upload more media tweets.

    Is this the answer? Not quite. This is the testing plan, because regression analysis of any kind (which is what XGBoost is) only ever proves correlation and you learn in stats 101 that correlation is not causation. So the next step in our process would be to build a testing plan, testing each of these predictors – impressions, retweets, detail expands – individually and seeing if URL clicks increase. I’d set up a three week plan and tweet the same amount about the same topics, to the same audience, but with a focus on the tactics above for each of the predictors, one per week.

    After three weeks, I’d examine my results and identify whether or not the test was successful in generating more URL clicks than previously, and for the winning tactics, I’d now have a recipe for my social media strategy on that channel.

    Finally, I look at the analysis in terms of content and topics above. Why aren’t the topics I’ve identified a good predictor of URL clicks? Why aren’t people clicking on a specific topic more than others? The lack of predictive value for specific topics hints that I might not be sharing the kind of content my audience wants from me, so I should consider collecting data on a very common marketing topic and seeing what topics are most popular, then test that as well.

    Assemble the Final Plan

    After doing the above evaluation for as many channels as my attribution model suggested, I’ve got a social media strategy plan fully baked:

    • I’ve identified whether social media is working for me or not
    • I’ve identified what channels are working for me
    • I’ve identified what tactics on those channels get results
    • I’ve built a testing and action plan for those tactics to prove their effectiveness

    The final piece of the plan is something known as perturbation – introduction of randomness. One of the dangers of rigidly following a data-driven plan is over-optimizing, focusing only on what works with no testing of new things, even if those new things deliver less-than-great results. Anywhere from 5-20% of your marketing should always be perturbation, always be testing something new and different for a period of time to find out whether it’s appropriate or not.

    Perturbation testing could be within a set of tactics or channels, such as trying out Tiktok or Clubhouse, or it could be very granular, such as testing out new content or themes. Whatever it is, you always want to be testing new things to make sure you don’t miss the boat on an important sea change in your audience.

    So, that’s the data-driven answer on how to build a social media strategy plan. It will take time, resources, and expertise to put one together, but once you have it, you will stand behind it confidently.

    Shameless Plug

    If this sort of planning is something you’re interested in but you don’t have the time or knowledge base to do it, my company, Trust Insights, can build a data-driven social media strategy plan for you.

  • How To Diagnose Marketing Conversion Funnels

    How To Diagnose Marketing Conversion Funnels

    Shannon asks, "What can I do differently to increase my conversions between home page —> contact page —> contact forms filled out?"

    This is a more complicated question than you might initially think, because there are several factors at play here. Let’s think back to 1968 and Bob Stone’s direct marketing framework. In that framework, there are three key factors that yield conversions to sales (remembering that this is in the era of physical direct postal mail and the Internet wasn’t a thing):

    1. List
    2. Offer
    3. Creative

    Stone posited that most direct mail campaigns fail because of one or more failures in this process. Do you have the right mailing list, do you have the right offer, and do you have the right creative?

    Direct Website Marketing

    Fast forward 53 years and the same logic still works for our marketing. In the context of your website and improving conversions, we have to ask the same three questions, albeit slightly more abstract.

    1. Do we have the right audience? This is a critical question, especially as it relates to things like SEO. If the traffic coming to your website is interested in, say, marketing books and we’re selling coffee, it doesn’t matter how good your website is, how clever the design is, how many A/B tests you run. You will never increase conversions because you’ve got the wrong people on your site.
    2. Do we have the right offer? Are we selling what our audience wants to buy? If our audience is interested in coffee, and our coffee is twice the price and half the quality of our competitors, we’re not going to do very well. If our audience is interested in regular coffee and we’re selling decaf, we’re going to have an uphill battle. Our offer to our audience has to be competitive.
    3. Do we have the right creative? This is where user interface and user experience come into play. Does our website’s design, navigation, and customer experience help or hinder conversion? Do people get lost on our site? Do we distract them from the things we want them to do?

    How do we know if we’ve got the right audience, the right offer, the right creative? This is where analytics and marketing data science come into play.

    The Right Audience

    Determining whether we have the right audience is a blend of several different metrics. First, we determine where our traffic comes from. If it’s from a source that has audience data, like organic search or Facebook, we make the determination about our audience’s interests. Go into Facebook Page Insights or Google Search Console and see what your audience is interested in. What words or phrases do they find your site for?

    Search Console Query Results

    Are these search terms I want to be known for? Will this attract the right audience to my site? If this isn’t right, if this isn’t the audience I want, I need to change my demand generation strategies.

    The Right Offer

    There is no substitute for asking your audience what they want. I do this frequently, in things like email surveys, on-site surveys, etc. Every website owner should have a continuous survey in place asking users what they came for and whether they found what they were looking for. There is no analytical substitute for asking people what they want, why they’re at your place, and what you can help them with.

    If your audience is the correct one but they’re not responding to your current offers, then ask them what they would respond to, what they want. You will either find you need to change your offers, or change audiences (because your audience is in fact not the correct one if no one wants to buy what you have to sell).

    The Right Creative

    This is where tools like Google Optimize, Microsoft Clarity, and many others help us determine the user experience on our sites. What things do people respond to? What creative choices are working for or against us? We check things like Google Analytics Site Search data (assuming we have site search set up and turned on) to find out what people are searching for on our website. If critical, core offerings are being searched for, it means our navigation isn’t leading them there naturally.

    Microsoft Clarity
    Microsoft Clarity dashboard of UI issues

    This is where we do extensive A/B testing of layouts, text, images, the works – anything that affects the customer’s path to purchase. Running tests with a tool like the Trust Insights Most Valuable Pages assessment will help here.

    The Wrong Order

    Here’s where so many marketers go wrong: the order of operations. Too many marketers start with creative; they rush out and start doing A/B tests, they commission a website redesign, they hire a new product photography shoot. Creative is last in priority! Do the steps in order.

    If you have the wrong audience, nothing else matters. You won’t sell anything.

    If you have the right audience and the wrong offer, it doesn’t matter how your site looks – people still won’t buy.

    If you have the right audience and the right offer, only then do you need to fix up your creative and optimize it.

    Conclusion

    Fixing up a conversion funnel isn’t rocket surgery. The challenge is to identify what’s broken and fix it, in order of importance. Make sure you’ve attracted buyers, presented them with a compelling offer, and gotten out of the way of the purchase process as much as possible.

  • Can You Trust Historical Marketing Data?

    Can You Trust Historical Marketing Data?

    Shannon asks, "Are there identifiable website trends / metrics for speakers? I did some analysis on my website traffic for the last three years… can I trust the historical data and try to replicate it to increase my number of incoming leads?"

    As a fellow public speaker, you absolutely CANNOT build forecasts with any data about the speaking industry prior to the start of the pandemic. Period, end of story. Data from before the pandemic reflects a world, a reality that no longer exists. We are still in the middle of a pandemic, and speaking opportunities are radically different now. We’re on podcasts, we’re hosting digital events, we’re doing masterminds… anything except standing in front of a room of hundreds or thousands of people.

    This is going to be the situation still for months to come. At the time of this writing, many projections show the pandemic slowly receding around mid-year, barring any selection pressure which forces a mutation that evades vaccines and immune responses, thus prolonging the pandemic.

    Recent Marketing Data

    So, what does this mean for professional public speakers? It means the "digital only" era is going to stick around for a while. Probably by Q4 2021, barring those mutations, we’ll start to see hybrid events – a combination of digital and physical – emerge, and there will be a call for speakers to show up in person.

    In the meantime, we should be paying attention to recent data – data after April 1, 2020. That’s the data that reflects the world as it is. How different is that world? The number of people searching for keynote speakers is half of what it used to be at its peak before the pandemic.

    Keynote speaker searches

    Data sources: Google Trends and AHREFS. Chart shows average number of searches for keynote speaker terms by week for the past 5 years.

    In fact, when you look at just the 2021 data thus far compared to 2020, the number of searches is down 15.2% year-over-year – and that’s compounded on top of double-digit declines the previous two years. Now, is there seasonality to the search trends? Yes. There’s clearly a very seasonal, very cyclical ebb and flow to the search terms, a seasonality that you can still use to predict relative interest. But in terms of absolute interest, it’s been on the decline for years and the pandemic has only made that worse.

    If you were to extrapolate the current trends forward, you’d assume interest in keynote speakers would eventually go to zero. That’s not realistic, either. We don’t know what will happen with the events industry in the next two years, but whatever does happen, events will still need to have people presenting information at them in some fashion.

    What’s a Keynote Speaker to Do?

    If you’re in the speaking business, the time to diversify is now. Well, the time to diversify was a year ago, but there’s no time like the present. Search intent is down substantially, audiences have Zoom fatigue, and online events pay substantially less well than in-person events.

    What kinds of things should we be looking at? New books. Webinars. Podcasts. Subscription models. Masterminds. You name it – anything you can do to leverage the power of your brand and derive revenue directly from the audience, because events aren’t willing or able to pay as well as they used to – and even after the pandemic, it’s a big question mark whether fees will rise to pre-pandemic levels quickly or slowly.

    And get your vaccination as soon as you’re eligible. I foresee that it will be required by in-person events, at least to satisfy event insurance companies.

    The Lessons for All Marketers

    The most important lesson in all this is that your pre-pandemic data has to be taken with a large grain of salt for forecasting if your world has changed – which almost everyone’s has. Some businesses have flourished. Others have shuttered. No matter what your line of business, the fundamental changes in your audience have made pre-pandemic data unreliable for forecasting. Instead, be looking at recent data and discern your forecasts from that. Look for seasonality and cyclicality to provide a sense of when interest will ebb and flow, but glue your eyes to recent data, rather than looking at data from a world that’s gone.

    If you’ve been negatively impacted by the pandemic, diversify as much and as quickly as practical. The world we once knew isn’t coming back any time soon – and even when the pandemic is over, there will be large, permanent changes as a consequence. What those are, it’s too soon to tell, but we know they will be there.

  • Measuring Social Media Engagement

    Measuring Social Media Engagement

    Alexei asks, "What are the most essential steps to analyzing social media data with ‘engagement’ in mind?"

    The steps for measuring social media engagement are the same as any other digital marketing metric, and follow the 3 Whats:

    • What happened?
    • So what?
    • Now what?

    Let’s dig into each of these steps.

    Social Media Engagement: What Happened?

    Our first step in dealing with social media data has to be around extracting data to understand what happened. Based on the channels and platforms we’re dealing with, that could be as simple as exporting the data straight from our social platform’s analytics to as complex as having to write custom code to extract individual post-level data.

    For example, with a platform like Agorapulse, I can export all my engagement data as a simple CSV file for analysis. For this example, I’ll focus on Twitter, but this works for any channel managed in the platform:

    Agorapulse

    And to focus on a meaningful objective, let’s export traffic data to my website from Twitter as a source in Google Analytics:

    Google Analytics Twitter traffic

    We’ve now got the basic ingredients for doing our analysis. Let’s take a quick peek first:

    Simple line chart of Twitter engagement data

    We’ve got some messy but usable data here.

    Social Media Engagement: So What?

    Here’s the key question. We’ve got Twitter engagement data, and we see the different types of engagement. So what? Does engagement mean anything, or is it just a bunch of noise? The answer to this question is something we find with basic correlation analysis. We’ll benchmark all our engagement variables against site traffic from Twitter. Does anything I do with Twitter from an engagement perspective result in traffic to my site?

    Let’s take a look:

    Spearman correlation

    What we find, using a Spearman correlation, is that there are three variables that have weak but detectable correlations to Twitter traffic: replies made to me, replies I made, and brand mentions.

    The variables that we would expect to yield traffic – like new followers, or published links, or likes – don’t. None of these have a statistically significant correlation in this example to traffic from Twitter to my website.

    It’s important to point out that this is not the answer. This is a hypothesis we need to test, and it’s unique to my data. Your data will inevitably be different, so you can’t take this answer and run with it on your own Twitter account. You must run this analysis with your own data.

    Social Media Engagement: Now What?

    So we’ve answered the key "so what" question: does any of our engagement data matter? We know three variables do. The question we must ask next is, what do we do about it? Of those variables, I have control over only one of them. I can’t control how often people reply to me. I can’t control how often people mention me. But I can absolutely control how often I reply to people, how often I jump into relevant conversations and participate.

    If unpaid traffic from Twitter was a priority, then my answer to "now what" would be to develop a plan for fostering lots of engagement. Identify Twitter chats I could participate in and jump into those. Start following relevant hashtags and jump into those conversations. Find questions to answer. I’d do this for 30 days and then measure again – did I achieve the goal of more traffic to my site from Twitter?

    If the answer is yes, then I’ve established that there’s not only a correlation, but a causative effect between engagement and website traffic. I now have a battle plan I can move forward with.

    If the answer is no, then I’ve established that there isn’t a causal link, and I need to go back into my data and dig deeper for why.

    Engagement Might Not Mean Anything

    The value of this analysis is that it provides us with a direction to go, working towards a meaningful goal further down our marketing operations funnel. We have to be prepared for an answer we don’t like: all the social media engagement might not mean anything if it’s not generating business results, so be prepared for that possibility.

  • Working With Four Kinds of Marketing Data

    Working With Four Kinds of Marketing Data

    Katie and I were having a discussion recently about data, and one of the points she brought up in the discussion was that data is a very large umbrella term. We – especially me – tend to think of data in the context of marketing analytics as numbers, but there’s much more to it than that. The very words I’m typing right now are data.

    Why does this matter? As with anything, definition is vision. We look for what we know to look for – ask and ye shall receive, seek and ye shall find, as the expressions go. If I think of data only as numbers, then numbers are all I’ll be looking for. If we expand our definitions, we expand our vision.

    So, what does a bigger picture, a bigger definition of data look like? The trusty, venerable 2×2 matrix popped in my head while I was running, thinking about data in the context of analytics. We have subjective opinions, and we have objective facts. We have data that’s numbers, and data that’s not.

    The Data Types Matrix

    Objective quantitative data is pretty easy to understand. These are numbers like the number of people who visited our website yesterday. Straightforward, easy to work with, easy to process. Not a ton of depth, necessarily, because there’s no nuance. We’re use to working with this in analytics software.

    Objective qualitatitve data is also fairly easy to understand. In the world of analytics, these are your categories, your dimensions. They’re not numbers, but they’re still objective facts. The piece of content you’re reading now is text. The graph above is an image. There’s no number to assign to it, but these are still data types.

    Subjective qualitative data is a massive category. This is data that’s non-numeric, but subjective in how we interpret and understand it. It’s literature, experiences, rich media, emotions, tone of voice, sentiment, all the things that make us human. This is the data you get in interviews, surveys, focus groups – everything where we’re asking someone why they did what they did. One of the things that’s interesting about subjective qualitative data is that there are far fewer right or wrong answers. A piece of art will be beautiful to some people, ugly to others. A podcast may appeal to some audiences, while others will be wholly disinterested.

    Subjective quantitative data is an interesting category. It’s data that is numeric but based on opinion. There are some broad strokes here, from "alternative facts" where people not only interpret data differently but have their own data (regardless of credibility). Subjective quantitative data also appears more benignly in things like surveys and ratings. A product that has 4,800 5-star ratings on Amazon is quantitative data, but the data itself isn’t objective. The product may well and truly suck, or it may be completely amazing. Subjective quantitative data can also appear in the context of opinion about data; listen to any earnings call and you’ll hear CFOs give opinions and guesses about the financial outlook for a company. These are not facts, but they are numbers.

    Why does all this matter? If we’re in the business of data analytics (which my company is), and we’re in the business of making data useful, then we need systems and processes to work with the different kinds of data, especially when that data may be in unfamiliar formats. We also need an understanding of the different kinds of data and how they’re contained, so we know what to look for in the data. All data contains biases, but subjective data is likely to contain far more bias because it’s subjective by nature.

    Types of data also impact tooling and capabilities. Consider Instagram for a moment. Instagram posts contain multiple data formats: text for the description, which can be subjective or objective ("photo of my dog" vs "best dog in the world"), numbers for the levels of engagement, and objective data in the format of a video or photo. There’s a ton to unpack there; how many Instagram analytics tools unpack it all?

    Remember, definition is vision. What we understand defines the boundaries of what we’re looking for. Make sure you’re working with the scope of vision appropriate to the data you’re handling.

  • How to Measure and Analyze Dark Social Media

    How to Measure and Analyze Dark Social Media

    Stacey asks, "I’m so curious if you know of any proxies that work for estimating the value or volume of these "dark social" networks?"

    Measuring dark social media is obviously quite difficult since it’s by definition outside the scope of most tracking (hence dark). Depending on the urgency and importance, there are a few things you could do to estimate it and/or track it.

    Measure The Scope of the Problem

    First, let’s measure what we do know. How bad is the dark social problem? I’m going to assume you’re using some kind of web analytics software; I’ll be demonstrating with Google Analytics but these techniques should work with pretty much any package on the market that’s reputable.

    Any traffic that Google Analytics doesn’t know what to do with is bucketed under the source/medium combination of (direct) / (none). Direct traffic comes from three places:

    1. People just typing in your site URL.
    2. People visiting your site from bookmarks.
    3. People visiting your site from unknown places.

    Dark social media traffic fits in category three. So, how do we tell the difference? Direct traffic in category #1 will almost always be visits to the homepage. Let’s create a traffic segment in Google Analytics that encompasses all direct traffic, but excludes the homepage and any landing page we absolutely know to not be used in social media:

    Google Analytics Dark Traffic Segment

    Above, I’ve excluded the homepage and my newsletter unsubscribe page. What’s left is about 17.49% of all my traffic being unknown, which I’m quite happy about. If this were above 25%, I’d be mildly concerned. If this were above 50%, I’d be very concerned. If this were above 75%, I’d be extremely concerned that I’ve actually got an analytics infrastructure problem – and that any conclusions I was drawing from my analytics were wrong because we’d be getting into the territory of sampling errors.

    So, once we know how much dark social traffic we’re dealing with, how do we begin mitigating this?

    Track and Customize

    Our first step is to understand our audience. Ask people at every intake point in your marketing where they found out about you, from simple on-site questions to questions on forms, even to point of sale. Track that data carefully, look at it frequently, and start to understand where your audience spends their time.

    If you have an open-ended "How did you hear about us?" question and Slack comes up as the top channel, then you know a part of your dark social media traffic is probably coming from there. If it’s "my colleague texted me a link", then you know text is a channel potentially driving dark social traffic.

    There is no substitute for asking people. This is important; as good as analytics software is, you will never be able to rummage around in someone’s head.

    Join and Participate

    Once you’ve ascertained which channels may be driving dark social media traffic, start to dig into those channels. Say that 25 people all said on intake forms that Slack was how they heard about you. Follow up by email with each of them asking which Slack community they were in, and if the community is open to the public, join it and get the lay of the land. Who in the community shares your stuff?

    Slack example

    Here’s a simple example – I searched for the domain name of my site in the Analytics for Marketers Slack Community to see who was sharing my stuff. Obviously, I’m at the top of the list, but this is how you’d identify your champions within a community.

    Once you’ve gotten the lay of the land, as appropriate, share stuff yourself in the community using UTM tracking codes, as shown in the blue links above. This will reduce some of the dark social media traffic because you’re tagging your own stuff, and if your site/content is of interest to the community, you’ll beat others to the punch in sharing content – and your content will have sharing, whereas theirs will not.

    Detailed Analysis of Dark Traffic

    Finally, and this is more advanced, one of the things you’ll want to know is whether your direct dark traffic is truly dark social media traffic or not. Which traffic source does it behave like?

    Here’s an example over the past 10 months, looking at my dark trafic versus known social media traffic, known organic search traffic, and known email marketing traffic:

    Traffic source comparison

    What we’re looking for is correlation here – what does our dark traffic most closely resemble? Let’s run a Spearman correlation in the statistical software R:

    Spearman correlation

    Well, well, well. Look at the bottom row. Our direct dark traffic most closely resembles organic search traffic, with a Spearman coefficient of 0.54; 1.0 would be a perfect match, 0 would be absolutely no match, and -1 would be a perfect inverse relationship. We see that our direct dark traffic actually matches known social media traffic the least, with a coefficient of 0.25 – weak at best.

    This may mean that I have a dark search problem, rather than a dark social media problem! I’d want to dig in some more, start looking at individual source/mediums rather than channels as a whole, but this clearly indicates that the sharing behaviors in known social media just don’t match up as well with my mysterious dark traffic.

    Ask, Ask, Ask

    The ultimate solution to Stacey’s original question is asking people. There’s no substitute for it, because dark traffic by its very nature is dark – we have no data to rely on that we don’t actively solicit from our audience.

  • Understanding How Google Works for SEO

    Understanding how Google Works for SEO

    Mark writes in,

    "I am really struggling with the efficacy of search for most businesses. More than ever, the odds are stacked against us.

    1) Some search is leaking out through Siri + Alexa
    2) Most Google search (51%) is now "kept" by Google
    3) You’re irrelevant unless you are in the top 1-3 slots. That is simply not accessible for most businesses.

    For argument’s sake, let’s look at the hundreds of thousands of digital marketing freelancers out there. How many of them can rank in at least one term (or afford one) that can bring them meaningful business? While search, and your advice, is the heart of our profession I have a sinking feeling it becoming less relevant day by day."

    The idea that search is a monolithic entity where either you rank or don’t rank is only true for large enterprises challenging at the broadest levels. One of the wonderful things about machine learning and AI powering most search is that it’s now more granular and more context-driven than ever before.

    Searching for "coffee shop" on your desktop will give you different results than searching for the same phrase on your mobile device. Google in particular, but other search engines as well, understand that intent is different based on device. So, device type is one segmentation of several hundred applied to searches.

    Another example of how Google automatically creates niches is based on the intent type. "Coffee shop" and "coffee shop near me" are very different intents, even though they’re not semantically all that different. The latter is a location-based search.

    Google has hundreds, if not thousands, of niches where any company can do well in search, even competing on broad terms, if the company and the searcher are both in the same niche. You don’t have to rank in every niche, in every audience. You just have to rank well in the niches that matter to your business.

    So in Mark’s example, it’s a fool’s errand to rank for "digital marketing expert" or the like. But "digital marketing expert in San Diego real estate"? Or "digital marketing expert in SMB coffee shops"? That’s the place where you want to focus your efforts – context-rich searches.

    Mark is right in that Google keeps – and continues to grow – the overall share of search with new features like Passages. However, the absolute volume of search is also skyrocketing, so the volume of search a website earns is still increasing, as long as the SEO practitioner is keeping up with the times.

    The Real SEO Problem Marketers Face

    Therein lies the real challenge: keeping up with the times. Many marketers have incredibly outdated perspectives on SEO, ideas and concepts created years ago. Search engines have evolved incredibly just in the last two years – five year old SEO knowledge may as well be knowledge fished up with the Dead Sea scrolls. Moreover, using knowledge that’s outdated is not only ineffective, it may be actually harmful to your website.

    For example, two years ago, Google released a detailed paper on a new algorithm it deployed as part of search, called Deep Relevance Matching Models. This paper, which was later confirmed by Danny Sullivan as being applied to up to 30% of Google query results, is a huge game-changer for how we think about optimizing our content:

    Deep Relvance Matching Models

    What made this revelation a game-changer is how Google sees our sites. For years, search practitioners have been locked in the idea of keywords, keywords, keywords. Over the years, Google’s AI capabilities have increased its scope of understanding from the word to the phrase to the paragraph to the document – and that’s what DRMM understands and informs, queries and results at the document level. Your whole page as a coherent work matters, not just a single phrase.

    The funny thing is, Google telegraphs a lot of this information very publicly. They make their research papers publicly available and free to read. They talk about their architecture and systems on blogs, YouTube channels, social media, and podcasts – and even provide helpful transcripts. They tell us the training data they use to build their models, the Search Quality Rating Guidelines. They lay out the buffet and invite us to dine at it with them.

    And what do many marketers do? They stand at the massive, free buffet and eat only the croutons, because the buffet looks intimidating – and instead of rolling up our sleeves and teaching ourselves how AI and machine learning, we shy away and criticize Google instead, or bluff and pretend we know what we’re talking about. Neither is a good strategy when you’re competing with an AI.

    Search is more relevant and more powerful than ever if you know what you’re doing, if you know how the systems work and how to work with them, not against them.

    So, that’s the challenge facing many marketers. Take the time to skill up your knowledge of how Google works today, not the historical snapshot trapped in many people’s minds, or hire an agency that knows what it’s doing.

    An easy way to screen SEO professionals and agencies is to ask them to explain two or three of Google’s neural network-based models and how they impact search, like DRMM, BERT, and TF-Ranking. If, in a casual conversation, they express absolutely no idea what any of these things are, you’re dealing with someone whose knowledge is out of date.

    Ask them to explain how Google indexes content from a mechanical perspective. Google has outlined this process in detail – and given tactical advice for how to adapt your SEO practices. If the answer seems like a bunch of nonsense instead of details about Google’s Chrome server farm, you’ve got someone with out of date knowledge.

    Where to Learn More

    Finally, keep in mind this one maxim: Google is optimizing for the human at the end of the search query. It’s not optimizing for us, the marketer. We have to optimize to the same objective – and you don’t need a billion dollars of technology at the end of it. You need to understand the human. Trust Insights has a new paper out today, in collaboration with our partner Talkwalker, on informing modern SEO with social media data. Give it a read; it’ll show you how to take practical steps towards optimizing for humans and give you more depth on a lot of the AI talk in this post.

  • How to Calculate Diminishing Returns

    How to Calculate Diminishing Returns

    I had a fun debate with my kids recently about the Mega Millions lottery and at what point you hit diminishing returns on purchasing lottery tickets. Lottery tickets are inherently a bad mathematical bet; the ROI of many games is somewhere around -90%. For every 1 you spend on the lottery, you lose0.90 of it.

    That said, there is a very tiny case to be made that the purchase of a few tickets for an especially large prize is relatively harmless fun, as long as you don’t need the money for something else. Arguably, if you spent 5 on the lottery versus5 on candy, the lottery would technically be the healthier choice. While the odds of you winning the lottery are astronomically small, the odds of you winning with no tickets purchased is definitively zero.

    How small? For the current iteration of the Mega Millions lottery, the probability of choosing the winning combination of numbers is 1 chance in 302,575,350. For context, the probability of you being hit by lightning twice in your lifetime is 1 chance in 100,000,000, so you’re three times as likely to be struck by lightning twice as you are to win this particular lottery.

    Calculating Diminshing Returns Exercise

    With the understanding that your chances of winning are incredibly small comes the realization that increased numbers of tickets do technically cut your odds. But at what point is buying more tickets an exercise in futility? This is an exercise in calculating diminishing returns, and for this, we’ll need to dust off our knowledge of derivatives. Let’s start with the basics and lay out the odds.

    Example Diminishing Returns Table

    We see our total odds of winning shown in column B in the chart above, and the number of tickets purchased in column A. Column C, outlined in red, shows what the odds are for any given number of ticket purchases.

    1 ticket purchased is 1 chance in 302,575,350.

    2 tickets purchased is 1 chance in 151,287,675. That’s a significant change between the two, cutting the odds in half. That’s what started this whole line of questioning from my kids – if 2 tickets cuts your odds in half, more is better, right?

    To understand how quickly that becomes futile, column D, highlighted in yellow, is the difference between the previous rows in column C, straight division of the current cell by the previous cell in column C. We see that when you buy two tickets, you cut the odds by 50%. When you buy three tickets, you cut the overall odds by 66.67% – you started with 1 chance in 302,575,350, and now you’re at 1 chance in 100,858,450. You’re still more likely to be struck by lightning twice in your life, but the odds are better. We can visualize that trend with the blue bar chart.

    To understand what’s happening, we look at the difference in change rate, shown in green in column E. This is a (new – old) / old calculation. Cutting our odds by 50% for 2 tickets but 66% for 3 tickets represents a 33% change in improving our odds. When we buy 4 tickets, that percentage change drops to 13%. When we buy 5 tickets, that drops again to 7%.

    Pay attention to what happens after the 15th ticket. Our percentage change in improving our odds is effectively zero (it’s a rounding error at that point). At that point, every additional ticket purchase doesn’t really change our odds at all. So mathematically for this particular lottery, there would be no sense in buying any more than 16 tickets ever. We see this reflected in the blue bar chart – it basically levels off after the 16th ticket.

    Incidentially, these are still astronomically high odds. 1 chance in 18,910,959 (the odds at 16 tickets) is still 10 times higher than the probability of you being struck and killed by lightning, which is estimated at 1 in 180,746 annually. So you’re 10 times more likely to die being struck by lightning on the way to purchase your 16 lottery tickets than you are to actually win the lottery.

    Practical Applications of Calculating Diminishing Returns

    Now, this exercise is a fun way to teach kids about probability and diminshing returns, and emphasize that the math is firmly, firmly against you. Is there a chance you’ll win? Yes. Is it a reasonable chance? Absolutely not. But how else might we use this mathematical exploration?

    Diminishing returns is something overlooked when we spend money on anything. In business and marketing, some of us operate on the same naive principle that throwing more money at a problem will solve it, without looking for diminishing returns. If you were to assemble your data and examine it, you might find the same trend – at a certain point, adding more money just doesn’t yield the same returns. They diminish, and your costs go up. You might have seen massive growth in a tactic early on, but as you reached more and more of that audience, your costs go up disproportionate to the results you’re getting.

    Here’s an example from a recent campaign:

    Diminishing returns in an ads campaign

    I compared the rate of change in spend versus the rate of change in conversions; after about the 15th day of this campaign, the rate of change in conversions no longer outpaced the rate of change in spend. At that point, it was a linear trend – put $X in, get Y conversions. That worked for this campaign. If we had hit serious diminishing returns, the blue bars would go below the 0 line, where the rate of change of spending was increasing faster than the rate of change of conversions – and it’s at that point we’d need to hit the brakes.

    What’s important about these calculations is that absolutely none of the advertising services provide this analysis to you. Not a single one will ever say, "hey, it looks like your performance is experiencing diminishing returns." Why would they? Once you know you’re hitting diminishing returns, the logical thing to do is to stop spending as much money. Thus, you must perform these calculations on your own.

    There are mathematical techniques and software that can do these sorts of things; to get into the hardcore stuff will require you to dust off your calculus books and refresh your skills on computing derivatives (or have beers with a colleague who remembers it better), but the benefit of those skills is saving yourself substantial amounts of money and headaches.

  • Google Analytics 4 Traffic Types by Stream

    Google Analytics 4 Traffic Types by Stream

    Guilherme asks, "Can I ask you something about platform type? I ran facebook ads to my website, shouldn’t my traffic be split between the 3 types fo platform (web, android and ios)? I only got Web…"

    There’s a bit of a mixup here. Let’s dig into some of the nomenclature of Google Analytics 4 to clear things up.

    Google Analytics 4 Data Streams

    Google Analytics 4 supports 3 different types of data streams as inputs into the application – web, Android, and iOS. These are not outputs, meaning that you would analyze each separately. These are inputs.

    The purpose of data streams is to bring in data from different application types into a single Google Analytics 4 account for analysis. You wouldn’t perform analysis on the different data stream types, nor would Facebook ads sending traffic to your web property show up in your iOS or Android streams.

    Google Analytics 4 Inputs and Outputs

    So if you don’t analyze by data stream, where do you analyze? By the outputs.

    Google Analytics 4 Analysis Hub

    To understand how your ads performed on the different devices, you’d instead build an analysis using operating system in the comparison tool. For example, I’ve created a three way split of my traffic here for iOS, Android, and the desktop operating systems, just in the regular Traffic Acquisition canned report:

    Google Analytics 4 Traffic OS Comparison

    And of course, you could slice and dice that any number of ways; the preferred way to run that kind of analysis is in the Google Analytics 4 Analysis Hub. Analysis Hub is a far more flexible way to dig into your GA4 data, as well as save previous analyses for future re-use.

    Google Analytics 4 Analysis Hub

    Above, I’ve set up a dimension for Operating System, a second dimension for Session Campaign, and a filter for the Session Campaign; since I don’t run Facebook Ads, I specified my newsletter instead. Now I’m able to slice and dice to see how much traffic I got to my website from my newsletter, by operating system.

    If this is just ad hoc analysis to answer a specific question, then Google Analytics 4 is the place to do this. However, if this is something you want to be able to report on regularly and frequently, Google intends for you to do that elsewhere.

    Google Analytics 4 Reporting is in Google Data Studio

    The old Google Analytics was built as a Swiss army knife of sorts – data collection, analysis, and reporting rolled into one application. The new Google Analytics 4 is not designed for this – it’s a true analysis tool, which means things like reporting and visualization aren’t done in GA4. They’re intended to be done in Google Data Studio:

    Google Analytics 4 Report by OS and Source

    Above, I’ve created an overly simple pivot table with operating system and the acquired source of my newsletter; you can just as easily put in medium or campaign to get the same reporting. If you need a canned report, especially for presenting to stakeholders, this is the way you’d do it.
