Sitemap Validator
Paste your sitemap.xml (or sitemap index) to validate its structure, count URLs and catch the errors that stop Google from crawling it.
🔒 Runs entirely in your browser · nothing is uploaded or stored

- Max 50MB uncompressed
- Use a sitemap index beyond that
- All URLs must be absolute & same host
✅ Best practice

lastmod(real dates) - List canonical URLs only

- Submit in Search Console
Frequently Asked Questions
Can it fetch my sitemap by URL?
Cross-origin fetching is blocked by browsers for security, so paste the XML directly (open yoursite.com/sitemap.xml and copy it). Validation runs entirely in your browser.
What's a sitemap index?
A sitemap that lists other sitemaps. Use one when you exceed 50,000 URLs or 50MB — each child sitemap stays within the limits.
