多语言网站SEO策略：独立域名VS子目录的终极指南

Multilingual Website SEO Strategy: The Ultimate Guide to Separate Domains vs Subdirectories

随着全球化的推进，多语言网站已成为企业拓展国际市场的重要手段。在构建多语言网站时，企业面临着一个重要的决策：是使用独立域名还是子目录来展示不同语言的内容。

With the advancement of globalization, multilingual websites have become an important means for businesses to expand into international markets. When building a multilingual website, companies face a crucial decision: whether to use separate domains or subdirectories to display content in different languages.

一、子域名和子目录的核心区别

1. Key Differences Between Subdomains and Subdirectories

概念定义：
子域名是顶级域名的下一级（如en.example.com），而子目录是网站结构中的路径（如example.com/en/）。

Definition:
A subdomain is a subdivision of the main domain (e.g., en.example.com), while a subdirectory is a path within the website structure (e.g., example.com/en/).

SEO影响：
子域名会被搜索引擎视为独立网站，需要单独积累权重；子目录则继承主域权重，SEO效果更易传递。

SEO Impact:
Search engines treat subdomains as separate websites that need to build authority independently, while subdirectories inherit the main domain's authority, making SEO benefits easier to transfer.

二、独立域名策略的SEO分析
