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.
SitemapKit's API lets you discover, extract, and parse XML sitemaps from any domain. Get structured JSON data with all sitemap elements including Sitemap Validator.
