If you've heard about LLMS.txt files but aren't sure what they are or why they matter, you're in the right place. This guide will explain everything you need to know—and show you how to create one for your business in about 15 minutes.

What Is an LLMS.txt File?

An LLMS.txt file is a simple text document you add to your website that helps AI assistants (like ChatGPT, Claude, and Gemini) quickly understand your business.

Think of it like a resume for AI—a structured summary of who you are, what you do, where you're located, and why you're trustworthy.

The file lives at yourwebsite.com/llms.txt and can be read by anyone (or any AI) that visits that URL.

Why Does It Matter?

When AI assistants crawl your website to learn about your business, they encounter a lot of noise:

• Navigation menus
• Cookie consent banners
• Footer links
• Sidebar widgets
• Ads and promotional content

All of this "noise" makes it harder for AI to extract the essential information about your business. An LLMS.txt file cuts through the clutter by providing a clean, structured overview that AI can easily digest.

What to Include in Your LLMS.txt

A good LLMS.txt file should cover these essential sections:

1. Business Name and Tagline

Start with your business name and a one-sentence description of what you do.

# Acme Plumbing & Heating

> Denver's trusted plumbing and HVAC company since 1995, serving residential and commercial customers throughout the Front Range.

2. About Section

A 2-3 paragraph overview of your business. Include:

• What you do
• Who you serve
• What makes you different
• Your experience and credentials

3. Services

List your main services with brief descriptions. Be specific—"Emergency water heater repair" is better than "Plumbing services."

4. Location & Service Area

Clearly state where you're located and which areas you serve. Include:

• Physical address
• Neighborhoods or cities you cover
• Any licensing information for specific regions

5. Specializations

What are you known for? What's your niche? List 3-5 things that set you apart.

6. Contact Information

Phone, email, website, and physical address. Make it easy for AI to direct customers to you.

7. Social Proof

Years in business, number of customers served, certifications, awards, and professional memberships.
