Hi recently I received email from this site called www.Prepopads.com claiming that they are pay per impression ad network popups and banner ads I wonder anyone here heard of them or tried them out ?
not very good...It has 7 levels of countryes ...I get for the 1 (the best) about 0.09-0.14 CPM for popunders.For level one is recomanded to put only one popunder/visitor. Worst for intn
