XtendAdvert

XtendAdvert is a site where you earn in Euros! So you earn more, because 1€ ~ 0.77$

You need a website with some post, and not a website empty; a website with fast charge (less than 2~5s).

Their CPM is 0.03~0.02€, and count almost of the impressions, so it's very good.

You have lot's of ads to put, but I recommend you to put "Banners 160x600" and "Banners 728x90".
