I've been trying to get an A/B test setup using Google Analytics Experiments. I want to track ctr on buttons on my site so I can test various colors. Right now the numbers I'm getting seem much too high, which are 89-91% CTR with about 100 users each to one of three page variations. I'm not clear on how to setup the experiments correctly, and their documentation makes it sound like you just enter whatever you want "clicks" "downloads" "plays" etc. When I entered it to track clicks with my button title it gave me an estimate of 2-3% ctr based on previous traffic.. this was too low and actually tracking this way has given 0% ctr across the same 300 visits. The 90% ctr is when I'm attempting to track clicks to amazon.com which would also include pictures.. If anyone has experience setting up split testing with Google Analytics I'd love some help, or if you know of a free alternative please post it.
