XML Sitemap Validator

Paste your sitemap XML and get a clear pass or fail report — well-formedness, urlset structure, valid loc URLs and the 50,000-URL limit.

— What it does

The XML Sitemap Validator is a free tool that checks a sitemap.xml against the sitemaps.org rules so search engines can crawl it cleanly. It confirms the XML is well-formed, that the root is a <urlset> or <sitemapindex>, that every <url> has a single valid http(s) <loc>, and that the URL count stays within the 50,000-URL guideline — then returns a pass or fail report of every issue. All parsing runs in your browser, so your sitemap is never uploaded.

  • Checks well-formed XML and reports the parser error if it is malformed.
  • Verifies a <urlset> or <sitemapindex> root and that each entry has a valid <loc>.
  • Flags non-http(s) and malformed loc URLs and counts total URLs against the 50,000 limit.
  • Runs entirely in your browser — your sitemap is never uploaded to a server.

How to use it

1

Paste your sitemap XML

Copy the full contents of your sitemap.xml (or sitemap index) and paste it into the input box.

2

Read the report

The validator instantly checks structure and every loc, then lists each issue it finds with a pass or fail summary.

3

Fix and re-check

Correct any flagged URLs or structure, paste the updated XML, and confirm it passes before you submit it.

Frequently asked

Is my sitemap uploaded when I validate it?
No. The XML is parsed entirely in your browser with the built-in DOMParser. Your sitemap is never sent to a server, so it is safe to check private or unpublished sitemaps.
What does this validator check?
It checks that the XML is well-formed, that the root element is a <urlset> or <sitemapindex>, that every entry has exactly one <loc>, that each loc is a valid absolute http or https URL, and that the total URL count stays within the 50,000-URL guideline.
Why does my sitemap fail well-formedness?
Usually an unescaped ampersand or angle bracket in a URL, a missing closing tag, or stray text before the XML declaration. The report shows the parser message so you can locate it.
What is the 50,000-URL limit?
A single sitemap may list up to 50,000 URLs and must be under 50 MB uncompressed. If you have more, split them into several sitemaps and reference each one from a sitemap index file.
