What is the maximum size of an XML sitemap?
Standard XML sitemaps are limited to 50,000 URLs and an uncompressed file size of 50MB. If your sitemap exceeds these limits, you must split it into multiple sitemaps and use a sitemap index file.

What is a sitemap health check?
A sitemap health check reviews the XML file search engines use to discover your URLs. It checks whether the sitemap is valid XML, whether URLs are secure, whether duplicate entries exist, whether lastmod coverage is strong, and whether the file stays inside standard sitemap size limits.
How to get better output
Paste a sitemap URL or raw XML into the tool. The checker fetches the file, validates the XML structure, counts URLs, flags HTTP entries, detects duplicates, measures lastmod coverage, and returns a health score with explicit warnings.
