Validate sitemap.xml files and sitemap indexes before submission so search engines receive clean XML, valid URLs, and properly structured entries.

How to use Sitemap Validator
Drop in page URLs, metadata, markup, or audit exports into the tool above, inspect the result, and reuse clear recommendations you can push back into templates or CMS fields. If you are checking an edge case, start with "Does this tool support sitemap indexes as well as normal sitemaps?" and verify the output against that scenario.
When this tool is useful

- QA CMS or build-step sitemap output after a routing or localization change.
- Check duplicate loc entries, malformed lastmod values, or protocol mistakes in client sitemaps.
- Review sitemap indexes before large content launches or localization rollouts.
Practical tips
- Validate the file structure first, then separately verify that important URLs return healthy indexable pages.
- Keep each sitemap safely below the 50,000 URL and 50 MB uncompressed limits.
- Use sitemap indexes when your site grows beyond a single clean sitemap file.
- Keep low-value URLs out of the sitemap instead of treating the sitemap as a full URL dump.
