Sitemap validator

Paste a sitemap and find the errors that make a search engine reject the whole file.

These generators run in your browser, so they need JavaScript enabled. Everything explained on this page is still readable without it.

XML is not forgiving: a single raw & in a URL makes the document malformed, and a search engine discards all of it rather than the one line. That is the most common sitemap fault by a wide margin, and it is the first thing checked here.
