Anyway, I put each "fandom" in it's own category, and I have put up some general (like: Make Money From Home, Numerology, Dating) banner ads with this plugin I found, and I've been getting a few clicks on those banners.
So I want to split test banners and see which works best for each category.
I do have Prosper202, and also a banner rotator plugin which allows you to set display conditions such as device type, category, OS, country etc.
Should I be tracking the country, OS etc? Or should I just simply see which works best for each category?
