Sitemap Validator
Validate XML sitemap structure online and review URLs, required fields, limits, and indexing guidance.
Make HTML structure easier to inspect
This tool reviews sitemap XML for structural and content issues and presents findings that may affect processing. A valid sitemap document is a hint for crawlers, not a guarantee that URLs will be crawled or indexed. Search engines apply their own policies and limits.
Formatting is not HTML validation
An XML sitemap lists URLs and optional metadata such as last modification time, change frequency, and priority. Sitemap index files can reference other sitemaps. XML syntax, URL limits, host rules, encoding, and supported metadata all matter.
How to format HTML
- Paste sitemap XML or provide its content, run validation, and inspect parser errors, URL values, namespaces, and limits. Check that URLs use the intended host and protocol, return appropriate responses, and are reachable to the target crawler.
- Paste sitemap XML or provide its content, run validation, and inspect parser errors, URL values, namespaces, and limits. Check that URLs use the intended host and protocol, return appropriate responses, and are reachable to the target crawler. Compare validated URLs with the published site.
Formatting method
- Read markup structure
The validator parses XML, checks sitemap namespaces and element structure, examines URL formats and counts, and reports warnings or errors. It may not fetch every URL or know the policies of every search engine. Metadata such as priority is not a ranking command.
- Apply indentation
The validator parses XML, checks sitemap namespaces and element structure, examines URL formats and counts, and reports warnings or errors. It may not fetch every URL or know the policies of every search engine. Metadata such as priority is not a ranking command.
- Preserve content
The validator parses XML, checks sitemap namespaces and element structure, examines URL formats and counts, and reports warnings or errors. It may not fetch every URL or know the policies of every search engine. Metadata such as priority is not a ranking command.

Read the formatted result
A useful result separates XML validity, sitemap protocol issues, URL quality, and operational warnings. Check duplicate URLs, redirects, canonical targets, lastmod accuracy, file size, and index references before publishing.
Common mistakes
Common mistakes include listing blocked or non-canonical URLs, mixing hosts, using invalid dates, exceeding limits, claiming a sitemap guarantees indexing, and forgetting to submit or reference the sitemap at the correct property.

Limits and special cases
The validator cannot guarantee crawler access, indexing, canonical selection, freshness, server response, or search visibility. Large files, compressed delivery, indexes, and platform-specific rules require deployment checks.
