Robots.txt and llms.txt analyzer

Check whether your robots.txt and llms.txt files give crawlers and AI agents clear, useful discovery instructions.

When to use this tool

Crawler discovery

Confirm crawlers can find your sitemap and are not accidentally blocked.

Agent browsing

Check whether llms.txt has a clear Markdown summary and useful links for AI agents.

Before Search Console validation

Use this before requesting validation or submitting new pages for indexing.

What the result means

Read it as crawler access, not SEO magic.

Use this result as a discovery-file sanity check. It does not replace content quality, rendered HTML checks, or Search Console validation.

It does not promise rankings, traffic, or AI citations. It tells you whether bots are getting useful HTML from the request path.

Watch first

Low readable text, missing title or H1, failed bot checks, or a large raw-versus-rendered gap.

Good sign

Bots receive enough readable content, important metadata is present, and the page does not depend on a blank shell.

Common warning signs

Very low readable text, generic metadata, missing headings, blocked crawler access, or a large raw-versus-rendered gap.

Next step

If discovery files are missing or unclear

Add a simple robots.txt with a sitemap reference and an llms.txt file with clear Markdown links to important pages.
