Setting goals for your channel and understanding what you want to achieve by having a channel, is the first step to success on YouTube.
By having clear goals, you can ensure your channel uploads remain consistent and focused. Having consistent content helps retain subscribers as they are being delivered content which they initially subscribed for.
Is your channel to be used just to showcase your labels music, music for a particular artist, events you may be running, gear / music reviews etc, tutorials, or does your brand include multiple aspects which you want to showcase on your channel.
Having these goals in place also allows you to be focused on creating the content, you know exactly what type of content you need to create, and you can incorporate this into your workflow of running a label. For example, if you are in the studio with a guest producer, do a short interview.
