Tweet

I have been earning from Google Adsense, however, it takes around 2-3 months every time I reach the maximum payout of $100. I am just wondering, for those who use adsense, what is the best location of adsense on the blog that earns the most? If you can, please check my blog and make some suggestions about the placements of the ads - http://www.printmoney101.com/
