The growing adoption of online platforms for educational goals has raised concerns among learners regarding online learning contexts. These platforms have been identified as productive mediums for learning English as a second language. However, learners consistently strive for enhanced platforms, and their perspectives may change when confronted with concerns about the platform's overall quality, specifically in relation to its reliability and privacy. Therefore, this study aims to evaluate the impact of platform quality, including features such as reliability, design, and security, in combination with learners' familiarity with these platforms. A quantitative research approach was utilized to accomplish this goal, which entailed circulating an online survey by 410 Chinese North East public and private university graduate and postgraduate students, which were analyzed using SmartPLS 4 software. The study's findings indicate that certain elements of website quality, such as design and privacy, do not significantly impact platform satisfaction. Learners generally prefer criteria other than design and privacy considerations when assessing language learning applications. While platform design, familiarity and satisfaction significantly impact intrinsic motivation towards English learning. These characteristics contribute to the creation of a conducive learning environment for learners, which in turn promotes motivation, engagement, and, eventually, the development of language competency. By implementing these strategies, managers can cultivate a more immersive, gratifying, and stimulating English language acquisition encounter on online platforms, resulting in heightened satisfaction and competence. Based on the study's findings, the study suggested platform executives investigate these indicators using learner feedback and appropriately modify the platform's services.
