Sitemap Validator
Validate an XML sitemap (or sitemap index): format, sitemaps.org rules and the referenced child sitemaps.
About this tool
The Sitemap Validator checks that an XML sitemap (or a sitemap index) meets the sitemaps.org format and rules: well-formed URLs, size limits, correct tags and the referenced sub-sitemaps. It is the step before submitting it to Google Search Console.
- Validate XML syntax and structure against the sitemaps.org standard.
- Follow sitemap indexes and review each sub-sitemap.
- Detect malformed URLs or ones exceeding the allowed limits.
Frequently asked questions
How many URLs fit in a sitemap?
A sitemap allows up to 50,000 URLs and 50 MB uncompressed. If you need more, split them into several sitemaps linked from a sitemap index.
How often should I update the sitemap?
Whenever you add, remove or change important URLs. If your site is dynamic, generating it automatically on every deploy keeps it always reflecting the real content.
