Bounded structural diagnostics
XML Sitemap Validator
Paste or upload sitemap XML to check its structure, namespace, URL entries, dates, priorities, and protocol limits. CorrectSitemap does not fetch or host your sitemap.
Check the XML you already have
The validator handles submitted urlset and sitemapindex documents. Sitemap indexes are checked as documents; linked child sitemaps are not fetched.
Focused troubleshooting
Invalid sitemap XML
Malformed tags, unsafe declarations, missing locations, and broken values.
Namespace errors
Why a well-formed XML file can still fail the sitemap protocol.
Sitemap index errors
Check index structure and child sitemap locations without fetching them.
Working with other structured formats?
Check calendar files with CorrectICS, contact files with CorrectVCF, feeds with CorrectFeed, Content-Type values with CorrectMIME, or browse CorrectFormats.
