nice idea. I tried to setup a new a/b test for a site and it became 'not easy' when I wanted to track an adsense click as a goal.

I wrote a manual a/b test for the same site about 7 years ago, and got adsense click goals working with 40 variations of the page, after about a week of working on it after work at night after my regular job.

There is some jquery code you can add to track javascript events which would probably track adsense clicks, but it's 'not easy', ie: I might as well not pay for it.

Cool idea though! I would pay for it if I could track adsense clicks without having to write code. Also, having an option to select multiple dom elements at once would be nice. In addition, logging into the web site and editing the html to add the code in the <head> tag would be nice too, especially since it's kind of a hassle for me to open eclipse and re-deploy to app engine at 1am when I am tired.

haha, hope this helps.
