After all, many non-converting clicks are not due to click fraud.
They could come from people simply browsing, not in itself fraudulent, but still bound to dilute ROI statistics.
Either way, as long as click fraud can be priced into the ROI (return on investment ) equation does it really matter whether the money is going to the search engine or the fraudster? Besides, arguably it is the search engine problem, as a lower ROI is likely to result in small ad spends coming their way for them to take their slice from.
What do you think?
My experience talking to Google’s front line Adwords reps gives me the impression that they’re sure they have adequate controls for click fraud. I’ve tried to escalate a couple of instances where I thought this might be the case and they simply assured me that that take measures to stop click fraud from happening.
Not sure I believe them entirely, but there’s no much we can do because it’s all secret.
