Third Party Cookies and Attribution Models
Mabelly asks, “Whenever I think about attribution model, a question pop up. How we should deal with “the end of the 3rd party cookies”? How do you guys address this issue?”

Third party cookies (or the lack thereof) and attribution models are two entirely separate things. So we’re talking about the same thing, let’s set some baselines and definitions.

What is a Cookie?

A cookie, simply put, is a tiny text file stored inside your web browser or device apps that contains identifying information about you. Here’s an example of a Google Analytics cookie:

You can see there isn’t a ton in here; the main thing that makes this valuable is the second line. That’s an anonymous ID Google has assigned to me personally that tracks me on my own website. When I show up on ChristopherSPenn.com, Google Analytics looks for the _ga cookie and when it finds it, it loads my ID number into Google Analytics, which then helps it understand that I’m not a new user.

Third Party Cookies

Here’s a quick explanation of the different kinds of cookies, since you’ll often hear about first and third party cookies.

A first party cookie is set by a site and the data is sent back to that site. When you visit my blog, my website sets a cookie for ChristopherSPenn.com on your device that stores things like your preferences or what ads from my site I’ve shown you. Everything is owned by me, and that’s what makes it first party.

A second party cookie is set by a site you don’t own, but it’s your cookie, your tracking code. An example of this would be someone visiting a partner site, like MarketingOverCoffee.com or TrustInsights.ai, and that site setting a cookie for ChristopherSPenn.com on it. It’s still my cookie, and if you come back to my site, I’ll know you were on those other sites based on the cookie data. These are relatively rare except in networks of sites, because it requires the site owners both grant permissions to each other to distribute multiple sets of cookies.

A third party cookie is set by a site you don’t own, and that cookie tracks behavior across a whole bunch of different sites, including sites the cookie setter doesn’t own. In the example above, the ad network, C, is allowed to implant its cookies on site D, even though it doesn’t own site D. People who visit site D get ad network C’s cookies. When they go to visit other sites with the same ad network, like site E or F, those sites tell ad networkC that the user has visited them.

Here’s the critical difference about third party cookies. Let’s say we’re site A. When we buy ads from ad network C, we are buying data they collected about users on sites D, E, and F, even if we have no connection to those sites. That’s what makes them third party: we are buying from C, but the users on sites D, E, and F didn’t consent to us getting any information about them, nor do they necessarily even know who we are. They may or may not ever have been to our site, site A.

What’s Going Away

It’s this latter relationship that companies who are ending third party cookie support are breaking intentionally. Ad network C will no longer be allowed to track its cookies on sites, D, E, and F, and won’t know if users have been to those sites. Second party cookies also will likely break but again, they’re not all that common.

What won’t break is the first relationship. We’ll still be able to put and read cookies from our site with our audiences, so things like Google Analytics will continue to work. Why? Google Analytics is always integrated into our websites, so someone on Site A will get a GA cookie from A, and GA has the rights and privileges to read that cookie because we’ve given it permission.

What Does This Mean for Attribution?

To get back to the original question, the change in third party cookies will not impact attribution at all.

Why, given it will have such an outsized impact in advertising?

From a data perspective, attribution and advertising are completely separate entities. Advertising sends traffic to your site. It’s a source of traffic. Attribution modeling helps you understand where your traffic came from and whether it did what you wanted it to do or not. Even if ad networks lost 100% of their tracking capabilities, you will still know they’re sending you traffic, and you will still know whether that traffic is converting or not.

What the end of third party cookies is likely to do is change the quality of your advertising traffic, probably for the worse, but it’s not going to change what kind of attribution you do or how you’ll interpret the results.

So, what should you do about all this? First, plan for diminishing quality of ad traffic in general; the only ad network I see not particularly affected by everything is Google Ads. Why? They own:
- Google search, which tells them what we’re looking for
- Android, the mobile operating system powering something like 70% of the world’s devices
- Chrome, the browser with 60+% market share
- GMail, one of the top email providers
- YouTube, the most popular video site on the planet
- Google Analytics, the most popular web analytics software that millions of websites have voluntarily implemented
- Google Suite, office software for thousands of businesses
- Google Home, thousands devices we voluntarily set up in our homes
In other words, it’s fairly safe to say Google doesn’t need cookies to track what we’re doing, nor to target its ads.

That said, you should be looking at your attribution models frequently, and comparing them month over month. Look for what’s changing and especially what’s diminishing in effectiveness. That will tell you a great deal about whether tracking changes are impacting your upstream traffic providers.

At the same time, you should be building first party audiences like crazy. Email lists, SMS lists, private social networks like Slack and Discord – you name it, as long as you control it, you should be building there and focusing your time, effort, and budget on those places you control.

The Bottom Line

Third party cookie tracking loss is only the tip of the iceberg as far as what’s going to happen with customer privacy over the next few years. The only surefire, long-term strategy that will be timeless and effective is to have customers voluntarily give us information with full, informed consent. That will never go out of style or get blocked by legislation or technology.

How Often Should We Change Attribution Models?
Andrea asks, “How often are you changing your attribution modeling vs the change in organizational strategy?”

An attribution model is something that’s mapped fundamentally to your sales and marketing strategy. It should change as you change strategy, or as your audience changes.

First, let’s establish a baseline. Why do we need attribution models? Fundamentally, attribution (from Latin, ad tribuere, to give to) is about understanding and giving credit to different marketing channels and tactics based on their contributions to achieving your goals.

We need attribution models to understand how different channels generate results. The more touchpoints involved, the more we need a more complex attribution model. Here’s an example from my Google Analytics that tells me the average number of touchpoints before conversion:

We see above that the majority of my conversions occur within one touchpoint, 83%.

A last-touch attribution model is appropriate for companies that are almost purely transactional in nature, with very fast sales cycles and few touchpoints. An ecommerce company selling a SaaS subscription where the visitor comes to the site and buys something, then leaves would be an example. There’s no interaction, no content to read, no relationship with the customer. They come in, do the thing, and get out. That’s a great candidate for a last-touch model.

Generally speaking, if a site accomplishes its conversions in one touch 95% of the time or more, a last-touch model is fine.

Suppose you changed marketing strategies and started to pursue more of a content marketing strategy. You want to attract visitors through organic search, through social media, and you want to build an actual relationship with them. At that point, you’d probably want to change models to something like time decay or a true multi-touch attribution model, because you’d start to have more complex interactions with your audience.

For example, my site went from ~90% of conversions being one touch to 83% over the last couple of years. Once I dropped below 90%, I had to change attribution models to deal with the increasingly complex ways audiences were finding me.

The other rule of thumb I go by is how many marketing channels are involved. If you’ve got a company where you run only Google Ads and that’s literally how you make all your money and nothing else, then you can use a first or last touch model with no reservations. Arguably, you don’t need an attribution model at all, because you’re only doing one thing and it’s working. Once you get above three channels and you need to understand the interactions of those channels with each other, then you should be looking at changing attribution models to accommodate the greater complexity.

Why do we care? We care because we want to know what’s working, and in proportion to the resources we allocate to our efforts. It’s good to know, for example, that Google Ads drove 25% of your conversions, but it’d be more important to ascertain what percentage of your hard and soft dollar budget you expended. If you spent 10% of your budget and got 25% of your conversions, then there’s a clear sign to spend some more. On the other hand, if you spent 50% of your budget to get 25% of your conversions, that channel might not be pulling its weight.

The reason we use more complicated attribution models is to take into account things like brand awareness, etc. that individual tactics may boost, but aren’t the last thing a prospective customer did prior to converting. Some channels simply work better at the beginning of a customer journey than at the end; with the correct attribution model, we’ll ascertain what those are and make sure we’re using each channel to its maximum effect.

To wrap up, change models when your strategy or your audience behaviors change, and match the model you choose to the complexity of your channel mix.

Why You Need to Understand Marketing Machine Learning Models
One of the technical marketing hurdles I hear marketers struggling with on a regular basis is the idea of an algorithm. Marketers talk about Google’s algorithm, Facebook’s algorithm, Instagram’s algorithm, and this bit of language matters a great deal in our understanding of what’s going on behind the scenes with big tech and marketing.

To clarify, an algorithm is a process with a predictable outcome. Any time you pull out a cookbook, follow the instructions for a recipe, and cook the dish more or less as it’s described and depicted, you’ve used an algorithm.

That is not what Facebook et. al. use when they serve us content and ads. It’s not a single monolithic process, but a complex mixture of processes and data to create their desired outcome (which is ad revenue). When we talk about machine learning and AI in this context, these companies don’t have algorithms. They have models.

Machine Learning Models Explained

A machine learning model – from the most basic linear regression to the most complex multi-task unified model – is essentially a piece of software. The difference between regular software and machine learning software is mainly in who wrote it – machine learning software is written in part or in whole by machines. Google’s search AI? That’s a model (it’s actually a collection of models, but that’s a story for another time). With Instagram’s slightly more transparent explanation of how its feed works, we see that it too is comprised of a sophisticated model with many different pieces. Here’s what head of Instagram Adam Mosseri had to say recently on a now-deleted blog post:

We start by defining the set of things we plan to rank in the first place. With Feed and with Stories this is relatively simple; it’s all the recent posts shared by the people you follow. There are a few exceptions, like ads, but the vast majority of what you see is shared by those you follow.

Next we take all the information we have about what was posted, the people who made those posts, and your preferences. We call these “signals”, and there are thousands of them. They include everything from what time a post was shared to whether you’re using a phone or the web to how often you like videos. The most important signals across Feed and Stories, roughly in order of importance, are:

Information about the post. These are signals both about how popular a post is – think how many people have liked it – and more mundane information about the content itself, like when it was posted, how long it is if it’s a video, and what location, if any, was attached to it.

Information about the person who posted. This helps us get a sense for how interesting the person might be to you, and includes signals like how many times people have interacted with that person in the past few weeks.

Your activity. This helps us understand what you might be interested in and includes signals such as how many posts you’ve liked.

Your history of interacting with someone. This gives us a sense of how interested you are generally in seeing posts from a particular person. An example is whether or not you comment on each other’s posts.

From there we make a set of predictions. These are educated guesses at how likely you are to interact with a post in different ways. There are roughly a dozen of these. In Feed, the five interactions we look at most closely are how likely you are to spend a few seconds on a post, comment on it, like it, save it, and tap on the profile photo. The more likely you are to take an action, and the more heavily we weigh that action, the higher up you’ll see the post. We add and remove signals and predictions over time, working to get better at surfacing what you’re interested in.

In his language, he clearly describes the basics of the machine learning models that power Instagram, the inputs to those models, and the expected outcomes. That’s essentially an explainability model for Instagram.

Why Understanding Machine Learning Models Matter to Marketers

So what does this all mean? Why does this matter? When we think about machine learning models, we recognize that they are essentially opaque pieces of machinery. We, as marketers, have little to no control or even oversight into what’s inside the models or how they work. Frankly, neither do the companies who make them; they control the means by which the models are assembled, but they’re so complex now that no one person understands exactly what’s inside the box.

To put this in a more understandable context, what do all the pieces inside your blender do? We know the basics – electricity activates magnets which turn gears which make the blender go – but beyond that, if someone put a pile of modern blender parts in front of us, the chances of any of us reassembling it correctly are pretty much zero.

But we don’t need to, right? We need to know what it does, and then the important parts are what we put in the blender, and what comes out of it. If we put in sand and random plant leaves, we’re not going to have a particularly tasty outcome.

Machine learning models are just like that: what we put into them dictates what comes out of them. In Mosseri’s post above, he calls the inputs signals – essentially, data that goes into Instagram’s model, with the outcome being a feed that keeps people engaged more (and thus showing them more ads).

Which means that the only thing we have control over as marketers in this scenario is what goes into our audience’s machine learning models. We can do this by one of three ways:
1. Create such amazingly great content that people desperately want to see everything we share. They mark us as Close Friends in Instagram, or See This Person First in Facebook, or hit the notifications bell on YouTube, etc.
2. Buy ads to show our stuff to our audience more frequently. This is what the tech companies are aiming to optimize for.
3. Divert attention through external means to our content on the algorithm we want to influence most.
Point 1 is table stakes. If your content isn’t good, none of the rest of this matters. Get that right first.

The real question comes down to 2 and 3; I lean towards 3 because it tends to cost less money. By using external platforms to influence what ingredients go into the various machine learning models’ inputs, I can change what comes out the other side.

If I put even one strawberry in a blender with other ingredients, everything will come out with at least a bit of strawberry flavor. If I can get my audience to at least one piece of content that’s seen by machine learning models, then I change the signals that model receives, and in turn I influence that model to show more of my stuff to my audience.

How do you do that? Here’s an actual example. I featured a video recently in my newsletters, which many of you watched:

“>

What does that do to YouTube’s recommendation engine? It looks at watch history, watch time, etc. and then recommends things you might also like that are in a similar vein. This in turn means that other videos on the channel get recommended more often to people who have watched the one I shared. What does that look like?

At point 1, we see the baseline of all video views on the channel before I started these tests.

At point 2, we see the video I published and promoted heavily in newsletters.

At point 3, we see a new baseline established for all video views.

By using an external mechanism to promote the video, I changed – briefly – the inputs into YouTube’s recommendation engine for all the people who watched the video. If I sustain this process, I should see the channel’s videos do better and better over time, including videos I haven’t shared or promoted.

That’s how we change the inputs to machine learning models, by using external promotion mechanisms. We can of course do this with advertising as well, but if we have the assets and capabilities to promote using lower cost methods, we should do those first.

Where should you do this? On any channel where you care about the performance. I don’t do this on Facebook, for example, because I don’t particularly care about the channel and engagement there is so low for unpaid social media content that it’s a waste of attention to send people there. YouTube’s performance for me has been substantially better over last year or so, so I direct attention there. Decide which channels matter most to your marketing, and use this technique to alter what the recommendation engines show your audience.

How People Quitting Jobs Impacts Your Marketing
One of the most challenging things to tackle is any news headline where the source data isn’t provided. This was the news blurb from LinkedIn:

“Predictions of a “Great Resignation” appear to be coming to pass, with the share of workers leaving jobs at 2.7% in April — the highest level in more than 20 years, says The Wall Street Journal, citing U.S. Labor Department data. The elevated quit rate is a stark contrast to a year ago, when workers were focused on job security during the pandemic. Economists say employee churn is a sign of a healthy labor market and higher worker confidence as people leave for better prospects, even during a still-shaky economic recovery.”

I immediately had questions. I don’t doubt that the topline number is correct, but the real question is, what are the sector movements, and what could they mean for business?

What Does the Data Say?

To dig deeper, we turn to the actual Bureau of Labor Statistics data, helpfully collated by the St. Louis Federal Reserve Bank’s FRED database. Here’s what we see in 2021:

Figure 1. Job quits; numbers are in thousands of people

On an absolute basis, trade, transportaion, and utilities – i.e. people moving stuff around – saw the greatest quits this year so far. Leisure and hospitality came in second, and professional and business services came in third for total number of people; food services came in fourth and hospitality came in fifth.

Why? What’s going on that these sectors are seeing such large numbers of people quitting? The short answer is that all these sectors have been under substantial strain during the pandemic:
- Trade and transportation has been under duress the entire pandemic, and the logistics failures in our supply chains have not made those jobs better.
- Hospitality, food services, and retail are all sectors in which employees have long faced low wages and punishing working conditions, made worse by the general public’s misbehavior.
- And professional services has seen a spike as companies have reopened offices and insisted employees return to physical offices, which in turn has made some employees simply quit.
So What?

Hiring and training new employees is expensive. Any time an employee quits, regardless of the level of position, you lose some institutional knowledge. That’s not necessarily always bad – “this is the way we’ve always done it” is an attitude that tends to harm more companies than it helps. But help or harm, changing out personnel is costly and time-consuming.

As a result, expect businesses in the most affected sectors to have higher costs than normal and for a short period of time, reduced productivity. Those companies which have strong, established processes for onboarding and training new employees will fare the best; those who struggle to codify institutional knowledge will feel a greater impact.

From a marketing perspective, keep an eye on the industries with the highest churn. If you do any kind of list-based marketing in those industries, accept that like last year, your list is going to churn more. Your email database will decay faster, your CRM contacts will fall out of date faster. That means you’ll need to work harder to acquire new audiences to replace the audiences you’ve lost, especially if those people are vacating your industry sector entirely.

Especially if you’re in B2B marketing, end the practice of requiring work-only email addresses (i.e. prohibiting people from using Gmail, Hotmail, etc. addresses). Doing so means you lose contact with valuable people the moment they leave their jobs.

From a content marketing perspective, after this new wave of pandemic hiring and quitting recedes, expect a surge in demand for introductory-level content and training as all the new people struggle to get up to speed. While there’s always a background demand for the basics, any time you have a big wave of new hires, there’s always an increased demand for the basics.

Use Economic Data to Plan Marketing

This data, like so much macroeconomic data, is yours for the taking, paid for by the American taxpayer. Use it to your advantage, to plan your marketing, to understand what your audience is likely to do and what challenges they face. Like a gold mine that no one has ever excavated, you sit on data that you could be using. Start digging!

Measuring the Financial Impact of Earned Media
Shea asks, “Wondering your perspective on how to measure the financial impact of earned media when it doesn’t include a backlink to the company website?”

This is a fairly common question. There are several ways to peck away at this and arrive at a conclusion that’s on reasonably solid ground. Let’s dig into those methods.

Analytical Calibration

The first thing we need to understand are the values of our digital channels. To do this, you need a robust attribution model, based on reliable software like Google Analytics. In that software, you need to have goals and goal values set up; goal values confer a dollar value on the activities inside Google Analytics.

Why do we need this? Activities like earned media show up in other ways. Rarely, it’s direct traffic; more often than not, it’s through things like organic search or referral traffic. In the case of Shea’s question, it’s very likely to be organic search. With a good attribution model, we’ll be able to infer the value of an organic search visitor.

The second calibration step we’ll need, besides ensuring goal values, is to ask people how they heard about us in our customer touchpoints. This question helps reveal some of the precursors to organic search. Ideally, if we had a successful earned media campaign and someone read about us in, say, Fast Company, they would put “Read about you in Fast Company” as their reason.

You can see a more detailed example of this calibration step in this blog post.

This calibration step alone can help understand the impact of good earned media campaigns. Keep track of the number of times someone responds with things like “I saw you on…” or “I read an article…” and you’ll begin to pick out where those offline or disconnected interactions occur the most. You’ll also gain more insight into connected channels that may not be yours; for example, if an influencer talks about you in their Slack or Discord community, you likely would never know until a customer mentions it.

Modeling Earned Media Lift

Because there’s no way to do an A/B test (the preferred method usually) for seeing the impact of a campaign, we have to resort to statistical techniques that essentially reconstruct A/B tests retroactively.

Why? Rarely do any campaigns ever operate in a vacuum. At the same time that an earned media campaign is occurring, chances are many other things are happening as well – search ads running, email campaigns going out, Instagram ads running, etc. a customer will likely be impacted by many different methods of communication, so we have to essentially remove the effects of other marketing methods to see what impact our earned media campaign had.

If we don’t do this, then we run the risk of attributing impacts to the wrong things. For example, suppose at the same time an earned media campaign was occurring, a new Google Ads branding campaign was running. Which deserves credit for a boost in traffic and conversions?

The best practice in this case, for those companies with a sufficiently robust CRM, is to track and log every touchpoint a prospective customer has – including those “how did you hear about us” responses – and then build either a propensity scoring model or a binary classification model based on that information. We specify those people who responded with earned media campaigns as the “treatment” group, and everyone else as the control group, then analyze the likelihood of someone converting based on that “treatment”. This requires access to machine learning tools, be they free like R or paid like IBM Watson Studio.

For companies that don’t have that level of data, we can still use propensity score models in a lower accuracy version. Instead of tracking individuals, we track the days and times our earned media campaign has run, and then measure against similar days when earned media campaigns weren’t running (our control data). As with the best practice version, this creates a “treatment” of our marketing with earned media while removing some of the noise of other channels.

Let’s look at a practical example. Few would argue that having company executives on stage would be earned media, especially if you didn’t pay to have them there. Using the propensity score model on a day-level basis, here’s what the difference was in terms of my website traffic by source between the days I was speaking (and the three days following) versus other similar time periods:

Of the channels, I consistently see more traffic from LinkedIn on days when I’m speaking compared to days when I’m not speaking. That makes intuitive sense as well as analytical sense; people who are watching me speak are likely checking out who I am as well.

Putting Together the Financial Impact

Using this model, we can ascertain the exact number of visitors to our site from different sources – and the delta, the difference, for earned media campaigns. In my case, I earned 2.4x more visitors from LinkedIn during periods when I was speaking compared to periods when I was not. If I extract the actual data, the actual number of users, I can find the delta between those two. Again, from the example above, that was something like 125 users’ difference on speaking days compared to non-speaking days.

In other words, earned media got me 125 visitors more during those time periods than not.

This is where our Google Analytics goal values come into play. If we’re able to extract the average monetary value of users from each given channel, then we multiply that value times the difference, the delta, of earned media. In the example above, if LinkedIn users are worth, say, $10 on average, and I have a model that shows I got 125 more users from LinkedIn because of my earned media, I can infer the value of those users at$ 1,250 – and that’s the value of earned media in this example.

That’s one of the ways we can determine the value of any channel.

When This Won’t Work

There are situations where this methodology doesn’t work, especially for the time-based model, which I showed above. Propensity score modeling in particular requires there to be enough control data to find good matches with the treatment data, usually 2x more control data than treatment data.

That means if you’re running “always on” campaigns, you won’t be able to measure their impact because there will be no “off” days to compare them to.

The best way to do this is at the individual level; the aggregated level does work but it’s not nearly as accurate.

This method also doesn’t work if there are two synchronous campaigns; if an earned media campaign always occurs at the exact same times as a different campaign, disambiguating between the two is not possible. You see this happen most often during things like major product launches where everyone’s going full steam on everything all at once.

Conclusion

There is nothing in marketing that cannot be measured. The question always boils down to, how much is your organization willing to invest in time, money, and resources to conduct the level of measurement that you want to achieve? Market research and data science paired together can achieve very high levels of confidence, but at high costs (though not as high as wasting budget on things that don’t work).

When someone says something in marketing can’t be measured, what they’re really saying is they’re unwilling to make the commensurate investment to measure the thing. Earned media is one of those areas where people seem perennially unwilling to invest in measurement, even though proven methods for measuring earned media have existed for years. The techniques outlined above are just newer additions to an already robust toolkit.

One Step Closer to the Marketing Singularity
We’re one small step closer to the marketing singularity, the event where machines become our first choice for doing marketing work. Ever since OpenAI’s announcement of GPT-3 (and the relatively heavy restrictions on it), a number of other organizations have been working to make alternative models and software available that have similar performance.

As background, GPT-3 is the latest in the family of transformers, machine learning models that can generate text and perform exceptional recognition of language. These models are large and very computationally-intensive, but they’re also generating text content at quality levels approaching human. GPT stands for Generative Pre-trained Transformer, and they’re becoming more accessible and powerful every day.

Let’s look at an example, using EleutherAI’s GPT-J-6B model. Let’s take a relatively low-value marketing task like the drafting of a press release. I’ll use this release from a plumbing company:

With the text shown on screen only, I fed it to GPT-J-6B. Let’s see what it came up with:

And for comparison, here’s the rest of the original release:

I would argue that what the machine synthesized is easier to read, more informative, and generally better than what the original release presented. More and more AI-based tools will hit the market in some form that are at least “first draft” quality, if not final draft quality. We’ve seen a massive explosion in the capabilities of these tools over the last few years, and there’s no reason to think that pace will slow down.

So, what does this mean for us as marketers?

I’ve said for a while that we are moving away from being musicians to being conductors of the orchestra. As more easy and low-value tasks are picked up by machines, we need to change how we approach marketing from doing marketing to managing marketing. These examples demonstrate that we don’t necessarily need to hand craft an individual piece of writing, but we do need to supervise, edit, and tune the outputs for exactly our purposes.

In terms of your marketing technology and marketing operations strategy, you should be doing two things.
1. Prepare for a future where you are the conductor of the orchestra. Take a hard look at your staffing and the capabilities of the people on your team, and start mapping out professional development roadmaps for them that will incorporate more and better AI tools for easy marketing tasks. Those folks who aren’t willing to invest in themselves and pivot what marketing means are folks that you might need to eventually transition out of your organization.
2. Be actively testing and watching the content creation AI space, especially around transformer-based models. Everything from Google’s BERT, LaMDA, and MUM models to natural language generation to video and image generation is growing at accelerating rates. Don’t get caught by surprise when a sea change occurs in the marketing technology market space – by being an early adopter and tester of all these different tools and technologies, you’ll be ahead of the curve – and ahead of your competitors.
Tools like the GPT family are how we will execute more and more of the day to day tasks in marketing. Prepare yourself for them, master them, and you’ll be a marketer who delivers exponential value to your organization and customers.

Understanding Marketing Supply Chain Risks
When we think about our marketing, we think often in terms of what we do, the activities we undertake. The more analytical among us will think about outcomes and measurements – leads we generate, sales we nudge, etc. But not nearly enough of us think about marketing operations from a truly operational perspective.

Why? For the same reason that we tend not to think in terms of data science or statistics; logistics and operations are separate professions. However, if we turn our gaze to those other professions, there may be ideas we can import to improve our marketing substantially.

The Marketing Supply Chain

Let’s think about marketing operationally for a moment. Forget everything about campaigns or persuasion and think about it as though it were a defined, mechanical process like manufacturing.

If marketing were manufacturing, what would be our output? Probably something like marketing qualified leads or a sales mechanism of some kind, be it ecommerce, a sales team, a brick and mortar store. We produce qualified audiences of buyers.

What are our raw materials we need to make this product? Audiences of relevant people. People who could be buyers, but aren’t yet.

From this perspective, our customer is the sales mechanism.

Our marketing budget, then, is what our buyer pays for our product.

And we spend our budget to buy different audiences. Some audiences are bought with our labor and efforts, like audiences we get from organic search. Other audiences are bought outright from different suppliers like ad networks.

Viewed like this, marketing’s supply chain is easy to see. Our suppliers in turn have to get their supplies from others, and our buyers have to convert our audiences into a product like revenue.

So, what’s the point of this thought exercise? By viewing marketing as a supply chain, as a manufacturing process, we can more easily understand the supply chain risks we face.

Marketing Supply Chain Risks

How much of your supply chain is unstable and at risk?

This year we saw no shortage of supply chain disruptions, from the pandemic to a ship getting stuck in the Suez Canal. Businesses that didn’t have backup plans and contingency plans were hit hardest; some went out of business entirely because they had no inventory to work with; they had pivoted to just-in-time manufacturing, and because their supply chain was so brittle, so inflexible, the slightest disruption broke things.

So, look at your supply chain, particularly upstream. How stable is it? Do your suppliers constantly change their prices? If you do any kind of advertising, the answer to that question is an unqualified yes. If you rely on things like organic search, not only is your supply chain unstable, it’s also unpredictable. Your supplier may send you lots of supplies one day and none the next – and there’s no clear way to negotiate better terms.

Downstream, how stable is your supply chain? Does your buyer change what they’re willing to pay? Again, anyone who’s been through marketing budget cuts – which is an organization effectively saying they’re not willing to pay more for the product – has experienced an unstable downstream supply chain. Even demand may change; the customer – our organization – may want to buy less marketing. When the pandemic struck and demand fell off a cliff for many things (and skyrocketed for others), customers spent less, and our organization may simply have lost its ability to pay for our outputs.

So, our supply chain may have substantial risks and instability in it. What’s the solution? How do we create a more stable marketing supply chain?

Building a Better Marketing Supply Chain

As with any supply chain, the answers are straightforward (but not easy). We need diversity and resilience.

Diversity in our supply chain comes from having multiple suppliers, and more reliable suppliers. Just as a manufacturing organization may have multiple partners from which to source parts, we need multiple suppliers and partners to source audiences from.

Run an attribution analysis on your marketing. If all your audience comes from one or two sources – especially sources not under your control, like Google organic search – then you are at risk from supply chain disruption. Strive to have a more balanced portfolio of suppliers. Work to create more relationships with reliable suppliers, which in marketing would be influencers, partnerships, people and organizations who share your audience but are non-competitive. If you had two or three reliable partners who could supply you with audiences, then you could break the habit of needing to rely on, say, paid ads or organic search.

Resilience in our supply chain comes from having inventory. A shock to the system in regular manufacturing means that you draw down what little inventory you have on hand. This is what has broken so much of modern manufacturing today, why shortages are occurring with greater frequency. Because so many manufacturers have so little inventory on hand, even a small supply chain disruption can break an entire business.

From a marketing perspective, if we are simply buying our audiences from paid ads, and a supply chain disruption happens – say, prices double – then our marketing will break. We won’t be able to meet our obligations. How do we avoid that? By having inventory on hand.

How does a marketer have audience inventory on hand? Unlike physical goods which take up space in a warehouse, marketing inventory only has operational costs: maintaining strong relationships with our audience. Providing them constant value. Creating communities. Having powerful owned media properties like an email list. All these are effectively stored inventories of an audience. By building and keeping strong our relationship with our audience, we build our inventory of our own audience. When our buyers ask for more supply, or when our other suppliers fall short, we have inventory to draw down on.

Here’s a starter exercise: take your single largest supplier of audience, be it Facebook ads or Google organic search. If that supplier dried up tomorrow, what would be your fallback plan? How would you compensate for the loss of that supplier? Build plans to deal with scenarios like this.

Build Your Marketing Supply Chain

Your next steps should be clear. First, chart out your existing supply chain. Who are your buyers? What are they willing to pay (i.e. your marketing budget)? Who are your suppliers, and how much do your supplies cost?

Run the aforementioned attribution analysis and understand how at risk your supply chain is from disruption. Build scenarios for disruptions and have plans on hand for when your supply chain breaks. If the pandemic has taught us nothing else, it illustrates our need to plan ahead and be ready for disruptions.

Once you’ve built an understanding of your supply chain, start mitigating risks. Identify new suppliers; build diversity and resilience into your marketing so that disruptions have less of an impact. If you do this well, you’ll be ready for whatever the world throws at you, and may even seize a competitive advantage from other companies who aren’t as well prepared.

Find New Marketing Strategies with the 2×2 Matrix
Let’s take a moment to consider the simple, humble 2×2 matrix. This business strategy tool is heavily used, from publications and speeches to every case study you’ve ever read in business school. Every major consulting firm has thousands of 2×2 matrices on Powerpoint slides laying around.

Yet the reason why it’s so overused is because it works so remarkably well at solving two problems: binary thinking and one-dimensional thinking.

Overcoming Binary Thinking

The first blind spot the 2×2 matrix helps us overcome is a tendency towards binary thinking:
- What’s the solution to this problem?
- What’s the answer to this question?
- Should I do more of X or more of Y?
- When’s the best time to post on Instagram?
These are all questions that hint at binary thinking, looking for a simple, black and white answer – when the answer may not be binary. The simple 2×2 matrix helps to get us thinking differently by breaking us of the habit of assuming there is just one answer when there may be a spectrum of answers.
- There may not be a best time to post on Instagram, but a series of them.
- The best choice may not be X or Y, but a little bit of X and a little bit more of Y.
Here’s a simple example. Have you ever had a heated debate with a significant other about what to have for dinner? Rather than argue, put your choices in a 2×2 matrix based on proximity and price. Now it’s not a binary question, but a spectrum of possibilities:

Using the 2×2 matrix to discuss a marketing or business challenge – or any challenge – opens our mind to more possibilities, rather than a definitive answer.

## Overcoming One-Dimensional Thinking

The second blind spot a 2×2 matrix helps us to overcome is a tendency towards one-dimensional thinking. Especially in analytics, we tend to focus on a single metric at a time, like website visitors or Twitter followers or Facebook Likes. We focus on ROI or net revenue or daily downloads, and we look at a metric often to the exclusion of other related metrics that can help lend additional context.

The simple 2×2 matrix expands our mind a little bit by exploring how metrics work together. What else might impact that metric? What is the relationship between one metric and the next? If we see a strong relationship, what might that tell us about how we should implement our marketing strategies?

Consider two very simple metrics from our Google Analytics data, new visitors and returning visitors. These measure different behaviors of an audience; new visitors tend to be a result of our marketing efforts, while returning visitors tend to be a result of the quality of our content. Rather than focus on just one metric alone, what if we plotted out these two dimensions?

By laying out these two metrics and the relationships they have to each other on a basic 2×2 matrix, we develop a framework for evaluating important metrics together. I’d next take my blog by page and plot it using the chart above as a reference:

The 2×2 matrix gives me a plan of action:
- I can now categorize my content and repair the content that is in the bottom left quadrant first.
- I can add more promotion to content in the bottom right content.
- I can tune up and refresh content in the top left quadrant.
- Once everything is fixed, I can find new ways to elevate the content in the top right quadrant.
Use the 2×2 Matrix to Overcome Blind Spots

Just because a tool is overused doesn’t mean it’s bad at what it does; its overuse may indicate that it should factor prominently in your own work. Keep the humble 2×2 matrix handy, and the next time you’re stuck looking at a problem from one dimension or in a binary way, bring it out and see if it expands your thinking.

The Most Important Question in Attribution Analysis
One of the most important questions you can ask a prospective customer is one almost no one asks:

How did you hear about us? (or its many variations, like “What made you come in today?”) is a question we don’t ask nearly enough.

Why? Why don’t we ask this critical question, a question that is the linchpin of attribution modeling? After all, nothing cements attribution analysis more than answers to an unaided recall question. If you can’t remember how you heard of a company, then that company’s marketing is clearly not very good.

More important, asking people how they heard about us helps us understand our attribution models much better, because asking people what they remember accounts for interactions that may not be captured in digital marketing analytics.

So why isn’t this best practice universal? Here’s one reason companies don’t do this as often as they should: the data analysis part can take some time if you’re collecting it correctly. Let’s look at an example.

Attribution Walkthrough

I’ve been collecting answers to this question for my newsletter for several years now:

And this is why companies struggle to use this information:

The answers we get from a free-form response are wide and varied – so wide that analyzing them requires a decent amount of effort. Happily, you can use a huge assortment of tools to help categorize the answers; many of them will be semantically similar.

For example, in Excel, you could create a chained COUNTIF statement and tally up words for different categories. I do the same thing programmatically in the R programming language, but you don’t need to use programming software. Here’s an example of how I bucketed the different terms:

An example in Excel of one of these would be something like =COUNTIF(lower(A2), “*spin sucks*”) + COUNTIF(lower(A2), “*gini*”) in a cell in a column. This will help you tag and categorize responses in a series of columns for further analysis.

Once we tabulate the results, we should end up with something that looks like this:

This tells us several things:
1. We’ve still got more work to do on the categories; there are more unknowns than any other single topic for this dataset.
2. Three of the top five sources are sources where there won’t be digital attribution: referrals from a colleague/friend, Ann Handley’s book Everybody Writes, and speaking.
3. Social media plays a fairly large role, larger than I’d expect.
Now, let’s take a look at a digital customer journey for newsletter subscriptions for the same period of time.

We note here that organic search is the top of this particular model. Why is it so much more prominent here than in the version above, using user input?

Logically, if someone recommends something to you, what’s the first thing you’ll do? If someone says, “hey, you should check out Chris Penn’s newsletter”, what will you probably do?

You will probably search for it. This exemplifies why surveying and asking people questions using unaided recall is so important for attribution models.

Take a moment to give this serious thought. If I think organic search is driving all my results – which by the digital model, it is – what action would I take? I’d optimize pages. Build links. Do guest posts. All the SEO tactics that are best practices, known, effective methods for generating inbound organic searches.

But I’d be wrong, wouldn’t I? Because colleagues and friends are referring me, Ann Handley’s book is referring me, speaking on stage is referring me to others. In all those offline formats, their natural output in a digital attribution model is organic search. The reality is, SEO isn’t working for me – referrals are! They’re just showing up as search because the referrals are in offline places.

The same is true for social media. On my digital attribution model, social media drives a handful of conversions. But in the survey data, it’s the fourth-largest source. Why? Why is there such a disparity?

Let’s look at a sample of some of the answers:

Well then. Some of these are Facebook groups, some of these are Twitter chats – and those are types of social media where there might not be a clickstream, a linear journey from click to click that we can follow. In fact, some of these are reputational answers, which maens it’s entirely possible that they too came in from organic search. If you’ve ever had the experience of seeing something on Facebook or LinkedIn and then have had to go search for it, you know exactly what is happening here.

By analyzing the responses people give me on my forms, I now know what’s driving the digital attribution model’s results, and I can calibrate my efforts accordingly. For example, I should be featuring Ann’s book more prominently if I want to drive newsletter subscribers.

Key Takeaway: Ask!

If your data collection on forms and other transactions does not include a freeform way to ask people how they heard about you, or what motivated them to do business with you, then half your attribution model may be missing.

Take time to implement this critical question as many places as practical in your business, and then take the time to analyze the data. You’ll be surprised at what people remember about you – and you can use that data to calibrate your marketing efforts.

And a special thank you goes out to Ann Handley for Everybody Writes. If you don’t already subscribe to Ann’s newsletter, you should.

The Three Whats of Marketing Reporting
Let’s be candid: most marketing reporting sucks. It’s either so superficial and activity-based that it doesn’t tell us anything, or it’s a truck backing up, dumping data all over our desk and expecting us to sort through it all.

Neither helps us improve our marketing. What’s the solution to this conundrum?

One answer is a framework I call the three what’s:
- What happened?
- So what?
- Now what?
Let’s dig into each of these.

What Happened?

What happened is fairly straightforward. What does our data tell us? And yet, even this can be a challenge because an uncomfortable amount of marketing reporting is spent on activities. Take a look at this example from an agency report:

This is what happened, that’s true, in the sense that it is activity based. Someone did those activities. But these are not results. These are not outcomes. At the end of the day, no one cares how hard we worked. Everyone cares what we achieved, what results we brought in.

Look at the results section of the report above. What’s the business impact of these results? What was the marketing impact? Did we earn more traffic to our website? Did we create more conversions? What actually happened? It’s not clear from the results presented what really happened as a result of our activities.

Key takeaway: present results, not activities, in reporting.

So What?

So What? is my friend, partner, and CEO Katie Robbert’s favorite expression. After we present our results, we have to answer the question of so what? So what does this mean? What impact did these results have?

For example, this is the stock Google Data Studio report for YouTube, the template that you’re given as a starting point for using Data Studio:

This is definitely an improvement over the agency report earlier, in that we have quantitative results, but this report completely lacks any context, meaning, or impact. I earned 380 views on my views.

That and $5 will get me a cup of coffee at Starbucks. 380 views doesn’t mean anything. Is that good? Is that bad? Is that an improvement or a decline? This report doesn’t help me understand whether I’m doing well with my efforts on YouTube or poorly.

Granted, there are things that no report can capture. If I changed strategies and started posting cat videos instead of my usual content, you wouldn’t necessarily see that reflected here, and the analysis presented would have to include that, especially if there was a significant variance in the results.

However, in general, even quantitative reports need to explain the implications of the results. Mentally ask yourself after each piece of data, “So what?” to wring more value out of your reports, and keep doing that until you connect the dots to real business value.

For example, let’s say I’m looking at my newsletter issue from this week. I earned 24,637 opens of my email.
- So what? Well, it means that tens of thousands of people read my newsletter.
- So what? That means I sent thousands of clicks to my website and other valuable digital properties.
- So what? That means I generated leads for my sponsors and my company.
- So what? That means I justified the sponsor fees paid.
- So what? That means I can continue to charge the same amount or possibly increase my sponsorship rates.
Ah ha! After playing the So What? game, we arrive at the real meat: I can make more money. Generally speaking, our stakeholders care about earning more revenue, saving time and resources, and reducing costs. Better, faster, cheaper. Keep playing the So What? game until you arrive at a conclusion that aligns with better, faster, or cheaper.

Key takeaway: connect results to business impact.

Now What?

Now What? is the third leg of the reporting stool. Now What? is where we prove our value, by focusing on the actions we need to take, the decisions we need to make. Everything up until this point shows what happened in the past. Now What? is about making decisions for the future.

What decisions do we want people to make? What actions do they need to take?

Here’s an example of the attribution analysis report for my website:

I see what happened – that organic search drove 65% of my conversions for the last 90 days. I see email and social media playing key roles. I understand what happened.

I know why I earned the number of conversions I did, as well as what didn’t earn me conversions.

But the key question is, now what? What should I do more of? What should I do differently? For example, I see that what I share on social media earns more than double the conversions of interactions. I’m sharing the right content, so I need to double down and make sure I’m sharing the absolute best stuff possible. That means digging into more topic research to identify things that garner high interaction rates, as well as building a model of what doesn’t work so I stop sharing content people don’t care about.

I see SEO as a key driver of my website. I need to find out what I’m being found for, make sure it’s aligned with my overall goals, and then double down on the stuff that’s working.

If I were still doing a daily video show, I would most certainly kill it off now. YouTube accounts for 0.1% of my conversions over three months. That’s terrible performance. As a channel, it’s just not working for me – and never really has. In this report, YouTube has proven that even though I got results, they had no impact, and thus the decision I need to make is whether or not to continue my efforts there.

Now What? is where we prove our value as marketers. It’s trivial to copy and paste numbers from a spreadsheet to a slide deck. It’s valuable to explain why we need to either stay the course or change course, and give our stakeholders straightforward decisions to make. If we are the stakeholder, then any reporting we’re looking at should be presenting us with decisions to make and then outline the timeline of when those decisions will be executed.

Key takeaway: any report that doesn’t ask for decisions is not doing the best job possible.

Use the Three Whats Often

If we use the Three Whats to focus our reporting, it will improve. Our reporting will be shorter and much more focused. It will stand out because it creates value and invests time instead of wasting it. And we will make better decisions, decisions informed not only by data, but also analysis and insights. Apply the Three Whats to your marketing reporting today.
