Short answer

Ratings and reviews are customer star scores and written feedback displayed on product pages. They give shoppers social proof about quality and fit, and are among the strongest drivers of ecommerce conversion. Many marketplaces also factor review volume and rating into search ranking, so brands actively work to generate and manage them.
