I have been promoting Singlesnet.com on facebook using targeted PPC and CPM and in the last 3 hours I have received 106 clicks, but not a single conversion. Does the network have to approve the conversions, or what? They payout 4.5 per lead, and like I said, I have targeted traffic, so there's no way not a single person has converted.
106 clicks is not enough to judge. If you would not get a single on 500 clicks, that would be something to worry about
