AI-powered search engines, like ChatGPT, Gemini and Perplexity are transforming how eCommerce content is discovered. To get ahead of the competition Magento stores need to leverage the AI visibility tools now more than ever.
In this guide, we'll cover one of them, LLMs.txt file in Magento, and explain why it's a part of the Magento SEO best practices and how to generate one step by step. So, your store becomes easier for AI systems to find, understand and cite.
What is the LLMs.txt File?
LLMs.txt file is a structured text document located in the website root directory that contains information about websites' top pages and helps Large Language Models (LLMs) — like ChatGPT and Perplexity — understand your website content better. In other words, it's a contextual map for AI models.
Unlike search engines, AI systems rely on clarity, structure and context rather than crawling and indexing signals. They don't "rank" pages. They synthesise information to reference your store when users search for it.
That means the clearer your positioning and structure, the easier it is fr AI to understand and cite your store.
That is expecially imprant for large, content-rich websites like Magento.
LLMs.txt vs Robots.txt in Magento
Many merchants assume that having a Magento robots.txt file is enough since it already communicates with robots. But robots.txt and LLMs.txt serve entirely different purposes.
Robots.txt is technical. It controls indexing and tells crawlers what they are allowed to access.
LLMs.txt is descriptive, and it doesn't allow or restrict access to pages or files.
LLMs.txt in Magento explains:
- what your website is about
- how your products and services are categorised
- which pages are the most important
- what is your brand about
If robots.txt manages crawling permissions, LLMs.txt manages the understanding of your pages.
Why is LLMs.txt Important in Magento?
For complex Magento websites with deep category hierarchies and thousands of products XML sitemap is usually enough for the structure. But only for traditional search engines.
AI models work differently. They extract and synthesise information based on topical clusters, clear brand definitions, and explicitly stated relationships between products and categories.
LLMs.txt in Magento helps you define those relationships intentionally.
e.g. instead of forcing AI tools to understand what your brand is about from scattered content, you state it explicitly. Through specific categories, products, CMSP pages and other resources in the LLMs.txt file.
In other words, Magento LLMs.txt gives you control over how AI models "see" your store instead of letting them "guess" it from the context they find on the web.
Does LLMs.txt Directly Improve Rankings?
Since LLM systems rely on context and structure rather than crawling and ranking signals, LLMs.txt doesn't work as a direct ranking factor. It doesn't replace technical SEO in Magento or .
However, it improves how AI systems interpret your brand and increases the likelihood of being cited in AI-generated answers. This gives your content AI clarity.
Thus, LLMs.txt is not a shortcut for better ranking in traditional search. It's a strategic structure for the future AI ecosystems.
How to Generate LLMs.txt File in Magento?
There are two main ways to create an LLMs.txt file for Magento: manually and using the Magefan .
The right approach depends on the size of your store, the technical expertise you have and how many pages you want to add to LLMs.txt.
Let’s go step by step.
Create LLMs.txt on the server
If you have some technical knowledge and server access, you can create a file manually.
Step 1: Navigate to your root directory via SSH, cPanel or FTP.
Find your Magento root folder, a place where your robots.txt is stored.
Step 2: Create a new plain text file named LLMs.txt.
Note: make sure the file uses the UTF-8 encoding, contains no HTML and is accessible via the following path — https://yourstore.com/llms.txt (AI systems must be able to access the file publicly).
Step 3: Add structured content to the LLMs.txt file.
It's the most important step. Your Magento LLMs.txt file should contain the following:
- Short description of your website and company
- Main product categories
- Main product or service pages
- Main blog post or category
Here's a simple example of the LLMs.txt structure.
# Store Name: My Magento Store
# Description: A store that sells clothes, gear and shoes for hiking.
## Categories:
- [Category 1](https://yourstore.com/category-1): Category 1 description.
- [Category 2](https://yourstore.com/category-2): Category 2 description.
- [Category 3](https://yourstore.com/category-3): Category 3 description.
## Products:
- [Product 1](https://yourstore.com/product-1): Product 1 description.
- [Product 2](https://yourstore.com/product-2): Product 2 description.
- [Product 3](https://yourstore.com/product-3): Product 3 description.
## Resources:
- [Blog](https://yourstore.com/blog): Blog description.
## Other pages:
- [Other page](https://yourstore.com/other-page): Other page description.
The structure should be simple, concise and context-driven.
Pro tip: Avoid dumping thousands of product URLs here. You have a sitemap for that. It's a guide for an AI system which should focus on clarity and hierarchy.
Step 4: Save and test the LLMs.txt file.
Just open the https://yourstore.com/LLMs.txt in a browser and see if it loads without any redirects or permission errors.
This method of generating LLMs.txt for Magento is enough if you have direct access to the server and don't want to update the file frequently this way.
However, if you prefer to make changes or updates faster, it's better to create LLMs.txt directly from the Magento admin.
Create LLMs.txt in the admin panel
This approach works best for marketers or store owners who want quick access to the LLMs.txt file and extended editing options.
Step 1: Install the Magefan SEO extension for Magento.
Step 2: Create LLMs.txt file in the admin panel.
Note: use the file example from the previous method to create LLMs.txt contents.
Navigate to Stores > Configuration > Magefan Extensions > SEO > AI SEO and paste the content for your LLMs.txt in the Instructions for llms.txt File text field.
Once you save the settings, Magento LLMs.txt becomes available via the following path — https://yourstore.com/llms.txt.
You don't have to test it or worry about editing. Come back to Magefan config any time to add or remove the pages.
Best Practices and Tips for Magento LLMs.txt
As you can see, creating Magento LLMs.txt is relatively simple. Optimising and maintaining is where most stores gain or lose the advantage.
We already know that AI systems rely on clarity, structure and context. That's why optimizing LLMs.txt for that defines how your store will be interreted in generative environments. Let's break down the best practices for that.

Define your niche clearly
The other thing AI focuses on is context. Don't expect it to understand the specialization of your store from products or categories alone. If you have some specific focus, state it clearly in the LLMs.txt.
Well-structured LLMs.txt should clearly cmmunicate your target audience, your expertise and your main product focus.
e.g. [store name] specializes in hiking clothers, shoes or gear for men, women and children.
Keep LLMs.txt updated
AI systems preffer frech content same as the search crawlers. New products are added, products get discontinued. Makes sure you update your positions and pages as your store grows.
Set a schedule to review, update ad regenerate LLMs.txt after some major store changes or content updates.
