Sitemap XML Validator
Validate your sitemap.xml file for errors, check URL count, namespaces and compliance with search engine requirements.
What do we validate?
Our tool performs a comprehensive validation of your sitemap.xml file against all major requirements.
XML Structure & Syntax
We verify that your sitemap is well-formed XML, uses the correct sitemaps.org namespace, and follows the proper element structure.
URL Validation
We check all URLs for proper formatting, detect duplicates, and verify the total count stays within the 50,000 URL limit per sitemap.
Size & Limits
We verify file size stays under the 50MB uncompressed limit and URL count within 50,000 entries as required by search engines.
Optional Tags Analysis
We check for lastmod, changefreq and priority tags. While optional, these help search engines crawl your site more efficiently.
What is Sitemap XML?
A sitemap.xml file is an XML document that lists all important URLs on your website. It helps search engines like Google, Bing and Yahoo discover and index your pages more efficiently. The sitemap protocol was created by Google and is now supported by all major search engines.
Why validate your sitemap?
An invalid sitemap can prevent search engines from properly indexing your pages. Validation ensures your sitemap follows the correct XML syntax, uses proper namespaces, stays within size limits, and contains valid URLs. This helps maximize your search engine visibility and crawl efficiency.
