Have anyone ever tried popads? I read some articles and read some reviews, and it seems like popads is a popular ad network for popup out there right now. I just joined recently but don't know how to make the most money out of it. How much should I set my minimum rate? Should I allow additional popup? And should I set a minimum number of popup per session? I also would like to know if there is any good ad network out there for popup or popunder? Thank you.
