单个页面上有多个 FAQPage 精选片段

Question

我们希望使用 JSON-LD 格式以FAQPage的形式添加特色片段。使用 Google 页面概述上的“查看标记”链接FAQPage，我们可以获得下面的示例特色片段。这似乎意味着该页面的所有问题都应该在一个<script>标签中。

我们通过Google 的结构化数据测试工具和丰富结果工具运行了以下内容，它返回了零错误。然而，没有提到它全部在一个script标签中。

问题

如果我们要使用FAQPage特色片段，我们需要使用的正确变体是什么（1 或 2）？

我们尝试了什么

变体 1 - 将所有问题集中在一个script标签中：

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": [{
    "@type": "Question",
    "name": "What is the return policy?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Most unopened items in new condition and returned within <strong>90 days</strong> will receive a refund or exchange. Some items have a modified return policy noted on the receipt or packing slip. Items that are opened or damaged or do not have a receipt may be denied a refund or exchange. Items purchased online or in-store may be returned to any store.<br /><p>Online purchases may be returned via a major parcel carrier. <a href='http://example.com/returns'> Click here </a> to initiate a return.</p>"
    }
  }, {
    "@type": "Question",
    "name": "Will I be charged sales tax for online orders?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text":"Local and State sales tax will be collected if your recipient's mailing address is in: <ul><li>Arizona</li><li>California</li><li>Colorado</li></ul>"}
    }]
  }
</script>

变体 2 - 每个问题都分为不同的script标签：

<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": {
    "@type": "Question",
    "name": "What is the return policy?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Most unopened items in new condition and returned within <strong>90 days</strong> will receive a refund or exchange. Some items have a modified return policy noted on the receipt or packing slip. Items that are opened or damaged or do not have a receipt may be denied a refund or exchange. Items purchased online or in-store may be returned to any store.<br /><p>Online purchases may be returned via a major parcel carrier. <a href='http://example.com/returns'> Click here </a> to initiate a return.</p>"
    }
  }
}
</script>
<script type="application/ld+json">
{
  "@context": "https://schema.org",
  "@type": "FAQPage",
  "mainEntity": {
    "@type": "Question",
    "name": "Will I be charged sales tax for online orders?",
    "acceptedAnswer": {
      "@type": "Answer",
      "text": "Local and State sales tax will be collected if your recipient's mailing address is in: <ul><li>Arizona</li><li>California</li><li>Colorado</li></ul>"
    }
  }
}
</script>

Answer 1

您可以使用任意script数量的元素，但您需要传达这些项目是相同的。您可以通过为它们提供相同的 URI（在 中）来完成此操作。FAQPage@id

\n\n

<script type="application/ld+json">\n{\n  "@context": "https://schema.org",\n  "@type": "FAQPage",\n  "@id": "/faq",\n  "mainEntity": {\n    "@type": "Question",\n    "name": "What is the return policy?"\n  }\n}\n</script>\n\n<script type="application/ld+json">\n{\n  "@context": "https://schema.org",\n  "@type": "FAQPage",\n  "@id": "/faq",\n  "mainEntity": {\n    "@type": "Question",\n    "name": "Will I be charged sales tax for online orders?"\n  }\n}\n</script>\n

\n\n\n\n

您可以只定义一次并引用每个问题（通过其） ，而不是FAQPage在每个元素中重复：script@id

\n\n

<script type="application/ld+json">\n{\n  "@context": "https://schema.org",\n  "@type": "FAQPage",\n  "@id": "/faq",\n  "mainEntity": [\n    {"@id": "/faq#1"},\n    {"@id": "/faq#2"}\n  ]\n}\n</script>\n\n<script type="application/ld+json">\n{\n  "@context": "https://schema.org",\n  "@type": "Question",\n  "@id": "/faq#1",\n  "name": "What is the return policy?"\n}\n</script>\n\n<script type="application/ld+json">\n{\n  "@context": "https://schema.org",\n  "@type": "Question",\n  "@id": "/faq#2",\n  "name": "Will I be charged sales tax for online orders?"\n}\n</script>\n

\n\n

mainEntityOfPage（如果您不想列出FAQPage.Google\xe2\x80\x99s 文档中的所有问题，那么您也许可以使用它。不过，另一种选择是使用@reverse。）

\n\n\n\n

您没有解释为什么要使用多个script元素。script如果您使用一个元素，但具有多个顶级项目（using@graph ） ，也许它适合您的情况。
