I saw a very strange thing with Chitika recently.
I integrated Chitika box into the page and saw... Google AdSense box instead of Chitika! Wow!! What a surprise!!
I opened html code of the page and it shows chitika code, not even a track of adsense. Still, I see adsense.
Maybe chitika is just using adsense to monetize on keywords that they don't have in there database (I mean don't have products/services in their). Has anyone faced it?
