Well, yesterday while checking my AdSense stat, I saw something very interesting (the number is not real...just to illustrate): Page impressions Clicks Page CTR Page eCPM [?] Earnings 1 1 100.00% $524.40 $0.52 I only got 1 click on one of the page tracked. And I noticed that Page eCPM is $524.40, but the earning is actually $0.52. It seems that google actually paying $0.52440 although it is rounded off during reporting... ...interesting although it dont actually mean much to the AdSense cheque. -- Well, on the other hand, although $0.00440 is dont mean anything to individuals like myself, I think it is a lot of money to Google. If you watched Sean Connery's Entrapment - you will see that those half a cent can mean a lot to big corporation. Imagine getting half-a-cent for every click!
