Paste XML or provide a public sitemap URL before submitting it to a search engine. The validator reports structural issues and identifies the affected entries. It accepts both URL sets and sitemap indexes.

A structurally valid sitemap can still list redirected, blocked, or non-canonical pages. Check those separately in your crawler or search console.
