About the blocklist

Click True maintains the most complete and accurate list of web sites that deliver fraudulent or low-value clicks to internet advertisers. Our current list contains over 5,000 web sites and is growing rapidly. Using our patent-pending FraudFinder ™ web crawler, we are able to automatically identify and screen possible click-farms and other "made for AdSense" web sites. Clicks from web sites on our master blocklist are automatically flagged as low-value clicks. However, our unique click quality reports allow you to easily create and maintain you own custom block lists based on data from your own campaigns.

Using the blocklist

Advertisers within Google's AdSense ™ network and Yahoo! Sponsored Search can easily import our blocklist into their existing campaigns and watch their advertising costs drop dramatically. Google allows up to 500 sites for each campaign. Our simple reports allow you to see which sites are generating low-value clicks and easily add them to one or more blocklists. Simply copy and paste the URLs from the blocklist directly into the site exclusion list within your Yahoo! or Google AdWords campaign settings.
