Rank Math showing duplicate meta tags (like title, description, or canonical) in your HTML source code typically happens due to theme/plugin conflicts, incorrect SEO settings, or multiple output triggers. This guide walks you through 7 proven fixes with scripts, screenshots, and debugging tactics.

🚨 1. Identify the Duplicate Tags

First, confirm which tags are duplicated:

1. View your page source (Ctrl+U):

   • Search for <title>, meta name="description", or rel="canonical".

2. Note the duplicates:

<!-- Example Duplicates --> 
<title>Page Title - Site</title> 
<title>Page Title - Site</title> <!-- Duplicate! --> 

🔧 2. Disable Conflicting Theme/Plugin Output (Most Common Fix)

Why it happens:
Your theme or another plugin (e.g., Yoast, All in One SEO) might be generating meta tags independently of Rank Math.

How to fix:

1. For themes:

   • Go to Theme Settings → SEO Options (in themes like Astra, Divi, Avada).

   • Disable: Meta Tags, Open Graph, and Canonical URL settings.

2. For plugins:

   • Deactivate plugins one by one (especially SEO plugins) using Plugins → Installed Plugins.

   • After each deactivation, check your source code.

⚙️ 3. Reset Rank Math’s Advanced Settings

Misconfigured modules cause double-tagging:

1. Go to Rank Math SEO → Dashboard.

2. Under Advanced, disable these temporarily:

   • Schema Markup

   • Open Graph

   • Twitter Card

3. Clear caches and recheck.
