Although celebrity endorsements and promotional videos dominated by destination marketing organizations (DMOs) are critical in travel decision-making and destination marketing, as a new type of endorsement, the impact of internet celebrities’ short travel videos on social platforms remains not well understood. To bridge this gap, the current study applied source credibility theory and the match-up hypothesis to construct a conceptual model for examining the impact of internet celebrity endorsements on audiences’ visit intentions. FangQi Kiki, a typical producer of short travel videos on TikTok, was used as a case study. 649 valid samples were taken from respondents who were asked to complete a questionnaire after watching a short video. The results showed that internet celebrities’ trustworthiness and expertise significantly affect audiences’ visit intentions. However, attractiveness in terms of the physical characteristics of internet celebrities and internet celebrity–destination congruence had no significant effect on audiences’ visit intentions. The implications show that “Appearance Fallacy” exists in online influencers’ marketing, and physical appearance may affect the popularity of short travel videos online, but it has no significant effect on promoting destination marketing. Unlike the celebrity effect in conventional endorsements, internet celebrities’ short videos belong to content marketing, where popular content is more important than an internet celebrity’s personality. This research adds to the body of knowledge concerned with internet celebrity endorsements in tourism, providing valuable insights for DMOs to project short video marketing.
