E-commerce Insights: All You Should Know About Click Fraud

Catalogers and other search advertisers are justly concerned about click fraud. Click fraud is when a person (or computer) imitates a legitimate user clicking on a pay-per-click ad, without actual interest in the ad’s target.

Like Justice Potter Stewart’s definition of pornography — “I know it when I see it” — click fraud escapes precise definition. To know when a click is fraudulent, one needs to know the clicker’s internal motivation for clicking or be able to prove the clicker was an automated ’bot. Most experts agree that few individual clicks are “good” or “bad.” Instead, investigators assign quality scores that indicate the probability that a click is legit.
