The findings indicate that product quality and promotion have a positive and significant effect on consumer purchase decisions, both individually and simultaneously. In conclusion, product quality plays a critical role in shaping consumer perceptions and trust toward the product, while promotional activities contribute to increasing consumer awareness and purchase intention in the digital marketplace environment. These results highlight the importance of maintaining product quality and implementing effective promotional strategies to enhance consumer purchasing decisions.
