Ad Clicks not counted?

I was looking at my adsense account for two days in a row, the first day I had six clicks (yes, I know it's sad, thats not the point) and the next day I had nine clicks, but the estimated earnings didn't increase.... Why is this?

 

Invalid clicks

 

How are they invalid?

 

possibly the same ip range clicking too many times on ur site around the same time.

 

so my visitors aren't allowed to click more then one ad? but I can't tell them not to.... I can't mention the ads to them.... what a quandary.

 

No they are allowed but not click your ads at the same time.

 

most of the invalid and auto click wont be counted

 

I get people clicking two at the same time, that can be accidental, but auto click? where did you get that from?

 

Well simply the advertiser paid less for the click.
