On TikTok, the “nudge” functionality, when incorporated into the repost feature, serves as a prompt or reminder to users. It aims to encourage individuals to share content they have previously engaged with on the platform. Functionally, this can appear as a notification suggesting a user share a video they recently liked or viewed, thereby broadening its reach. For example, a user might receive a notification stating, “Enjoyed this video? Repost it to share with your followers.”
This function is implemented to amplify content visibility and foster increased engagement within the TikTok ecosystem. The benefit of such a prompt lies in potentially boosting the views and reach of the original video, which can be particularly valuable for content creators seeking to expand their audience. Historically, platforms have implemented similar prompts in various forms to encourage content sharing and active user participation.
