## How to block Google-Read-Aloud in robots.txt

Google says Google-Read-Aloud does not follow robots.txt, so a robots.txt rule won’t stop it. Block it at your server or firewall by user agent, and by IP if Google publishes its ranges.

Add <meta name="google" content="nopagereadaloud"> to a page to opt it out of Read Aloud.

## How to verify a request is really Google-Read-Aloud

Anyone can send any user agent, so the string alone proves nothing.

Google publishes the IP ranges Google-Read-Aloud crawls from. A request that claims to be Google-Read-Aloud from any other address is not Google-Read-Aloud.

Or check by reverse DNS: look up the hostname of the request’s IP, confirm it ends in `google.com`, then look that hostname up again and confirm it points back to the same IP.

## See when Google-Read-Aloud reads your site

Bots don’t run JavaScript analytics, so a script tag never sees them. invisit records crawler reads on the server instead, through its server SDK or a Cloudflare Worker, and shows which bots read which pages, next to your visitors.
