Which is better? Google Analytics’ $ Index or CII?

Today I posted my first entry as guest blogger on Jason Falls’ Social Media Explorer. Not surprisingly for those who know me, I kicked things off with a description of Content Index Index — a general description and a case for its use. Posting something in such esteemed company is truly humbling and frankly more thrilling than is probably healthy to admit. (I can hear friends and loved ones chiming in now about all of my work / life balance hoo-hah!)

Content Interest Index — CII for short — forgets for a moment whether a particular user has “converted” in that user session. It scores a page’s content on behavior that takes place on that page only (or offline, regarding that page’s content, in social media). That’s quite different from the scoring of, say, a page in a conversion funnel. Google Analytics (GA) has a Funnel Report that gives value to the pages leading directly to a conversion (Google calls these conversions “Goals”).

Another GA metric that tries to rank based on conversion is its “$ Index.” This can be compared to Google’s PageRank,  but it’s for estimating dollars earned by a page view, not search engine Google juice conferred by the quality of back links a page receives. It confers a portion of the dollar value of a conversion (Goal) onto pages that were viewed in the same session. Here’s an explanation and some examples (the graphic below is from that post):

Those GA scoring systems are all about the conversion, which I’m usually all for.

But as I mentioned in my post on Jason’s blog site, and yesterday, at a Translator Lab Hours discussion, people “snack” on content. They may come back to your site many times before they convert.

That means the session where they convert is likely to be brief, and the pages viewed (the ones given $ Index value) can be unfairly inflated in value.

Follow me here, and on Jason Falls’ Social Media Explorer, to learn more about how CII is calculated and how it can be used to improve the content on your web site that surrounds your conversion funnels.

Overcoming the treachery of analytics

What do these three quotes have in common?

  • “Worship no false idols” — The First Commandment in the Old Testament
  • “If you meet the Buddha on the road, kill him” — Zen adage
  • “Become a ruthless killing machine when it comes to metrics/data” — Avinash Kaushik in a recent blog post.

If you guessed that they all warn (with increasing violence!) against mistaking the symbol of something for the real thing, congratulations! You won a pipe. Surrealist painter René Magritte painted this particular pipe as a way to get us thinking about the paradox of symbols. Under it he painted a caption, “This is not a pipe.”

To drive his point home, Magritte named the painting, The Treachery of Images.

So how can we know when it’s time to wage war against our own treacherous web analytics? And once the body count has been tallied, what takes their place? What do we use to answer key questions and spur appropriate actions?

Results Simply Summarized

The answer: Show your audience only what they really want to know — not mere numbers and measurements, but the other RSS: results simply summarized. Here’s Avinash’s post for the full story.

And here it is in a nutshell:

He describes a favorite application he downloaded for his Nexus One phone. It’s a cardio trainer. The app starts out just like another popular body monitoring system. I’m thinking of the Nike Plus application for the iPhone. Both give the standard run-down of miles run and progress achieved, compared with past sessions.

The cardio trainer app then makes an elegant attempt at RSS. Avinash, for one, feels that it succeeds. I agree. It refocuses attention past the numbers to the actual workout goal.

At the end of each run, to reflect his level of exertion, Avinash is presented with an award of sorts. The screen shows two pieces of fruit — two pairs. They represent the number of calories burned. The pairs are his to enjoy guilt-free. (Or he can imagine a calorie-laden equivalent, in a mental swap of one food for another. Perhaps the next version of the app will allow users to actually do this; To replace the outline of two pears with a rendering of a candy bar, or a couple of bottles of beer!)

You might think these graphics are the same as Magritte’s pipe — mere symbols; not the real thing. You’d be overlooking a major distinction.

All Magritte was doing was showing the pipe. Avinash’s workout app was presenting the pears — awarding them. It was the summarization of the data behind it, proving to Avinash that this was his hard-won snack. It says, “Here you go. You earned it.”

Connecting On Two Levels

The representation of the pears became something he could connect with — both rationally and emotionally. Unlike Magritte’s pipe, the pears are results, supported by evidence. Consequently, for the recipient, they become so real that person could almost taste them!

Sadly, if most analytics pros were asked to cut out their own distracting and unpersuasive metrics, little would be left. Most metrics talk and talk but never get to the point.

This is precisely what senior management does not want. They want quick and truthful take-aways. Will they be dining on one delicious pear this month, or two? Or will there be none at all?

Of course business leaders wouldn’t want to see pears in their analytics. That would be absurd. So what do they care about? They want to see money of course. Or at least, clear proxies for money. Showing images of people is always good, since selling things to people is the surest path to making money. With that in mind, consider using generic silhouettes of them, shown judiciously, and with data that supports their numbers on the page.

Be bold. Show senior management that their site generated more sales leads this month — as represented by silhouettes of cookie-cutter executives (presumably eager to know more about the product). Count them. How many more are there this month compared to last? Line them up for comparison, month-to-month or year-to-date.

Or, as another example, show how the website is lowering operational costs. Illustrate the success of answering more consumer questions online versus having these people call your pricey phone center. In this case, the graphic could be a string of telephone headset icons. Compared to last month, are there fewer of them shown, or more?

Go on your own metrics killing spree, but first, know what you’re pursuing.

Kill any metric that produces more smoke than light. Allow the remaining metrics to build upon each other and add richness to your story. Then, as a satisfying grace note, find that single graphic which best sums up the current situation. Use symbolic language that is meaningful to your audience, to transcend facts and figures.

Do this, and far from being Magritte’s pipe, this graphic will be your own “Avinash’s pears.”

Counting unique site visitors shouldn’t be so hard

If you and I pulled up a site’s analytics, and I asked you to show me the key performance indicators (KPIs), the chances are good you’d start with Unique Visitors. Google provides that figure near the top of its Google Analytics (GA) dashboard.

Behind that number is a story that can make the best of us wince — or in the case of the esteemed Avinash Kaushik, laugh nervously.

The story behind it is like a cross between a Senate Budget Reconciliation Hearing and an episode of The Sopranos. It includes numbers that never add up, shifting definitions of a word (“unique”), and one powerful yet tragically flawed KPI that is quietly driven out to the woods and eliminated. Although the people at GA don’t call it that. They call it being “deprecated.”

I was reminded of this when a client emailed me asking for clarity. There had been a discussion of Google Analytic’s “Absolute Unique Visitors” and its “Unique Visitors.” She wrote: “So let me see if I have it right regarding the difference between an absolute and regular unique.  An absolute is someone who’s only visited once during said timeframe and is counted as one. Unique is someone who’s visited any number of times during said timeframe and is counted as one? Is this correct?”

My reply was longer than I would have liked, but had some things about it that could be helpful for others of my readers. A version of it is below, with all client information changed or eliminated. It began with this: “Your definition of the absolute unique visitor is exactly correct. Your definition of the (merely) unique visitor is also exactly as I’d described it — although in your description you used a “metric” (which is a type of visitor) to define a “dimension” (which is a number, as in a visit count).”

Here are two reports combined in one graphic, both from snapshots of a site's analytics. I chose it because of the numbers. They're small enough to add up; which is still often a tall order in web analytics. Also, because of their size, they

Metric versus Dimension, you say?

Understanding what a unique visitor is requires knowing a bit about how the system measures things.

Google Analytics allows for flexible reporting by creating categories of things, Dimensions, and then counting them using Metrics.

Think of how you describe a newborn’s vitals stats:

  • Weight = 6 pounds 5 ounces
  • Length = 18 inches

(By guessing at that last number I may have inadvertently revealed that I’ve never had a child or been around a delivery, and haven’t a clue what a typical newborn’s length is).

The point is the first part of the sentence is the dimension and the second part, which is the counting part, is the metric. Thrown in at the end is the unit of measure — ounces and inches.

Google Analytics blows people’s minds by having both a dimension and a metric to describe one thing: visitor frequency.

This is sloppy, and it’s a measure of how Google improves its products in gradual increments. GA is an analytics system that is excellent but experiencing growing pains.

It is here — with GA’s parallel accounting of visitors — that the whole unique visitor thing starts breaking down.

You see, in the GA API data dictionary, there is a dimension called “ga:visitCount.”

In October of last year Google started phasing out its predecessor, “ga:countOfVisits,” from which the “Absolute Unique Visitors” had always been generated.

Now when you look that old dimension, the data dictionary describes it this way: “… (deprecated) … See ga:visitCount.” If you look for ga:countOfVisits in the GA API data dictionary, you’ll even see it’s been grayed out.

The description goes on to say this now-mostly-vanquished dimension is the “Number of visits to your website,” and is, “calculated by determining the number of visitor sessions.”

So it’s “ga:countOfVisits = 1” that gave us Absolute Unique Visitor.

For my clients, when I look for that old workhorse of a KPI in the GA Dashboard navigation, I see it’s gone totally missing. Does yours still have it? The answer depends, I’ve been led to believe, on where you are in the phase-out yet. Eventually the Absolute Unique Visitor will be completely wiped out, in favor of “ga:visitCount = 1” — Unique Visitor.

There is also a metric (as opposed to those two dimensions I was telling you about), called “ga:newVisits.” This is extremely useful. But it is a metric, so it can only be expressed when paired with a dimension (is 18 inches meaningful at all if it wasn’t associated with a newborn?).

The data dictionary describes this metric as “The number of visitors whose visit to your website was marked as a first-time visit.”

The Man With Two Watches

This is a lot of ways to find the same thing — How many visitors, without repeating any, have come to your site? I’m reminded of the Chinese adage, “The man with one watch always knows what time it is. The man with two is never sure.”

The only reassuring news is this:

It is only analytics reporting that goes much deeper than a superficial number that actually provides actionable insights. Visitors — unique or otherwise — only become truly important to a business in terms of what they have done and what they’re doing now!

If you want to share a laugh about this topic, I present this YouTube video of Avinash fielding questions from viewers. He laughs nervously, but then provides the news that the phase-out is gradually progressing:
