Expanded product specs
Create a tell-all rating system for each product/service you offer and let users rate them by the pre-defined criteria.

Visible average stats
Decompose any given post type to bring its essentials into focus: total reviews, both review’s and post’s average ratings, as well as all reviews’ ranking.

Multiple rating scales
Stick to a rating system you prefer and display user reviews as stars, points, or percent.

Streamlined voting
Bring Likes/Dislikes into play to urge C2C interactions and leverage social proof.
