YITH WooCommerce Advanced Reviews allows creating a more usable and easy to browse review section. This plugin will help you have complete management of reviews by choosing, for example, those to highlight or allowing users to filter them and view the most significant ones.
The integration between these two plugins allows sending a discount to customers posting a review of the purchased products by relying on YITH WooCommerce Advanced Reviews engine.
You will only need to install and activate both plugins and configure them separately.
For further details about YITH Advanced Reviews settings, please refer to the official documentation.
