This is the 1st time that I have ever had to leave a bad review/report. I have been a publisher with Adprime Media for several years now after they approached me, and although I get a pretty decent CPM of about $4, they have never paid on time. I've had to remove the ad tags on countless occasions to get them to pay. So now I have August, September, October and November earnings outstanding. Be careful of this company, not all is well there.
UPDATE In all fairness Adprime Media has been good enough to bring all payments up to date, so my final verdict is if you are willing to wait/haggle for payment then you will eventually get paid.
In my opinion, there is no need be worried as long as the Ad networks pay to publisher, though sometimes not on time. Yes, That's not good but still paying.
Health niche. Yes, I agree, and that is why I have stuck with them for so long. It's more of an annoyance, especially when it happens all the time.
