What is Google-Safety?

Google-Safety is Google's ads checker. It checks landing pages submitted as ads.

The operator's description: Abuse-specific crawling, such as malware discovery; ignores robots.txt. (developers.google.com)

How do I block or allow Google-Safety?

Google-Safety has no robots.txt token of its own. Google says it does not follow robots.txt. Controlling its access means recognising its verified identity at the edge (CDN or server).

How do I see whether Google-Safety visits my site?

In your server or CDN access logs, look for Google-Safety in the user agent. Google Analytics does not show these visits: agents do not run its JavaScript.

Anyone can copy the name in a user agent, so counting log lines is not enough. Knocklog reads your site's traffic on any host, confirms who is who, and shows how often Google-Safety came, which pages it read and what that brought you.

How do I know it is really Google-Safety?

Google publishes Google-Safety's IP addresses at https://developers.google.com/static/crawling/ipranges/special-crawlers.json. A visit that claims to be Google-Safety from outside those ranges is spoofed.

The IP's reverse DNS, confirmed forward and back, must end in .google.com.

Knocklog runs this check on every visit and separates the genuine agent from impostors.
