In the previous post, we emphasized what the customer journey was not. It’s not just another name for the funnel. It’s understanding how your customers act, not necessarily in a linear fashion, on their way to becoming customers.

Let’s look at a model of a customer journey, using Google’s Customer Journey tool as a starting point. If you’ve never used it before, it’s a handy tool to understand the basic customer journey model.

Let’s say I wanted to see how a website like mine, which is a medium-sized site, should be expected to perform:

According to the generic model for sites like mine, we would expect to see generic paid search and organic search leading the way, followed by referral traffic and display advertising. These would be the front end, the early ways audiences find me. After that, they’d engage with social media, email marketing, and branded search, and respond as customers to direct marketing.

The output of the tool gives a good general concept of your customer journey, but you might have noticed that the tool’s categories lack specificity. Business and Industrial is technically the category my site fits in, but I’m being lumped in with things like industrial concrete manufacturing, and I’m fairly certain my audience differs from a concrete manufacturer’s audience.

How could we get more specific about our customer journey? If you have goals and goal values specified in Google Analytics, the tool provides you with much of the raw data you need to create your own customer journey. Let’s look at where to get this data. Inside Google Analytics, go to Conversions, Multi-Channel Funnels, Top Conversion Paths:

What you see here are the top customer journeys by channel grouping. This is a decent start, and indeed, you could make operational plans just from this information. However, we are never ones to settle, so export this data into the spreadsheet of your choice:

What we see here are our conversion pathways, broken down by conversion. However, what this doesn’t tell us are the individual stages. Using the text editor of your choice, break apart this data using the > as your delimiter and put some header labels up top of the sheet to make it easier to read.

Next, split up each step into separate tabs (for ease of viewing) and subtotal your channels. Repeat this process for the first 3 or 4 steps:

Move all your subtotals to one table and color code it with the Customer Journey colors, and you’ve now got a look at your specific customer journey versus the generic customer journey:

Above, we can see that in my customer journey, direct actually comes first, rather than last. That’s an interesting twist, and one that the generic tool missed completely. The rest – organic search, referral traffic, social, etc. are aligned with the generic tool.

You’ve now constructed your customer journey. Congratulations! In the next post in this series, we’ll look at how to improve it.

The concept of the customer journey is simple: our customers may not follow a linear path to conversion, but they do have a logical flow. If we can understand the customer journey, we can improve it and increase conversion.

What the Customer Journey Isn’t

As marketers, we talk about the customer journey as though it were a generic process that everyone follows; I’ve seen many slides at conferences recently which explain the B2B customer journey or the B2C customer journey.

In reality, most people talking about the customer journey have simply taken their marketing funnel, filed off the word funnel, and replaced it with customer journey. We don’t change our marketing operations at all or make the journey any better by calling it a journey instead of a funnel.

Equally true, your customers’ journey to conversion is a unique, distinct series of processes which are hard-coded to your business, your marketing tools, and your methods. What I’ve said about benchmarks also applies to customer journeys: they are not generic. They are not categorizable by industry. The customer journeys for Smallville Community Bank and Golden Slacks MegaFund are radically different, even though they’re both financial services.

The irony is, customer journeys are easier than ever to understand, analyze, and improve. Tools like Google’s Customer Journey modeler are useful places to start, but they’re by no means the only way to understand your customers.

In this multi-part series, we’re going to examine:

– What the customer journey isn’t (this post)
– How to analyze your customer journey
– How to improve your customer journey

Stay tuned!

How to capture your 15 minutes of fame
“In the future, everyone will be world-famous for 15 minutes.” – Andy Warhol, 1968

These days, your 15 minutes of fame are more likely than ever thanks to social media and the Internet. In just hours, you can go from obscurity to the front page of every news site, from unknown to speaking with national government leaders.

However, as Warhol pointed out, attention is fleeting. No one keeps the spotlight forever. If your company is fortunate enough (or has a good enough PR agency) to get the spotlight, how do you make the most of it?

Here are the basic steps for how to capture your 15 minutes of fame:

Step 1: Prepare. Fame is like a tidal wave. You might or might not see it coming, and unless it’s massive, you don’t get a sense of how powerful it is until the wave breaks. Prepare in advance, the same way a surfer paddles out in advance to catch the wave. What should you prepare?
- An email marketing system. You’ll need a way to capture email addresses.
- Analytics. Best in class tools like Google Analytics let you segment your visitors. Be sure to define goals and goal values!
- Remarketing. Remarketing is a powerful advertising system, but only if it’s deployed in advance.
Example: in Twitter’s Ad Manager, you can set up a custom web-based audience tracker. I’d recommend having a handful of remarketing tags pre-made, with the tracking tags stored in Evernote or dormant in your CMS.

That way, if something starts to happen, all you need to do is fish out the tag and deploy it immediately.

Step 2: Tag. The moment you see the wave headed your way, get your tags live, turn on your systems, create segmentations in Google Analytics, and make sure your audiences are being identified by your systems. It’s important to have real-time analytics turned on so you can validate that things are working as intended:

Step 3: Capture. When you’ve got the spotlight, be proactive (nicely) about asking people to take action. Ask them to subscribe, ask them to follow you, ask them to visit your website/blog. Get them into the places where conversions are trackable, where audiences are taggable. Don’t assume people will automatically do what you want them to do.

Step 4: Remarket. No wave lasts forever. In fact, few waves last for more than a split second. When the attention fades, when the spotlight moves on, reach out to everyone you’ve tagged, tracked, and captured.

As soon as the spotlight moves on, turn on your remarketing ads and remind people why they visited you in the first place. Send them an email with tangible next steps they can take, and what’s next for you. You got the spotlight for a reason; extend that reason with what’s next and why people should continue to remain interested in you.

Whether or not you ever recapture the spotlight, if you prepare and execute well, you can make your 15 minutes of fame deliver lasting impact to your business.

4 ways to tell marketing analytics stories
Data is neutral. It’s amoral. Data doesn’t speak for itself, despite what many marketers say. Data by itself is just a thing. What you do with the data is what gives it value. How you interpret it gives it value. I wrote about this at length in Marketing Blue Belt, but I thought it worth sharing a few basic ideas about how to tell data stories.

We humans are really bad at understanding data. It’s not how our brains work. We are very good at understanding stories, at crafting narratives, at listening to and interpreting each other. In order to tell stories with data, we have to sequence it into a fashion that fits a story. Here are four basic patterns for telling data stories; this is by no means a comprehensive or exhaustive list.

The first story is the ascent up a mountain. Take any broad set of data and progressively narrow it down as part of the story. For example, in the SHIFT State of Social Media quarterly reports, we start by saying Facebook as 1.5 billion users. We narrow that down to 90% of that population that uses Facebook at least partly on a mobile device. Then we narrow further to state that half of that group use only a mobile device to access Facebook. The narrowing tells a story in a way we can follow along.

The second story is the cycle. When we talk about marketing evangelists, this is how we feature the process more prominently than the data. We track audience members to leads to sales to customers to delighted evangelists. The key with the cycle is that it emphasizes the stages our data travels through and that the process never ends, never comes to a halt.

The third story is the journey, the travel from beginning to end. The journey, unlike the process, has a defined beginning and end, a completion. We might explain healthcare data this way, from cradle to grave. We might explain a career in marketing this way, from junior role to retirement. One of the traps to look out for is mistaking when something is a cycle versus a journey – very often, we treat cycles like journeys.

The last story is the one we’re most familiar with as marketers, the funnel. This is similar to the ascent, but (well done) focuses on the losses at each stage. In the ascent, we focus on who’s left, but in the funnel we focus on who we left behind – and how we can get more of them to go from top to bottom.

Fundamentally, all of these story types have a progression that we can mentally follow; by telling stories with focus on different aspects of the progression, we can emphasize or de-emphasize certain parts. Like stage magicians, the story type we choose depends on where we want to direct our audience’s attention.

Have you calibrated your marketing metrics and measurement?
Over the weekend, I noticed that the blueberry bushes in the yard were starting to yellow a bit. Yellowing leaves, after a few minutes of Googling, is apparently a symptom of either dryness or insufficient acidity in the soil. I decided to test for the latter first, since it’s the more challenging thing to test. In order to test for acidity, you need a pH meter. pH meters are devices that determine the number of acid ions in a liquid solution, usually through electrical conductivity, and require calibration.

Here’s where I ran into trouble: I didn’t have a calibration solution on hand. I figured I’d just distill some water and use that to calibrate the meter, because distilled water should have a pH of 7, a known pH.

Unfortunately, it turns out that distilled water is extremely receptive to carbon dioxide in the air and thus becomes acidic very quickly – but not at a reliable rate. What I ended up doing was boiling 1000mL distilled water (to remove dissolved gases), then quickly adding 11.9 grams of anhydrous citric acid to it (to give it a known pH of 4), then sealing it in an airtight container until it returned to roughly room temperature.

In the end, that procedure gives as close to a known pH for testing as you can probably get at home without buying even more laboratory equipment. From there, I was able to test the soil around my blueberry bushes and ascertain that the pH of the soil was far too basic for them to be comfortable, around 8.5 when it should be 5.5-6.0. Why? I re-use grey water from the bathtub, and any water that has soap in it is going to be basic with a fairly high pH. The remedy is simple: just add acid. Adding citric acid or vinegar in a small quantity quickly turns bath water acidic, which makes it perfect for blueberry bushes.

What in the world does any of this have to do with marketing? As you just read, effective measurement begins with calibration, with knowing what the situation is in order to take action. If your calibration is wrong, all your measurement will be wrong.

An obvious incorrect calibration would be something like not having Google Analytics tracking tags on all your web pages. If you’re only tracking some pages but asking for full site data, your instrumentation is giving you wrong information. Calibration in that case – ensuring that you’re measuring correctly – involves validating you set up Google Analytics correctly.

A less obvious calibration error would be incorporating something like an “industry standard” metric in your reporting, such as the “industry standard” email open rate or retweet rate. These industry standard numbers are based off of aggregated, highly generic data sets (sometimes of unknown provenance) and thus you have no idea how they were set. Basing your measurement off them assumes that the provider of the “standard” knew what they were doing.

Even if the “standard” was correct, it would still be less relevant to your specific company; the example I often give in public talks is that your local neighborhood credit union and a Wall Street mega-bank are both in the same industry, financial services. To assume they will have similar marketing performance metrics is ludicrous, but that’s what you do when you use a statistic like “industry standard in financial services”.

Before you embark on marketing analytics and measurement, ensure that you’re calibrated correctly and you know the quality of your measurement tools and methodology. Otherwise, you run the risk of making very bad decisions from incorrect data.

Finally, it was pointed out to me on Facebook that household distilled white vinegar has a known pH of 2.4, and would have been a lot simpler to calibrate from, rather than hacking together what I did. Let this be the final lesson in calibration: the more knowledge you have up front, the easier your calibration will be.

Put down the Oreos: real-time marketing is dead
Put down the Oreos. Real-time marketing is dead.

I mean that metaphorically, of course, and in reference to the famous real-time marketing incident in 2013. If you’re eating actual Oreo cookies, please do carry on.

Why is real-time marketing dead already? For the same reason that the retail investor on Wall Street has no hope of outsmarting high-frequency traders and their automated platforms: humans aren’t fast enough for actual real-time marketing.

During the Republican presidential candidate debate, I had the opportunity to watch the “engine room” at Zignal Labs (client of my employer) real-time monitoring system scan the debate on social media, broadcast media, traditional press, and a few other data sources. It looked a bit like this:

The number of conversations happening at any given split second was somewhere between 750,000 and more than a million. One of their tools displays a word cloud of what’s being talked about; imagine a word cloud that changed every millisecond, hashtags flying by faster than you can see.

In an environment like that, the tradition of “news-jacking” popular hashtags and conversations is almost impossible for a human being to keep up with. Can you jump on a popular tweet or a news story when a literal million more appear every second? Watch how fast opinion changes in this animation:

The @GovChristie / @chrischristie vs @randpaul "discussion" as seen across the United States #GOPDebate pic.twitter.com/bMnARNQCjU

— Zignal Labs (@ZignalLabs) August 7, 2015

By the time you make a statement about who is ‘winning’, the data has already changed under your feet a million times.

In digital marketing analytics, something usually is considered trending when it shows a growth curve, a certain mathematical change. When you look at the actual data stream flowing by with a tool like Zignal Labs that can truly display what real-time looks like, growth curves for content are measured in milliseconds. Individual pieces of content start out, grow, trend, and fizzle in the blink of an eye.

The reality is that for anything significant that’s a broad conversational topic, real-time marketing is beyond the capabilities of humans to keep up with. At best, we can look at summaries of what’s happening to pick and choose what we want to give additional focus to; the very best monitoring tools like Zignal Labs will elevate those items that need our attention most.

Beyond that, we need to leave it to the machines and stick to our strategies as best we can.

Disclosure: Zignal Labs is a client of my employer. However, I was not asked to write about their product, and I was not compensated to do so, beyond general benefit to my employer. Zignal Labs did give me a slice of pizza while I was on-site.

How to measure success without goals in Google Analytics
One of the first maxims of great marketing analytics is to have a goal with an objective value set. Tools like Google Analytics make this elementary to configure; simply decide on a goal and decide on the value of the goal, input it into the software, and you’re up and running.

But what if you don’t have any goals? For example, say you’re the new CMO/VP Marketing and you walk into the company. On day one, you look at their Google Analytics and it’s a mess. Nothing is set up right. How do you begin to estimate what’s successful and what’s not?

Google Analytics has a number of tools ready to go and operational out of the box. One of those is the ability to segment your website’s traffic into new or returning users. Could either of those segments correlate well to goals such as lead generation and purchases?

To find out, I looked at some anonymized data from various types of companies to see what the correlation was. A reminder, of course, that correlation is not causation, but in the case of a website, it’s logically quite difficult for someone to convert without visiting your website, so there is some order of operations.

Let’s look at a few examples to see if there’s some logical connection between conversion and new users, or conversion and returning users. We’ll start with a B2C services company. What’s the relationship between new users and conversion?

Strong, as seen above by a Spearman correlation of .747. If you’re unfamiliar with Spearman correlation, it’s a scale between -1 and +1. A +1 means a perfect correlation; as variable 1 changes, variable 2 changes in exactly the same proportion. Above, we see new users and conversions in a strong relationship.

What about returning users and their relationship to conversions?

That’s an incredibly strong .958. Returning users and conversions are very tightly bound together.

Let’s look at something a little more mundane, a B2C consumer packaged goods (CPG) company, someone who sells brick and mortar goods. New users and conversions look like this:

The correlation is still a moderately strong .612 for new users and conversions. What about returning users?

We’re at .738 there, a strong relationship. Returning users correlate more strongly to conversions than new users for the B2C CPG company.

Let’s flip over to our colleagues on the B2B side. What about a B2B technology company, the kind of company that has long sales cycles and expensive products that only other companies buy?

The relationship of new users to conversions is .913. Very strong. What about returning users?

That’s as close to perfect as you’re going to see in the real world, a super strong relationship between returning users and conversions.

What can we conclude from these three cases above? While new users to your website are important for growth, returning users show incredibly strong relationships to conversion.

Thus, if you’re walking into a Google Analytics installation that has no goals set up, but you still need to judge how things have gone so far, I’d say you can safely use returning users as a general proxy for success while you get goals and goal values set up correctly. Inside Google Analytics, you can examine, using segmentation, which channels drive returning users most and best. You can see what pages attract returning users the most, and ultimately use that as a foundation for determining intermediate goals.

How volatile is your marketing?
How volatile is your marketing?

Volatility is a concept made popular by the stock market. When a stock is more volatile, it means something is happening that is causing investors to buy or sell it in greater volumes. A nonvolatile stock has similar buy/sell volume and relative price stability every day.

When the market as a whole is volatile, it means instability. Something has happened that is making a lot of people act, whether it’s panic buying or panic selling. Investors don’t like instability. Instability means unpredictability, and that can mean significant, unplanned risk.

Back during the financial crisis, VIX, the market volatility measure, was at crazy numbers as people bailed out of stocks. The VIX spiked and trillions of dollars (admittedly all theoretical) vanished in a just a few days:

Why are we talking about the VIX and volatility? You can use the same concept of measuring volatility, but in your marketing metrics and analytics. Volatility in marketing means that something’s happening. It might be good or bad, but whatever it is, it’s worth paying attention to. Let’s take a look at an example, using some of my personal Twitter data. I’ve taken a column of my Tweets and retweets. To measure volatility, we measure how much something has changed from one measurement to the next:

Low volatility means low change. High volatility means big change.

From here, we chart the retweets:

And then finally add our volatility column:

Take a look carefully above at the orange line. In the middle of the chart it gets especially spiky, repeatedly. That was a period of increased volatility. The question to ask is why? What happened during that time period that made my tweets different, more volatile, less predictable in terms of retweets?

The answer, of course, was my speaking at Social Media Marketing World, which was a terrific experience. Michael Stelzner did a phenomenal job of not only marketing the show, but marketing the speakers at the show – which included retweeting our tweets to his highly influential audience. Based on the information above, if retweets were an important KPI for a corporate social media marketing program, I’d figure out ways to increase my participation and engagement in that event. (I will anyway, because it’s a terrific event)

When you’re measuring volatility, determine first if you’re getting volatility that is positive or negative against your marketing KPIs.

Once you know whether it’s positive (such as the example above) or negative, determine whether or not you have the ability to control or influence the cause of the volatility.
- If it’s positive and you have the ability to control it, do more of it.
- If it’s positive and you don’t have the ability to control it, figure out ways to influence around it, such as using paid media or earned media.
- If it’s negative and you have the ability to control it, stop doing it immediately.
- If it’s negative and you don’t have the ability to control it, do something else you’re good at to mitigate it.
Try measuring the volatility of your key marketing metrics!

How to Improve Content Marketing with IQR: New York Times Case Study
How do you know whether your content game is getting better or worse? It’s easy to rely on stock analytics tools, and for the beginning content marketer, tools such as Google Analytics are more than enough. For the veteran marketer who is creating content, how can we know with greater precision whether our content is getting better or worse? How can we more quickly diagnose the bad, double down on the good, and make our program sing?

In part 5 in this series, we’ll apply our lessons in total to the venerable Gray Lady, the New York Times, and how often her content is retweeted. If you didn’t do any of the coursework in part 1, part 2, part 3, or part 4, go back and do those examples first.

We’ll begin by examining the New York Times’ overall record. In the last year or so, they’ve tweeted an astonishing 39,000 times, more than 100 times a day. Overall, their tweets are retweeted an average of 144 times. Let’s begin by setting up our lower quartile and upper quartiles. We’ll measure over a 7 day rolling window, or 700 rows at a time:

Next, let’s plot our bands. What do you see?

Attach the trendlines:

And refer back to our handy chart:

What we see is that the New York Times has a solid and growing content marketing program, a successful one where the best stuff and the worst stuff are both growing, but the best stuff is outpacing the worst stuff.

Let’s add in the interquartile range measurement:

We now have a very clear picture in just a few minutes of how the New York Times is faring in its content marketing program, at least from the perspective of retweets.

What’s the next step for the New York Times? To sort its content by whether the number of retweets is above the third quartile boundary or below the first quartile boundary, then examine what the best content has in common.

Try the IQR methodology to determine how well your content marketing is going!

How to Improve Content Marketing with IQR: Part 4
How do you know whether your content game is getting better or worse? It’s easy to rely on stock analytics tools, and for the beginning content marketer, tools such as Google Analytics are more than enough. For the veteran marketer who is creating content, how can we know with greater precision whether our content is getting better or worse? How can we more quickly diagnose the bad, double down on the good, and make our program sing?

In part 4 in this series, we look at the mathematical gulf separating our best content from our worst, and what that gulf means. If you haven’t read and done the exercises in part 1, part 2, and part 3, go back and do those first.

The difference between the best and worst performing content is the difference between the boundaries of the upper and lower quartiles. This is called the interquartile range, the IQR. The IQR (which we’re finally getting to in part 4 of the series) is a way to mathematically express how far apart our best and worst are. If the IQR were very tiny, it would mean very little variation between our best and worst content. If the IQR were gigantic, it would mean extreme variation between our hits and misses.

Let’s look at the IQR in our sample spreadsheet. What do we see?

We see that except for a significant anomaly in the middle of the chart, the IQR otherwise appears relatively constant. Let’s add a trendline:

We see the trendline remaining flat as well. A flat trendline indicates our content popularity isn’t increasing or decreasing.

What does this tell us? The IQR helps us to understand our relative content popularity. An increasing spread means the popularity of our good and bad content has diverged. Something’s changed which has changed how people perceive our content. A decreasing spread means our content is becoming more homogenous. The difference between a great post and a bad post, in terms of popularity, is shrinking.

The IQR lacks context, however. For that, we’ll need to refer to the previous chart:

The spread/IQR tells us how fast things are diverging (in examples 1, 4, and 7) or converging (in examples 3, 6, and 9).

If both your great stuff quartile and your bad stuff quartile are ascending (see the previous post and examples 1, 2, and 3 above), then a converging IQR may not necessarily be a bad thing. The rising tide of popularity will lift all content.

If your great stuff and bad stuff quartiles are both descending (examples 7, 8, and 9 above), a converging IQR is really bad. Everything is losing ground, and you need to pivot immediately.

This concludes our in-depth look at interquartile ranges and how to use them to measure your content marketing. Try these techniques out. You don’t need to do them more than once a month, but you should test to determine how well your content is doing, using any relevant content marketing metric.
