How can I add Schema Aggregate Rating values?

Question

Accepted Answer

There are several ways to add aggregate rating markup to your content, but first, let&rsquo;s talk about what an &ldquo;aggregate rating&rdquo; actually is. ;-) The Schema.org website defines the Schema aggregateRating property value as: The overall rating, based on a collection of reviews or ratings, of the item. Two things to keep in mind about this: An aggregate rating value is calculated from several customer ratings / reviews for the current webpage content (e-commerce product reviews, for example). Google prefers &mdash; and often double-checks &mdash; that Schema markup reflects the current content of the webpage. So, if you want to manually set aggregate rating and/or review values in your Schema markup, make sure these customer ratings and/or reviews also appear in your webpage content (ie. the ratings and reviews are visible). So what&rsquo;s the best and easiest way? The very best (and easiest) way is to use a supported plugin that offers rating and review features, like the WPSSO Ratings and Reviews add-on. The WPSSO RAR add-on extends the WordPress comment system with optional rating and review features, and does not conflict with WooCommerce&rsquo;s own product rating features. ;-) Note that if you&rsquo;re using the WPSSO Core Pro plugin, ratings and reviews from WooCommerce, Yotpo Social Reviews for WooCommerce, and WP-PostRatings are also supported. Alternatively, if you&rsquo;re using a non-supported plugin &mdash; that saves aggregate rating values in post meta &mdash; you can use a WPSSO Core custom filter to add the Schema aggregateRating markup. Note that if you&rsquo;re using the WPSSO JSON Pro add-on, you can also hook the Schema aggregateRating property directly. Either filter will work fine &mdash; it just depends on your personal preference. ;-) If none of the above solutions work for you, the WPSSO Schema JSON-LD Markup add-on also offers a shortcode that you can use to customize the current webpage Schema properties. The schema shortcode documentation includes a practical example on how to add custom aggregate rating values to your content.
