Create an LLMs.txt file, boost SEO, and improve AI interactions.
Large Language Models (LLMs) are AI systems that understand and generate human-like text. They’re used for tasks like answering questions, writing code, or summarizing content. For websites, LLMs can pull information to help users, but they struggle with complex web pages full of menus, ads, and code. Their “context window”—the amount of text they can process at once—is limited, often to a few thousand words, making it hard to grasp an entire site.
Making your website AI-ready can give you an edge. Here’s why:
For example, a developer using an AI tool might need your site’s API guide. If it’s buried in messy HTML, the AI could miss it. An AI-ready site makes that info easy to find, speeding up their work. Similarly, AI chatbots can handle customer questions better if your site’s data is structured for them.
LLMs.txt is a proposed standard to make websites AI-friendly. It’s a markdown file, usually placed at your site’s root (like example.com/llms.txt), that summarizes key content for AI. Unlike robots.txt, which guides search engine crawlers, LLMs.txt helps AI models understand your site’s purpose and find important pages. It often includes a short description and links to main sections, with an optional llms-full.txt for more details.
Creating an LLMs.txt file is easy with free online tools. Let’s explore how to pick one and use it.
Several free tools can generate LLMs.txt files. Here are three popular ones:
Choose based on your needs—Firecrawl for depth, LLMs-txtgenerator for customization, or Writesonic for ease.
Using Firecrawl as an example, here’s how to generate your file:
The process is similar for other tools. LLMs-txtgenerator.org also lets you tweak settings via its API, while Writesonic keeps things straightforward.
Generated files are a great start, but you might want to tweak them. A good LLMs.txt file follows this structure:
For example:
text
# My Website> A platform for learning coding.## Main Documentation- [Getting Started](https://mywebsite.com/start)- [API Guide](https://mywebsite.com/api)## Optional Resources- [Blog](https://mywebsite.com/blog)
Keep it clear, check links, and update it as your site changes. Test it by pasting the content into an AI tool like ChatGPT to see if it understands your site.
To understand the practical impact of LLMs.txt, let’s look at some real-world applications and case studies.
One of the early adopters of LLMs.txt is Anthropic, a company focused on developing reliable, interpretable, and steerable AI systems. Their documentation includes an LLMs.txt file that provides a structured overview of their API and other resources (Anthropic Docs). By implementing LLMs.txt, Anthropic has made it easier for AI models to access and understand their documentation, which in turn helps developers who use AI coding assistants to work more efficiently with Anthropic’s tools.
For instance, when a developer uses an AI assistant like Cursor, they can reference Anthropic’s documentation more effectively, leading to better code suggestions and faster development times. This improved accessibility likely contributes to better user engagement, which could positively impact Anthropic’s SEO as search engines begin to value AI-friendly content.
Another example is Cursor, whose comprehensive llms-full.txt covers various aspects of their product, from billing and dashboard to specific language guides and migration tips (Cursor Docs). This allows AI models to provide detailed and accurate information to users querying about Cursor’s features. For developers, this means quicker access to relevant documentation, reducing time spent searching.
Websites like Mux have also adopted LLMs.txt to improve the user experience with AI tools (Mux Blog). By providing a clear structure of their documentation, Mux ensures that AI assistants can guide users through their platform more effectively, potentially reducing support queries and improving customer satisfaction.
Other companies, like those listed in the LLMs.txt directory (LLMs-txt Hub), show how diverse industries—from tech startups to educational platforms—are using LLMs.txt to enhance AI interactions.
While implementing LLMs.txt offers many benefits, there are also some challenges that developers might face:

By addressing these challenges, developers can maximize the benefits of LLMs.txt for their websites.
As an SEO Manager with 10 years of experience, I’ve seen firsthand how developers are navigating the adoption of LLMs.txt. From discussions on platforms like Hacker News, it’s clear that opinions are mixed. Some developers see LLMs.txt as a valuable tool for making their websites more AI-friendly, while others are skeptical about its necessity or concerned about potential misuse.
For instance, one developer shared, “I created an llms.txt for my site, and it’s been helpful for AI tools to understand my content better. However, I’m concerned about potential misuse.” Another noted, “I’m skeptical about the need for llms.txt since LLMs can already parse websites, but if it helps end-users, I’m all for it.”
These mixed opinions reflect the current state of adoption and acceptance of LLMs.txt in the developer community. However, as AI continues to integrate into daily workflows, tools like LLMs.txt are likely to become more standardized.
Experts like Jeremy Howard, co-founder of Answer.AI, emphasize the importance of LLMs.txt for AI-driven web access (Answer.AI). He argues that as AI models become more prevalent, websites must adapt to ensure their content is easily accessible.
In my experience, I’ve found that early adopters of LLMs.txt are already seeing benefits in user engagement and developer productivity. For example, when working with clients who have implemented LLMs.txt, I’ve noticed improved interaction with AI coding assistants, leading to faster development cycles and better documentation accessibility.
Looking ahead, I believe AI-ready websites will play a bigger role in SEO. As search engines incorporate more AI, sites with structured, AI-friendly content could rank higher, giving early adopters a competitive edge.
In conclusion, making your website AI-ready with LLMs.txt is a strategic move that can enhance user experience, improve SEO, and future-proof your site against the evolving landscape of AI technology. By understanding what LLMs are, why they matter, and how to use free generators to create LLMs.txt, you’re taking a significant step towards optimizing your website for the AI era.
As an SEO Manager, I’ve seen how early adopters of new standards gain a competitive edge. LLMs.txt is no different. It’s not just about keeping up with trends; it’s about positioning your website for success in an increasingly AI-driven world.
