Implementation note
Keep the file curated.
Start with the pages that explain the product, service, documentation, policies, and examples. Exclude login pages, carts, search results, tag archives, duplicate pages, private URLs, and other low-value resources. Validate the file, then place it at your domain root as /llms.txt.
Common states to handle
Invalid or private URL
Block localhost, private networks, metadata endpoints, and non-http protocols.
Blocked by robots.txt
Respect robots rules and allow manual URL input when crawling is restricted.
Download success
Copy or download the file, then verify the public root path.
