Hey guys, My ad is on the first position on google for a certain keyword, and my average all time cpc is $.16 for that keyword but recently i've been targeted by click fraud. The person doing this is very smart and knows how to bypass google invalid click detection. This guy is most likely using different Ip's for each click. I've lost already $5,000 from fake overpriced clicks from this guy. I contacted google about this and they said that google whitewashed all invalid clicks but I know this isn't true because my cost per click goes up to $7-15 per click when this keyword has over a couple hundred clicks at $0.16. The person strikes me in intervals, sending me thousands of dollars of fake clicks at a time (my daily budget is high). Google whitewashes most of these clicks but a lot of clicks stick and do not get whitewashed. Google doesn't seem to think any of these clicks are fraud but I do know that they are. I cant trace the persons IP since he uses a new one for every fake click to my ad. Any suggestions? Thanks for reading.
