About This Check

Checks whether your sitemap content looks like valid XML rather than an HTML error page. HTML responses often mean misconfiguration or a redirect challenge.

Why This Matters

LLM Discoverability

Invalid or HTML-wrapped sitemaps are ignored by XML-parsing crawlers; AI systems that retrieve sitemaps programmatically will silently discard malformed documents.

SEO Impact

Googlebot validates sitemap XML before processing; an invalid sitemap produces errors in Search Console and means the submitted URL list is never used to guide crawling.
