llms.txt and robots.txt Change Monitor
Monitor changes to an existing llms.txt file, robots.txt file, or public llms.txt directory. Review changed descriptions and links in llms.txt, published user-agent rules in robots.txt, or new directory listings. These observations do not establish whether an AI system used the site or how it ranks.

Can I monitor a missing llms.txt file?
This setup needs a readable starting page. If /llms.txt returns 404, monitor a public directory or documentation page that would list it, then review newly added links. Do not assume that a missing file has been saved as a working monitor.
What does an llms.txt change tell me?
It shows a change to the publisher's content guidance or links. Files may be generated by a publishing platform, so presence alone does not prove AI investment, crawler use, citations, or improved rankings.
How is robots.txt different?
robots.txt declares instructions for named crawlers and paths. llms.txt provides content guidance and links. Track the visible text separately and verify any access or visibility impact with the relevant crawler and analytics tools.
