Online reviews significantly influence tech product success by shaping consumer perceptions and purchasing decisions. Positive reviews can enhance a product's credibility, leading to increased sales, while negative reviews can deter potential customers. They serve as a form of social proof, where prospective buyers rely on the experiences of others to assess the product’s quality and functionality. Brands also leverage online reviews to gather feedback, improve their offerings, and foster a loyal customer base. Thus, the volume and sentiment of online reviews can directly impact a product's market performance.
