How do I track sales through OneBox vs. froogle.google.com?
While this seems initially like it’ll be a simple task, OneBox ends up being very difficult to really track down the sales from. The same feed, which many times has a parameter of ref=base or xsrc=base, ends up feeding Google Base, Froogle, and OneBox results.
What this means is you can’t totally trust your analytics. They’ll easily find those that arrived at a page with that parameter and track the sales, but they don’t typically break things down the way you’re going to want to here.
