Google 富结果
FAQPage 标记明确告诉 Google 页面包含哪些问答对,使页面有资格展示 FAQ 富结果 — expandable Q&A directly inside search listings that increase your SERP real estate and click-through rate. Since 2023 Google shows these mostly for authoritative sites, but the markup still helps Google understand and rank your content, and Bing continues to render FAQ rich answers for many sites.
AI 问答引擎(ChatGPT、Perplexity)
Generative engines such as ChatGPT, Perplexity, Copilot and Google AI Overviews retrieve pages and quote the cleanest passages. JSON-LD gives their crawlers unambiguous, machine-readable Q&A pairs — which is exactly the format answer engines prefer to extract and cite。结构化 FAQ 是生成式引擎优化(GEO)的核心手段。
保持合规
只标记 页面上可见的,与内容使用相同语言,避免在回答中夹带广告,且每个 URL 只用一个 FAQPage 代码块。有效、准确的标记能同时赢得传统爬虫与 LLM 爬虫的信任。
