Improper Calculation??

May 1, 2010 - May 31, 2010 Earnings Details

Total Monthly Earnings $x,xxx.xx (160$ less than the original estimated earnings)

But when I check my previous month earning records;

Last Month - May; Total estimated earnings $x,xxx.xx

--------

May I know what's this error?

 

Well, you should understand what "estimate" mean....it is estimation, not the actual

 

I am amazed since its happened for the first time. Never my original earnings and estimated have been different. :-|

 

Most of the time they will be same but sometime they might have some different (normally will only be less, never more)
This happen normally when adsense pull back some cost due to invalid clicks

 

yeah right, I have never seen any difference too!

 

Ya, it never change. contact support.

 

But they don't notify you for invalid clicks chargeback? Are you sure this is due to invalid clicks?

 

The computer is never wrong ;-)
