heellloo i just read and analyze one of the thread that said $4 for just 2 clicks..and i was quite suprised that per click can also generate a dollar and i also read that US and UK ...(click from this country gives more revenue) is that correct??? i mean does pay per click differs from country to country??????
Of course cost of click depends on country. In AdWords advertisers can set geo targeting... However in UK click are expensive enough... I think in your case the cost depends on niche...
A niche is a market that you target. For instance "health" is a niche. "Weight-loss" would then be a sub-niche. Hope that helped
Quite obviously. Why or earth would an advertiser pay the same amount for a US customers click and someone from a country where an average person earns less than a USD per day? It varies a lot from country to country, and across the keywords. Same us user can get you $0.01 or $5, depending on the keyword. That doesnt mean that targeting high paying keywords is better, low paying niches would most likely get you more traffic to compensate for the per click value.
Adsense earning is different with different countries. So how much click and how much earning is different in different situation.
