Google CEO Eric Schmidt recently revealed that he clicks on Google ads "all the time." Asked at the Search Engine Strategies Conference earlier this month "When was the last time you clicked on an ad, and why, at Google?" Schmidt acknowledged:

I do it all the time, probably because I want to make sure that everything was working.

Are such evaluation clicks by the Google CEO registered by Google as "invalid clicks" and filtered out before advertisers are billed? Or, are Google advertisers charged for a click each time Schmidt clicks on a Google ad under the guise of making sure that "everything was working?"
