II. The Development History and Strategy Evolution of Multilingual Website Construction

The history of building multilingual websites is an evolution from "extensive translation" to "refined Hreflang architecture".

1. Early Stage: Human Translation and Domain Name Experimentation (2000s-2010)

• Technical features: It mainly relies on human translation and uses different domain name structures to distinguish languages.

  • Independent domain name (Country-code TLD): such as example.de, example.fr.

  • Subdomains: such as https://www.google.com/search?q=en.example.com, https://www.google.com/search?q=fr.example.com.

2. Google Hreflang Standardization and SEO Driven (2010-2018)

• Milestone: Google officially launched the Hreflang tag to identify different language or regional versions of a website .

• Technological shift: Multilingual website development is moving towards subdirectory structures ( example.com/en , example.com/fr ) and is mandated to deploy Hreflang .

• Challenges: Hreflang deployment is extremely complex , and code errors and content matching errors result in inconsistent website rankings for many websites . **Website performance (CWV)** is beginning to face challenges in global deployments.

• Key focus: The multilingual website system becomes a one-stop solution that natively supports Hreflang automation, AI-assisted content localization, and global CWV optimization .

  • The "x-default" tag: Deploy the "x-default" tag to instruct Google which default version to display when it cannot match the user's language or region .

  • Automated error diagnosis: A professional system monitors Google Search Console reports in real time . $100\%$ detection and fix of Hreflang deployment bugs**, avoiding potential ranking and indexing issues .

  • Cultural and habit adaptation: Adjust images, color schemes, date formats, currency, units of measurement , etc. $100\%$ compatible with the cultural habits of users in the target country**.

3. Global performance optimization and CWV compliance

• Principle: To ensure that website loading speed and user experience meet Google's Core Web Vitals (CWV) standards in any corner of the world .

• Core technologies:

  • Global CDN network deployment: Deploy the website's static resources to a global content delivery network (CDN) to ensure fast loading for users in Europe, Asia, South America, and other regions .

  • Server location optimization: Select server locations based on primary target markets to minimize latency .

  • Code simplification and asynchronous loading: Ensure that multi-language switching mechanisms, scripts, style sheets , etc. , do not hinder the loading of critical page content , passing CWV performance testing .
