A tool that checks an XML sitemap for errors, schema compliance, and best practices.
A sitemap validator checks XML sitemaps for correctness, including:
- **XML well-formedness** — Proper XML syntax, encoding, and structure - **Schema compliance** — Adherence to the Sitemaps.org XSD schema - **URL validity** — All URLs are absolute, properly encoded, and accessible - **Size limits** — File size under 50MB, URL count under 50,000 - **Content type** — Correct MIME type (`application/xml` or `text/xml`)
Google Search Console acts as a built-in validator — it reports sitemap errors like unreachable URLs, invalid dates, and schema violations.
SitemapKit's extract endpoint also performs validation during parsing and reports structural issues in the response.
