Marketplaces Explained: Review System

A review system is an evaluation procedure where consumers can rate services or products in a marketplace to provide feedback. The primary purpose of a review system is to promote transparency and trust in a business, ultimately leading to more informed decision-making by potential customers. It's an integral part of e-commerce platforms such as Amazon, eBay, and Etsy, but is also prevalent in service-oriented industries such as the hospitality and food sectors, with platforms like TripAdvisor and Yelp.


The review system typically functions by allowing users to provide ratings on a numeric scale – usually a one to five or one to ten basis. Along with the rating, customers can often leave written reviews detailing their experience with the product or service. These reviews, coupled with overall rating averages, give a broader snapshot of the marketplace's quality and reliability. Also, some review systems may include features like a verified purchase indicator or the ability to respond to reviews, giving companies the chance to rectify any negative experiences.

How it Works

The review system functions as a form of social proof, influencing potential customers' purchasing choices. For example, consider an online bookshop. A visitor is far more likely to purchase a book with multiple four-and-five-star ratings and positive user experiences than one with mediocre evaluations or none. The review system acts as a proxy for quality assurance, a testament to a product’s value from those who have previously availed of it.

The effectiveness of a review system doesn't stop at influencing buying decisions; it also offers companies opportunities to improve their products or services based on customer feedback. For example, a negative review highlighting a faulty product issue allows the business to acknowledge, rectify, and possibly prevent similar instances in the future.

In essence, the review system creates a feedback loop, fostering an environment of continuous improvement, coupled with promoting consumer trust and enhancing the overall marketplace experience.

Example Use

One of the most recognized review systems is on Amazon, the largest online retailer in the world. They have a comprehensive and efficient review system where buyers rate their purchases on a five-point scale, and provide feedback on the quality, delivery, and the overall experience.

This system has arguably been a critical contributor to Amazon's success, as potential buyers heavily rely on these reviews before making a purchase. The transparency and detailed insights have helped Amazon build trust among its users, ultimately leading to repeat purchases and a loyal customer base.
