Free Sitemap Checker: Validate Your XML Sitemap for SEO

Your XML sitemap is a roadmap for search engines — it tells them which pages to crawl and how often. A broken sitemap means search engines might miss your most important content, while a bloated sitemap wastes crawl budget on low-value pages.

Citedy's free Sitemap Checker validates your XML sitemap and flags issues that could hurt indexing.

How It Works

  1. Visit citedy.com/tools/sitemap-checker
  2. Enter your sitemap URL (usually domain.com/sitemap.xml)
  3. Get validation results for format, URLs, and best practices
  4. Fix issues based on specific recommendations

Key Features

  • XML format validation — Ensure your sitemap follows the sitemap protocol specification
  • URL status checking — Verify all URLs return 200 status codes
  • Duplicate URL detection — Find URLs listed multiple times
  • Lastmod date validation — Check that dates are properly formatted and realistic
  • Size limit check — Flag sitemaps exceeding the 50,000 URL or 50MB limits
  • Sitemap index support — Validate sitemap index files with sub-sitemaps
  • Orphan page detection — Find important pages missing from the sitemap

Use Cases

After site launches: Verify the sitemap includes all important pages and no test/staging URLs.

Indexing troubleshooting: When new pages aren't getting indexed, a broken sitemap is often the cause.

Regular maintenance: Quarterly sitemap validation catches drift as pages are added and removed.

CMS migrations: Ensure the new CMS generates correct sitemaps with proper URLs.

vs Paid Alternatives

Screaming Frog ($259/year) and Sitebulb ($35/mo) include sitemap validation in site audits. Citedy's tool provides focused sitemap checking for free — no software installation required.

FAQ

How large should my sitemap be?

Keep it under 50,000 URLs and 50MB per file. For larger sites, use a sitemap index file to reference multiple sub-sitemaps.

Should I include every page in my sitemap?

Include only pages you want indexed. Exclude paginated pages, filter pages, admin pages, and thin content pages.

How often should I update my sitemap?

Your CMS should auto-generate sitemaps when content changes. If manual, update weekly or whenever you publish new content.
