多语言网站如何兼顾 SEO 与 GEOMultilingual: SEO + GEO
出海网站既要被谷歌、百度搜到，也要被海外 AI 引擎引用。关键在 hreflang、真本地化与权威信号三件事。A global site must rank in Google/Baidu and be cited by overseas AI. The keys: hreflang, real localization and authority signals.
1. hreflang 别配错1. Get hreflang right
每个语言版本用 <link rel="alternate" hreflang="…"> 互相标注，并指向 x-default。配错会导致重复内容或语言错投。Label each language version with <link rel="alternate" hreflang="…"> and point to x-default. Wrong config causes duplication or wrong-language serving.
2. 翻译 ≠ 本地化2. Translation ≠ localization
机器直译会被 AI 判为低质。要做术语、案例与表达方式的本地化，英文页面尤其要符合目标市场的搜索与提问习惯。Literal MT reads as low-quality to AI. Localize terms, cases and phrasing — English pages must match how the target market searches & asks.
3. 用权威外链建立信任3. Build trust with authority links
本地媒体、行业站点与目录的外链，是海外搜索与 AI 判断「这个站点可信」的重要依据。Links from local media, industry sites and directories are how overseas search & AI judge "this site is trustworthy".
4. 结构化数据带上语言4. Mark language in structured data
inLanguage 等字段帮助引擎理解每页语言，配合 FAQ、Article 等 schema 提升被抽取概率。Fields like inLanguage help engines understand each page's language; pair with FAQ/Article schema to raise extraction odds.
