What does this LLMs.txt Validator check?

It checks whether your pasted llms.txt content has a clear title, summary, website URL, audience, language, useful sections, valid-looking URLs, and common issues that make the file harder for AI systems to understand.

Does this validator fetch my website?

No. The first version runs fully in your browser and validates the text you paste. It does not crawl your website, call an API, or store your file.

Can this validator guarantee AI search visibility?

No. LLMs.txt is an experimental practice. This validator helps you catch structure and clarity issues, but it cannot guarantee ranking, crawling, citation, or AI search visibility.

Frequently Asked Questions

Does this validator crawl my website?

No. This version runs in your browser and checks pasted text only. That keeps it free, fast, and privacy-friendly.

What score should I aim for?

A score above 80 usually means the file has the basic structure needed for a first publish. A lower score does not mean the file is harmful; it means there are clarity or completeness issues to fix.

Can a valid llms.txt improve rankings?

No tool can guarantee rankings or AI citations. Treat llms.txt as an extra clarity layer on top of normal SEO basics such as crawlable pages, useful content, schema, robots.txt, and sitemap.xml.
