html - 关于 'Question' 类型 : "Missing a QAPage markup item on page to which this item should be associated." 的警告

Question

以下Answer schema 在 Google 的 SDTT 中给出警告:

Missing a QAPage markup item on page to which this item should be associated.

微数据:

<div itemscope itemtype="http://schema.org/Question">
    <h1 itemprop="name">What is attr_accessor in Ruby?</h1>
    <div itemprop="upvoteCount">196</div>
    <div itemprop="text">I am having difficulty understanding Ruby attr_accessors, can someone explain them?</div>
    <div>asked <time itemprop="dateCreated" datetime="2010-11-04T20:07Z">Nov 11 '10 at 20:07</time></div>
    <div itemprop="author" itemscope itemtype="http://schema.org/Person">
        <span itemprop="name">someuser</span>
    </div>
    <div><span itemprop="answerCount">4</span> answers</div>
    <div itemprop="suggestedAnswer acceptedAnswer" itemscope itemtype="http://schema.org/Answer">
        <div itemprop="upvoteCount">1337</div>
        <div itemprop="text">
        (The text of the accepted answer goes here...).
        </div>
        <div>answered <time itemprop="dateCreated" datetime="2010-12-01T22:01Z">Dec 1 '10 at 22:01</time></div>
        <div itemprop="author" itemscope itemtype="http://schema.org/Person"><span itemprop="name">anotheruser</span></div>
   </div>
   <div itemprop="suggestedAnswer" itemscope itemtype="http://schema.org/Answer">
       <div itemprop="upvoteCount">39</div>
       <div itemprop="text">
      (Another explanation would go here).
   </div>
   <div>answered <time itemprop="dateCreated" datetime="2010-12-06T21:11Z">Dec 6 '10 at 21:11</time></div>
   <div itemprop="author" itemscope itemtype="http://schema.org/Person"><span itemprop="name">lonelyuser1234</span></div>
   </div>
</div>

此时此标记不适用于 Google 吗？

Answer 1

正如警告所说，Google 建议提供 QAPage项，可能符合 Google 的一项搜索结果功能。

您可以通过 mainEntity 将您的Question 关联到QAPage属性:

<div itemscope itemtype="http://schema.org/QAPage">
  <div itemprop="mainEntity" itemscope itemtype="http://schema.org/Question">
    <!-- … -->
  </div>
</div>
