What if the tool says “Invalid XML”?
This means your sitemap file exists but has formatting errors.
Common causes:
- Broken XML syntax (missing closing tags, special characters)
- File isn’t actually XML (HTML error page instead)
- Corrupted file
- Character encoding issues
How to fix:
- Visit your sitemap URL directly in a browser
- Check if it displays as XML or shows an error
- Use an XML validator tool to check syntax
- If using a plugin, try regenerating the sitemap
- Contact your web developer if the issue persists
