问题:

Im writing a review site where the community rates posts. I have noticed that Google can pick up on this ratings and display them in its search results. Does anyone know how this is achieved?

An example is a review site like IGN, where in their screen shot below they have indicated their review has a rating of 9.3/10.

How can I indicate to Google my own review rating? Maybe some sort of custom meta tag or something.

You can do that with a Span class. Check Google's 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>
