How to Make Your YouTube Channel Clickable for Non-Subscribers

I think in your particular case I'd be looking at the click-through rate for non-subscribers. A video that's under 10 minutes can't deliver more than 10 minutes of watch time. The thing is, all videos should be exactly as long as they have to be and absolutely no longer. So you might want to think about a way in which you have a longer video that generates more watch time but not at the expense of watchability or retention. It's going to show people the video that's going to keep them on YouTube for 15 minutes. And so my average watch time is roughly double the length of your entire video.
