I really loved this kind of post, if I have your permission may i duplicate this post to my blog and share it with other people as well. Naturally I'm going to give the original credits to you only.

After promoting the hell out of them and delivering a site that actually got page clicks, google deauthorized my account and confiscated the measly earnings without telling me why. Bleh. Despite the sour taste that this left in my mouth

Really impressive thing here you shared.

CPM advertising refers to cost per Thousand (1000). Earn for every thousand times an advertisement is displayed on your website or blog. It's an impression basis paying system which is widely used advertising networks online in today's time. We have seen many websites that has good traffic but do not make much money from ads. This is because of they have maximum number of returning visitors on their site and obviously most of them won't click on ads as they know already. For those websites, CPM is the right kind of ads to convert that traffic in to revenue. The top lists of cpm advertising networks are given away below.
