If you are reading this page, then you have most likely seen the following User Agent in your web logs:

User-Agent: SCREENED UNPAID CLICK - ValidClick - More Info at: (http://www.validclick.com/screened_click.php)

The reason you have seen this user agent in your web logs is because you are advertising on a PPC search engine that is using ValidClick's real-time click fraud detection technology to ensure clicks to your website are from actual users and not generated by bots, scripts, or other forms of automated clicks.

Each time you see the above user agent in your logs, ValidClick found a click that it either found to be automated or was highly suspicious of being fraudulent. ValidClick then passed the user to your home page and bypassed the PPC search engine ensuring that you didn't get charged anything for the suspicious click.

If you would like to know more about our products or use ValidClick to protect your own advertisers from click fraud, please feel free to contact us at your earliest convenience.

Thank you for visiting our site and please assist in the fight against automated click fraud.
