What is the primary goal of utilizing end-screen promotions on YouTube?

The primary goal of end-screen promotions is to keep viewers engaged within your channel's ecosystem. By offering clickable links to other videos, playlists, or even a subscribe button, end screens encourage continued viewing and channel interaction, thereby increasing watch time and subscriber growth. This strategy leverages existing viewer interest to extend their session on your content. While end screens can include external links, that's not their primary purpose; YouTube prioritizes keeping users on its platform. Increasing advertising revenue is a byproduct of increased watch time, not the direct goal of the end screen itself. Prompting social shares is also a secondary benefit, as the core function is internal channel navigation and retention.
