XML Sitemap Checker & Validator

Verify that your XML sitemap is accessible, well-formed, and contains the right URLs — so search engines can find and index every page on your site.

What the tool checks

  • Sitemap availability and correct XML format
  • URL count and potential limit violations
  • URL validity and lastmod (last-modified) dates
  • Sitemap index files and nested sitemaps
  • Consistency with the sitemap reference in robots.txt

Why it matters

Your XML sitemap is the definitive list of pages you want indexed. For larger sites it dramatically speeds up content discovery and helps search engines understand your site structure. A broken or outdated sitemap means new pages get indexed slowly — or not at all.

Frequently asked questions

What is an XML sitemap for?

It's a machine-readable list of your website's URLs that helps search engines find and crawl all your important pages, including new or deep content they might otherwise miss.

How many URLs can a sitemap contain?

A single sitemap is limited to 50,000 URLs and 50 MB. For larger sites, use a sitemap index file that links to multiple individual sitemaps.

Where should I host my sitemap?

Typically in the root of your domain (example.com/sitemap.xml). Reference it in both robots.txt and Google Search Console to maximize discoverability.
