I've been running it on several sites, including my blog, and the earnings have been terrible. I'm yet to hear of any non-US sites making any real money, apart from A list bloggers, who probably get a high percentage of US traffic
You are correct, Chitika works best on US sites where the competition for CPC is the highest. Locations where there isn't as much competition for local stores who advertise there the CPC will be much lower. Chitika also works best on product based sites... Sites where the main topic is physical products. General "info" sites, personal blogs, etc generally have poor performance from Chitika.
That isn't correct. Chitika accepts traffic from: Australia, Belgium, Canada, Denmark, Germany, France, Italy, Netherlands, New Zealand, Norway, Spain, Sweden, UK, US. I think Canada too but didn't see it on the list and there could be a more recent list available.
chitika ads look the coolest. I wish they accepted me in their program. But listening to you guys here, I guss its ohk I wasnt accepted.
In fact is not traffic, but your content. Chitika only accepts sites with technology, information and other relevant content.
