Best llms.txt Examples 2026

Last updated: April 2026

llms.txt is a plain text file you add to your website root (yourdomain.com/llms.txt) that tells AI platforms what your business does, what you offer, and what your key content is. Think of it as a cover letter for AI. It is not a standard yet, but ChatGPT and Perplexity both read it when available. Adding one takes 15 minutes and costs nothing.

Below you will find a full breakdown of what to include, three complete examples you can copy and adapt, and section-by-section guidance on writing each part well.

Section-by-section guidance

Each of the eight sections in your llms.txt file serves a specific purpose. Here is what to write, what works well, and what to avoid.

1. Business name and description

Start with your business name as a heading, then write one clear sentence explaining what your business does. Be specific. AI platforms use this as the anchor for everything else in the file.

Good example: "Reynolds Plumbing is a Gas Safe registered plumbing and heating company serving homes and businesses across Bristol."

Bad example: "We are a dynamic, forward-thinking solutions provider committed to excellence in the built environment space."

2. Core services or products

List your main services or products as a simple bulleted list. Use plain language. Write what a customer would search for, not internal jargon.

Good example: "Boiler installation and servicing, emergency plumbing repairs, bathroom fitting"

Bad example: "End-to-end thermal management solutions, integrated wet-room experiences"

3. Key facts and differentiators

Include specific, verifiable facts that set you apart. Numbers, certifications, and track records are far more useful to AI than vague claims. This is where you prove credibility.

Good example: "Gas Safe registered. 14 years in business. 4.9 stars from 187 Google reviews."

Bad example: "We pride ourselves on delivering exceptional customer service every time."

4. Target audience

Tell AI exactly who you serve. Be specific about the type of customer, their size, their industry, or their location. This helps AI match your business to the right queries.

Good example: "Homeowners and landlords in Bristol who need reliable plumbing and heating work."

Bad example: "Anyone who needs our services."

5. Location and coverage

State where you are based and where you operate. Include the town, city, region, and coverage radius. For online businesses, state whether you serve the UK, EU, or internationally.

Good example: "Based in Bedminster, Bristol BS3. Covers Bristol, Bath, Keynsham, and surrounding areas within 20 miles."

Bad example: "We're based in the South West."

6. Contact information

Include phone, email, website URL, and any booking links. AI platforms may surface this directly in answers, so make sure it is accurate and up to date.

Good example: "Phone: 0117 496 0012. Email: [email protected]. Book online: reynoldsplumbing.co.uk/book"

Bad example: "Get in touch via our website."

7. Key content links

Link to your 3 to 5 most important pages. These should be your best guides, your most valuable resources, or the pages that best represent your expertise. AI platforms use these to find content worth citing. At Rank4AI, our own llms.txt links to our top research pages and the AI visibility audit.

Good example: "Guide: /guides/r-and-d-tax-credits-explained. Blog: /blog/spring-budget-2026-what-it-means-for-small-businesses"

Bad example: A list of 40 links with no labels or context.

8. Credentials and trust signals

Include professional registrations, certifications, awards, and media mentions. These are the signals AI uses to decide whether your business is credible enough to recommend.

Good example: "B Corp certified (score: 94.2). Featured in The Guardian and Vogue UK. Winner: Drapers Sustainable Fashion Awards 2025."

Bad example: "We've won loads of awards over the years."

Frequently asked questions

Is llms.txt an official standard?

Not yet. It is an emerging convention. There is no formal specification, but the format is simple enough that consistency has emerged naturally. AI platforms that support it read a plain text file at /llms.txt.

Which AI platforms read llms.txt?

ChatGPT and Perplexity are the most likely to read it. Gemini may reference it indirectly through Google's crawling. It is low-effort enough that adding one is worthwhile regardless.

How long should llms.txt be?

Keep it under 500 words. It is a summary, not your entire website. Include the essentials: who you are, what you do, who you serve, and where to find your best content.

Can llms.txt hurt my visibility?

No. It is purely additive. AI platforms that do not support it simply ignore the file. There is no downside.

Should I also have an ai-sitemap.txt?

It helps. An ai-sitemap.txt lists your most important pages in a format AI can quickly scan. Combined with llms.txt, it gives AI a complete picture of your business and content.
