Hi BHW, In past, I used cpmfun and their rate was very good like 0,09 ~ 0,1$ ECPM. So, i'm looking to buy traffic from other ad network with similar price or approximately. What ad network do you use to buy cheap traffic? Iframe will be 1x1 and will not open pop or popunder. I'm looking an ad network with 80-90% real human not bot or proxy traffic! Thanks in advance!
