A review aggregate is a collection of different reviews and ratings for a particular product, service, or experience. It typically compiles reviews from multiple sources and presents an overall average rating or score based on the collective feedback. Review aggregates can be helpful for consumers in quickly assessing the general consensus on a product or service before making a purchase decision. They can also provide a more comprehensive view of the quality and performance of a product by considering a variety of opinions and perspectives. Overall, review aggregates can be a valuable tool for consumers looking to make informed choices and avoid potential pitfalls.
