Index Coverage Report
The Index Coverage Report is a tool in Google Search Console that shows which pages of a site have been added to Google’s index, which have not, and the reasons why. It helps webmasters and SEO specialists monitor the site’s indexing process, find errors, and optimize page visibility in search.
What is the Index Coverage Report?
The Index Coverage Report is a detailed report that records the status of every page discovered by Googlebot during crawling. It allows you to understand:
- Which pages are already in the index (and may appear in search results).
- Which pages are excluded and why.
- Whether there are technical errors hindering indexing.
- How the number of indexed pages changes over time.
The report helps answer the key SEO question:
“Does Google see my site the way I want it to?”
Where to Find the Index Coverage Report
In the Google Search Console panel:
Index → Coverage
(in newer versions, “Index → Pages”).
Main Statuses in the Report
Google divides pages into 4 categories:
| Category | What it means |
| Error | Pages that were not indexed due to technical issues. |
| Valid with warnings | Pages are indexed but have problems (e.g., incorrect canonical tag). |
| Valid | Pages successfully indexed and available in search. |
| Excluded | Pages that Google intentionally does not index (due to settings or duplicates). |
Details by Category
Error
Google found pages it could not index. Possible reasons:
- Page not available (404 Not Found error).
- Redirect issues (5xx errors, redirect loops, incorrect URL).
- Blocked by the robots.txt file.
- Page loading error (slow server response, timeout).
- A canonical tag points to a non-existent or blocked page.
- What to do: Check HTTP status, redirects, robots.txt, and canonical link settings.
Valid with warnings
Pages were indexed but with potential issues:
- A URL is marked as “noindex” but was indexed anyway.
- Mismatched canonical tags.
- An AMP page with errors was indexed.
- Duplicates without a correct canonical URL.
- What to do: Resolve conflicts between meta tags and canonical pages.
Valid
Pages successfully indexed and can appear in search. These typically include:
- Key target pages (homepage, categories, articles, product pages).
- Pages without errors or restrictions.
- Recommendation: Ensure this category contains only the desired pages, and that duplicates or technical URLs are not indexed.
Excluded
Google intentionally does not index these pages. This isn’t always bad. Possible reasons:
- Duplicate page — duplicate content (a canonical version exists).
- Crawled — currently not indexed — the page was crawled but not yet added to the index.
- Discovered — currently not indexed — the page was found but not yet crawled due to low priority.
- Blocked by robots.txt — blocked from crawling.
- Soft 404 — the page exists, but Google considers it useless (e.g., empty content).
- Alternate page with proper canonical tag — a duplicate correctly linked to the canonical page.
- What to do: Review which pages truly need indexing and which should be intentionally excluded.
How to Use the Report to Improve SEO
- Check for errors regularly. The “Error” tab is the main indicator of a site’s technical problems.
- Monitor trends. An increase in the number of indexed pages indicates site growth. If the number decreases, find the cause.
- Use filters. You can analyze pages by status, error type, or modification date.
- Fix issues and request re-indexing. After fixing an error, click “Validate Fix” in Search Console.
- Synchronize with sitemap.xml. Ensure all pages from the sitemap are actually being indexed.
- Watch for duplicates. If you see many pages labeled “Duplicate, not selected as canonical,” review your structure and canonical tags.
Example
An online store noticed 500 pages in their Google Search Console report with the status “Crawled — currently not indexed.” Analysis revealed these were filtering pages with duplicate content. They were blocked from indexing via noindex, and the sitemap was updated to include only main categories. Within a month, error counts decreased, and organic traffic grew by 12%.
Benefits of Using the Report
- Helps control which pages actually participate in search.
- Allows for quick identification and resolution of errors.
- Improves indexing efficiency and crawl budget usage.
- Provides insight into how Google perceives the site’s structure.
Conclusion
The Index Coverage Report is one of the key tools in Google Search Console, showing the current indexing status of a site. It helps an SEO specialist understand which pages are being indexed correctly and which require fixes.
Regular analysis of the report allows you to:
- Monitor the site’s technical health.
- Improve its structure.
- Ensure steady growth in organic traffic.
A well-configured and “healthy” index is the foundation of successful SEO.
