Celebrity Endorsement Dynamics in Consumer Behavior

Celebrity endorsement remains a pivotal marketing strategy, leveraging public figures’ perceived attributes to shape consumer attitudes and drive purchasing decisions. Underpinned by theories of source credibility, source attractiveness and the match-up hypothesis, endorsements operate via affect transfer and cognitive elaboration to enhance brand recall, trust and favourability. Consumers often ascribe celebrity characteristics—expertise, likability or social capital—to endorsed products, which can catalyse herd behaviour and normative influence. Digital and social media platforms have magnified both reach and interactivity, enabling real-time engagement and rapid diffusion across global networks. However, effectiveness is contingent on congruence between celebrity persona and brand identity, and may be moderated by product involvement, consumer self-construal and exposure to publicised controversies. Practitioners must balance the potential for increased brand equity and willingness to pay a premium with risks such as negative spill-over or attenuated message recall. A nuanced understanding of these dynamics offers a foundation for evidence-based campaign design, optimising alignment between endorser attributes, media environments and target audiences to achieve sustained behavioural impact.
