Fraud Blocker detects and then blocks a fraudulent IP in <2 mins, on average.
This is the time it takes from when an IP is first determined to be fraudulent/invalid, to the time it appears in your Google Ads exclusion list.

In addition, we run a parallel sync script for clicks that happen very quickly, such as a competitor clicking on your ad many times. This parallel system allows us to sync quickly without having interference from syncing to other client accounts or for other types of fraud.
