Sitemap XML validator
Paste a direct link to your sitemap or sitemap index. We fetch the file and score it against the official sitemaps.org rules your crawlers expect.
Expert Sitemap protocol validation
A sitemap is how you tell crawlers what to discover. Perfect Metadata parses the fetched XML directly and audits it against the published sitemaps.org rules—not guesswork about your stack.
Structural audit
We load your file as XML and verify the root element, namespace declarations, mandatory <loc> URLs, enumerated changefreq values, sane priority decimals, uncompressed size cues, and the documented 50k entry cap—all without executing JavaScript from your domain.
