Theoretical Framework: This topic is underpinned by several key concepts and theories. Häusel's Limbic Map, consumer behavior theories, and digital marketing frameworks provide a solid basis for understanding the context of the investigation. Method: The methodology adopted for this research comprises a quantitative approach using structural equation modelling with SmartPLS. Participants included 440 respondents, who were surveyed via Google Forms. The study analyzed variables such as Persona, User Interaction, Information Quality, Ease of Use, Visual Design, Entertainment Value, Customization, and Website Domain.
