Validate XML sitemap structure client-side — paste your sitemap XML to check for urlset tags, loc elements, URL count, and common formatting issues. No data is sent to any server.
Frequently Asked Questions
What does the Sitemap Validator check?
It verifies basic XML structure — well-formed markup, a urlset root element, loc tags inside url entries, URL count, and whether loc values look like valid absolute URLs.
Does this validate sitemap index files?
This tool focuses on standard urlset sitemaps. Sitemap index files use sitemapindex instead of urlset and are flagged with a warning.
Is my sitemap sent to a server?
No. All validation runs entirely in your browser using the DOMParser API.
How do I tell search engines about my sitemap?
Add a Sitemap directive to your robots.txt using the Robots.txt Generator, or submit the sitemap in Google Search Console.
Is this tool free and does it work on mobile?
Yes on both counts. The Sitemap Validator on draft21 is completely free with no sign-up required and works on all devices.
