Create a Correct Robots.txt File

A robots.txt file gives compliant crawlers instructions about the URLs they may request. This generator focuses on standardized and widely supported directives: User-agent, Allow, Disallow and Sitemap.

Control crawlers

Create rules for search crawlers, image bots, AI search crawlers and model-training crawlers.

Validate rules

Find missing groups, invalid paths, unsupported noindex directives and dangerous site-wide blocks.

Test URLs

Test important paths against crawler-specific groups and longest matching rules.

Where should robots.txt be placed?

Upload robots.txt at the root of the exact hostname and protocol it controls. A file at www.example.com does not automatically control shop.example.com. Serve it as UTF-8 plain text.

Robots.txt is not security

The file is public. Do not use it to protect customer data, private documents or administrator pages. Use authentication, permissions and server-side access controls.

Search and AI crawlers

Googlebot and bingbot are search crawlers. Google-Extended controls certain Google AI uses. OAI-SearchBot relates to ChatGPT search, while GPTBot is an OpenAI training crawler. ClaudeBot is published by Anthropic.

Allow and Disallow

Disallow identifies paths a crawler should not request. Allow can reopen a more specific path. When multiple patterns match, compliant crawlers use the most specific matching rule.

Multiple sitemaps

You can include several absolute sitemap URLs. A sitemap helps discovery, but it does not override a Disallow rule or guarantee indexing.

Crawl-delay warning

Crawl-delay is not part of RFC 9309 and Google does not support it. This standards-focused generator therefore does not add Crawl-delay.

Important: Do not add Noindex to robots.txt. Use a robots meta tag or X-Robots-Tag on content that crawlers are allowed to access. If crawling is blocked, the crawler may never see the noindex instruction.

Robots.txt Generator FAQ

What is a robots.txt generator?

It creates a plain-text Robots Exclusion Protocol file from crawler groups and Allow or Disallow rules.

Can robots.txt remove a page from Google?

No. Blocking crawling does not guarantee removal from search results. Use a suitable noindex method when removal from indexing is required.

Does robots.txt protect private information?

No. Protect private information with authentication, authorization and server-side access controls.

Should I add Crawl-delay?

Only when a specific crawler documents support. Google does not support Crawl-delay, and it is not part of the standardized protocol.

Can I include multiple sitemaps?

Yes. Enter each absolute sitemap URL on a separate line.

How do I test robots.txt?

Use the validator and URL tester, publish the file at the website root, and verify important URLs with relevant search-engine tools.
