About the Ad Traffic Quality Resource Center
The relationship between Google and AdWords advertisers is built on trust. Advertisers rely on the relevance of our ad placement, our reporting statistics, and the quality of the clicks their ads receive. We take this trust seriously, and we know that AdWords couldn't exist without it.
To stay on top of your concerns, we keep a close eye on online advertising journals and blogs. We've seen that many of you have questions about click fraud and the impact it might have on your AdWords accounts. In particular, we've heard your concerns about 'click farms' and the quality of clicks received on the content network. To help address these issues, we've created this website to aggregate various resources on click fraud.
We hope that you find this resource center useful. We're still working on expanding the website and are eager to incorporate your feedback. Feel free to pass along your suggestions on how it could better suit your needs.
