Shuman Ghosemajumder, Business Product Manager for Trust & Safety, is back with a quick update on invalid clicks:

Those of you following AdWords may have noticed that we've been trying to tell advertisers more and show them more about invalid clicks. We also think there is more the industry as a whole can do to promote transparency on the issue, which is why we're participating in the Industry-wide Click Measurement Working Group. The effort is coordinated by the Interactive Advertising Bureau (IAB) and Media Rating Council (MRC) with a goal of developing "a detailed definition of a 'click' and the standard against which clicks are measured and counted including the identification of invalid clicks and/or fraudulent clicks."

More information about the announcement can be found in the press release from the IAB.
