AdSense getting free clicks?

I just noticed something very strange in my AdSense account. I am showing 4 clicks on one channel today, but 0.00 earnings.

I have never seen this happen before. Any ideas? Or has anyone else ever seen this happen?

 

I noticed that before when someone from my workplace clicked on an ad. I assume that the click came from the same IP address as the IP that I occassionally log in from so there was no value for the click. I don't know if that is the case though.

 

Yes, if Google thinks the click is invalid, they record it as a stat, butyou do not get paid for it.

 

4 invalid clicks doesn't look good, you should keep monitoring your stats to make sure no one is sabbotaging your site.

 

Hmmm, well maybe that was it. This is the first time I have ever seen this happen. The channel in question usually gets several clicks each day. Of course, I know that no one clicked them from my computer and if the same person managed to click 4 of them that would be very unusual.

 

It could also be Public Service Ads (PSA) too. Those are free too.

 

That's invalid clicks or Public Ads (witch are free)

 

Thanks everyone, I appreciate the comments here very much. In the meantime I have received several more clicks on the same channel and the earnings are going up now.

 

don't worry i also have this one but when you put you link should be find a good website for put your link

 

it's really the advertiser that gets the free clicks.
i woke up to 6 clicks and zero cents.

 

i can think two think on your question . one of them is invalid clicks and andsense did not count this . the second alternative is public ads. are you sure that you are not recieving the public ads

 

who clicks on PSA's?even if the visitor is from turkey, wouldn't the PSA be in turkish?
it is just someone who clicks more then once and google doesn't charge for those clicks,some back clicks before going to the page, or it is cpm ads.

 

that must be invalid click avtivity

 

i guess then you work for google.
