Adsense High Paying Countries List

for me UK is the best ..
may be high currency value must be a reason.
1 pound> 1 US$

 

I never heard Guyana, but Switzerland sounds promising, I should give it a try, must need multi-language website for this I assume.

 

usa and Uk i prefer

 

Is there any difference if the traffic is targeted on "All countries"?

 

I'm always target my traffic from US and Europe
