很多出海企业疑惑：为什么网站有收录、有排名，却从来不会被 ChatGPT、Google SGE 推荐？核心原因是：大模型抓取逻辑和搜索引擎爬虫完全不同。

Traditional search engines crawl for "keyword density, backlinks, and authority"; large models crawl for "structured information, authoritative signals, citable answers, and entity trustworthiness."

海外大模型抓取企业官网，主要依赖 4 个核心信号：

**1. Standardized Structured Data (Schema)**

Large models prioritize pages with structured markup (Org, Service, FAQ, Article) to quickly identify the website's core entity, business scope, and service offerings. Sites without Schema are flagged by AI as "ambiguous information" and deemed unreliable.

**2. llms.txt AI Guidelines File**

2026 年主流 AI 爬虫（GPTBot、ClaudeBot、Google-Extended）会优先读取网站根目录 llms.txt，快速抓取企业核心简介、主营业务、服务范围、客户群体。

**3. 答案型内容结构**

AI 只引用"短句、清晰、结论前置、问答式"内容。长篇软文、营销文案、堆砌词汇的页面，不会被 AI 收录引用。

**4. E-E-A-T Authority Signals**

Case studies, industry certifications, client endorsements, team expertise, and original insights are the core criteria LLMs use to assess brand credibility.

Only when a corporate website meets all four criteria will it be added to the AI model knowledge base, enabling "AI-driven recommendations and citations."
