Question 1

What is llms.txt?

Accepted Answer

llms.txt is a markdown file at the root of your domain that tells large language models what your site is about and which pages are worth reading. It plays the role robots.txt plays for search crawlers: a single, predictable place to state what matters. It is a community proposal rather than a ratified standard, and support varies by engine.

Question 2

Does llms.txt actually affect whether AI engines cite me?

Accepted Answer

No engine has committed publicly to reading it, so treat it as cheap insurance rather than a ranking lever. What reliably helps is the underlying work it forces: naming your canonical pages, describing each one in a sentence, and being explicit about which URL answers which question.

Question 3

Where do I put the file?

Accepted Answer

Serve it at https://yourdomain.com/llms.txt as plain text. On Next.js you can generate it from a route handler so it stays in sync with your real page list instead of drifting, which is how the file on this site is built.

Question 4

What is the difference between llms.txt and llms-full.txt?

Accepted Answer

llms.txt is the index: a short summary plus annotated links. llms-full.txt is the full text of that content concatenated into one file, so an assistant can ingest everything in a single fetch. Publishing both is common; the index is the one to start with.
