A review system is a structured process that allows users to evaluate and provide feedback on products, services, or experiences. This system often includes ratings, comments, and suggestions, helping potential customers make informed decisions. Review systems are commonly found on platforms like Amazon, Yelp, and TripAdvisor. These systems benefit businesses by highlighting strengths and areas for improvement. Positive reviews can enhance a company's reputation, while negative feedback can prompt necessary changes. Overall, a review system fosters transparency and accountability, encouraging better quality and customer satisfaction in various industries.
