Questions
Can't find your answer? The help center covers every part of the report, or ask us directly.
What is llms.txt?
A proposed plain-text index of your key pages for language models, served at yourdomain.com/llms.txt. It starts with a # title and a > summary, then lists links under ## sections.
Does it improve AI visibility?
Not much yet. Major engines rarely read it and Google has said it does not use it. It is quick to add and does no harm.
Should it replace my sitemap?
No. Your XML sitemap is still what search engines use to find pages.
