Why it matters

llms.txt is a single Markdown file at /llms.txt that gives LLMs a curated, token-efficient map of a site's most important documentation, bypassing the noise of full HTML pages. AI engines and the agents feeding them ingest it deterministically, raising the chance your canonical content is the version they cite.

Geordy generates this format for every page on your site that warrants it - auto-detected by page type, served from your subdomain, and refreshed on the cadence below.

Get it right

How to make this format work for AI.

DoBest practices
  • Place the file at the root: https://yourdomain.com/llms.txt (and optionally an expanded /llms-full.txt with inlined content).
  • Open with an H1 (site name), then a blockquote one-line summary, then short prose context, then H2 sections of links - strict spec order.
  • Each link should be `[Title](url): short description` and point to clean Markdown versions of pages where possible (e.g. /docs/foo.md).
  • Curate, don't dump. Use an Optional H2 section for material that can be skipped under tight context.
AvoidCommon pitfalls
  • Treating it like a sitemap.xml dump - listing every URL defeats the curation purpose and wastes the model's context.
  • Linking to JS-heavy HTML pages instead of plain Markdown/text equivalents the LLM can actually parse cheaply.
  • Skipping the required structure (H1 + blockquote + H2 link sections); ad-hoc Markdown breaks tools that parse the spec strictly.
