Validate any XML sitemap — check structure, count URLs, detect errors, and inspect sitemap index files. Enter a sitemap URL or a domain to auto-detect.
/sitemap.xml automaticallyAn XML sitemap is a file that lists all the pages on your website you want search engines to discover and index. It helps crawlers find pages that might not be easily discoverable through internal links. Most websites place their sitemap at /sitemap.xml.
A single XML sitemap can contain a maximum of 50,000 URLs and must be under 50MB uncompressed. For larger sites, use a sitemap index file that references multiple individual sitemaps. Our validator checks both single sitemaps and sitemap index files.
A sitemap index file is a sitemap that lists other sitemaps rather than individual URLs. Large sites use them to split their URLs across multiple sitemap files. The index file typically lives at /sitemap.xml and references files like /sitemap-posts.xml, /sitemap-pages.xml etc.
Google may ignore sitemap URLs that return 4xx/5xx errors, have canonical tags pointing to different URLs, are blocked by robots.txt, or redirect more than once. Use our Redirect Checker and Meta Tag Checker alongside the Sitemap Validator for a complete SEO audit.
