Adsense methodology for good cpc

Hi
I have researched that if you have a good website with good pagerank and backlinks and good visitor from search engine then google adsense appear top paying ads on your webpage and if you have started new website and there is nothing and you have placed good paying adsense keyword based compain on your website but remember all low cast adsense ads will appear on your site and you will earn in cents only.

what you have experience please share

 

there may be some truth to that in that you're more likely to receive better quality ads with older, better pr sites, but I've had $x clicks on brand new sites as well.

 

but how cooperdev ..... How it you have earn $x ??? I want to learn

 

I am still looking answer, if you have any tip then let me know here or pm

 

if you have the right niche - health/legal/finance it's pretty easy.

 

Your theory could be true but not entirely. Established sites could be targeted by advertisers and that's why getting better quality ads and higher paying clicks. However it's not always like that.
