Automatically add the rich snippets schema to display review stars on Google searches for WooCommerce Products.
It’s very simple.
When the product has reviews left by customers, it will automatically add this schema code:
<pre><code>{
 "@context": "http://schema.org",
 "@id": "#product",
 "@type": "IndividualProduct",
 "aggregateRating": {
 "@type": "AggregateRating",
 "ratingCount": "$rating_count",
 "ratingValue": "$average_rating"
 },
 "name": "$product_title",
 "category": "$category"
}
</code></pre>
… which makes Google display the review stars on the search pages.
No setup needed. Everything is automatic. Just activate the plugin. 
This plugin is super lightweight and it’s completely free.
