Bot protection for everyday ad operations
Detect Bot traffic using browser and browsing activity information. Review the reasons behind each detection, then use platform connections to address repeat ads to Bots.
Review why each visit was flagged. Share the findings with colleagues and explain them to clients.
Checks account for in-app browsers and shared networks used by real visitors, with additional safety checks before platform actions.
Review Bot detections and connection status in one place. Configure and check ad exclusions in each platform’s Ads Manager.

Detection combines browser, interaction and other signals. Additional safeguards are checked before ad exclusion.

The current Cloud Run configuration does not collect raw TCP TTL, TLS JA4 or HTTP/2 characteristics. These remain unavailable; evaluation uses observations that were actually collected. Legacy signal counts do not describe active new-Detector layers or coverage.
Safeguards protect whitelisted IPs, in-app browsers and shared networks from mistaken exclusions. Eligible exclusions added by AdFraud are removed during Google Ads sync. Connection errors and next steps appear on the Integrations page.
