How much of the total clicks you get from PPC adwords is rated as fraud by Google for which you don't have to pay ?
This is the questions I get asked most often "what about click fraud?" most people asking have never even used AdWords
click fraud is not a big factor as we assume 3-4% clicks invalid when launching campaign big question is conversion/clicks
great news for someone just opening their business up to adwords. Still haven't seen any conversions, so probably won't stick around with it much longer regardless.
