I'm trying to merge my Google Website Optimizer A/B testing with Google Analytics (in order to see how page variations affect stats like bounce rate, time on site, etc.). Eric Vasilik, who I believe works at GWO, recommends a technique for doing this that involves setting a user-defined GA variable that is dependent on what page variation the user has been shown. The description of his technique is here: http://www.gwotricks.com/2009/02/poor-mans-gwoanalytics-integration.html
Erik suggests calling the utmx() function on the "original" and "variation" pages in order to grab which page the user has been shown. But when I try doing this, it only works on the "original" page. This is because utmx() is undefined if the GWO control script has not been called, and that script only goes on the "original" page.
Am I missing something here? Since Erik works for GWO I'm sure he's right and I'm misunderstanding the technique, but I can't figure out what I'm doing wrong.
