Does it make any different from which country the clicks on your adsense is from? I can imagine there is much more competitions for advertisers to place their ads in US for example. Will that make clicks from visitors from the US give me more money?
Yes of course there is a difference. click from US traffic pays you more when compare to other clicks from other countries
Well, I think there's no difference. I think all users from all countries have same value. EDIT: I ment, they get same money for same clicks...
