What is Indexability?

Indexability is the ability of a page to be added to a search engine’s index and shown in results. Indexability depends on crawlability, canonicalization, and whether the page is allowed to be indexed.

Quick definition

Indexability means whether a search engine can include a page in its searchable database.

How Indexability works

  • Indexability requires that a crawler can access the page (crawlability).
  • Indexability depends on the page being eligible for indexing and not treated as a duplicate.
  • Indexability can be influenced by canonical URL choices.
  • Indexability is affected by technical errors that prevent parsing or rendering.

Why Indexability matters

Indexability matters because a page that is not indexed typically cannot rank.

Indexability also affects AI visibility when AI systems draw from indexed sources.

Example use cases

  • Identifying important pages that are accessible but not indexed.
  • Consolidating duplicates so a single canonical URL is indexed.
  • Fixing server responses that return error codes for crawlers.
