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.
Frequently Asked Questions
- What does this tool validate?
- Whether the XML is well-formed, whether it's a urlset or sitemap index, and lists the URLs it contains.
- Can I check just a homepage URL?
- Yes — enter a homepage and the tool automatically looks for /sitemap.xml or a robots.txt sitemap declaration.
- What's the difference from Sitemap URL Extractor?
- This validates the sitemap; the Sitemap URL Extractor is optimized for exporting large URL lists (search, filter, CSV/TXT download).
