is it normal to see earnings decreases after awhile?

i saw my earnings about $2.34 today but after about 3hours i check it again and it is now $2.32. i know its just cents but why is this happening?

 

It is an estimated earning so it is not a final one!

I think this is the reason!

 

i've also experienced that one, i think Google removes the revenue you've got from an invalid click.. oops... that's only an opinion

 

I've seen the same happen to me, although they only deducted 1 cent from my account
I think it's due to the estimated earnings thingie not doing its job too well

 

it's normal .

 

Your earnings are estimated earning. So it can always change a bit but not that much.

 

They fluctuate, sometime quite a bit over days and even weeks.

 

You will definitely find that they fluctuate ALOT. There are so many factors all in play.
