I had a webmaster that was using exoclick on his tube and after he switched to a system where he sends all non-us traffic to
SGM. And sell all US traffic to
Plugrush with
JuicyAds with a backup buyer, he was making WAY more. Especially since SGM rebills a lot so after a few weeks the money is much better than with exoclick.
