What llms.txt means
llms.txt is a community proposal, similar in spirit to robots.txt, meant to help large language models find a site's most useful pages. It is not an official standard, and major AI providers have not confirmed they rely on it. It is cheap to add, but it is no substitute for clear content and structured data.
Why it matters for your website
Some site owners add llms.txt hoping AI tools will understand their site better. It is still only a proposal, and major search engines have not said they use it, so it should not replace good content, clean HTML and normal SEO. Knowing that keeps you from spending money on it as a shortcut.
A software consultancy adds an llms.txt file listing its service pages and documentation links in plain Markdown. It treats the file as a low-effort extra, not a ranking plan.
Tips
- Focus first on clear, crawlable pages, since that is what search engines and AI tools rely on today.
- If you add llms.txt, keep it short, accurate and updated when key pages change.
- Treat claims that llms.txt boosts AI visibility with caution until platforms confirm they use it.
Common mistakes
- Paying for llms.txt services that promise better rankings or AI citations.
- Confusing llms.txt with robots.txt, which actually controls crawler access.
