FAQ
Common questions about the XML Sitemap Validator.
What does the validator check?
It checks your XML sitemap for valid syntax, required tags like urlset, url and loc, correct namespace, counts total URLs, and highlights any XML parsing errors or structural warnings.
Is lastmod required?
No. The sitemaps.org protocol requires only <loc> inside each <url>. lastmod, changefreq and priority are optional but recommended.
How accurate is the validation?
The validator uses the browser's XML parser to confirm well-formedness, then runs the sitemaps.org rules for structure, namespaces and per-URL elements.
Is my sitemap data uploaded to a server?
No. All validation happens entirely in your browser. Your XML data never leaves your device.
