How llms.txt differs from LLMO, GEO, robots.txt
robots.txt controls crawl policy. llms.txt provides ingest-friendly context — a curated Markdown overview of the site for LLMs that have already been allowed to read.
How Mentionwell handles llms.txt
- Site-wide /llms.txt and /llms-full.txt published at the canonical paths on every Mentionwell deployment.
- Per-article .md mirrors at <path>.md so any LLM can ingest a clean Markdown version of any page.
- Files are regenerated on every publish so the corpus stays fresh.
