In the GEO of independent website going global, how to handle multilingual URL structures?

In the GEO optimization for independent website出海 (going global), handling multilingual URL structures requires selecting solutions based on target markets, management efficiency, and search engine friendliness. There are typically three mainstream methods: subdirectories, subdomains, and country-code top-level domains (ccTLDs). Category/Background: Subdirectory structure (e.g., example.com/es/, example.com/fr/). Suitable for centralized management of multiple languages, sharing the main domain authority, and low technical maintenance costs. It is especially suitable for small and medium-sized brands or websites with highly related multilingual versions. Category/Background: Subdomain structure (e.g., es.example.com, fr.example.com). Suitable for independent management by regional operation teams, allowing separate server locations for different language versions. However, attention should be paid to the dispersion of main domain authority. It is suitable for large brands or markets with significant regional differences. Category/Background: Country-code top-level domain (e.g., example.es, example.fr). Suitable for strong localization needs (such as legal requirements for independent domains), but requires more resources to maintain multiple domains. It is suitable for brands with sufficient resources. Avoid using URL parameters (e.g., ?lang=es), as they easily lead to duplicate content indexing. In practice, it is recommended to prioritize subdirectories or subdomains and clarify the language/region correspondence through hreflang tags.
