🏷️ Hreflang Implementation

HTML Link Elements (Recommended)

<link rel="alternate" hreflang="en" href="https://example.com/page"/>
<link rel="alternate" hreflang="de" href="https://example.com/de/page"/>
<link rel="alternate" hreflang="fr" href="https://example.com/fr/page"/>
<link rel="alternate" hreflang="es" href="https://example.com/es/page"/>
<link rel="alternate" hreflang="x-default" href="https://example.com/page"/>

⚠️ Important: x-default

Always include x-default to specify the default/fallback page for users who don't match any language version.

⚠️ Common Mistakes

🚫 Auto-Redirecting by IP

Automatically redirecting users based on IP blocks Googlebot and frustrates users.

✓ Use language selector banner instead of forced redirects.

🚫 Using Flags for Languages

Flags represent countries, not languages. Spanish is spoken in 20+ countries.

✓ Use language names or globe icons for language switchers.

🚫 Machine Translation Only

Auto-translated content is often low-quality and can hurt rankings.

✓ Use professional translators or at minimum human review.

🚫 Missing Self-Referencing Hreflang

Each page must include an hreflang pointing to itself.

✓ Always include hreflang for current page language.
