Research on the Impact of Big Data and Short Video Social Marketing on Consumers’ Decision-Making Psychology

This article explores the impact of big data and short-video social marketing on consumers’ decision-making psychology. Research shows that big data uses algorithmic analysis to precisely push content, while short videos enhance user engagement through their interactive nature and emotional resonance. The combination of precise content delivery and deep interaction can rapidly shorten the communication gap between brands and consumers. The two work together at the levels of consumers’ cognition, emotions, and behaviors, reshaping the path through which consumers receive information and also altering the internal logic of their preference formation and purchase decisions. The article not only analyzes the methods of collecting consumer behavior data and their practical applications but also explains the design logic of personalized recommendation systems. At the same time, it points out problems such as the information cocoon that may be caused by algorithmic recommendations, and it provides a thought-provoking starting point for balancing the application of technology and the protection of user rights and interests. The purpose of this research is to provide a reference for optimizing digital marketing models and helping consumers make rational decisions.
