Validate any XML sitemap. Check for errors, see URL counts, file size, response time, and metadata coverage — all for free.
A sitemap checker (or sitemap validator) analyzes your XML sitemap to ensure it follows the sitemap protocol. It verifies the XML is well-formed, the root element is correct, and all URL entries include a valid <loc> tag.
Beyond validation, our checker reports on metadata coverage — how many of your URLs include lastmod, changefreq, and priority tags. This helps you identify gaps in your sitemap that could affect how search engines crawl your site.
We fetch your sitemap URL and measure the response time and file size.
We parse the XML and verify the root element, URL entries, and structure conform to the sitemap protocol.
We calculate the percentage of URLs that include lastmod, changefreq, and priority metadata.
A sitemap checker validates your XML sitemap by verifying it is well-formed XML, has the correct root element (<urlset> or <sitemapindex>), and contains valid URLs. It also reports metadata coverage for lastmod, changefreq, and priority tags.
Yes. You can validate up to 3 sitemaps per hour without creating an account. For unlimited checks and API access, sign up for a free API key.
Metadata coverage shows what percentage of URLs in your sitemap include optional XML tags like <lastmod> (last modification date), <changefreq> (change frequency), and <priority>. Higher coverage gives search engines more information about your pages.
According to the sitemap protocol, a single sitemap file should contain no more than 50,000 URLs and should not exceed 50 MB uncompressed. If you have more URLs, use a sitemap index file to reference multiple sitemaps.
