Sitemap Validator
Validate sitemap.xml against the protocol and inspect every URL inside.
🔒 XML is parsed entirely in your browser.
What gets checked
- Well-formed XML and correct root element (
urlsetorsitemapindex) - Required
<loc>on every entry, and that it parses as an absolute URL - Optional fields:
lastmod(W3C datetime),changefreq,priority(0.0–1.0) - Per-file caps from the sitemap protocol: ≤50,000 URLs, ≤50 MB uncompressed
Paste the contents or drop the file. Fetching a remote sitemap by URL is blocked by CORS in most browsers — save it locally first.
