I’ve seen several discussions here about landing pages, tracking domains, and campaign URLs getting hit with Google Safe Browsing warnings.
We dealt with the same issue in our own campaigns. The biggest problem wasn’t only the warning itself - it was discovering it too late, after traffic had already been wasted or, in some cases, the traffic source had already restricted or temporarily frozen the advertiser account.

Unlike a general website-monitoring tool, FlagDetector is built specifically around paid-traffic campaigns.
It can:
- Connect directly to supported ad networks and automatically sync campaigns every hour, adding or removing them as their status changes - no manual link updates required
- Add and monitor URLs manually, without connecting a traffic source
- Continuously monitor URLs for Google red warnings using multiple detection methods
- Detect broken or unavailable links, including 404 errors, connection failures, domain configuration issues, and similar problems
- Send immediate alerts when an issue is detected
- Optionally pause affected campaigns automatically before more
