How to use the XML sitemap checker

An XML sitemap checker verifies that search engines can discover the important URLs on your website. Clarity checks whether a sitemap exists, whether it contains valid URLs and whether common signals like lastmod, HTTPS and duplicates look healthy.

What Clarity checks

  • โœ“Common sitemap locations such as /sitemap.xml and sitemap indexes
  • โœ“URL count, duplicate URLs, HTTP vs HTTPS and lastmod coverage
  • โœ“Empty sitemap files and oversized sitemap warnings

Common issues found

  • !New pages not submitted to Google because the sitemap is stale
  • !Duplicate, HTTP or outdated URLs wasting crawl budget
  • !Sitemap indexes that exist but hide broken child sitemaps

Example action

Example: after publishing a new AI SEO page, your sitemap should include the canonical HTTPS URL and a recent lastmod date so discovery is not left to chance.

Frequently asked questions

Do I need a sitemap for SEO?

Most websites benefit from a sitemap because it gives search engines a clean list of canonical URLs to crawl and revisit.

What makes a sitemap healthy?

A healthy sitemap uses canonical HTTPS URLs, avoids duplicates, includes important indexable pages and stays updated when content changes.

Should every URL be in a sitemap?

No. Only include canonical, indexable URLs that you actually want search engines to discover and rank.
