html - 在 Google 搜索结果中显示文章评分

Question

我正在编写一个社区评价帖子的评论网站。我注意到 Google 可以获取此评级并将其显示在其搜索结果中。有谁知道这是如何实现的？

例如 IGN 等评论网站，在下面的屏幕截图中，他们表示他们的评论评分为 9.3/10。

我如何向 Google 表明我自己的评价等级？也许是某种自定义元标记或其他东西。

您可以使用 Span 类来做到这一点。检查谷歌的Structure Data guide for Review :

A review is someone's evaluation of something. We support reviews and ratings for a wide range of schema.org types, including businesses, products, and different creative works such as books or movies.

Google displays the following types of reviews in search results:

• Critic review: A snippet from a longer review article that a single editor has created, curated, or compiled for a publisher.

• Review snippets: A rich result (previously known as a rich snippet) of a review or rating markup from a review website, usually an average of the combined rating scores from reviewers. Review snippets appear in Google Search results either under the search result or in the Google Knowledge Cards.

Here's an example of an aggregate rating.

<div itemscope itemtype="http://schema.org/Book">
  <h2 itemprop="name"> Super Book </h2>
  <div itemprop="description">Ultra interesting. Super impressive.</div>
  <div itemprop="aggregateRating" itemscope itemtype="http://schema.org/AggregateRating">
    <div>Book rating:
      <span itemprop="ratingValue">88</span> out of 
      <span itemprop="bestRating">100</span> with
      <span itemprop="ratingCount">20</span> ratings
    </div>
  </div>
