What is llms.txt and should you add it?
llms.txt is a proposed convention: a markdown file at your site root that gives AI systems a curated map of your most important pages and facts. Adoption by major engines is still limited and uneven, so treat it as cheap insurance, not a ranking lever — it takes about an hour, cannot hurt, and may help as support grows.
The idea mirrors robots.txt: a predictable location (/llms.txt) where a language model or its retrieval system can find a concise, plain-text guide to a site — what the product is, where the pricing page is, where the docs live — instead of inferring structure from navigation menus and marketing pages.
The honest status: it is a community proposal, not a standard, and the major engines have not committed to reading it. Some AI crawlers fetch it; whether it influences answers today is unproven. That means it should sit at the bottom of your AI visibility list, after the things with demonstrated effect — extractable facts on key pages, structured data, third-party citations.
If you add one, keep it short and factual: product name and one-line description, pricing summary with real numbers, links to pricing, docs, security, and comparison pages, and a last-updated date. Regenerate it when facts change — a stale llms.txt is worse than none, because it hands engines outdated facts in the most convenient possible format.
