Sync HTML canonical tags and Link headers

Conflicting canonical-url signals can lead search engines to ignore both declarations, potentially causing duplicate content issues and incorrect indexing.

Quick Reference

• Ensure the rel="canonical" tag in your HTML matches the Link canonical-url header if both are used
• Avoid sending conflicting signals to search engines about the primary version of a page
• Maintain consistency across all methods of declaring your canonical URL

Check

Compare the HTML canonical tag with the HTTP Link header to ensure they point to the exact same URL.

Fix

Update either the HTML tag or the HTTP header so that they provide a consistent canonical URL signal.
