There is a function in your adsense under: Adsense setup > Ad Review Center Does anyone use this and have they had more success with earning from blocking some of the networks? These are the networks you can block: Google Testing Network Bizo Adchemy Aggregate Knowledge Brand.net Collective Media I'm not sure if you blocked some of the networks your earnings could rise? Any ideas?
Not too sure about these networks to be honest but recently i found a lot of USA advertisers on my UK website. Guess what, clicks are decreasing because of this and i had to block these advertisers.
