What is llms.txt and does it help AI find my site?
llms.txt is a plain-text file at the root of a site that gives language models a curated, machine-readable map of who you are and which pages matter. It does not replace robots.txt or sitemap.xml; it supplements them with a summary and an annotated link list, so a model retrieving your site gets structure instead of raw HTML.
This site publishes one at /llms.txt covering the biography, book catalog, FAQ collections, and every post.
Keep it short, factual, and identical in substance to the visible pages it describes.
