Google Detect Invalid Clicks


The security of Google AdWords advertisers is important to Google, and we have dedicated a number of resources to protect your account against invalid activity.

Google has three powerful tools for protecting clicks on AdWords ads:

Detection and filtering techniques: Each click on an AdWords ad is examined by our system. Google looks at numerous data points for each click, including the IP address, the time of the click, any duplicate clicks, and various other click patterns. This detection and filtering occurs over a number of levels including the following:
- Real-time systems filter out activity fitting a profile of invalid behavior (such as excessively repetitive clicks)
- Clicks and impressions from known sources of invalid activity are automatically discarded


Advanced monitoring techniques: Various unique and innovative methods are applied at each stage of the filtering process, thereby maximizing proactive detection of invalid activity.

The Google Team: In addition to our automated click protection techniques, we have a team that uses specialized tools and techniques to examine individual instances of invalid clicks.
