Indexed vs. Not Indexed

The distinction between indexed and not-indexed pages is fundamental to understanding search engine optimization. While indexed pages can appear in search results, not-indexed pages remain invisible to users.

What does "Indexed" vs. "Not Indexed" mean?

Indexed Pages

Indexed pages are those that have been discovered, analyzed, and included in the search index by search engine crawlers. These pages have the opportunity to appear in search results when they are relevant to relevant search queries.

Characteristics of indexed pages:

  • Fully captured by crawlers
  • Stored in the search database
  • Can appear in SERPs
  • Visible in Google Search Console

Not Indexed Pages

Not-indexed pages are either not discovered by crawlers or have been deliberately excluded from indexing. These pages do not appear in search results.

Common reasons for not-indexed pages:

  • Technical crawling problems
  • Meta robots tags with "noindex"
  • Robots.txt exclusions
  • Duplicate content
  • Poor page quality
