This study examines the strategic marketing of community-based sustainable tourism using a three-phase framework: elementary, intermediary, and industry. Focusing on CV Buniayu Triartha in Sukabumi, Indonesia, a qualitative descriptive method and PEST analysis were used to evaluate how political, economic, social, and technological factors shape community-based tourism marketing. Findings reveal that while community involvement and digital engagement enhance local impacts, challenges remain in institutional partnerships and technological infrastructure. A conceptual model is proposed to align local participation with sustainable marketing, offering practical recommendations for digital transformation and professional training.
