XML Sitemap Validator
A broken or malformed sitemap can quietly stop search engines from discovering your pages. Paste your sitemap.xml content below to check it's well-formed XML and follows the sitemap protocol — missing <loc> tags, invalid URLs, duplicates, and the 50,000 URL per-file limit. Everything runs in your browser — nothing is uploaded anywhere.
Validation runs entirely in your browser — nothing is uploaded.
Paste sitemap XML above to validate it.
Frequently asked questions
Where do I get my sitemap XML to paste in?
Open your sitemap URL (e.g. yoursite.com/sitemap.xml) in a browser, view page source, and copy the full contents.
What's the maximum size for a sitemap?
Per the sitemap protocol, a single sitemap file can list at most 50,000 URLs and must be no larger than 50MB uncompressed — larger sites need a sitemap index referencing multiple files.
