Best payouts refers to returning the largest % of Cost per Action money to the sites that do most of the work. Some of our campaigns are exclusive, the ones that are not we monitor closely to make sure we are giving the highest payout of any of the networks. We also usually provide unique creative so the eCPM is higher as well. Of course, we target the highest eCPM possible, but it's really up to individual site content. Hope this helps.
