AI tools don’t read your website like search engines
AI assistants like ChatGPT and Gemini are changing how people discover websites, services, and products. But they don’t work like search engines.
Search engines crawl and index your entire site. AI tools only scan small parts in real time when responding to a question. As a result, they often miss important information — especially on large or frequently updated websites.
This can lead to answers that are outdated, incomplete, or simply incorrect.
control the narrative, not just rankings.
What is llms.txt?
llms.txt is a new, LLM-friendly markdown file that helps AI tools like ChatGPT, Claude, and Gemini understand your site better, especially when they’re answering questions about it.
Think of it as a map or cheat sheet for AI, showing:
- What your site is about
- Where the important content is
- Clean, plain-text versions of that content (in .md files)
This file isn’t for search engines. It’s for AI assistants trying to give accurate answers based on your content.
AI assistants like ChatGPT can’t understand your whole site
Why it matters
Large language models (LLMs) like ChatGPT can’t read your whole website. They work with limited context and often only access a small portion of your content.
Most web pages are full of extra code and clutter like ads, navigation menus, and scripts. That makes it harder for AI to find the real value. Markdown is simpler. It gives AI a clean, readable version of your content without all the noise.
llms.txt helps AI tools give better answers about your site by pointing them to high-value, plain-text content. It can also reduce the chances of incorrect or misleading responses about your brand.
Who should use llms.txt
This feature is especially helpful if your site has:
- Documentation or help content: If you run a software company with a help center, like a page explaining how to set up your product (e.g. “Getting started with Yoast SEO”).
- Product guides or FAQs
If you have a page that answers common customer questions, like “How to return an item” or “Compare pricing plans”. - Educational articles
If you publish tutorials or explainers, such as “What is structured data?” or “How to improve site speed for SEO”. - Regularly updated blog posts
If your blog covers timely topics, like “Google’s latest algorithm update: What to know in 2025” or “Top 10 SEO tips for ecommerce sites”. - A large amount of content
If you run a news site, university portal, or ecommerce store with hundreds (or thousands) of pages. AI tools can miss key content unless you point them to it directly.
