Question 1

What is llms.txt?

Accepted Answer

llms.txt is a plain-text Markdown file placed at the root of your website (e.g., yoursite.com/llms.txt). It gives AI language models a concise, structured summary of your site's content — similar to how robots.txt guides search engine crawlers, but designed specifically for LLMs.

Question 2

Why do I need llms.txt?

Accepted Answer

LLMs often struggle with modern websites because of JavaScript-rendered content they can't easily parse, navigation menus, ads, and boilerplate drowning the real content, and no clear signal about what pages matter most. llms.txt solves this by giving the model a clean, curated index of your most important content.

Question 3

How is it different from robots.txt or sitemap.xml?

Accepted Answer

robots.txt allows or blocks crawlers for search bots, sitemap.xml lists all URLs for search engines, while llms.txt provides a curated content summary for AI and LLMs. They're complementary — you'd typically have all three.

Question 4

What is llms-full.txt and do I need it?

Accepted Answer

llms-full.txt is an optional companion file containing the full content of your key pages — everything an LLM would need without following links. Use it if your documentation is extensive and you want AI tools to have offline access. For most small sites, just llms.txt is enough.

Question 5

Where do I place the file on my website?

Accepted Answer

The file must be accessible at the root of your domain: https://yoursite.com/llms.txt. For static sites (Netlify, Vercel, GitHub Pages), place it in your public/ or root output folder.

Question 6

Does it affect SEO or search rankings?

Accepted Answer

No. llms.txt is not read by Google or other traditional search engines — it's aimed at AI assistants and tools. It won't help or hurt your search rankings. It's purely for improving how AI models understand and reference your content.
