Turn one-off videos into a binge-worthy series. Map out your episodes and their connections.
Make sure to use a consistent thumbnail style and link every video in the series using Cards and End Screens.
A series encourages "Binge-Watching". When a viewer watches multiple videos from your channel in one sitting, the algorithm starts recommending your content to them everywhere. This is the fastest way to turn a casual viewer into a loyal subscriber.
At the end of Episode 1, tell the viewer exactly what they will learn in Episode 2. Give them a reason to click the next video immediately. This increases your channel's "Session Duration".
