Indexability
Whether a page is eligible to be added to a search engine index. A page can be crawlable but not indexable if it is blocked by meta directives.
Indexability is controlled by robots meta tags ("index, follow" vs "noindex"), canonical tags, and HTTP headers. A noindex page is crawled but excluded from search results.
Common indexability mistakes: noindex left on in production after staging, canonicals pointing to wrong pages, robots.txt blocking pages that should be indexable.
