Interactive features are built-in platform tools that enable creators to engage their audience directly within or alongside video content. On YouTube, interactive features include end screens, cards, polls, chapters, pinned comments, Super Chats during live streaming, and community posts. These features encourage active viewer participation rather than passive consumption, which strengthens engagement signals and can improve viewer retention. Effective use of interactive features supports both genuine engagement and channel growth by turning one-way viewing into two-way audience interaction.
