Fraud Blocker provides a solution that analyzes, detects and prevents your ads from appearing on websites and sources that we believe are invalid or fraudulent.

We do this by monitoring your inbound web traffic and looking for irregular behaviors of the sources that could indicate it's from a bot, non-human source, competitor, etc.

A few examples of this include :

  • Highly repetitive clicks in a short period of time

  • Sources that have misleading referral data

  • Users with "Headless browsers" that don't have a graphical interface

  • Mismatched countries of origin

  • Traffic sources that may have been on your website for less than a second, such as from accidental clicks.

  • VPN, TOR or other privacy-enabled servers that bots can often use to hide their identity

  • Importing IP blacklists from public sources such as

  • An unusually high ratio of IP addresses for a single visitor's device

  • And much more

Here's a visual example of our detection system:

We record the IP address, device ID and other fingerprints for each traffic source to your website and their "fraud score" increases if their behavior matches any of the irregular ones noted above. Once their score passes 7 (out of 10), we consider that source to be invalid (or fraudulent).

We then pass the corresponding invalid IP addresses to the "IP exclusion list" in your Google Ads account in near real-time. You can view these in your Google Ads account here:

We update these frequently and you can view the history of these updates in your "Change history" tab in your Google Ads account:

We currently integrate directly with Google Ads, however you can download the bad IPs directly from your Fraud Blocker dashboard and import those to most other advertising channels you may be using such as Bing Ads, Ad Roll and more.

This prevents your ads from serving to sources that we believe are invalid or fraudulent.
