With the development of social media, most people will use social media to watch the videos of digital influencers to get spiritual comfort, and they will think that digital influencers are like friends who are connected with their own lives. However, most of the previous studies focused on the influence of digital influencers on followers’ behavioral intentions (e.g. loyalty, and purchase intention). They rarely discussed the online social well-being obtained by followers after watching digital influencers' posts. Therefore, this study integrates the attributes of followers (loneliness, low self-esteem, empathy) and the characteristics of digital influencers (social attractiveness, expertise, homophily) to explore the influence of the parasocial interaction established between digital influencers and followers on followers’ online social well-being. This study uses the Internet to collect questionnaires and takes users who have watched digital influencers' posts on social media as the research object. A total of 597 valid questionnaires are collected. The research results show that: the characteristics of digital influencers (social attractiveness, expertise, and homophily), and followers' attributes (low self-esteem and empathy) have positively affected parasocial interaction. It is noteworthy that loneliness has no significant effect on parasocial interaction.

Influencer marketing for the past decade has proven to have a powerful voice for brands in the age of digital marketing. The role of influencer(s) continues to have the ability to motivate social attitudes and behavior within their online community towards the brand(s) endorsed by the influencer. The communities built by these social media influencers continue to gain social acceptance with their authentic voices and aspirational content. There has been much research on the effectiveness of social media influencers for brands the past decade, and in this research, we will look towards virtual influencers (VIs), which are not human but are digital recreations with levels of human likeness. In our study, we want to get a better understanding of whether VIs are capable of achieving comparable success to the traditional influencer, as well as the advantages and shortcomings of both types of influencers hold.
