Social media influencers are key actors shaping tourists’ attitudes and decisions, particularly regarding destination choice. This study applies the Information Adoption Model (IAM) to examine how TikTok content affects the perceived usefulness of information, its adoption, and visit intention. Using a quantitative approach with PLS-SEM and a sample of 360 users from Metropolitan Lima who follow travel influencers, the findings reveal that trustworthiness, expertise, argument quality, and information quality significantly influence perceived usefulness. In turn, perceived usefulness impacts information adoption and visit intention, with adoption emerging as the strongest predictor. The research validates the IAM in a short-form content environment and provides implications for digital tourism marketing, suggesting collaboration with trustworthy influencers and the creation of clear and relevant content.
