llms.txt vs llms-full.txt: which to use
llms.txt is a concise markdown file at /llms.txt with a title, summary, and links to priority URLs. llms-full.txt is a related convention for longer excerpts or expanded context some teams publish separately. Neither replaces robots.txt, crawl access, or strong HTML. Google does not require either file for Search generative features when content is crawlable and helpful. Choose llms-full.txt only if you can maintain accuracy; otherwise stay with a lean llms.txt.
Most small businesses should master a short llms.txt first. Longer files drift out of date faster and create maintenance risk without guaranteed AI benefit.
| File | Typical use |
|---|---|
| llms.txt | Short map: summary + links to key public pages. |
| llms-full.txt | Longer excerpts when you have an owner and update process. |
| Neither | Substitutes for allowing GPTBot-class crawlers or honest on-page copy. |
