Frequently Asked Questions

What does an llms.txt validator check?

It checks whether a public llms.txt file has a brand summary, preferred citation, AI answer page, machine-readable index, best pages to cite, stable facts, common answers, sitemap, freshness cues, and safe public URLs.

Does llms.txt guarantee ChatGPT, Claude, or Perplexity traffic?

No. It is a source map, not a ranking guarantee. It works best alongside crawlable pages, strong internal links, visible answer blocks, structured data, source clarity, and real off-site corroboration.

Should private app pages be listed in llms.txt?

No. Keep admin, account, dashboard, checkout, API, staging, and customer-private routes out of public AI citation files. Public source pages and public tools should be easy to discover; private surfaces should remain protected.
