What is Google-Read-Aloud?

Google-Read-Aloud is Google's assistant acting for a person. It fetches a page because someone asked an AI assistant a question right now. Each visit is a person waiting for an answer that may mention you.

The operator's description: Fetches a page when a person asks Google to read it aloud. (developers.google.com)

How do I block or allow Google-Read-Aloud?

Google-Read-Aloud 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-Read-Aloud visits my site?

In your server or CDN access logs, look for Google-Read-Aloud, google-speakr 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-Read-Aloud came, which pages it read and what that brought you.

How do I know it is really Google-Read-Aloud?

Google publishes Google-Read-Aloud's IP addresses at https://developers.google.com/static/crawling/ipranges/user-triggered-fetchers.json, https://developers.google.com/static/crawling/ipranges/user-triggered-fetchers-google.json. A visit that claims to be Google-Read-Aloud 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.
