Verdix Reviews

Review boxes with structured data (JSON-LD) for WordPress. Star ratings, pros/cons, and schema markup that Google understands.

JS Morisset

Includes a 5 Star Rating in Schema markup:
<ol>
<li>If the Schema markup does not have an ‘aggregateRating’ property.</li>
<li>If Google allows an ‘aggregateRating’ property for that Schema type.</li>
</ol>
Google allows an ‘aggregateRating’ property for these Schema types and their sub-types:
<ul>
<li>Book</li>
<li>Course</li>
<li>Event</li>
<li>HowTo (includes Recipe)</li>
<li>LocalBusiness</li>
<li>Movie</li>
<li>Product</li>
<li>SoftwareApplication</li>
</ul>
If the Schema type in the Document SSO metabox is not one of these types (or one of their sub-types), then a 5 star rating cannot be added, as doing so would trigger an error in the Google search console. <a href="https://developers.google.com/search/docs/advanced/structured-data/review-snippet" rel="nofollow ugc">See Google’s Review snippet documentation for additional information.</a>

<h3>WPSSO Add Five Stars is a Fallback Solution</h3>
The Google’s Review Snippet technical guidelines reminds us to:
<blockquote>
<a href="https://developers.google.com/search/docs/advanced/structured-data/review-snippet#technical-guidelines" rel="nofollow ugc">Make sure the reviews and ratings you mark up are readily available to users from the marked-up page. It must be immediately obvious to users that the page has review content.</a>
</blockquote>
The WPSSO Add Five Stars add-on includes a 5 star rating if the document Schema markup does not already have an ‘aggregateRating’ property. It is always preferable to include actual ratings and reviews from your visitors and/or customers in the webpage. The WPSSO Add Five Stars add-on can be used in combination with any of the following third-party plugins and service APIs, or the <a href="https://wordpress.org/plugins/wpsso-ratings-and-reviews/" rel="ugc">WPSSO Ratings and Reviews</a> add-on.
