Tapping the heart icon during a TikTok live broadcast registers approval of the content. This action signals to the algorithm that the viewer is engaged with the stream. For instance, if a user frequently “likes” content from a specific creator during their live sessions, that user is more likely to see future live broadcasts and videos from that creator in their “For You” feed.
The function serves several purposes. Firstly, it allows viewers to provide immediate feedback to the content creator, indicating they appreciate the live broadcast. Secondly, aggregated “likes” contribute to the overall visibility of the live stream within the TikTok platform, potentially increasing its reach to a broader audience. The act of registering approval has existed since the inception of live streaming functionality across multiple social media platforms, serving as a basic form of user interaction and content endorsement.
