Online reviews are a form of user-generated content that allow customers to share their opinions and experiences with products, services, businesses, or other entities on the internet. These reviews can be found on websites, forums, social media platforms, and other online platforms. They are often used by consumers to make informed purchasing decisions and by businesses to monitor and improve their reputation and customer satisfaction. Researchers in this area often study the impact of online reviews on consumer behavior, the credibility and reliability of online reviews, as well as the strategies businesses can use to manage and respond to reviews effectively.
