What is llms.txt and does my local business website need one?
TL;DR: llms.txt is a proposed standard (Jeremy Howard, September 2024): a markdown file at yoursite.com/llms.txt that gives AI systems a clean, curated summary of your site — who you are, what you offer, and links to your key pages. Adoption by engines is still uneven in 2026, but it costs 20 minutes, can't hurt, and pairs with schema as your machine-readable front door.
The short answer, backed up
Think of llms.txt as the AI-era sitemap: not a ranking lever by itself, but a cheap way to make sure any assistant that does read it gets your business facts right — services, areas, hours, booking link — instead of reconstructing them from scattered pages.
Evidence:
- The llms.txt proposal was published by Jeremy Howard (Answer.AI) in September 2024 and adopted through 2025 by thousands of sites, including major docs platforms (Anthropic's docs among early adopters).
- Directory sites like llmstxt.site tracked adoption growing through 2025; support among crawlers remains partial — which is why it complements, not replaces, schema and listings.
- Google's John Mueller (2025) noted no confirmed ranking use by Google — set expectations accordingly; the value is accuracy for agents that read it, not rank.
- LocalBusiness JSON-LD remains the confirmed machine-readable channel all engines parse; llms.txt is the low-cost supplement.
llms.txt vs. the rest of your machine-readable stack
| Asset | Read by | Confirmed value | Effort |
|---|---|---|---|
| LocalBusiness + FAQPage schema | All major engines | High — parsed and cited | 1-2 hours |
| robots.txt AI-crawler allows | All AI crawlers | High — gatekeeper | 10 minutes |
| llms.txt | Some AI tools/agents (partial 2026 adoption) | Speculative-to-modest | 20 minutes |
| Sitemap.xml | All crawlers | High — discovery | Usually automatic |
Step-by-step
- Create a plain markdown file: one H1 (business name), a one-paragraph summary, then sections linking your services, areas, pricing, FAQ, and booking pages.
- Include hard facts agents need: service area, hours, phone, booking URL.
- Upload to your web root as /llms.txt and reference key pages by absolute URL.
- Keep it in sync when services or hours change — a stale llms.txt is worse than none.
- Prioritize it after schema, listings, and crawler access — those carry confirmed weight.
FAQ
Will llms.txt make ChatGPT recommend me?
Not by itself. It improves accuracy for systems that read it; recommendations still come from listings, reviews, and citations.
Is it the same as robots.txt?
No — robots.txt controls access; llms.txt offers curated content. They complement each other.
What goes in it for a salon or HVAC company?
Business name, one-paragraph description, services with links, service area, hours, phone, booking link, and your FAQ page.
Does BookRails generate it?
Yes — the GEO Action Center generates llms.txt and schema from your business profile so the whole machine-readable layer stays consistent.
