Innovation in Interior Design Brand Marketing: The Integration Path of Social Media and Immersive Experience

Driven by digital technology, social media and immersive experiences (such as VR/AR and Metaverse) are reshaping the marketing model of interior design brands. Based on the theories of interactive marketing and sensory marketing, this paper constructs a "social + immersive" fusion framework and proposes a three-dimensional collaborative path: through dynamic interactive content (such as panoramic videos, AR real-time annotation), virtual and real fusion scenes (such as AR filters, Metaverse exhibition halls) and user co-creation mechanisms (such as gamification challenges and data-driven recommendations), it solves the high cost and static pain points of traditional marketing, and optimizes the low conversion rate of social media and the threshold of immersive technology. The study provides brands with a full-link strategy from traffic acquisition to user conversion, and points out that in the future, it is necessary to balance technological innovation and ethical risks and explore cutting-edge directions such as AI-generated content.
