Average rating

Store the average customer rating for each of your products in a metafield and use it for product filtering in your admin or for logic purposes directly in your Liquid code. You can also trigger a workflow whenever your products' average rating change.

This is an expansion on the standard Shopify metafield reviews.rating which return your average review rating per product as a decimal number between 1 and 5. This use of this standard metafield is used by several review apps such as Judge.me, Shopify reviews etc.

Espresso mirrors the average rating from this metafield into another metafield designed specifically for admin filtering. The average rating is rounded to the nearest integer, giving an average rating between 1.0 and 5.0 in steps of 1.0. No reviews for a given product will yield an implicit rating of 0.0.

The calculated rating is assigned a label based on the value, as follows:

• 5 = 5 ★★★★★
• 4 = 4 ★★★★☆
• 3 = 3 ★★★☆☆
• 2 = 2 ★★☆☆☆
• 1 = 1 ★☆☆☆☆
• 0 = No rating

This approach gives you easy-to-use admin filter options to identify products based on their average review rating.
