Back in December, I caused quite a storm, when I published data from Google’s Shuman Ghosemajumder that suggested Google’s click fraud rate was less than 2% (and actually less than 0.2%).
Speaking with Ghosemajumder last week, it appears that story helped form Google’s strategy for coming clean on the actual numbers for click fraud.
Google has now confirmed that user-identified click-fraud (the clicks not already filtered by Google) is actually less than 0.02% of all Google clicks. In addition, the average rate of invalid clicks (Google’s term for clicks that are filtered automatically and not charged to advertisers) is less than 10% of all clicks.
Not publicized by Google – but I certainly stressed to them they should make a deal of – is that their click fraud numbers are vetted and audited by an outside company. These numbers are not just plucked out of the air by Ghosemajumder.
