Sitemap Validator
FreeValidate XML sitemaps for errors and proper structure
About Sitemap Validator
Search engines lean on your XML sitemap to discover pages, but one malformed tag or an oversized file can make a crawler skip the whole thing. Sitemap Validator parses your sitemap and flags structural problems — invalid XML, missing required elements, bad URL formatting, or entries that break the protocol — so you catch issues before they cost you discovery.
Submit a sitemap URL and the tool fetches and validates it against the sitemap spec directly in your browser, then reports errors and warnings line by item. It is completely free with no login and returns results instantly. Run it after generating or regenerating a sitemap to be sure crawlers can actually read it.

FAQ
Does it validate a sitemap index with multiple files?
It checks the sitemap you submit for valid structure. For an index, confirm the index parses and that each referenced sitemap is itself valid.
Does a valid sitemap guarantee indexing?
No. A clean sitemap helps discovery, but indexing depends on content quality, crawl budget, and other ranking factors.
Will it tell me if the listed URLs are reachable?
Its focus is XML structure and protocol compliance. Treat broken-link checking as a separate step.
Can I use Sitemap Validator on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
