Rank Math canonical URL problems typically stem from plugin conflicts, incorrect settings, theme overrides, or conflicting SEO tools. Follow these 7 proven fixes to resolve “duplicate canonical tags” or “wrong canonical URLs” permanently.

🔍 1. Identify the Issue (Quick Diagnosis)

First, confirm the error:

1. View page source (Ctrl+U) → Search for canonical

2. Look for:

   • Multiple canonical tags

   • Incorrect URLs (e.g., HTTP vs HTTPS, wrong pagination)

<!-- ERROR EXAMPLES --> 
<link rel="canonical" href="http://site.com/page" /> <!-- HTTP --> 
<link rel="canonical" href="https://site.cxxom/page" /> <!-- HTTPS (correct) --> 

🛠️ 2. Configure Rank Math Canonical Settings

Critical settings:

1. Go to Rank Math SEO → Titles & Meta → Global Settings

2. Verify:

   • ✅ Canonical URL set to Open Graph URL

   • ✅ Auto-generate Canonical URL enabled

   • ❌ Remove Add Canonical Link if duplicates persist

3. For paginated content:

   • Enable Add rel="prev" & rel="next"
