| Data Point | Example Value |
|---|---|
| Total URLs in Scope | 1200 |
| Covered URLs | 930 |
| Valid URLs | 880 |
| Excluded URLs | 210 |
| Error URLs | 60 |
| Submitted Sitemap URLs | 900 |
| Indexed URLs | 840 |
| Target Crawl URLs | 1100 |
| Crawled URLs | 980 |

Main Formula: Coverage Percentage = (Covered URLs / Total URLs in Scope) × 100
Uncovered URLs: Total URLs in Scope − Covered URLs
Valid Share: (Valid URLs / Covered URLs) × 100
Exclusion Rate: (Excluded URLs / Total URLs in Scope) × 100
Error Rate: (Error URLs / Total URLs in Scope) × 100
Sitemap Indexation Rate: (Indexed URLs / Submitted Sitemap URLs) × 100
Crawl Reach: (Crawled URLs / Target Crawl URLs) × 100
Priority Coverage: (Covered Priority URLs / Priority URLs) × 100

Coverage percentage shows how much of your website content is reachable, valid, and visible within your audit scope. This metric helps technical SEO teams spot weak sections. It highlights pages missed by crawlers, excluded from indexing, or blocked by quality issues. A coverage rate often supports better discovery, cleaner reporting, and smarter optimization priorities.
This tool compares covered URLs against total URLs in scope. It can also review indexed pages, submitted sitemap URLs, crawl targets, priority pages, exclusions, and error counts. That wider view matters. A single percentage alone can hide serious gaps. Advanced coverage analysis shows whether your site structure, internal linking, and crawl paths are supporting search visibility.
Good coverage improves workflow decisions. You can find missing landing pages, thin content clusters, redirect chains, parameter duplicates, and broken sections. You can also compare sitemap submissions with indexed pages to detect waste. When coverage is low, teams often need better linking, cleaner canonicals, stronger templates, and improved status code control. These fixes can reduce crawl friction and increase page discovery.
Use this calculator during site migrations, content pruning, index audits, and recurring health checks. Measure priority URL coverage separately from coverage. That keeps revenue pages in focus. Track changes over time after technical fixes. Compare valid, excluded, and error percentages together. This creates a balanced view of site health. It also makes reporting easier for clients, stakeholders, and in-house SEO teams.
A high percentage is useful, but context matters. Review uncovered URLs carefully. Check whether they should be indexed, improved, redirected, or removed. Study excluded and error trends before making broad decisions. Strong coverage comes from consistent templates, clean architecture, fast crawling, and controlled index signals. Use the result here as a starting point, then investigate the pages behind the number.
Agencies use coverage percentage in monthly reports. Publishers use it for archive cleanup. Ecommerce teams use it for category audits. SaaS teams use it during migrations. The metric stays simple, clear, and useful across technical, content, and growth workflows every day.
Coverage percentage shows how many URLs are covered within your chosen scope. In SEO, it helps measure discovered, valid, or indexed pages against the total target URL count in an audit.
Total URLs in scope and covered URLs are required. All other fields are optional, but they help you inspect validity, exclusions, crawling depth, sitemap indexation, and priority page performance.
Yes. That usually means your inputs conflict. Your covered count may include duplicates, out-of-scope pages, or a total scope that is too small for the current audit dataset.
Excluded URLs explain why some pages are not part of final coverage. They can reveal noindex rules, canonicals, redirects, duplicates, soft issues, or intentional exclusions in your technical setup.
Crawl reach compares crawled URLs against your target crawl set. It helps show whether bots or audit tools are actually reaching the pages you expect them to discover.
Priority coverage focuses on high-value pages only. This can include product pages, service pages, category pages, or lead pages. It helps teams protect revenue-driving sections before less critical content.
Use it during technical SEO audits, migrations, content cleanups, sitemap reviews, index checks, and monthly performance reporting. It is also useful after major template or internal linking changes.
CSV is useful for spreadsheets and quick team analysis. PDF is useful for snapshots, client reports, and simple sharing when you want a fixed summary of the current audit result.
