The development of short advertising videos has become a popular strategy for businesses in their operations, especially when the content of these short advertising videos primarily targets young user groups. This demonstrates the necessity of focusing research on analyzing the impact of short advertising videos on Facebook on the purchase intentions of the young user group. The aim of this study was achieved through the use of both qualitative and quantitative research methods, with data collected from 257 randomly selected college students from 5 private universities, representing young users. The analysis results showed that purchase intentions are influenced by 4 factors, with (1) Usefulness being the most impactful, followed by (2) Promotion, (3) Entertainment, and the least influential being (4) Interactivty. This study not only contributes to academic research but also assists businesses in effectively leveraging the potential of advertising videos on Facebook.
