If you sell your traffic through a traffic broker you make it so that a middle man will get a share of the potential profit from that ad spot, also the buyer of the ad spot could get a lot of the potential earnings from that ad spot. If you instead promote dating services directly through their
affiliate programs, and make an ad that engages, you can reach a much higher level of reward. If you haven't yet I would try out
Adult Friend Finder which has GEO ADS, a big brand, high payments for referred customers. BTW your niche is gold as dating has the best payed adult affiliate programs out there
