My adsense total sais i have a total of 4,5 ctr tough my site that brings in 90 % of the impressions only has 2,5 % ctr,and the rest has ctr's ranging from 2 to 4,8 . Is there sometimes a error in the reports,or what is it?
That is where traffic research plays an important part. Learn, repeat; learn, repeat; learn, repeat...
i think there is a error because,when i use a calculator and add up every earning per site,its not the same amount.
