Google pays you based on what they get paid per click. Advertisers bid on ads based on key words, position, and competition. Google pays you part, they keep part for themselves.
Mostly affected by ur visitors area. Ofcourse it will pay big from outside asia. I've also tested. The sponsors and mrketers outside asia pay bigger then within asia. But content and visitors are also a power for ur huge amount. Take a look here www.full-masti.com will be a huge forum in the future.
