Abstract

In the highly competitive luxury hospitality sector, it is essential to un-
derstand the factors that influence consumers’ intentions to visit. This

study purposes to examine the psychological internal relationships
among celebrity, consumer, and hotel brand. The study also explores

the effectiveness of social media influencers in determining consum-
ers ‘ intentions to visit luxury hotel brands. Brand personality theory

is employed to support personality congruency constructs. This study

utilizes the Stimulus-Organism-Response (SOR) model and social me-
dia influencers (SMIs) to theorize for the conceptual framework. Using

a quantitative research design, this research collects several 389 social
media users who actively engage with celebrity influencers endorsing
luxury hotels. The partial least squares structural equation modeling

(PLS-SEM) method is applied to evaluate the relationships among la-
tent variables with second-, and third-order constructs measurement

models. Psychological congruency demonstrates an essential role in

forming a robust construction between consumers, celebrities, and en-
dorsed luxury hotel brands. Consumers, who have an emotional at-
tachment to a hotel brand, tend to positively develop relations on social

media platforms, hence increasing the intentions to visit endorsed hotel

brands. This research advances the knowledge of psychological con-
gruency in the context of luxury branding and social media marketing,

creating an innovative strategy for the interaction between consumer
psychology and influencer endorsements. Practically, the explorations

deliver criminal recommendations for luxury hotel managers to opti-
mize their influencer marketing strategies.
