XML Sitemap Checker

XML Sitemap Checker fetches a sitemap URL, validates that it is well-formed XML, and reports on structure, URL counts and common issues that keep search engines from using it properly. Whether you’re auditing your own site or a client’s, this page explains the xml sitemap checker concept end-to-end and, gives you a free, working free xml sitemap checker below.

How it works

Paste a sitemap URL (a urlset or a sitemap index). We fetch and parse the XML, count <url> or <sitemap> entries, check namespaces, and flag missing <lastmod>, oversized files, or entries that look unreachable.

What we check

• Valid, well-formed XML
• Sitemap index vs. single urlset
• Total URL count (Google's soft limit is 50,000 URLs / 50MB uncompressed per file)
• Presence of <lastmod> dates
• Obvious duplicate or non-canonical URLs

How to fix common XML Sitemap Checker issues

1. Split sitemaps that exceed the URL/size limits using a sitemap index.
2. Add accurate <lastmod> values so crawlers can prioritise re-crawls.
3. Remove noindexed, redirected or 404 URLs from the sitemap.
4. Reference the sitemap in robots.txt and submit it in Google Search Console.
