What does a sitemap validator check?

An XML sitemap tells search engines which URLs to crawl. This validator fetches your sitemap and confirms it's well-formed XML, detects whether it's a urlset or a sitemapindex, counts the URLs, and flags problems like a wrong root element, a non-200 status, an empty file, or exceeding the 50,000-URL / 50 MB limits.

Why a clean sitemap matters

  • A broken sitemap can stop Google discovering new pages.
  • Listing only canonical, indexable URLs improves crawl efficiency.
  • Submit the validated sitemap in Google Search Console.

Frequently asked questions

Where should my sitemap live?

Usually at /sitemap.xml in your domain root, and referenced from robots.txt. Submit it in Search Console too.

How many URLs can one sitemap hold?

Up to 50,000 URLs and 50 MB uncompressed. Beyond that, split it and use a sitemap index.

Will a valid sitemap get my pages indexed?

It helps discovery, but indexing isn't guaranteed. For backlinks on other sites, force-index them with BacklinkIndex.

Does this support sitemap index files?

Yes — it detects both urlset and sitemapindex formats and counts entries.
