Hello, I read the article of Idreamer Adsense Increaser eBook.pdf. The problem that in my site get exposure all over the world. And I do not know which ads are for people from abroad so I can block them. What can I do to increase the CPC? thanks
Forget the ads, focus on your traffic and content. Google adsense has an inbuilt system that sends you a higher paying ad depending on the origin of the traffic and the returns the advertisers get from the clicks generated on your blog. So, just focus on the content and your CPC will improve. Also, try having fewer ad units so that the low paying ads do not enter your site.
Your content and site focus determines what ads are shown on your site, a higher paying niche or even internal topic discussion will reflect in adsense.
