I'm currently using AdWords for my business advertising. Can anyone person click more then once, for example they click on my ad 2-10 times in one hour will i still get charged from that one person or am I charged by every unique person who clicks? Thanks
Not sure,but I Think it goes by unique click.Once they click their info is recorded and they cannot get credit for clicking again.
google has methods of spotting invalid clicks. Using IP address etc and click patterns. You may have a genuine user searching for a type of service and look through a number of different ads and may click on yours twice. In this case you may be charged twice. But if it is a competitor coming back every day and clicking on your ad 10 times google should spot this and reimburse the click costs to your account.
if you click on a Ad then your click on the same ad within 30 days from the same computer/browser is treated as invalid click... then you are protected from click fraud...
