Positive roi?
Some industry forces argue that click fraud isn't a significant problem, claiming that if advertisers didn't get a positive return, they wouldn't invest in PPC. Yet PPC continues to grow, so click fraud must not be a significant problem.
But the truth of the matter is, there's not a single CEO out there, who if presented with the prospect of saving even two percent on his spend, wouldn't want the protection to know that he's not spending that money unnecessarily.
