SEO and GEO
llms.txt
llms.txt is a proposed standard file placed at a site's root that gives AI systems a clean, curated guide to the site's most useful content.
Why it matters
AI systems do not always parse a full website cleanly, and important pages can be missed or misread. An llms.txt file offers a simple, machine-friendly map of what matters, in one place. For a company that wants answer engines to understand and cite it correctly, it is a low-effort signal that supports GEO.
How it works in practice
llms.txt is a plain text file in a simple format, placed at the root of the domain, that lists the site’s key pages and sections with short descriptions and links. It is written for machines rather than people, giving AI crawlers a curated path to the content that matters most. It complements, rather than replaces, a sitemap and structured data.
Common mistakes
A common mistake is treating llms.txt as a guaranteed ranking factor rather than an emerging, voluntary signal. Another is letting it drift out of date as the site changes. A third is listing everything instead of curating the genuinely useful pages.
How hubsell approaches it
hubsell publishes an llms.txt file that maps its key pages, including this glossary, so AI systems have a clean guide to the content worth citing.
