Sitemap Validator
Test your XML for strict protocol compliance. Paste a URL or raw code to validate tags, size limits, and formatting instantly.
Strict XML Sitemap Tester & Rules
Our validator checks your file against the official sitemaps.org protocol. A valid format ensures that search engines like Google and Bing can process your links without errors.
Protocol Limits Enforcement
Search engines have strict size limits. This tool checks that your file does not exceed the absolute limit of 50MB (uncompressed) and that it contains no more than 50,000 URLs. If you exceed these limits, you must split your file into a sitemap index.
Hybrid Server and Client Execution
You can test your sitemap in two ways:
- URL Mode: Enter your website address and our tool will auto-discover the file and test it from our server.
- Code Mode: Paste your raw XML directly into the tool to test it instantly in your browser without sending data to our servers.
Granular Tag Analysis
This tool parses your XML line by line to detect missing closing tags, stray characters, and incorrect schema declarations. It also validates individual tags:
- Priority: Checks that the value is between 0.0 and 1.0.
- Changefreq: Ensures the value matches allowed terms (always, hourly, daily, weekly, monthly, yearly, never).
- Lastmod: Validates the date format (YYYY-MM-DD).
