Abstract: The purpose of this study is to examine the relative effects of travel social influencers (TSI)’ total number of follower and engagement level on consumers’ intention to travel to advertised destination and purchase the advertised product as well as their perceived credibility, expertise, and attractiveness. The results suggest that engagement becomes an important characteristic of TSI in determining the effectiveness of advertising messages delivered by them and their perceived attractiveness especially when consumers are skeptical about influencer messages. Meanwhile, TSIs’ total number of followers better predict the effectiveness of advertising messages delivered by them and their perceived expertise when consumers are not skeptical about influencer messages.
