If you’ve ever wanted to offer a rating out of 5 stars for a product or service or website or movie or really whatever you’re blogging about, then this is the plugin for you. I went looking for something that would do exactly what I wanted, but couldn’t find it ? and I didn’t want a new theme that incorporated rating functionality.
You decide which features to rate on a site-wide basis. For example, a movie rating site might want to include features like: plot, characters, quality etc. Where an app reviewer may want to have features like: price, playalbility, value etc. I have plans for a future version that would allow changing the features on a per-post bvasis.
Please let me know if you have any problems with the plugin or have any suggestions for future updates.
<h3>To do</h3>
<ol>
<li>Allow changes to rated features on a per-post basis</li>
<li>Allow the exclusion of one or more rated features</li>
</ol>

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>
