The influence of celebrity endorsement on the purchase behavior of brands and product categories

Purpose Celebrity endorsement has been profusely used to promote the consumption and purchase intention of diverse product categories; however, there is scarce research about whether celebrity endorsement effectiveness differs between brands and product categories. In this context, this study aims to answer this question: “Does consumer purchase behavior influenced by celebrity endorsement differ between brands and products?”. Design/methodology/approach To this end, a conceptual model of the influence of celebrity endorsement on consumer purchase behavior is examined through a multiple group structural equation modeling on two consumer samples (315 = brands; 308 = product categories). Samples were categorized as a celebrity promoting either a product category or a brand, and food products were selected as the product category for the investigation. Findings Findings indicate differences in the effectiveness of celebrity endorsement between brands and product categories: credibility is the most relevant variable influencing consumer purchase intention for product categories, while credibility and congruence both influence consumer purchase intention for brands. Similarly, the celebrity recommendation of brands generates greater purchase intention due to celebrity congruence with the endorsed product. Originality/value To the best of the authors’ knowledge, the present research is one of the first endeavors to compare the effectiveness of celebrity brand endorsement versus celebrity product endorsement on purchase intention.
