Sitemap XML Validator
Validate your XML sitemap structure and check for common issues. Paste your sitemap.xml or fetch it by URL, see a live count of valid URLs, and catch errors before search engines crawl, no code, no signup.
Enter a URL to automatically fetch and validate its sitemap.xml file
Paste your sitemap.xml content or load a sample to validate
Runs entirely in your browser — the validator never sends what you paste to a server.
How it works
Validate your sitemap in three steps
Paste or fetch your sitemap
Paste your sitemap.xml content, or enter a URL to fetch it automatically. Load a sample sitemap or sitemap index if you just want to see how it works.
Run the validator
We check that the XML parses, that the root is a valid <urlset> or <sitemapindex>, and that each entry carries a <loc> and well-formed metadata, fully in your browser.
Fix and ship
Errors and warnings are listed issue by issue, with a live count of valid URLs, so you can patch your sitemap and re-validate until it passes, then submit it with confidence.
Common questions about XML sitemaps
An XML sitemap is a structured file that lists the important URLs on your site so search engines can discover and crawl them efficiently. It uses a defined schema (a <urlset> root with <url> entries, each carrying a <loc>) and can optionally include metadata like <lastmod>, <changefreq>, and <priority>.
At minimum a <urlset> root with the sitemaps.org namespace and one or more <url> entries, each with a <loc> holding an absolute URL. Optional per-URL elements are <lastmod> (W3C datetime), <changefreq>, and <priority> (0.0-1.0). A sitemap index uses a <sitemapindex> root with <sitemap> entries instead.
A single sitemap file can contain up to 50,000 URLs and must be no larger than 50MB uncompressed. If you exceed either limit, split your URLs across multiple sitemaps and reference them from a sitemap index file (<sitemapindex>).
Include the canonical, indexable pages you want search engines to rank, and leave out noindex pages, duplicates, redirects, and low-value or utility URLs. A focused sitemap of high-quality pages helps crawlers spend their budget where it matters.
