Full definition
A page can be crawlable yet non-indexable—for example when meta robots or X-Robots-Tag include noindex, when the URL returns an error, or when it is a thin duplicate the engine chooses not to keep. Indexability combines technical permission (robots rules, headers) with quality and canonical choices.
Teams audit indexability to ensure money pages can enter the index while staging, filters, and private paths stay out. Search Console coverage-style reports and crawl tools surface blocked or excluded URLs.
AI answer systems that rely on retrieval still need discoverable, indexable (or otherwise fetchable) public URLs as grounding material. Blocking or noindexing primary docs can shrink AI visibility even when the site “works” for logged-in users. See noindex, robots.txt, and Soft 404.
