Hi. if some is getting fake clicks on his/her site and is sure he or she is not doing so in any way. What should be done or steps to take care of this matter. and how will google come to know its not me its somebody else.
As the above poster stated, Google tracks the clicks to the IP adress. If its not from yours, then you should have nothing to worry about. If you are seriously worried about the fake clicks though, shoot Google an Email to let them know whats up. Always be proactive.
