Indexability

An indexable page generally returns a meaningful successful response, permits crawling, and lacks an applicable noindex directive. Canonicals, duplicates, and quality may affect representation selection. Exact conditions and outcomes depend on the named search engine.

Crawlability describes whether a resource can be fetched, indexability whether it can be considered for an index, and indexed an observed presence in that index. A page may be fetchable yet excluded by a directive, or eligible but not selected for storage.

A new URL returns 200, has a self-canonical, and is not blocked by robots.txt. That supports baseline indexability, but it should not be called indexed until Search Console, Yandex Webmaster, or an observable result provides evidence.

Check the HTTP status, meaningful body without mandatory JavaScript, robots.txt, meta robots and X-Robots-Tag, canonical URL, redirects, and access for the named crawler. Then record URL-inspection evidence for each platform separately, with the observation date.

Even an actually indexed URL may not rank for a target query or appear in an AI feature. Indexability is a readiness layer, not a measure of demand, quality, mentions, or citation.
