I've been expecting someone to run with a version of what Chitika has been trying. This looks close. Contextual plus targetting past behavior. I'm only comparing to chitika's dynamic ad banners. The big question remains...how effective will Omakase's ad selection algorithm be? I have to think if it isn't that great yet, it will get better. It seems a lot of webmasters are reacting to what ads are displayed to themselves. I wonder if there is anyway of tracking what is shown to visitors?
