About this tool
Validate sitemap.xml files and sitemap indexes before submission so search engines receive clean XML, valid URLs, and properly structured entries.
This SEO tool is built for pre-publish QA and implementation support rather than vague optimization advice. It helps teams check one search-facing signal cleanly before a page, template, or release goes live.
- Checks XML syntax and sitemap root types like urlset and sitemapindex.
- Validates absolute loc URLs, duplicate entries, lastmod values, changefreq values, and priority ranges.
- Flags entry-count and raw file-size issues against core sitemap limits.
How to use Sitemap Validator
Enter the relevant metadata, markup, URL set, or export data into the tool above, then review the checks and corrected output. Use the result to fix the source template, CMS field, or deployment rule before shipping changes.
When this tool is useful
- Validate a generated sitemap.xml before submitting it in Google Search Console.
- 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.
Why people use this tool
