Understanding Sitemap Validation
Pre-Submission Check
Catch structural errors before submitting your sitemap to Google Search Console or Bing Webmaster Tools.
Debugging Generated Sitemaps
Verify a sitemap produced by a CMS plugin or custom script actually conforms to spec.
Full Field Validation
Checks required <loc> tags, valid URL format, and correct <changefreq>/<priority> values.
Local Processing
Your sitemap content never leaves your browser — validation runs entirely client-side.
What This Validator Checks
Per the sitemaps.org protocol, this tool confirms the root <urlset> element declares the correct namespace, every <url> entry has a valid <loc>, optional <changefreq> values are one of the seven allowed frequencies, optional <priority> values fall between 0.0 and 1.0, and the sitemap doesn't exceed the 50,000 URL limit per file.
Key Takeaways
- Specific Errors: Get a numbered list of exactly which URL entries have problems.
- Protocol-Accurate: Validates against the official sitemaps.org 0.9 schema rules.
- Client-Side Only: All validation happens locally in your browser — no data is ever sent to a server.
