Social media marketing has become essential for businesses of all sectors and sizes in the current digital world. However, many organizations encounter difficulties in promotion during their transformation. Thus, this chapter explores the possible problems affecting organizational performance in social media marketing using a case study of the University of Hong Kong Foundation under the lens of integrating the 5Es Usability Model (Effective, Efficient, Engaging, Error Torrelance, and Easy to Learn) and AIDA Marketing Communication Model (Awareness, Interest, Desire, and Action) models into a comprehensive framework. In the post-pandemic era, the reliance on digital marketing has intensified, making social media an even more pivotal tool for engagement. Furthermore, integrating Artificial Intelligence (AI) into social media marketing strategies has introduced new dynamics, offering predictive analytics, personalized content, and real-time engagement opportunities, which are critical for organizations like HKUF to stay competitive and relevant.
