Ok, so my ESTIMATED earnings for September was $1400 but currently I'm only being paid $600. Can anyone comment on the big difference between the estimate and actual amount?
The difference betwen estimate and actual amount for me were from a couple of euros to 60 euros but that is not a problem because that difference may come from invalid clicks or something like that.
Most probably Adsense sees the click as click fraud or traffic quality is extremely low (bounce right after they click on ad). With such a huge difference between estimate and actual earnings, I would not be surprised if Adsense finds your account of too low quality and bans you.
This is huge difference, its mean you got lot of invalid click! I only see 2 or 3 Cents difference in my estimate and final earnings.
yes it's a huge difference! I never noticed any difference between what i thought i earned and what i've been paid, but you can only notice such a difference
Check Payment page carefully, It may be possible that you got $600 money from August 2010! You Sept money will be issue around Oct 25!
