By integrating Yotpo with Nosto you will be able to show rating and review count in your personalized product recommendations from Nosto on design-template level. Additionally you will be able to filter products based on rating and number of reviews. This can for example be used to make sure low rated items or items with just a few reviews are never are recommended by Nosto.
Once you've installed the Yotpo for Magento or Shopify extension, you'll need to follow their guide how to set up Rich Snippets. This differs a bit depending on your e-commerce platform, and you can find the guide for Magento 1 here, Magento 2 here and Shopify here.
After this step, Nosto begins collecting the rating and review metadata automatically. There is no additional configuration required on Nosto's end to set up the integration.
Enabling ratings and reviews in Nosto recommendations requires setting up and optionally designing recommendation templates to support ratings and reviews.

Using Default Templates
If you use default recommendation templates, simply flip the switches under Template Settings > Properties and disable or enable ratings and/or reviews
Using Custom Templates
If rich snippets have been set up correctly inside the template section the variables product.reviewCount and product.ratingValue are now available for use:
$!product.reviewCount = Number of reviews collected.
$!product.ratingValue = Rating. Value between 0.0 and 5.0.
Create the actual stars using CSS based on the variables above for example by following this article.
