In Meta Ads, you can prevent specific visitors from seeing your ads by adding them to a custom audience and excluding that audience from your ad sets through updated targeting specifications.

ClickGUARD blocks visitors in Meta Ads through a sophisticated process that leverages custom audiences and automated targeting exclusions. Here’s how it works:

1. Custom Audience Creation: During the initial setup of ClickGUARD, a new custom audience is created within Meta Ads. This audience is specifically designated for collecting visitors who exhibit suspicious or fraudulent behavior.
2. Rule Activation and Event Tracking: When an ad click triggers one of ClickGUARD’s predefined protection rules—such as detecting patterns indicative of click fraud—an event is sent to Meta Ads to identify the visitor responsible for the suspicious activity.
3. Visitor Inclusion in Custom Audience: The identified visitor is then added to the custom audience created by ClickGUARD. This custom audience serves as a blacklist for undesirable traffic.
4. Automatic Exclusion from Ad Sets: Since this custom audience is excluded from your ad sets, visitors included in it will be automatically blocked from seeing your ads in the future. This is achieved by updating the targeting specifications of your ad sets to exclude the custom audience, preventing these flagged visitors from interacting with your ads again.

By utilizing this approach, ClickGUARD effectively manages and filters out invalid or fraudulent traffic, helping to protect your advertising budget and optimize the performance of your Meta Ads campaigns.
