Optimizing URL Structure and Hreflang Implementation for US and Canada in a Single Domain: Best Practices and Considerations
Managing a multilingual website or a site serving multiple regional audiences on a single domain presents unique challenges and opportunities. A common scenario involves serving the United States and Canada from a shared domain, with varying URL structures and backlink profiles. In this article, we explore strategies for optimizing URL structure and hreflang implementation to preserve SEO equity, improve crawl efficiency, and ensure a smooth user experience.
Scenario Overview
Suppose your website operates under a single domain, targeting both US and Canadian audiences. Your current URL setup resembles the following:
- US Pages: /product-1/, /product-2/
- Canadian Pages: /locations/product-1-canada/, /locations/product-2-canada/
Additionally, a significant portion of backlinks point directly to the Canadian URLs under the /locations/…-canada/ path. Your goals include:
- Preserving link equity from existing backlinks
- Minimizing search engine crawl overhead
- Avoiding temporary errors such as 403 or 503 during structural changes
- Implementing hreflang annotations correctly for en-us and en-ca
Key Questions and Strategic Options
1. Will maintaining a mixed URL structure (US at root, Canada under /locations/) harm SEO compared to normalizing URLs to /canada/product-2/?
Generally, having a mixed URL structure is acceptable if properly annotated with hreflang tags and internal links are consistent. Search engines understand that different URLs may represent regional versions, especially with appropriate hreflang and canonical tags. However, overly complex URL structures can potentially dilute link equity and cause confusion if not managed carefully.
2. What are the implications of migrating Canadian URLs from /locations/…-canada/ to /canada/…-product/?
The migration process, involving 301 redirects from legacy URLs to new canonical URLs, can have several impacts:
- Ranking: Properly executed redirects typically preserve rankings if URL changes are clean and all signals (canonical, hreflang, sitemaps) are updated accordingly.
- Crawl Budget: Simplified, cleaner URLs can improve crawl efficiency, especially if internal linking is reorganized to favor the new structure.
- Backlinks: Maintaining existing backlinks pointing to legacy URLs is critical. Redirects ensure backlink equity is preserved.
- Risks: During migration, there may be temporary fluctuations, so thorough testing and monitoring are advised.
