Of course, in your opinion. Currently I'm using the $50 ad credit from Bing and it's doing pretty well, I guess. I'm in the entertainment/video niche, so I have pretty low RPM. Previously, I've used Facebook, MyLikes (used to be better, but does give really shady traffic once in a while) and Stumbleupon (horrible conversions and high bounce rates). I have a phone call scheduled with Taboola, since they are apparently good with video entertainment websites and such. Not sure if they will allow me to test drive with a few hundred bucks before throwing the big bucks into the ad campaigns. Anyone else want to share what their favorite/best and AdSense safe ad network is? I'm specifically interested in PPC. Thanks for any help.
