Treerating is a customer review and rating service for ecommerce businesses that wants to automatically collect reviews from their customers.
This is an integration between WordPress WooCommerce and Treerating services that automatically sends new customer’s data to Treerating’s API. The module also offers a Widget in the Appearance -> Widget section where you can present your aggregated rating from Treerating in your sidebar on your own website.
The plugin’s widget is using proper Rich Snippets following Schema.org standards, which allows Google to collect your rating and present it in the SERP (Search Engine Result Page), which has been proven to improve click through rates by magnitudes.
