How to Add llms.txt to Your Small Business Website

If you’ve heard the term “llms.txt” floating around lately and wondered whether your small business actually needs one, the short answer is yes. The longer answer is that it takes about thirty minutes to write a good one, costs nothing to publish, and is one of the highest-leverage things you can do this year to make your website visible to AI assistants.

Here’s what it is, why it matters, and exactly how to add one.

What llms.txt Actually Is

llms.txt is a plain-text file that lives at the root of your website — same spot as robots.txt and sitemap.xml. Its job is simple: tell AI assistants what your business does, what you offer, and where to find more detail.

Think of it as a hand-written briefing document for ChatGPT, Claude, Perplexity, and Google’s AI Overviews. When one of those tools is about to answer a question that involves your business, it reads llms.txt first to get its bearings.

The format was proposed in late 2024 and has quickly become a de facto standard. Most websites still don’t have one. The ones that do tend to get cited more often when AI assistants answer questions in their category.

Why AI Assistants Use It

LLMs have a problem when they crawl ordinary HTML. A typical small business homepage is full of navigation, footers, hero images, marketing fluff, and dynamically rendered content. Extracting clean facts from that mess is hard, and the model often gets it wrong — wrong hours, wrong services, wrong pricing, sometimes the wrong business entirely.

llms.txt solves that. It’s a clean, structured, human-written summary of what matters. No ambiguity. No marketing fluff. Just facts the AI can lift directly into an answer.

The result is fewer hallucinations about your business and more accurate citations. That’s good for you and good for the AI — which is why the bigger platforms have started actively reading the file.

What to Put in It

The format is loose by design — the spec is closer to “a markdown summary the AI can scan” than a rigid schema. That said, there’s a pattern that works well for small businesses:

A one-line tagline. Who you are and what you do.
Business basics. Name, location, service area, contact, hours.
What you offer. Services or products with prices where possible.
Key facts. Differentiators, certifications, years in business, team size.
A list of important pages. Pricing, services, about, contact, key blog posts.
An FAQ section. Common questions a customer would actually ask an AI.

Front-load the most important information. AI assistants often only read the first chunk of the file before forming an answer.

Where to Put It

The file goes at the absolute root of your domain. If your site is https://yourbusiness.ca, the file lives at https://yourbusiness.ca/llms.txt.

Not in a subfolder. Not under /docs/ or /about/. The root.

How you put it there depends on your platform:

WordPress. Use a plugin like “All-in-One SEO” or upload the file via FTP to your public_html directory.
Squarespace, Wix, Webflow. Look for a “Custom Files” or “Code Injection” setting. Some platforms still require a workaround — check your platform’s documentation for “static file at root” or contact support.
Static sites (Astro, Next.js, Hugo, etc.). Drop the file in your public/ or static/ directory. It will be served at root automatically.
Shopify. Add via the theme files in the admin, under Online Store > Themes > Edit code, in the templates folder as a custom page redirected to /llms.txt.

How to Test It

Once the file is published, two quick tests will tell you it’s working:

Test 1: Direct fetch. Open https://yourbusiness.ca/llms.txt in a browser. The file should load as plain text, not 404. If it doesn’t, your platform isn’t serving the file at root — fix the path or deployment.

Test 2: Ask an AI. Open ChatGPT (with web search on), Claude, or Perplexity. Ask “What does [your business name] do?” If the answer reflects facts from your llms.txt — accurate hours, accurate prices, accurate service area — the file is being read.

It can take a few days to a few weeks for the first crawl. Be patient, and re-test in a couple of weeks.

A Few Things to Avoid

Don’t auto-generate from your sitemap. Tools that just dump every page title produce a mediocre llms.txt. Hand-write the important parts.
Don’t include marketing fluff. “Industry-leading,” “innovative,” “passionate” — strip all of it. Stick to facts.
Don’t omit pricing. If you have prices, publish them. AI assistants strongly prefer concrete numbers and will cite businesses that provide them over those that don’t.
Don’t forget to update it. When prices change, hours change, or you add a service, update the file. Stale llms.txt produces stale citations.

Why This Matters for Small Businesses

Most large businesses have entire content teams optimizing for AI search. Most small businesses don’t even know it exists. That gap is the opportunity.

A well-written llms.txt is one of the few things you can do once that gives you a durable advantage in answer engine optimization. The cost is thirty minutes of writing. The payoff is showing up by name when potential customers ask ChatGPT or Claude for a recommendation in your category.
