Over the past few months, we've provided answers to your invalid click questions. Now, Shuman Ghosemajumder, Business Product Manager for Trust & Safety, is back to provide details on a new related feature.

Today, we’re announcing the launch of a new AdWords feature enabling advertisers to have a much more detailed picture of invalid click activity in their account. The metrics of “invalid clicks” and “invalid clicks rate” will show virtually all the invalid clicks affecting an account.

These clicks are filtered in real-time by our systems before advertisers are charged for them. The resulting data will of course differ from one advertiser to the next. In addition, a much smaller number of invalid clicks may also be credited to advertisers’ accounts after-the-fact, as the result of a publisher being terminated from the AdSense program for invalid click activity. These will appear as account-level credits.

One of the most controversial issues related to the topic of click fraud has been estimating how big the problem is. Estimates from third-parties (usually from consultants who have a financial incentive to make the problem seem very large) have been both inconsistent and greatly exaggerated due to their methodologies. Advertisers have always been able to compare their log data with their AdWords charges to calculate an estimate of the number of invalid clicks in their own account. This new tool will make estimating invalid click activity much easier.

Remember, when we determine that clicks are invalid, you aren’t charged for them, and they don’t affect your other campaign statistics. You may include the invalid clicks and invalid click rate columns in yearly, quarterly, monthly, and daily reports. More information about the new reporting can be found here.

Update: Changed to reflect the fact that monthly, but not weekly, reports are available at this time.
