The root element and namespace, that every entry has an absolute http or https URL with & escaped as &, that lastmod uses the W3C date format and is not in the future, duplicate URLs, URLs on more than one host or scheme, and the limits of 50,000 URLs and 50 MB per file.

Is it a full XML validator?

No. It reads the sitemap's elements, which is where nearly all sitemap mistakes are. A file that is not well-formed XML can still be refused by Google even when this check finds its entries.

Does Google use changefreq and priority?

No. Google ignores both. It does use lastmod when the dates are consistently accurate, so a lastmod that changes on every build teaches Google to ignore it.

How do I find a site's sitemap?

Try /sitemap.xml, then look for a Sitemap: line in /robots.txt. To list a site's pages from its sitemaps and links in one go, use the free page finder.

Error (line 7) - An & in this URL is not escaped. Write it as &.

Warning (line 7) - lastmod "01/10/2026" is not a W3C date such as 2026-10-20 or 2026-10-20T09:30:00+00:00.

Note - Google ignores <changefreq> and <priority>. They do no harm, and an accurate <lastmod> is what it reads.

A sitemap is a list, not a guarantee

Google treats a sitemap as a hint about which URLs exist. A listed page that redirects, answers with an error, carries noindex or names another canonical will not be indexed because it is listed.

Comparing the sitemap with the pages the site actually links to finds both kinds of gap: pages nothing links to, and pages the sitemap forgot. Find all pages on a site.

Questions

No. You paste the XML and the check runs in your browser as you type, so it works on a sitemap you have not published yet. Nothing you paste is sent to domscout.
