An llms.txt file at the site root helps agents locate your most-important content.
Agents check /llms.txt first to find your canonical docs, pricing, API, and policies. Without one, ChatGPT, Claude, and Perplexity have to guess from your homepage and follow whichever links land first, usually marketing copy, not the source of truth. Sites with a well-formed llms.txt show up cited in agent answers; sites without get summarised.
Underlying specification: https://llmstxt.org
- Pick a preset on the AgentSpeed llms.txt generator (SaaS, ecommerce, agency, docs, marketplace, or API product).
- Replace placeholders with your real brand, tagline, description, and link URLs.
- Add a Docs section with at least a quickstart link, plus Pricing, Support, Policies, and Changelog as relevant.
- Publish at https://your-domain/llms.txt as text/markdown.
- Make sure /llms.txt is not disallowed in robots.txt. The file exists specifically so agents can read it.
The snippet below uses your-domain.example as a placeholder. Replace it with your actual host before deploying. For a fix tailored to your live site, run a scan and open the per-domain remediation page.
What is /llms.txt?
A markdown file at the root of a site that tells AI agents which pages are canonical. The format is defined at llmstxt.org. AgentSpeed scores its presence and structure as part of the discoverability sub-score.
Is /llms.txt the same as a sitemap?
No. sitemap.xml lists every URL for search-engine crawlers. /llms.txt is a curated list of citation-worthy pages for LLM agents, typically docs, pricing, support, policies, and changelog. They serve different audiences.
Will publishing /llms.txt help my SEO?
Indirectly. /llms.txt is read by AI agents (ChatGPT, Claude, Perplexity), not by Google. Agents that ground answers in your linked pages cite your site more accurately, which drives traffic.
Run a scan against your domain to see whether llms_txt.present currently passes, warns, or fails. Free, no signup; the score page is permanent and citable.
