llms.txt the robots.txt for AI

Just as robots.txt tells search engine crawlers which pages to index, llms.txt is a plain text file that tells large language models what your site is about, what content is available, and how it should be understood. It sits at the root of your domain yourdomain.com/llms.txt and is readable by both AI systems and humans.

The standard was proposed in 2024 (it is not an official, universally recognized standard like a W3C standard at this time) and is gaining rapid adoption. Tools like Claude, Perplexity, and AI-powered search systems are beginning to use it as a structured signal for site-level understanding complementing page-level signals like JSON-LD schema and meta tags.

A well-written llms.txt gives AI systems a direct, authoritative overview of your site written by you, not inferred from your HTML.

Why you should add llms.txt to your site

Better AI understanding
LLMs that process your site can read your llms.txt first and get an accurate, structured overview reducing misattribution and improving citation accuracy.
Entity verification signal
An llms.txt file confirms that a real, organized entity is behind the site the same trust signal that About and Contact pages provide, but for AI systems specifically.
Early mover advantage
Most sites still don't have an llms.txt. Implementing it now puts you ahead of the majority of the web for AI discoverability and it takes under 30 minutes.
Guides AI to your best content
Instead of letting AI systems guess which pages are most important, you explicitly tell them pointing to your key pages, tools, and resources.

How this generator works

01
Enter your site details
Provide your site name, URL, a brief description, and optionally your name and contact email. These form the header of your llms.txt and tell AI systems who is behind the content.
02
Fetch your sitemap
Enter your sitemap URL and the generator fetches up to 200 URLs from it. It supports standard sitemaps, sitemap index files, and any URL that returns valid XML regardless of file extension.
03
Select the pages that matter
Choose which pages to include. You don't need every URL focus on your homepage, key service or content pages, about page, and any tools or resources. 5–15 pages is the recommended range. You can optionally add a short description for each.
04
Download and upload
Download the generated llms.txt file and upload it to the root of your domain. On Cloudflare Pages or GitHub Pages, place it in the root of your repository. The file should be accessible at yourdomain.com/llms.txt.

What a good llms.txt looks like

The llms.txt format is intentionally simple plain text with Markdown-like structure. It starts with a title and description, followed by sections with links and optional notes. Here is an example:

# My Site Name

> A brief description of what the site does and who it is for.

## Pages

- [Homepage](https://example.com/)
- [About us](https://example.com/about): Who we are and what we do.
- [Blog](https://example.com/blog): Articles on our main topic.
- [Contact](https://example.com/contact)

## About

- Author: Your Name
- Website: https://example.com
- Contact: hello@example.com

Keep descriptions concise and factual. Avoid marketing language write for machines that need to understand your content accurately, not for humans you're trying to persuade.

Common questions

Does llms.txt affect my Google ranking?
No. Google does not use llms.txt as a ranking signal. It is specifically designed for large language models and AI retrieval systems, not traditional search engines.
How often should I update it?
Update it when you add significant new content or tools, rename or restructure key pages, or change your contact information. There is no need to update it for every minor content change.
Do I need to include every page?
No and you shouldn't. The purpose of llms.txt is to highlight your most important pages, not to replicate your sitemap. Focus on the pages that best represent what your site is and does.
Is llms.txt an official standard?
It is a proposed community standard published at llmstxt.org, not a formal W3C or IETF specification. Adoption is growing rapidly, but implementation details may evolve. The format used by this generator follows the current llmstxt.org specification.
How does this affect my LLM Visibility Score?
The hey-eye Analyzer checks for the presence of a valid llms.txt file as part of the Authority & Trust pillar, which accounts for 20% of the total score. A valid llms.txt earns +5 points in that pillar.
