Last night, I logged into my account and got 4 clicks on one channel, but the total clicks say I got 40. Up until now my clicks are 35+ clicks more. The total earnings are accurate though.
Are you saying that you have clicks that aren't in your channels? Have you made sure you have channels set up for each place you've posted your pub-xxx?
You've most probably just missed a channel somewhere, but what I did when that happened was to tell Google get incase someone else was using my pub-xxx.
I don't think someone is using my ID. My earnings are accurate. Sample data: Total: 60(clicks) - $2.50 Channel 1 - 10(clicks)- $1.00 Channel 2 - 10 (clicks)- $1.50
