This study examined the relationship between key emotional features of 60 online stories promoting 12 US cities and states and reader engagement as measured by average reading time. Sentiment analysis was used to analyze emotion levels at the beginning, peak, and end of each story, and multiple regression was performed. The results showed that emotion levels at the 20%, 30%, and 80% points of the stories significantly correlated with longer reading times, suggesting these emotional features increase reader involvement. The findings provide insights for designing more persuasive online stories to promote tourism destinations.
