I really like how Google Analytics displays the results of content experiments. However, it seems the tool only works for simultaneous tests. I'd like to use the tool without implementing the page variation code into my site.
For example, I want to test copy on an ecommerece category page. The original page variation would be the current page for the past 2500 visits. After making the copy changes, the new variation would be for the next 2500 visits.
I realize I can simply record the metrics before and after each variation, but I'd like to take advantage of Google's presentation of the experiment.
Is it possible to use the Content Experiments in this way?
