Don’t Like Them but Take What They Said: The Effectiveness of Virtual Influencers in Public Service Announcements

Despite the growing use of virtual influencers in communicating public service announcements (PSAs), their PSA communication effectiveness remains underexplored. Virtual influencers are digital entities who generate content on social media to establish a digital identity and personal brand. This research examines the effectiveness of virtual (vs. human) influencers in conveying PSAs, focusing on consumers’ attitudes toward the influencers and their acceptance of PSA messages. Three experimental studies (N = 1429) spanning different cultural contexts reveal that consumers hold a less favorable attitude toward virtual (vs. human) influencers who post PSAs. Nevertheless, virtual influencers are equally effective as human influencers in influencing consumers’ acceptance of PSA messages. Dual-mediation processes involving mind perception and novelty perception are identified. Furthermore, we find that incorporating emotional appeal can enhance the effectiveness of virtual (vs. human) influencers’ PSA communications. These findings contribute to the literature on virtual influencer marketing and PSA marketing, offering practical insights for leveraging virtual influencers in PSA campaigns.
