Audience Retention refers to the ability of content creators, such as YouTubers or streamers, to keep viewers engaged throughout their videos or streams. It is measured by the percentage of viewers who continue watching from the beginning to the end. High audience retention indicates that the content is interesting and relevant to the audience. Improving audience retention is crucial for success on platforms like YouTube, as it can influence search rankings and recommendations. Creators often use techniques like storytelling, engaging visuals, and interactive elements to maintain viewer interest and encourage them to stay until the end.
