More than a syntax checker — a complete Google compliance test

Most sitemap validators only check whether the XML is syntactically correct. That's not enough: a sitemap can be valid XML and still be ignored or misinterpreted by Google — due to wrong priorities, invalid lastmod formats, duplicate URLs or foreign domains.

What is checked:

  • →XML Syntax & Encoding — Valid XML, correct UTF-8 declaration and well-formed structure are checked.
  • →Google Limits — Maximum 50,000 URLs and 50 MB per sitemap. Splitting is recommended if exceeded.
  • →Required fields & format — Each entry needs a valid <loc> tag. HTTPS, correct lastmod formats (W3C Datetime), priority between 0.0–1.0 and allowed changefreq values are validated.
  • →Duplicate URLs — Duplicate <loc> entries are detected. They waste crawl budget and are ignored by Google.
  • →Domain consistency — URLs not belonging to the sitemap's domain are flagged as warnings.
  • →Sitemap Index support — Sitemap Index files referencing sub-sitemaps are automatically detected and correctly evaluated.
  • →URL accessibility — A sample of 10–20% of URLs is checked live for accessibility. HTTP status codes like 404 or 301 are shown directly.

Frequently Asked Questions

What does the Sitemap Validator check?+

XML structure, Google compliance (max. 50,000 URLs, max. 50 MB), encoding (UTF-8), lastmod date formats (W3C Datetime), priority values (0.0–1.0), changefreq values, HTTPS URLs, duplicate URLs, domain consistency, sitemap namespace and URL accessibility via sampling.

Is the Sitemap Validator free?+

Yes, completely free and without registration or account. Enter a URL or upload a file — done.

What sitemap formats are supported?+

Standard XML sitemaps (sitemap.xml) and Sitemap Index files are supported. Input via URL or file upload.

How does the URL accessibility check work?+

A random sample of 10–20% of URLs is checked live (minimum 10, maximum 500 URLs). HTTP status codes are shown directly — 200 (OK), 301 (Redirect), 404 (not found) and more.

What does the quality score mean?+

The score of 0–100 evaluates the Google compliance of the sitemap. Each error deducts 20 points, each warning 5 points. From 80 points the sitemap is in good shape, below 50 points there are critical problems that should be fixed.
