With the development of mobile technology, individuals are increasingly sharing their own tourism-related videos on mobile platforms, a trend that has yet to be fully studied in terms of its impact on consumer behavior. Moreover, while existing research has examined the use of video platforms in the tourism industry, there is a lack of studies that explore the moderating effects of the existing city image on consumer behavior. Therefore, this study examines the marketing effectiveness of utilizing video platforms for tourism websites, with a focus on Chinese tourists. Specifically, this study focuses on the relationship between video information characteristics, satisfaction, and visit intention. Additionally this paper aims to address this gap by investigating how the existing city image affects the relationship between video information characteristics, satisfaction, and visit intention. The findings of this study will provide valuable insights for tourism marketers seeking to use video platforms as a means of promoting tourist sites.
