Errors of causation in web analytics
The other day I was presenting the findings of some analysis to a client. The focus of this analysis was to discover the behavioural factors affecting checkout completion rates in order to shed some light on why people drop out. For example, within this analysis I was able to say fairly basic things such as:
- Visitors who spend a lot of time on the site before their purchase are less likely to drop out of the checkout process than those who’s session is shorter
- Visitors who land on the homepage are more likely to drop out of the process than those who land on a product page
Now, the client immediately got rather excited about this and began to say, regarding the first point, “Wow, so if we can increase the time on site then we can improve our drop-out rates. Excellent, how do we increase time on site?”. Had I allowed it, this person would no doubt have been rushing back to the marketing team with a new objective to get the time on site up!
So what’s wrong with this? Well, apart from the very numerous issues with dwell-time associated with this specific example, this represents a very common misunderstanding in web analysis. Put very simply:
Your customer didn’t complete their purchase because they were on your site for a long time. They were probably on your site for a long time because they are interested in your products and your site is relevant to them which, in turn, means they are more likely to complete their purchase. Increasing dwell-time per se doesn’t make any sense in this example because it isn’t the cause.
To provide a simpler example of this: you might notice that people who dress smartly often have quite tidy hair as well. Does this mean that dressing smartly causes tidy hair? If I put a suit on, will my hair instantly become much tidier because I’m wearing a suit? No, there is some other factor (the person’s need to look smart) that is driving both of these things.
This leads to all kinds of problems in web analysis, some of which are quite subtle. Furthermore, this problem is inextricably bound up with our obsession with click-stream; if we can’t see beyond the web analysis tool then we have to find our causes within it. The biggest danger is that we stop being able to see our visitors as real people with real needs, and instead just view them as lines of data or collections of behaviours.
A couple more examples of how this can cause problems:
- You notice that direct traffic is of a higher quality than other sources. Does this mean that you should simply get more people to come to you direct? You could do this by displaying your URL as a static image in non-clickable banners, meaning that people have to physically type it into the browser. Again, no. Real direct traffic is direct because of brand familiarity and relevance, which may have nothing to do with advertising. The pure fact that it’s direct is of little relevance. (by the way, be careful – direct traffic isn’t always what it seems)
- You notice a correlation between downloads of your latest white paper and calls to your salesteam. Excellent, the white paper is a succesful acquisition tool and is driving leads! Or is it? Which way round is it really? Are people calling you because they downloaded the white paper, or did they look at your site and dowload the white paper because they called you?
Remember, correlation does not imply causation! You can avoid this by remembering that your customers are real people with needs, desires, habits and lifestyles. They are not lines of data with dwell-times, page counts and completion rates. These things are only behavioural indications of something else more complex that is happening. Look beyond the click-stream and understand how your customers think and feel.
Analytics Direct Traffic is NOT What You Think It Is
Analytics direct traffic reports are often viewed as both a highly insightful metric and, in itself, as a particularly valuable stream of visitors. These are people that typed your URL directly into their browser, right? They must have seen your TV ad or just been really engaged with your brand because they remembered your address and didn’t need to use search. Who could ask for better visitors? They are motivated and focused and really intended to come here.
This kind of language continues to dominate all kinds of discussions about web analytics, including blogs, forums, and articles – and even reaches into the field of the experts; just look at the way Google Analytics defines direct traffic. It’s even more worrying when I hear the way my clients talk about it!
The fact is, this definition of direct traffic in web analysis is extremely misleading. It’s true that the direct traffic bucket does include bookmark traffic and typed URLs, but these days (unless you are very strict about your campaign tracking parameters) it can and does include all kinds of other stuff. All it really means is that the session started without a referrer being passed by the user’s browser, and this can happen for lots of reasons as defined in this rather neat list. I have done some tests on some of my clients’ sites and estimate that in some cases up to 90% of ‘direct’ traffic is infact banner ad or PPC traffic!
Here’s an exercise you can perform that will demonstrate exactly how prolific this problem is: as you’re browsing the Internet and following links from one site to the next, you can check the referrer that is passed by typing the following snippet of code into the address bar of your browser:
javascript:alert(document.referrer)
For example, if you visit a site like AOL and click on one of the advertising banners, when you arrive at the destination page replace the URL with the code – a pop-up will appear showing you the referrer (or nothing if one wasn’t passed). Try this with different types of sites, banners and links. Also try it with different browsers. As you will see, quite a lot of the time the referrer is blank. This means that your visit would have been counted as direct traffic in the analytics reports of that site!
So, it’s time stop thinking of direct traffic as people typing in your URL, this isn’t necessarily the case. ‘Other’ or ‘unknown’ would be a more accurate description.
It’s also time to realise the importance of campaign tracking on your inbound links, as Avinash Kaushik points out in his definition of analytics direct traffic. If you always ensure that your links are passing source and campaign info, then you are forcing the referrer field to be populated even if the browser doesn’t pass it. Here’s an easy way to build campaign tracking URLs in Google Analytics.
