A class action lawsuit was filed in US District Court against Google alleging breach of contract, negligence, unjust enrichment, and unfair business practices-all involving charges of click fraud. A click fraud protection firm, filed the suit in California in the name of an unknown number of plaintiffs for an amount not less than $5 million
Click fraud is the term used in the Internet search industry to describe the practice of clicking on search advertisements to run up the costs on advertisers.The lawsuit claims that since 99% of Google's revenue comes from advertising, Google has a huge financial interest in doing little about the instance of fraudulent clicks and criticizes the search giant for failure to disclose its own estimate of the number of fraudulent clicks.
The suit falls just short of accusing Google of physically performing the click fraud itself. The most visible allegation is the charge of negligence on the part of Google, claiming that Google isn't doing enough to prevent the problem.
