The aim is to reach as wide an audience as possible, then encourage them to move down a funnel until at some point you might get some income. It's important to decide on your main channel, so that other sub-channels can be used to direct potential fans to it.
Look mum no computer uses YouTube as his main channel. Sam also posts on Instagram, Facebook and has a web site, all of which direct you to YouTube as well as doing their own thing. Sam's funnel probably goes like this.
- One of his videos may well show up on a casual YouTube viewer's feed, based on the mystery which is the YouTube algorithm. Alternatively one of your mates might share a link to a video they like.
- A subset of people watching this video will think "Who is this maniac? I love it!" and watch more of his videos.
- A subset of those will become subscribers.
- A subset of these will become engaged fans, comment on the videos and tell their mates.
- A subset of those fans will become Patreons (more on this layer).
There are other ways of getting your name out there, like Twitter, LinkedIn and a plethora of new sites like TikTok. Ultimately they all need to gently steer potential fans to your main channel, whatever that is.
