Online reviews are evaluations or feedback provided by customers about products, services, or experiences they have had. These reviews are typically posted on websites, social media platforms, or dedicated review sites, allowing potential buyers to read others' opinions before making a decision. They can include ratings, written comments, and sometimes photos. Businesses often use online reviews to gauge customer satisfaction and improve their offerings. Positive reviews can enhance a company's reputation and attract new customers, while negative reviews can highlight areas needing improvement. Overall, online reviews play a significant role in shaping consumer behavior and influencing purchasing decisions.
