💡 Best Practices
  • Consistency: Use the same canonical URL pattern across your entire site
  • Self-referencing: Every page should have a canonical tag, even if it points to itself
  • HTTPS: Always prefer HTTPS in canonical URLs for security and SEO
  • Absolute URLs: Always use absolute URLs (with protocol and domain) in canonical tags
  • Parameters: Remove tracking parameters (utm_*, ref, etc.) from canonical URLs
  • Duplicates: Point duplicate/similar content pages to the preferred version
