What is Google-Agent?
Google-Agent is Google's agentic browser. It navigates, clicks and fills in forms in a browser on behalf of a person, for example to compare offers or book something.
The operator's description: Agents hosted on Google infrastructure that navigate the web and act on user request.

How do I block or allow Google-Agent?
Google-Agent has no robots.txt token of its own. Google does not say whether it follows robots.txt. Controlling its access means recognising its verified identity at the edge (CDN or server).
How do I see whether Google-Agent visits my site?
In your server or CDN access logs, look for Google-Agent 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-Agent came, which pages it read and what that brought you.
How do I know it is really Google-Agent?
Google signs Google-Agent requests with Web Bot Auth (HTTP message signatures, RFC 9421) from https://agent.bot.goog. A valid signature is the strongest proof of identity.
Google publishes Google-Agent's IP addresses at https://developers.google.com/static/crawling/ipranges/user-triggered-agents.json. A visit that claims to be Google-Agent from outside those ranges is spoofed.
Knocklog runs this check on every visit and separates the genuine agent from impostors.
