How it works

The XML is parsed and checked for urlset namespace, loc elements, URL syntax, size and URL-count limits, and optional lastmod, changefreq, and priority shapes. Sitemap indexes are validated separately from URL sets.

  • Protocol limits are checked before quality warnings.
  • A sitemap can be well-formed XML but still fail SEO expectations.

Worked example

Validate a minimal XML sitemap
Check a single-URL XML sitemap for structural correctness
Input
											<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url><loc>https://example.com/</loc></url>
</urlset>
Output
												Sitemap is valid! Found 1 URL(s).

When to use this

Site deploys, SEO audits, and CI checks validate sitemap files.

Edge cases

  • A loc outside the site can be valid XML but an unwanted target.
  • lastmod needs an accepted date-time form.
  • More than 50,000 URLs or 50 MB requires splitting.
