XML Sitemap Checker
Paste your sitemap XML to validate it, count URLs and catch common problems. Parsed locally in your browser.
Limits per the sitemaps.org spec: max 50,000 URLs and
50 MB uncompressed per file; use a sitemap index for more.
In Joomla, sitemaps usually come from an extension (e.g. OSMap, JSitemap) — point
Google Search Console at the sitemap URL once it validates.
