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

Real-World Case Studies
How top brands chose their international SEO structure
📖 Amazon: ccTLD Strategy
Structure: amazon.com, amazon.fr, amazon.de, amazon.co.uk
Why: Each market has dramatically different product catalogs, pricing, fulfillment networks, and regulatory requirements. Local trust is critical for e-commerce.
Results: Dominates local search in every market they operate. Users trust amazon.fr more than amazon.com/fr/ in France.
Best for: Large enterprises with unlimited budget and market-specific operations.
📖 Apple: Subdomain Strategy
Structure: apple.com (US), apple.com/fr/ (France - wait, they use subdirectory!)
Update: Apple actually switched FROM subdomains TO subdirectories in 2014. They initially used fr.apple.com, de.apple.com but migrated to apple.com/fr/, apple.com/de/.
Why they switched: Subdirectory allowed them to consolidate domain authority and simplified management.
Lesson: Even tech giants prefer subdirectory for unified global presence.
📖 Airbnb: Subdirectory Strategy
Structure: airbnb.com/en/, airbnb.com/fr/, airbnb.com/de/
Why: Rapid international scaling to 220+ countries. Subdirectory allowed them to leverage existing domain authority and launch new markets in weeks, not months.
Results: Dominates search in markets worldwide despite .com domain. Scaled faster than competitors using ccTLD.
Best for: Startups and tech companies prioritizing speed and SEO efficiency.
