The AI search engine optimization is revolutionizing digital marketing. It's no longer enough to just appear on Google: now it's also we want them to find us through ChatGPT, Gemini or Perplexity.
To make your business stand out in this new environment, the llms.txt file becomes a key piece of informationhelps artificial intelligences understand your website and know what information to display about your company.
What is the LLMS file?
The llms.txt file is a text document, usually in Markdown format, which is placed at the root of the website (for example: https://tusitio.com/llms.txt) and which is designed to guide large language models (LLMs - Large Language Models) about how your website is structured, what content is key, and how they can use it or not.
Unlike classic files such as robots.txt (which give search engines indications on what to crawl or not) or sitemap.xml (which list relevant URLs), llms.txt is designed for understanding by AI, so that the models can better “understand” your site, its logic, its content hierarchy, which parts you want to be used in automated responses, etc.
What is it for and why is it important?
The llms.txt serves as a map so that ChatGPT, Gemini, Claude and other engines can identify and recommend relevant content for your business. Its main utilities are.
Prioritize relevant content
You decide which parts of your website are most important. For example, you can indicate that the “Services” section is key, while the “Cookies policy” or “Legal notice” pages are not a priority.
Improves reading comprehension and speed
AIs have “context window” limitations.” (the amount of text they can process at the same time). If your website has many pages, menus, scripts or ads, the AI can get lost. The llms.txt file makes it easier for the AI to have a clear map of what it needs to see, speeding up its understanding.
Optimization for AI, not just traditional search engines
It no longer matters only how you rank in Google. With llms.txt, your site gain visibility on conversational engines or agents that rely on LLMs, increasing the chances that your content will be cited or used in autoresponders.
Control over the use of your content
You can also choose what content you do not want an AI to use for learning or as a source of answers. This is especially useful if you want to protect internal materials, private documentation or sections that should not be disseminated.
How to create LLMS.txt step by step
As mentioned above, the llms.txt file must be a plain text file in Markdown format, which allows structuring the information in a clear and readable way, both for humans and artificial intelligences.
With Markdown you can define titles, subtitles, lists and links in a simple way, without adding unnecessary code. that may confuse AI agents or slow down their interpretation. For example, the symbols # are used to create title hierarchies:
- #: indicates a main title
- ##: one caption
- ####: a lower level, and so on
This helps the information is organized and AIs easily understand which parts are most important within the file.
Before creating it, it is advisable to plan the key sections of your website and decide which content you want to highlight (services, products, resources, contact details...) and which is not a priority. Here you have an example of a well-structured llms.txt

To create the llms.txt, first it is recommended to plan the key sections of your site and decide which content you want to highlight and which you can leave out. Use descriptive titles, short descriptions and direct links that make it easy for AIs to interpret.
When creating it, you can choose one of the following options tools:
If your website is developed with WordPress
The plugin Yoast SEO has already incorporated llms.txt file compatibility. From its configuration panel you can generate and customize the content of the file so that it is automatically updated according to your pages and entries.
There are also other complements such as Website LLMS.txt o LLMS.txt AI Generator available in the official WordPress repository, which allow for more advanced content customization.
If you have an online store with PrestaShop
Although it is relatively recent, there are already compatible modules such as LLMS Generator - Index your PrestaShop AI-Friendly. This module automatically generates the llms.txt file for your store and allows you to easily configure it from the administration panel. It is an ideal option if you manage an online store with a large catalog and want to save time in the implementation.
Other platforms (Shopify, Magento, etc.)
In these cases, there are still no official tools that generate the llms.txt automatically, so the best alternative is to create it manually. This way, you maintain full control over what information you include and how it is interpreted by the AI. Need help with this? Contact with us and we will help you.
In any case, before implementing it, we recommend that you prove that the file is accessible publicly and is not blocked by the robots.txt file.
Key parts that your llms.txt should include
Your file must contain at least:
- Name and description: a brief summary explaining the objective and main offer of your business.
- Contact information: physical address, telephone numbers, e-mail and office hours to facilitate direct conversion.
- Important services and products: listing with direct links and clear descriptions of each solution you offer.
- Resources and guides: articles, tutorials or technical documentation that reinforce the relevance and authority of your brand in front of AIs.
- Frequently asked questions and relevant policies: practical information on shipping, returns, customer service and legal terms, so that the AI can resolve users' doubts.
- Social networks: links to official profiles.
- Awards and certifications: accreditations, professional certifications or recognitions that reinforce your company's authority.
- Main structured data: include information such as Organization (name, description, logo, address, contact) and WebPage (URL, title, description, language) so that the AI can correctly interpret the structure of your website.
