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 our fraud detection system:

  • 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 and device fingerprint for each visitor 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).

How we block ad fraud on Google Ads

We pass the invalid IP addresses that we detect 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:

How we block ad fraud on Meta Ads

Meta Ads does not have "IP Exclusions." So instead, we create a "Custom Audience" and exclude those from your Facebook campaigns.

When a user clicks on your Facebook or Instagram ad, we collect an Audience ID and monitor the behavior of those users similar to how to track IP addresses and device fingerprints. We then add any bad users based on their audience ID to your audience exclusion list in real-time.

You can view the Custom Audience we create inside your "Audiences" tag in your Facebook Ads Manager:

You can then see the Custom Audience added to your Exclusion targeting in your Facebook Ads account under your "Ad Sets" here:

How you can block ad fraud on other platforms

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