Meta AI search index; blocking removes you from Meta AI answers
Almost never block
meta-webindexer builds and refreshes the index behind Meta's AI answers. Blocking it is the most expensive mistake in AI SEO: you disappear from Meta citations while your training decision stays completely separate.
If you need to protect specific sections (pricing, docs), use path-scoped rules instead of a blanket Disallow: /.
