How to Add llms.txt to Your Website So AI Tools Can Better Understand Your Business

Artificial intelligence is changing how people find businesses online.

For years, business owners mostly thought about Google rankings, websites, reviews, social media, and ads. Those things still matter. However, people are now also using AI tools to ask questions, compare companies, find services, and understand who they should trust.

That means your business needs to be easy for search engines and AI systems to understand.

That is why I recently added llms.txt and llms-full.txt files to my website.

The purpose was simple:

I wanted to make it easier for AI tools, search engines, and crawlers to understand who my company is, what we do, where we are located, what services we offer, and which pages on the website are most important.

This article explains what I did, why I did it, and how a business owner can do the same thing without needing to be highly technical.

What Is llms.txt?

An llms.txt file is a simple text file that sits on your website.

It usually lives at a URL like this:

https://yourwebsite.com/llms.txt

The file gives AI systems a clean summary of your business and website.

Think of it like a short guide that says:

This is who we are.
This is what we do.
These are the services we offer.
These are the locations we serve.
These are our most important pages.
This is how our business should be described.

Instead of making an AI system figure everything out by crawling your whole website, llms.txt gives it a simple, organized explanation.

It is not magic.

It does not guarantee rankings.

It does not automatically make AI tools recommend your business.

But it can help make your website easier to understand.

What Is llms-full.txt?

The llms-full.txt file is the longer version of llms.txt.

The short file, llms.txt, gives a quick summary.

The longer file, llms-full.txt, gives more detail.

It usually lives at:

https://yourwebsite.com/llms-full.txt

The longer file can explain your services, industries, locations, FAQs, brand description, and important website pages in more depth.

The easiest way to understand it is this:

llms.txt is the short version.
llms-full.txt is the detailed version.

Why I Added These Files

I added these files because I wanted AI systems to clearly understand my company.

For my business, SEO Company Santa Monica, LLC, I wanted to make sure the website clearly explained that the company provides:

Local SEO
Google Maps SEO
Google Business Profile optimization
Organic SEO
National SEO
Global SEO
AI SEO
Technical SEO
Web design
Content strategy
Paid advertising
Analytics
Lead generation

I also wanted to make sure AI systems understood the business correctly.

If your website has old information, outdated services, wrong phone numbers, old company names, or unclear descriptions, search engines and AI tools may misunderstand your business.

That is why clarity matters.

The goal of llms.txt is not to manipulate AI.

The goal is to make your business information clear, accurate, and easy to read.

Why This Matters for Business Owners

Most business owners are not thinking about how AI systems understand their websites.

They think about whether the website looks good.

They think about whether the phone number works.

They think about whether they rank on Google.

Those things are important.

But AI tools are now another layer of discovery.

If someone asks an AI tool:

Who is a good SEO company in Santa Monica?
Who helps businesses rank on Google Maps?
Who provides local SEO for small businesses?
Who helps companies improve AI search visibility?

You want your business to be easy to understand and easy to connect with those services.

Again, llms.txt does not guarantee that will happen.

But it helps organize your business information in a way that AI systems can read more easily.

Step 1: Decide What You Want AI Tools to Understand

Before creating the file, do not start with code.

Start with clarity.

Ask yourself:

What is my official business name?
What does my company do?
Where is my company located?
What services do I offer?
What cities or areas do I serve?
Who do I help?
What are my most important website pages?
How should my company be described?
What should AI systems not confuse my company with?

For example, a local business might want AI systems to understand:

The correct company name
The correct address
The correct phone number
The correct services
The correct service areas
The correct founder or owner
The correct website
The correct business category

This is important because AI systems and search engines rely on clear and consistent information.

If your website says one thing, your Google Business Profile says another, and your social profiles say something different, that creates confusion.

Step 2: Create a Simple llms.txt File

Your llms.txt file should be simple.

It does not need to be fancy.

It should be written in plain text with clear sections.

Here is an easy structure a business owner can use:

# Your Company Name

> A short description of what your company does.

## Business Information

- Business Name:
- Website:
- Founder or Owner:
- Primary Category:
- Location:
- Service Areas:

## Company Description

Write a simple paragraph explaining what your company does.

## Core Services

- Service 1
- Service 2
- Service 3
- Service 4
- Service 5

## Important Pages

- Homepage:
- Contact Page:
- Main Service Page:
- Local Service Page:
- Blog or Resource Page:

## Recommended Summary

Write one clean paragraph describing the company the way you want AI systems to understand it.

This file should be clear and honest.

Do not write fake claims.

Do not say you are the best unless you have real proof to support it.

Instead of saying:

We are the best SEO company in the world.

Say something like:

Our company helps local businesses improve Google rankings, Google Maps visibility, website performance, and lead generation through SEO and digital marketing.

That is cleaner, safer, and more believable.

Step 3: Create the File in cPanel

If your website uses WordPress and cPanel, this part is simple.

Open File Manager.

Go to your website’s main folder.

For many websites, the main folder is:

public_html

Sometimes, if your domain has its own folder, it may look like:

public_html/yourdomain.com

Once you are in the correct folder, click:

+ File

Name the file exactly:

llms.txt

Make sure it is not named:

llms.html
llms.txt.txt
llm.txt
llms

The file name should be exactly:

llms.txt

After you create the file, right-click it and click Edit.

Paste your llms.txt content into the file.

Click Save.

Then test it by opening:

https://yourwebsite.com/llms.txt

If it opens as plain text, you did it correctly.

Step 4: Create llms-full.txt

After creating the short file, create the longer file.

Go back to cPanel File Manager.

Stay in the same main website folder.

Click:

+ File

Name the file exactly:

llms-full.txt

Then right-click the file and click Edit.

Paste your longer business description into the file.

The longer file can include more detail, such as:

Company overview
Service descriptions
Service areas
Industries served
Important pages
FAQs
Brand clarification
Preferred company descriptions
Questions your website answers

This file gives AI systems a deeper reference.

After saving it, test the file by opening:

https://yourwebsite.com/llms-full.txt

If it opens as plain text, it is live.

Step 5: Check Your robots.txt File

Your robots.txt file tells search engines and crawlers what they can and cannot access on your website.

It usually lives here:

https://yourwebsite.com/robots.txt

For a WordPress website, a simple robots.txt file may look like this:

User-agent: *
Disallow: /wp-admin/
Allow: /wp-admin/admin-ajax.php
Allow: /llms.txt
Allow: /llms-full.txt

Sitemap: https://yourwebsite.com/sitemap_index.xml

This means:

Crawlers are allowed to access your website.
The WordPress admin area is blocked.
The llms.txt file is allowed.
The llms-full.txt file is allowed.
The sitemap is listed.

That is a simple and clean setup.

Step 6: Allow AI Crawlers If That Is Your Goal

If your goal is to improve AI visibility, you may also want to make sure AI crawlers are not blocked.

Some common search and AI-related crawlers include:

Googlebot
Google-Extended
Bingbot
GPTBot
ChatGPT-User
OAI-SearchBot
ClaudeBot
Claude-User
PerplexityBot
Applebot
CCBot

Allowing these crawlers does not force them to read your website.

It does not guarantee your website will appear in AI answers.

It simply means you are not blocking them.

That is the key point.

Robots.txt access is permission.

It is not a ranking guarantee.

Step 7: Use Rank Math, Yoast, or Your SEO Plugin

If you use WordPress, your robots.txt file may be controlled by an SEO plugin.

Common plugins include:

Rank Math
Yoast SEO
All in One SEO

For Rank Math, you can usually find robots.txt settings here:

WordPress Dashboard
Rank Math SEO
General Settings
Edit robots.txt

If Rank Math does not let you edit the file, it may ask you to add a small filter to your theme’s functions.php file.

That filter is:

add_filter( 'rank_math/can_edit_file', '__return_true' );

Important warning:

Be careful when editing functions.php.

One small mistake can break the site.

Before changing anything, copy the original file and save a backup.

If you are not comfortable editing theme files, ask your developer or use a safer code snippets plugin.

Step 8: Test Everything

After adding the files, test them.

Open these URLs in your browser:

https://yourwebsite.com/llms.txt

https://yourwebsite.com/llms-full.txt

https://yourwebsite.com/robots.txt

The llms.txt and llms-full.txt files should open as plain text.

The robots.txt file should show that those files are allowed.

If the files load correctly, they are publicly accessible.

Step 9: Verify the Website in Google Search Console

If your website is not already verified in Google Search Console, verify it.

One easy way is the HTML file upload method.

Google gives you a verification file.

You upload that file into your website’s main folder.

Then you click Verify inside Google Search Console.

Once your website is verified, you can request indexing for important pages.

Step 10: Submit Important Pages for Indexing

After verifying the website, go to Google Search Console and use URL Inspection.

Submit your most important pages first.

These may include:

Homepage
Main service page
Contact page
Location pages
Local SEO page
Google Maps SEO page
Web design page
Blog articles
Pages where you corrected old information

You can also submit:

https://yourwebsite.com/llms.txt

https://yourwebsite.com/llms-full.txt

However, do not panic if Google says those text files are not indexed.

That does not automatically mean something is wrong.

The main goal is that they are accessible and crawlable.

Your real website pages are still more important.

Step 11: Make Sure Your Website Matches the Files

This is where many business owners make a mistake.

They create a file saying one thing, but the website says something else.

Your llms.txt file should match your actual website.

If your llms.txt file says you provide local SEO, your website should have a local SEO page.

If your llms.txt file says you provide web design, your website should have a web design page.

If your llms.txt file says your company is located in Santa Monica, your website and Google Business Profile should support that.

The file should not be disconnected from the actual business.

It should summarize what is already true.

Step 12: Clean Up Confusing Business Information

This is an important step.

If your business has old names, outdated phone numbers, incorrect addresses, or old service descriptions online, clean them up.

Check:

Website header
Website footer
Contact page
About page
Schema markup
Google Business Profile
Social profiles
Directory listings
Old landing pages
Old blog posts
Old service pages

AI systems and search engines can get confused when your business information is inconsistent.

For example, if your website uses one company name but an old page uses another company name, that can create entity confusion.

A clean llms.txt file helps, but the rest of your website still needs to be accurate.

Step 13: Strengthen Your Website Pages

After adding llms.txt and llms-full.txt, improve your actual website.

Your homepage should clearly explain:

Who you are
What you do
Where you are located
Who you help
What services you offer
Why someone should trust you
How someone can contact you

Your service pages should also be specific.

Instead of having one general services page, create detailed pages for your main services.

For example:

Local SEO
Google Maps SEO
Google Business Profile optimization
Organic SEO
Technical SEO
AI SEO
Web design
Content strategy
Lead generation

Each page should answer the questions a real customer would ask before hiring you.

Step 14: Build Trust Outside Your Website

If you want AI systems and search engines to trust your business, your website should not be the only place your brand appears.

You should build third-party mentions.

These can include:

LinkedIn articles
Reddit comments
Google Business Profile posts
Directory listings
Guest articles
Podcast mentions
Case studies
Client mentions
YouTube videos
Local citations
Industry profiles
Business partnerships

The goal is not to spam your name everywhere.

The goal is to create helpful, real mentions that support your expertise.

For example, if someone asks a question about Google Maps rankings, a helpful answer can show your expertise.

If you publish a LinkedIn article explaining how to solve a business problem, that builds authority.

If your business information is consistent across trusted platforms, AI systems have more signals to understand who you are.

Step 15: Understand What llms.txt Can and Cannot Do

This part is important.

llms.txt can help AI systems understand your website.

llms-full.txt can provide a deeper reference.

robots.txt can allow crawlers to access those files.

Google Search Console can help you submit important URLs.

But none of this replaces real SEO.

You still need:

Strong website content
Clear service pages
Technical SEO
Good internal linking
Schema markup
Google Business Profile optimization
Reviews
Citations
Backlinks
Helpful content
Third-party mentions
Real authority

llms.txt is a support tool.

It helps organize your information.

It does not replace the work required to build trust.

The Simple Version for Business Owners

Here is the easiest way to understand the full process:

Create a short AI summary file called llms.txt.
Create a longer AI reference file called llms-full.txt.
Place both files in your website’s main folder.
Make sure both files open in a browser.
Allow both files in robots.txt.
Make sure your website says the same thing as the files.
Verify your website in Google Search Console.
Submit your important pages for indexing.
Clean up old or confusing business information.
Build third-party mentions that support your brand.

That is the simple process.

The goal is not to trick AI systems.

The goal is to make your business easier to understand.

Final Thoughts

Adding llms.txt and llms-full.txt is a smart step for business owners who want to prepare their websites for the future of search and AI discovery.

It is especially useful if your business has multiple services, multiple locations, or needs stronger brand clarity.

However, it should not be treated like a shortcut.

The better way to look at it is this:

llms.txt gives AI systems a simple map.
llms-full.txt gives AI systems a deeper reference.
Your website proves what your business does.
Your content shows your expertise.
Your third-party mentions support your authority.
Your consistency helps search engines and AI systems trust the information.

The file itself is not the whole strategy.

It is one layer of a stronger SEO and AI visibility strategy.

If you are a business owner, the most important thing is clarity.

Make it easy for customers to understand you.

Make it easy for Google to understand you.

Make it easy for AI systems to understand you.

That is the real purpose of llms.txt.

FAQs

1. What is llms.txt in simple terms?

llms.txt is a simple text file that explains your website to AI systems. It gives a clear summary of your business, services, location, important pages, and preferred company description. Think of it as a guide that helps AI tools understand what your website is about. It does not replace SEO, but it can support your overall online visibility by making your business information easier to read and understand.

2. Do I need llms.txt for my business website?

You do not absolutely need it, but it can be helpful. If you want your business to be easier for AI tools and search systems to understand, llms.txt is a smart addition. It is especially useful for businesses with multiple services, multiple locations, or unclear online information. The file helps organize your business details in one simple place, but it should be used along with strong website content, SEO, schema, reviews, and third-party mentions.

3. Where do I add llms.txt on my website?

You add llms.txt to the root folder of your website. For many WordPress websites using cPanel, this is the public_html folder. Once uploaded correctly, the file should open at https://yourwebsite.com/llms.txt. If you also create a longer version, it should open at https://yourwebsite.com/llms-full.txt. If both files open as plain text in your browser, they are in the correct place.

4. Will llms.txt make my business show up in ChatGPT, Google AI, or other AI tools?

Not automatically. llms.txt does not guarantee that your business will show up in AI answers. It helps AI systems understand your website more clearly, but visibility still depends on stronger signals like website quality, authority, content, reviews, backlinks, Google Business Profile optimization, citations, schema markup, and third-party mentions. The file is helpful, but it is not a magic ranking tool.

5. What should I include in my llms.txt file?

Your llms.txt file should include your business name, website, location, services, service areas, important pages, and a short description of your company. It should also explain how your business should be described. If there is any old or confusing information about your company online, you can include a clarification. Keep it simple, honest, and easy to read. The goal is to help AI systems understand your business accurately, not to stuff keywords or make unsupported claims.
