Here’s an update to Erik Vasilik’s “Poor Man’s GWO/Analytics Integration” technique. The latest iteration of the technique used GA’s user-defined variable to store the combination the visitor saw. Here’s an update to that technique, but leveraging the new Custom Variables just released by Google.
To integrate with an MV test, you need to replace the code
with
You will need to make a few modifications to the code.
You will need to be very careful as to where you place this script. The function _setCustomVar must be called before the call to _trackPageview. This is because custom vars are sent with the next call to either _trackPageview or _trackEvent. This is in contrast to _setVar, which sends it’s own request when the code is executed.
Here is some sample code for how the order of execution should appear:
As with the old GA/GWO integration technique, special consideration must be taken for A/B experiments. Because the page redirects to the “B” page before any analytics code is run, we need to insert the custom variable code between the code that defines the “utmx” function, and the code that actually runs the “utmx” function. Using UDVs, this was easily achieved by inserting the call to _setVar between the two pieces of code. But, remember how I mentioned that MCVs are sent along with the next call to _trackPageview or _trackEvent? Well, setting the custom variable, and then sending either a pageview or event will have a really negative effect on your bounce rates. Especially if your A/B experiment is on a landing page!
To track the A/B test correctly, you can implement one of the following solutions:
