XML Sitemap Validator & Indexability Checker
Test XML sitemaps and sitemap indexes, verify URL formatting, check lastmod timestamps, and discover indexation barriers.
Overview & Why This Matters
An XML Sitemap provides search engines like Google and Bing with a comprehensive roadmap of all canonical pages on your website. Validating your sitemap ensures that newly published URLs are discovered rapidly and crawl budget is not wasted on broken or redirecting links.
Why XML Sitemap Health is Crucial for Indexation
Accelerate New Content Discovery
Search engines discover fresh articles and landing pages within hours when published in a valid, frequently updated sitemap.
Optimize Search Engine Crawl Budget
Submitting accurate <lastmod> dates ensures crawlers spend resources only on pages that have actually changed since the last visit.
Detect Broken & Redirecting URLs
Sitemaps containing 404 errors or 301 redirect chains waste crawler quota and hurt technical indexation signals in Search Console.
Standard Sitemap 0.9 XML Structure
Ensure your sitemap adheres to the official sitemaps.org protocol specification:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<url>
<loc>https://example.com/page-url/</loc>
<lastmod>2026-09-27</lastmod>
<changefreq>weekly</changefreq>
<priority>0.8</priority>
</url>
</urlset>
