i have not used that site, but i can say i used adbrite i got lots of traffic and very low conversions. were talking thousands of clicks and nothing. so i dont recommend it at all.
So true, Adengage is the same, my counter went through the roof, but no conversions, so what kind of traffic is this and what good can it do…will it improve your alexa rank, your google pr, it must have some positive attribute, i’d hate to think i just threw my money away
