Webzio-Extended — Webz.io AI data opt-out

Webzio-Extended is a robots.txt token Webz.io provides so site owners can control whether their content is used for AI-related data products. Webz.io operates web-data crawlers; where a specific is thin, it is marked partially verified rather than guessed.

Partially verified

What this means

Webzio-Extended is a robots.txt token Webz.io provides so site owners can control whether their content is used for AI-related data products. Webz.io is a web-data company whose crawlers gather public content; this token layers an AI-data control on top of that activity.

Where Webz.io's public documentation is thin on a particular specific, this entry describes the control pattern and avoids asserting details that cannot be confidently sourced. It relates to the older Omgilibot lineage in the Webz.io ecosystem.

How to use Webzio-Extended

Webzio-Extended is used in robots.txt. To opt out of AI-data use site-wide, target the token:

User-agent: Webzio-Extended Disallow: /

This is a request Webz.io is expected to honour for AI-data use. As with all such tokens, robots.txt is a request to compliant systems, not an access-control boundary, and you should not invent IP ranges to verify related crawls.

How it appears in analytics and logs

Webzio-Extended is primarily a control token rather than a fetcher, so it signals an AI-data policy choice. Where Webz.io also crawls under other tokens, treat those crawl hits as bot events and the Webzio-Extended directive as a policy signal.

Diagnostic use case

Use the Webzio-Extended token in robots.txt to control whether Webz.io may use your content for AI data, separately from its standard crawling.

What WebmasterID can help detect

Because Webzio-Extended is a control token, it will not itself appear as bot events. WebmasterID can still help you observe any Webz.io crawl activity reaching your pages, which this token's setting does not directly change.

Common mistakes

Privacy and accuracy notes

Webzio-Extended is a robots.txt directive, so it involves no visitor data. It governs how Webz.io may use content for AI-related data products, which is a policy matter rather than an identity one.
