I am seeing multiple clicks from some visitors to my site. it looks like they click on my ad, check out my site then hit the back button to the search results and then click on the ad to go back to my site again. this sometimes happens 3 or 4 times from some visitors.
does google charge for these types of clicks? if so it gets kind of expensive.
