Sitemap Validator — Free XML Sitemap Validation Tool
Validate your XML sitemap against the sitemaps.org protocol with clear pass/fail results and actionable fixes.
A sitemap with structural errors won't be read correctly by Google — even if it looks fine to you. This sitemap validator checks your XML against the official sitemaps.org protocol and returns a detailed error report, flagging exactly what's wrong and how to fix it.
Common issues it catches: malformed XML, missing required elements, invalid URL formats, duplicate entries, incorrect namespace declarations, and changefreq or priority values outside the allowed range.
Use this after generating or editing a sitemap, before submitting to Google Search Console, or as part of a regular SEO audit.
