German Traffic
 

What nationality of traffic is considered the most productive? I've heard that German traffic is the best. Is that actually true?

I've been thinking about launching a month long targeted advertising campaign with ero-traffic. So I figure the top five countries that I should go for should be Germany, Switzerland, Sweden, Denmark, and the Netherlands. Does this sound good?

What about Russian traffic how well does that convert?

add Belgium, UK, spain, Austria and France.
Second best might me Italy, Poland, etc.
But it depends on the payment methods & business model.

Russian is difficult.
