How can merchants avoid duplicate content issues?

Merchants can reduce duplicate content issues by making sure search engines can clearly identify the preferred version of similar or localized pages.

Key practices include:

• Use canonical URLs for pages with substantially similar content.
• Implement hreflang tags for different language or regional versions.
• Use consistent 301 redirects when URLs are permanently moved.
• Avoid creating unnecessary duplicate URLs or URL parameters.
• Provide unique, useful content for important pages where appropriate.
• Use Shopify Markets’ localized domains, subdomains, or subfolders consistently.
• Keep internal links pointing to the preferred versions of URLs.

For international Shopify stores, correctly combining canonicalization and hreflang is especially important. Hreflang tells search engines about alternative language or regional versions, while canonicalization identifies the preferred URL.
