How can I report an inappropriate Google ad that I saw on a site?

Please know that the ads displayed in our content network are reviewed according to our AdWords advertising guidelines. While we make every effort to ensure that ads which may violate our policies do not run prior to review, some ads may run on Google before our AdWords Specialists check them.

If you see an inappropriate ad, we ask that you please report the ad to us through one of the following:

Report the ad directly to our AdWords team using this form. Please include as much information as possible to help us locate the ad, such as the display URL, the destination URL, and the ad text.
Click on the "Ads by Google" logo on the unit containing the inappropriate ad. Using this link will flag the ad for additional review, and will also allow us to review your comments and suggestions to help us improve our AdSense program.
All AdWords ads are held to the AdWords Editorial Guidelines and Terms and Conditions. If this ad is found to be in violation of any of these policies, our AdWords Specialists will take the appropriate action.

If you saw the inappropriate ad on your own site, in addition to reporting the ad to us, you can also prevent the ad from displaying on your site again by using your Competitive Ad Filter.
