This paper investigates how cultural organizations can enhance digital audience engagement by understanding and addressing the underlying motivations for cultural consumption. Employing a dual-method research design, the study combines qualitative focus groups with Athenian cultural consumers and a content analysis of Onassis Stegi’s social media communication strategies. The analysis identifies six motivational audience profiles—Get Stimuli, Socialiser, Art Seeker, Entertainer, Fans, and Education Seeker—each representing distinct emotional, cognitive, and social drivers for cultural participation. The study further explores how persuasive digital communication techniques, including copywriting formulas such as AIDA, 4Cs, PAS, and the 4Us, as well as cliffhangers, edutainment, CTAs, and hashtags, align with these motivations to foster meaningful engagement. Findings indicate that content tailored to audience values enhances emotional resonance, encourages interaction, and supports sustained engagement. While Onassis Stegi demonstrates effective application of several frameworks, the research identifies opportunities for further strategic alignment, especially in targeting under-addressed profiles. The study offers actionable recommendations for arts organizations to improve digital content strategies through motivational alignment. More broadly, it proposes a practical framework for optimizing digital communication in the cultural sector and contributes to the ongoing discourse in arts marketing and audience development by emphasizing the value of audience-centered engagement in an increasingly digital cultural landscape.
