Online reviews influence consumer trust significantly as they provide social proof of a product or service's quality. Positive reviews can enhance a brand's reputation, encouraging potential customers to engage with the business. In contrast, negative feedback can deter purchases and harm a company's image. Ratings and reviews on platforms like Google and Yelp are often seen as more credible than traditional advertising, as they reflect real-user experiences. Consequently, businesses should actively manage their online reputation, responding to feedback and addressing concerns to maintain consumer trust and loyalty.
