Abstract The rapid advancement of digital marketing technologies, including artificial intelligence (AI), augmented reality (AR), and evolving social media platforms, has fundamentally transformed consumer engagement and marketing strategies. This systematic review explores these emerging technologies, focusing on their functionalities, applications, and impacts on consumer behaviour. AI-driven personalization enhances marketing efforts through predictive analytics, chatbots, and recommendation systems, resulting in improved engagement and conversion rates. AR provides immersive and interactive experiences, enabling consumers to visualize and interact with products in a virtual environment. Meanwhile, social media innovations, such as live streaming and interactive content, facilitate real-time engagement and foster brand loyalty. By synthesizing findings from recent studies, this review underscores the significance of integrating these technologies into digital marketing strategies to optimize consumer interactions and drive business success. Practical implications and recommendations for leveraging these advancements are also discussed, alongside limitations and areas for future research.
