Understanding Duplicate URLs in Shopify
Duplicate URLs in Shopify occur when multiple URLs lead to the same content. This often happens in collections when products are tagged into multiple categories. These duplicates can confuse search engines, leading to inefficiencies in indexing and negative SEO impacts.
Common Causes of Duplicate URLs
Problems often arise from:
- Multiple tags and categories for single products.
- URL parameters used for filtering and sorting.
- Incorrectly set up redirects or lack thereof.
How to Identify Duplicate URLs
Step 1: Use Google Search Console
Log into Google Search Console and navigate to the 'Coverage' report. Check for indexed URLs that may be duplicates. Look for URLs with query parameters and similar structures.
Step 2: Analyze with Screaming Frog
Run a crawl of your website using Screaming Frog. Filter the results to find URLs with identical content but different paths. This tool will help you pinpoint exact duplicates.

Step 3: Set Up Canonical Tags
In Shopify, navigate to the 'Edit HTML/CSS' section and find your collection.liquid file. Add canonical tags to ensure search engines know the primary URL to index. This tag should point to the main product URL.
Step 4: Use URL Redirects
Set up 301 redirects in Shopify to guide traffic from duplicate URLs to their canonical counterparts. This consolidates authority and improves link equity.
Step 5: Review URL Structures
Ensure your URL structures are clean and descriptive. Avoid unnecessary parameters and ensure all products have a distinct, SEO-friendly path.
