Enter a sitemap URL (or just your site URL) and our XML sitemap checker fetches the sitemap.xml, detects whether it's a sitemap index or a urlset, and validates the structure and entries.
What is an XML sitemap checker?
An XML sitemap checker is a free tool that loads a site's sitemap.xml, parses it, and reports what it contains. It works as an XML sitemap validator and sitemap validator tool — paste a URL to check a website's sitemap.xml in seconds, no signup.
Validate your sitemap.xml
Use it as a sitemap file checker: we fetch the file (falling back to the Sitemap:line in robots.txt if needed), detect whether it's a sitemap index or a urlset, count the entries, and flag structural problems. It's the quickest website XML sitemap checker for confirming a sitemap is well-formed.
Sitemap index vs urlset
A urlset lists your actual page URLs; a sitemap index lists other sitemap files. Large sites split URLs across many sitemaps and reference them from one index. This xml site checker reads both and tells you which kind you have.
Why XML sitemaps matter for SEO
A valid, current sitemap helps search engines discover and prioritize your pages — especially new, deep, or poorly-linked URLs. Keeping it error-free and declaring it in robots.txt and Google Search Console makes crawling more efficient, which is why an SEO sitemap checker belongs in every technical audit.

An XML sitemap checker is a free tool that fetches a site's sitemap.xml, parses it, and reports what it contains — whether it's a sitemap index (a list of other sitemaps) or a urlset of page URLs, how many entries it holds, and any structural problems.

A urlset is a sitemap that lists actual page URLs (<url> entries). A sitemap index (<sitemapindex>) lists other sitemap files instead — large sites split their URLs across many sitemaps and reference them all from one index. This sitemap validator tool detects which kind you have and reads both.
Conventionally at the domain root (example.com/sitemap.xml) and declared in robots.txt with a Sitemap: line, plus submitted in Google Search Console. The checker looks in those places automatically when you give it a site URL.
