robots.txt token: Google-Extended

## What is Google-Extended?

Controls content use for Gemini training and grounding; it does not control Google Search inclusion.

## How to identify it

This is a policy identifier, not a distinct HTTP crawler. Do not use it to infer visits from access logs.

## How to check identity

Not a request identity: there is no separate crawler to authenticate.

## Access and robots.txt

A robots.txt policy token, without a separate HTTP user agent.

Optional full-site opt-out; merge with existing rules only if intended. Not a security control.

```text
User-agent: Google-Extended
Disallow: /
```

## What it means in your analytics

Do not create a request count for this token. Use ordinary Google crawler observations and review content-use policy separately.

## Useful measures

Published robots.txt policy; Underlying crawler requests.

## What to check next

Audit the robots.txt policy itself. A zero count for this name in access logs cannot confirm whether the policy is active.
