Responding to concerns about click fraud in the online-ad industry, Google will be revealing to advertisers the number of invalid clicks on their ads.

With changes the company is set to make to its AdWords system late Tuesday, advertisers will be able to see the number of invalid clicks Google found, as well as what percentage that represents of total clicks registered, said Shuman Ghosemajumder, business product manager for trust and safety at Google.

Click fraud occurs when Web site publishers click on ads on their site to boost their revenue or when companies click on rivals' ads to eat away at their advertising budgets. Invalid clicks, for which Google does not charge advertisers, include inadvertent double clicks on an ad, according to Ghosemajumder.
