Hello! I have recently found a new CPM network. Now, I finally get some nice revenue from my sites. It is called TrafficRevenue - www.trafficrevenue.net
They pay for 20 countries and offer very high CPM rates like over $2.00 CPM for USA. Already got paid by PayPal. If you are looking to start earning from your website, give them a chance.
I am sorry If I posted at the wrong section.
