What is Website Indexability? Issues, Causes & Fixes (2026)
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
noindex meta tag
A <meta name="robots" content="noindex"> tag explicitly tells Google not to index the page.
robots.txt Disallow
A Disallow rule in robots.txt blocks Googlebot from crawling the page entirely.
Conflicting canonical tags
If page A has a canonical pointing to page B, Google will index B instead of A.
Thin or duplicate content
Google may choose not to index pages it considers low-quality or lacking unique value.
