Thank you for sharing this useful information. Is good to see which are the differences in earnings from US traffic and non US traffic.
you focus on US & India. use correct keyword & channel for other countries. what is the time period of this ad ? i mean one month, day or year. what is the pages? is it page view or your web pages? what is your website?
its march 2010 traffic. Adsense impressions 1,432,170 and clicks 27,571. My website is a search engine
Yes for sure US traffic pays more so we have ti target traffic from US mostly to get high click rates ....
I dont think its a good idea to tell my website because when someone click the ads 20 times, then my adsense will get banned.
