The influence of social media celebrity endorsement on beer and wine purchase behaviour

Abstract

PurposeCelebrity endorsement is one of the most popular marketing communication tools that have been used by beverage companies to influence consumers’ behaviour, but little is known about the extent this communication strategy can be impactful and benefit alcoholic beverages like beer and wine. In this context, this study aims to examine whether and how social media celebrity endorsement influences consumers’ beer and wine purchase behaviour. Further, this study examines what are the characteristics of the celebrities that exert greater influence on beer and wine purchase behaviour.Design/methodology/approachBased on the source credibility and source attractiveness theoretical models, and on the match-up theory, a model of consumer purchase behaviour was proposed. Online celebrity endorsement was categorised as promoting either beer or wine, as well as beer and wine brands. Then, this model is empirically analysed through multiple group structural equation modelling on two samples of consumers who read online celebrity’s recommendations in Spain (beer = 280; wine = 277).FindingsFindings indicate that celebrity’s recommendations exert a different influence pattern on consumer purchase behaviour depending on the product category: congruence is the most relevant variable in beer endorsement, whereas expertise is the most influencing factor in wine celebrity recommendations. Therefore, beer celebrity endorsers should be congruent with the product, whereas wine endorsers should be perceived as experts.Originality/valueThis study extends the literature on celebrity endorsement providing an empirical examination of the social media celebrity characteristics that influence consumer purchase behaviour of beer and wine, reporting interesting differences between these two alcoholic beverages.
