What Are Hreflang Tags and Why They Matter for International SEO
Hreflang tags are HTML attributes or annotations that specify the language and optional region of a webpage. Google uses these signals to match users with the correct page version, improving relevance and reducing duplicate content issues.
Language Targeting vs Country Targeting
- Language targeting: Ensures content is shown in the correct language regardless of country.
- Country targeting: Ensures content is shown to users in a specific country, even if multiple regions speak the same language.
Hreflang is critical for multilingual or multi-regional websites because it:
- Prevents duplicate content issues
- Increases click-through rates (CTR) in SERPs
- Enhances user experience
Common scenarios for hreflang include: international eCommerce sites, global blogs, or corporate websites serving multiple regions.
How Hreflang Tags Work in Google Search
Search engines read hreflang annotations to serve the appropriate page.
Key points:
- Relationship with canonical tags: Hreflang signals do not replace canonical tags but work alongside them to indicate the preferred URL.
- What hreflang does not do: It does not directly boost rankings or change page authority.
- Supported search engines: Google, Bing, and Yandex honor hreflang; others may vary.
