If you've heard about LLMS.txt files but aren't sure what they are or whether they're worth your time, this guide walks through it. Short version: it's a minor, optional tactic, and it only applies to some websites. Here's the honest picture and how to set one up if it fits.
- The major AI search engines don't currently fetch llms.txt. There's no evidence ChatGPT, Claude, Gemini, or Perplexity read it when answering questions. Treat it as a small bet, not a growth lever.
- If you're on Shopify, you don't create this file — Shopify does it for you. Shopify auto-serves
/llms.txt(and/agents.md) for every store. See the Shopify section below.
The rest of this guide is aimed at self-hosted and non-Shopify websites (WordPress, custom sites, traditional hosting), where publishing the file is at least in your control. Your reviews, your website content, and your presence on the sites AI actually reads matter far more than this file.
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.
Real-World Benefits
- A clean summary in one place: if an AI tool does read it, it gets your business described the way you'd describe it, without the clutter
- Consistency: a single source of truth for your name, services, and location that you can point other tools at
- Low cost: it's quick to make and does no harm, so it's a reasonable thing to have in place in case adoption grows
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.

How to Create Your LLMS.txt File
Option 1: Use BrandIndex AI (Easiest)
If you're a BrandIndex AI user, our LLMS.txt generator creates the file automatically based on your business information. It takes about 2 minutes:
- Log in to BrandIndex AI
- Navigate to "LLMS.txt Generator"
- Review and customize the generated content
- Download the file
- Upload to your website
Option 2: Create It Manually
- Open a text editor (Notepad, TextEdit, or any code editor)
- Copy the template from this guide
- Fill in your information following the examples above
- Save the file as
llms.txt(plain text, no special formatting) - Upload to your website root so it's accessible at
yourwebsite.com/llms.txt
How to Upload Your LLMS.txt File
WordPress
- Install the "File Manager" plugin or use your hosting file manager
- Navigate to the root directory of your site (where
wp-config.phpis located) - Upload
llms.txtto this directory - Verify by visiting
yoursite.com/llms.txt
Squarespace
- Go to Settings > Advanced > Code Injection
- Unfortunately, Squarespace doesn't support root-level file uploads
- Workaround: Create a page at
/llms-txtand paste your content there
Wix
- Similar limitation to Squarespace
- Create a new page and format the content as plain text
Shopify (you don't need to do this)
Shopify now serves /llms.txt, /llms-full.txt, and /agents.md automatically for every store, generated from your store and catalog data. You don't create or upload a file. If you want to customize what's served, you do it by editing the matching theme template (for example agents.md.liquid), not by dropping a file in a root folder. For most merchants the automatic version is fine, and your effort is better spent on your product descriptions and the Knowledge Base, which is what AI shopping agents actually read.
Custom Website / Traditional Hosting
- FTP or SSH into your server
- Upload
llms.txtto your public_html or www root directory - Verify file permissions (should be 644)
Best Practices
Do:
- Update regularly: Review quarterly and update when services change
- Be specific: "Emergency plumbing repair" beats "Plumbing services"
- Include your location: AI needs to know where you serve
- Add credentials: Licenses, certifications, and professional memberships build trust
- Keep it accurate: Outdated information hurts more than no information
Don't:
- Stuff keywords: Write naturally, not "Denver plumber Denver CO best plumber Denver"
- Make false claims: AI cross-references information—inconsistencies hurt credibility
- Forget to update: An outdated LLMS.txt with old hours or discontinued services is worse than none
- Use marketing fluff: "World-class service" means nothing. Specifics matter.
Testing Your LLMS.txt
After uploading, verify everything is working:
-
Direct access: Visit
yourwebsite.com/llms.txtin your browser. You should see your plain text content. -
AI testing: Ask ChatGPT, Claude, or Gemini about your business and see if the information matches your LLMS.txt content.
-
BrandIndex AI: Use our platform to test your visibility across multiple AI platforms and see if your LLMS.txt is being picked up.
Common Questions
Q: Is LLMS.txt an official standard? A: No. It's a community proposal, not something the major AI companies have adopted. As of late 2026, the big AI search engines don't appear to fetch it when answering questions, so don't expect visibility gains from the file alone. The one place it's genuinely baked in is Shopify, which auto-generates it for stores. On a self-hosted site it costs little and does no harm to have, so it's fine as a low-priority item — just don't treat it as the thing that gets you recommended.
Q: How often should I update my LLMS.txt? A: Review quarterly at minimum. Update immediately when you add services, change locations, earn new credentials, or update contact information.
Q: Will this replace SEO? A: No—LLMS.txt complements your SEO efforts. You still need a well-optimized website, but LLMS.txt helps AI assistants specifically understand your business.
Q: Does LLMS.txt help with Google search rankings? A: LLMS.txt is designed for AI assistants, not traditional search engines. For Google rankings, focus on traditional SEO best practices.
Get Started Now
If you run a self-hosted site, an LLMS.txt file takes about 15 minutes and does no harm, so it's a reasonable box to tick. Just keep it in perspective: it's a minor, optional tactic, not the lever that gets you recommended. The real work is strong reviews, clear website content, and showing up on the sites AI actually reads.
