Product ratings are numerical or star-based evaluations that reflect customer satisfaction with a specific item. These ratings help potential buyers gauge the quality and performance of a product before making a purchase. They are often based on user reviews and can range from one star (poor) to five stars (excellent). Many online retailers, such as Amazon and eBay, display product ratings prominently to assist shoppers. Ratings can also include written feedback, providing insights into the experiences of previous customers. This information is valuable for consumers looking to make informed decisions and for companies aiming to improve their products.
