Question

Where do you submit llms.txt?

There is no central registry or submission tool for llms.txt. You publish it at https://yourdomain.com/llms.txt, link to it, and let crawlers discover it. Unlike IndexNow for URLs, there is no official place to "submit" the file.

Correct setup

  1. Place the file at the site root: /llms.txt.
  2. Link it from your footer and reference it where relevant.
  3. Keep the linked URLs returning HTTP 200 and canonical.
  4. Re-submit those URLs via IndexNow when they change (that reaches Bing/ChatGPT).

Verify it is live

curl -I https://yourdomain.com/llms.txt
