Why Validate Your XML Sitemap?
An XML Sitemap acts as a guide for search engines, leading them to your most important content. However, a single syntax error can render the entire file unreadable to Googlebot, causing significant indexing issues. This validator ensures your file meets the strict standards of the Sitemap Protocol.
Common Sitemap Errors
- XML Syntax: Missing closing tags, unescaped characters (like `&` instead of `&`), or incorrect encoding headers are fatal errors.
- Limit Violations: A single sitemap file cannot contain more than 50,000 URLs or exceed 50MB in uncompressed size. Larger sites must use a Sitemap Index.
- Date Format: The
<lastmod>tag requires W3C Datetime format (YYYY-MM-DD). Using US format (MM/DD/YYYY) or omitting the year will cause validation warnings. - Invalid Values:
<priority>must be between 0.0 and 1.0.<changefreq>must match one of the seven allowed values (e.g., 'daily', 'weekly').
Understanding the Score
100/100 (Perfect): No syntax errors, all URLs are valid, constraints are met, and all optional tags are formatted correctly.
80-99 (Good): File is readable, but contains minor warnings (e.g., HTTP links in an HTTPS sitemap).
< 80 (Critical): Major syntax errors or constraint violations preventing the sitemap from functioning.
