XML Sitemap Validator
Validate XML sitemaps for correct format, valid URLs and SEO best practices.
Parse Error
Failed to parse XML.
Validate your sitemap.xml against the sitemaps.org protocol. Paste your XML to instantly check for missing <loc> tags, invalid changefreq values, out-of-range priorities, duplicate URLs, malformed dates, and more.
Key Features
Full XML parse
Uses the browser's native DOMParser to perform a real XML parse — catches malformed XML before checking sitemaps-specific rules.
Per-URL issue reporting
Every issue is linked to the specific URL entry it affects, so you can jump straight to the problematic line in your sitemap.
Errors vs warnings
Critical violations (missing loc, invalid priority, wrong changefreq) are flagged as errors; less severe issues (long URLs, format quirks) are warnings.
Parsed URL table
After validation, all URL entries are displayed in a table showing loc, lastmod, changefreq, and priority — invalid values are highlighted in red.
