What Is Indexing?

SEO

Updated 18 September 2026

Quick Answer

Indexing is when a search engine stores a crawled page in its database, making it eligible to appear in search results — a page must be indexed before it can rank for anything.

Indexing vs. Crawling — What's the Difference?

Why It Matters

  • A page that's crawled but not indexed still can't appear in search results at all, regardless of content quality.
  • Checking indexing status is a basic, essential diagnostic step whenever a page isn't showing up in search.

How It Works

  1. A search engine's crawler discovers and reads a page.
  2. If the page meets basic quality and technical criteria, it's added to the search engine's index.
  3. Only indexed pages are eligible to be shown in response to a relevant search.

Key Takeaways

  • Indexing means a page is stored and eligible to appear in search results.
  • A crawled but unindexed page still can't rank for anything.
  • Google Search Console is the direct way to check indexing status.

Frequently Asked Questions

How do I check if my page is indexed?

Google Search Console shows indexing status directly, or you can search 'site:yourdomain.com/page-url' to check manually.

Why would a page not get indexed?

Common causes include thin or duplicate content, accidental blocking (via robots.txt or a noindex tag), or the page simply not yet being crawled.

How long does indexing take after publishing a new page?

It varies, often from a few days to a few weeks, though submitting a sitemap can help speed up discovery.
