Why have networks become so intent on shaving, then claiming that they don't? I push traffic to an offer and I can consistently get better that 1:10 conversion rate (its very highly targeted traffic). That will work for a day or two, then all of a sudden I look at stats and I'm at 1:50, 1:100 or even worse. At this point I choose the same offer from another "network" and I'm immediately back to better than 1:10. Ideas? Discussion? What have you seen?
