I have a technical blog (programming related) which has around 500 visit per days, 70% are international visitors and 30% are from US/CA.
Google Adsense disabled my account due to invalid clicks so I can't use them (no need to explain here, they suck hard and never respect and listen to the publishers' appeal)
I have tried adbrite and recently using chitika but they almost give me nothing, e.g.
13,865 Page Views 4 clicks $0.01
The performance is so poor even I don't want to mention about it. I am already putting a full top banner and a 350x200 box in article body.
I am researching if any alternative would provide more revenue for my internation visitors or technical visitors.
