Direct answer
llms.txt is a proposed file that gives AI systems a compact map of useful site content. A WordPress site may use it as an optional navigation aid for tools that read it, but it should not be treated as a ranking guarantee or a replacement for useful pages, robots.txt, sitemap.xml or structured data.
Why it matters
This answer supports question-led SEO without relying on outdated rich-result tactics. It should answer one real search intent, add judgement and caveats, and avoid creating shallow pages for every keyword variation.
What to check
- Does the page answer a distinct question, not a keyword variation?
- Does it add examples, caveats and original judgement?
- Is Article + BreadcrumbList more appropriate than FAQ or QAPage markup?
Common mistake
Writing a thin page for every query variation or assuming schema guarantees search visibility.
Caveats
Medium caveat risk: use careful wording and recheck current, technical, platform, service-scope or public-account claims before publication. Keep the answer framed as guidance rather than a guarantee.
