What is the primary function of 'end screens' beyond promoting related content?

Beyond promoting related content, the primary function of 'end screens' is to convert viewers into subscribers, directly growing your channel's audience base. While end screens can promote other videos or playlists, their most crucial role is to provide a clear and direct call to action that prompts viewers to subscribe to your channel. A subscription element on the end screen offers a one-click option for viewers to join your community, increasing the likelihood of them becoming regular viewers. End screens can significantly impact subscriber growth as they appear at the end of a video when viewers are most engaged and have already invested their time in watching your content. This makes them more receptive to subscribing, as they have already experienced the value your channel offers. Optimizing end screens with a prominent subscription button and compelling visual cues can dramatically improve subscriber conversion rates. By strategically placing the subscription element alongside other relevant content suggestions, you maximize the chances of viewers continuing to engage with your channel and becoming loyal subscribers. End screens help solidify the viewer's decision to follow your channel, leading to long-term audience growth and sustained engagement.
