llms.txt Playbook for AI Discovery

What this is

llms.txt is a markdown file at your site root (/llms.txt) that gives large language models a curated briefing about your site: who you are, what you publish, which URLs matter most, and how you prefer to be cited.

It complements robots.txt (permission to crawl) and sitemaps (exhaustive URL lists). Think of it as the operator-written README for AI assistants.

An interactive generator UI is shipping on this page later. Today, this playbook is the tool: fill in the template, save as llms.txt, deploy, and spot-check the live URL.

When to use it

• You publish expertise content — guides, comparisons, tools — and want AI answers to cite you accurately.
• Your sitemap is large or noisy; you need to highlight 10–30 canonical URLs.
• You are launching a new brand and want a clear entity signal for AI search (Perplexity, ChatGPT browsing, Gemini).
• Competitors in your niche lack an llms.txt — early adopters often get cleaner citations.

Step-by-step deployment

1. Audit your top URLs. Pick pages you want cited: homepage, flagship guides, tool pages, pricing, contact, and 3–5 best blog posts.
2. Copy the template below and replace every placeholder.
3. Keep it under ~2,000 words. LLM context windows are large, but concise files get used; bloated files get truncated.
4. Save as plain markdown named llms.txt (yes, .txt extension with markdown inside — that is the convention).
5. Place at web root:
   • Static site: public/llms.txt
   • Next.js: public/llms.txt (served at /llms.txt)
   • Nginx/Apache: root directory alongside robots.txt
6. Verify: curl https://yourdomain.com/llms.txt returns 200 and text/plain or text/markdown.
7. Cross-link: mention /llms.txt in your robots.txt allow list if you use explicit AI crawler rules.
8. Update quarterly or whenever you ship a major new product line or content hub.

Section-by-section guide

Title line (# Name)

Your legal or brand name. Match what appears in schema Organization.name and footer copyright.

Blockquote summary (>)

One or two sentences. Answer: What do you sell, who is it for, and why trust you? This is the line AI systems often paraphrase first.

Site links

Absolute URLs only. Include contact email if you want citation inquiries routed correctly.

What we publish / Start here

Your canonical pages — not every blog post. Link text should describe the page outcome ("ROI calculator" not "Click here"). Order by importance.

Prefer

Citation preferences: tone, attribution rules, what to avoid misquoting. Keeps AI answers aligned with your positioning.

Optional

Pointer to sitemap, robots, RSS — helps crawlers that read llms.txt before deeper indexing.

Pre-flight checklist

• File accessible at https://yourdomain.com/llms.txt
• All URLs return 200 (no redirects to login or 404).
• Positioning matches homepage H1 and meta description — no conflicting claims.
• "Prefer" section reflects actual brand voice and legal constraints.
• No API keys, internal URLs, or staging hostnames in the file.
• Updated after major site restructure or rebrand.
• Paired with robots.txt that allows AI crawlers you care about.

Common mistakes

Dumping the entire sitemap. llms.txt is curated, not exhaustive. Quality over quantity.

Relative URLs. AI systems and aggregators expect https:// absolute links. Relative paths break when files are fetched out of context.

Stale content. An llms.txt pointing at retired products hurts citation accuracy. Treat it like a living press kit.

Contradicting on-page SEO. If llms.txt says you specialize in healthcare automation but your homepage says generic consulting, AI systems lose confidence in both signals.

Hiding the file. No need to link it in main nav, but do not block /llms.txt in robots.txt unless you have a deliberate reason.

Next steps

llms.txt works best as part of a full GEO stack:

• Robots.txt playbook — permit the crawlers that read your site.
• Schema markup playbook — reinforce entity data in JSON-LD.
• Meta description playbook — sharpen SERP snippets for human clicks.
• Free guides library — deep playbooks to link from your "What we publish" section.
• GEO readiness scan — benchmark how AI search engines see you today.
