Technological advancements in Indonesia have been on the rise, and the advent of technology has brought about significant changes in various aspects of society. The integration of technology into human life has greatly enhanced various activities, making information exchange and communication more accessible. As we observe the continuous evolution of technology, it has created new business prospects for companies to harness the power of the internet in providing online shopping services that connect consumers, service providers, and intermediary traders. E-commerce has emerged as a vital platform supporting commercial transactions via the internet. Prior to making a purchase, consumers frequently turn to social media for product reviews, where electronic word of mouth enables users to share their product-buying experiences. This study seeks to investigate the impact of user-generated information through electronic word of mouth on purchase intentions within the e-commerce landscape of Indonesia, utilizing the Information Acceptance Model (IACM). Employing a causal descriptive research approach, this study targeted e-commerce users in Indonesia, with 155 respondents participating. Data collection was carried out through Google Forms, and the collected data was analyzed using SmartPLS 3. Hypothetical testing included t-tests, p-tests, and path coefficient assessments. The study's findings revealed that variables such as information quantity, information needs, attitudes toward information, information usability, and information adoption all play a significant role in influencing purchase intentions, while information quality and information credibility had no discernible impact on purchase intentions.
