Make ChatGPT Read Your Site in 5 Minutes, No Code

llms.txt is an emerging convention — a plain markdown file at your site's root listing your most important pages in a clean, AI-readable format, similar in spirit to how sitemap.xml works for traditional crawlers.

The fix:

create a plain text file at yourdomain.com/llms.txt listing your key pages as markdown links with one-line descriptions. No code, no build step — just a text file that gives AI systems a fast, structured starting point instead of having to crawl your whole site to figure out what matters.
