XML Sitemap Checker
Enter a sitemap URL to validate its XML and inspect its URLs, lastmod values, duplicates, and structure.
What this checks
This tool fetches the sitemap URL you enter, confirms it's well-formed XML, and identifies whether it's a URL sitemap or a sitemap index. For a URL sitemap, every <loc> and <lastmod> is extracted, with duplicate and invalid URLs flagged. Sitemap indexes list their child sitemaps without automatically fetching each one, keeping this check bounded.
