llms.txt is a proposed web standard: a plain-text markdown file served at yoursite.com/llms.txt that gives AI systems a clean, structured summary of who you are, what you do, and where your key pages live. For a local business it's an hour of work, and it makes you easier for answer engines to read correctly. It is not a magic ranking lever — and anyone selling it as one is selling smoke.
What llms.txt actually is
Websites are built for human eyes: navigation menus, hero animations, cookie banners. An AI system trying to understand your business has to dig through all of it. llms.txt — proposed as a standard at llmstxt.org — is the shortcut: one markdown file listing your business description, services, service area, and links to your most useful pages, in a format machines parse cleanly. Think robots.txt, but for meaning instead of crawling permissions.
How much does it matter for a local business?
Honestly: it's a foundation brick, not a growth loop. Adoption by AI systems is real but uneven, and no file makes ChatGPT recommend a plumber with three reviews. What it does is remove ambiguity — your services, your service area, your hours, stated plainly at a predictable address — so when an answer engine does read you, it gets the facts right. The heavyweight visibility levers remain what they've always been: a complete Google Business Profile, a steady stream of genuine reviews, and content that answers real buyer questions.
How AI search decides which businesses to mention
What goes in a local business's llms.txt
- ›One-paragraph plain-language description: who you serve, what you do, where.
- ›Services list with a line each — the words customers use, not internal jargon.
- ›Service area, hours (including emergency availability), and how to book.
- ›Links to your most load-bearing pages: services, reviews/testimonials, FAQ, contact.
- ›Anything an AI answering 'who should I call for X in Y?' would need to represent you accurately.
“It's an hour of work to make sure the machines quoting your business get the facts right. Do it, then get back to answering your phone — that's still where the money is.”
We run one ourselves
This site ships its own llms.txt — every service, article, and skill listed in machine-readable form, updated automatically as content changes. Practice what you preach: it's part of the same AI Visibility loop we install for operators, sequenced after lead capture and follow-up are solid.
