I hate to admit it, but you have to give credit where it is due. I have been following just one keyword but it may apply to others. Google has only charged me for one click in the past 7 days when the suspicious clicks for that keyword are at least 10 to 15.

I think I know what click behaviour is ignored by the Adwords software (i.e. not charged to the advertiser) but I am not going to spell it out here.

What is it with Arrow Sheds? They’re probably OK, if you are into sheds, but these “arrow shed” searchers just like to click my ads but they don’t buy anything. This Comcast visitor from Nashua, NH is a good example of the 2-3 daily clickers who visit my site every day. At least he made an effort to click deep into the site before going back to the Google SERP and clicking the ad four times.
