TikTok has evolved from a simple dance app into one of the most powerful tools in brand marketing, reshaping the way companies communicate with their audiences.  This study examines how Duolingo and Ryanair use a humorous and playful tone on TikTok as a marketing strategy to strengthen their brand image and foster a closer connection with their target audience. It is based on a qualitative content analysis of three viral posts from each company, along with three comments per post. To explore how humor is employed to drive engagement and build audience closeness, each post was analyzed for visual and auditory elements, tone, and user interaction metrics such as views, likes and comments. These findings reveal that both brands have effectively adapted their content to TikTok`s unique logic through visual personification, pop culture references, and humor. High levels of audience interaction – reflected in likes and humorous comments – confirm strong engagement. This study contributes to a broader understanding of how brands can leverage humor on social platforms to enhance audience connection, amplify brand image, and navigate the potential risks associated with this strategy.
