**Google-Extended** isn't a separate crawler. It's a name a website can use in [robots.txt](https://akkrev.com/glossary/robots-txt/) to tell Google whether content collected by Googlebot may be used to train and ground Gemini models.

## What it does and doesn't affect

- Blocking Google-Extended opts the site out of Gemini training use.
- It doesn't remove the site from Google Search.
- It doesn't control [AI Overviews](https://akkrev.com/glossary/ai-overviews/) or [AI Mode](https://akkrev.com/glossary/ai-mode/), which are part of Search and governed by Googlebot.

## For hotels

Most hotels want to be described accurately by Gemini, so blocking Google-Extended is rarely useful. As with every AI crawler choice, the risk is blocking by accident, through a template or plugin, rather than by decision.

## Why it matters for AI visibility

Google-Extended controls whether Gemini can train on your content. It doesn't affect Google Search, but it's worth understanding before you change it.
