Currently I use Adsense and ValueClick to monetize my website. Adsense is doing great job on this but VC is showing non-paid campaigns very often.
I am looking for good end of chain campaigns for the VC so if the VC’s CPM is, lets say, below $0.2 it will be redirected to default campaigns from other ad networks.
Any suggestions for end of chain ad networks would be highly appreciated (specially outside US/UK/Canada). Thanks.
