What are canonical vs. hreflang tags, and when should each be used?

Asked on Sep 27, 2025

Answer

Canonical and hreflang tags serve different purposes in SEO, helping search engines understand content relationships and language targeting. Canonical tags indicate the preferred version of a webpage to avoid duplicate content issues, while hreflang tags specify the language and regional targeting of a webpage.

Example Concept: Canonical tags are used to signal the "master" version of a page when similar or duplicate content exists across multiple URLs, helping consolidate ranking signals. Hreflang tags are used to inform search engines about the language and regional targeting of a page, ensuring users are directed to the most appropriate version based on their language and location.

Additional Comment:

Use canonical tags when you have duplicate or similar content across different URLs to consolidate link equity and avoid duplicate content penalties.
Implement hreflang tags when you have multiple versions of a page for different languages or regions to ensure users are served the correct version.
Canonical tags are placed in the section of a webpage using the format.
Hreflang tags can be placed in the section or in the HTTP header, using the format.
Both tags help improve user experience and search engine understanding, but they address different aspects of SEO.
