This study aims to analyze the influence of the number of endorsers and the product’s involvement on the consumers’ attitude towards the advertisement and the brand. The research’s approach used a 2x2 factorial experimental design. A total of 120 undergraduate students, who were further divided into 4 groups, were selected as the respondents of this study. The results show the differences in consumer attitudes towards advertisements and the brand, based on the number of endorsers and the product’s involvement. The study also reveals that if there is low involvement with the product, multiple celebrity endorsements will generate a better consumers’ attitude towards it than a single celebrity endorsement. Multiple celebrity endorsements will also generate a better attitude among the consumers towards the brand than a single celebrity endorsement will produce Keywords: attitude towards advertisement; attitude towards brand; experimental design; multiple celebrity endorsers; product involvement Sources: https://jurnal.ugm.ac.id/gamaijb/article/view/18338/19307
