Search is changing. AI assistants are now answering questions that used to go straight to Google. A single small file on your website could be the difference between your business getting recommended or ignored entirely.

Imagine a customer asks their phone's AI assistant: "What's the best Italian restaurant near me that does private dining?" Instead of showing a list of blue links, the AI just answers — and either recommends your restaurant, or it doesn't.

That's the world we're already living in. And unlike traditional Google SEO, where you can spend months climbing the rankings, there's a simpler, more direct way to help AI tools understand and recommend your business: a file called llms.txt.

What is llms.txt, in plain English?

Think of it like a cheat sheet you leave out for the AI. When a customer asks an AI assistant something — "Does this plumber cover my area?", "What are this salon's hours?", "Can this restaurant cater for my event?" — The AI has to quickly figure out what your business is about. Most websites weren't built to be read that way, and a lot of important information gets lost in the noise.

An llms.txt file lives on your website (at yourwebsite.com/llms.txt) and gives AI assistants a clear, organized summary of who you are, what you do, and where to find more details. It's a bit like a welcome letter, written for machines instead of people.

The bottom line: An llms.txt file tells AI assistants exactly what your business does, in a format they can actually understand — so they can recommend you with confidence.

Why should a local business care?

You've probably already heard of SEO — optimizing your website so it shows up on Google. llms.txt is the next evolution of that idea. AI search tools like ChatGPT, Google's AI Overviews, and voice assistants are increasingly being used to find local services, make recommendations, and answer questions. If these tools can't clearly understand your business, they'll either get it wrong or skip you entirely.

Here's what that looks like in practice:

  • A customer asks an AI for florists in their city that do same-day delivery — your florist shop offers it, but the AI doesn't know because the information is buried in your website's code.

  • Someone wants to know if your gym has a pool. The AI visits your site, gets confused by the design, and says it can't find that information.

  • A person asks for recommendations for a local accountant who handles small businesses. Your website mentions it — but not clearly enough for an AI to be sure.

An llms.txt file fixes all of this by putting the right information front and center, in a format AI tools are designed to read.

"It's like having a knowledgeable member of staff on call 24/7, briefing every AI assistant that asks about your business."

What does one actually look like?

Here's a simple, real-world example for a fictional plumbing business. Don't worry about the technical formatting — a web developer or even a basic text editor can create this in minutes:

# Murphy's Plumbing Services

> Family-run plumbing company serving Dublin and surrounding counties since 1998. Emergency call-outs available 24/7. Fully licensed and insured.

We specialize in boiler servicing, bathroom installations, leak repairs, and drain unblocking. Free quotes provided. Senior citizen discounts available.

That's it. A few clear lines of text, and suddenly every AI assistant that encounters your website knows who you are, what you do, where you work, and where to find more information.

How to get one set up

Good news: you don't need to be technical to make this happen. Here's the basic process:

  1. Write a plain-English summary of your business. What do you do? Who do you serve? What makes you different? What are your key services or products? Jot it down in a few sentences — this becomes the heart of your file.

  2. List the most important pages on your website. Think about your services page, your contact/location page, your FAQ, and your about us section. These are the links you'll include so AI tools can dig deeper.

  3. Have a developer or web person create the file. Show them this article — the format is simple and standardized. It should take under an hour to set up. If you use a website platform like WordPress, there are plugins that can help automate this.

  4. Keep it updated. Changed your hours? Added a new service? Moved location? Update the file. Think of it like keeping your Google Business Profile current — it's worth maintaining.

Is this really worth it for a small business?

Absolutely — and arguably more so for small businesses than large ones. Big brands have entire teams working on their digital presence. Local businesses rarely do. An llms.txt file is one of the few things you can do right now, at almost zero cost, that gives AI tools a clear picture of who you are.

The businesses that figure this out early will have a head start as AI search becomes the default for more and more customers. We're still in the early days — which means there's an opportunity right now to stand out before everyone else catches on.

Quick checklist: Make sure your llms.txt includes: your business name and a one-sentence description · your key services or products · your location and service area · your opening hours · links to important pages (services, contact, FAQ) · anything that makes you different from competitors

The bottom line

AI assistants are becoming the new search bar — and they need clear, honest information to recommend the right businesses to the right customers. An llms.txt file is your direct line to that conversation. It's small, it's free to create, and it could make a real difference to how often your business gets found and recommended in the age of AI search.
