Executive Summary

Core Insights

  • Indexability is the set of conditions that determine whether Google stores a page in its search index.
  • Crawlability (access) is a prerequisite for Indexability (storage).
  • Common critical barriers include noindex tags and robots.txt disallow rules.
  • High-severity issues include conflicting canonical tags and thin or duplicate content.
  • SiteGrip's audit tool flags these issues by severity and enables direct API-based resubmission.

A page is only useful for SEO if Google adds it to its search index. Indexability is the set of conditions that determine whether Google will store a page after crawling it. If a page isn't in Google's index, it cannot rank — no matter how good the content is.

Crawlability vs. Indexability

These two terms are often confused. Crawlability is whether Googlebot can physically access the page (not blocked by robots.txt or a server error). Indexability is whether, after crawling it, Google decides the page is worth storing. A page can be crawlable but not indexable, but it cannot be indexable without first being crawlable.

Common Indexability Issues

Critical

noindex meta tag

A <meta name="robots" content="noindex"> tag explicitly tells Google not to index the page.

Critical

robots.txt Disallow

A Disallow rule in robots.txt blocks Googlebot from crawling the page entirely.

High

Conflicting canonical tags

If page A has a canonical pointing to page B, Google will index B instead of A.

High

Thin or duplicate content

Google may choose not to index pages it considers low-quality or lacking unique value.
