For most viewers, only your top section will be visible without scrolling — so make sure your most important videos are included in the section at the top of your channel page. Also, because sections can contain content from other channels, you have a great opportunity to cross-promote with other artists and curate an interesting viewing experience for your audience. To add a section, just click the “Add a Section” button from the bottom of your channel home page.
If you want to get more followers, it doesn’t hurt to let your viewers know that and to actively remind them to subscribe. We all know how powerful CTAs can be, and this is no exception. In addition to urging viewers to “Subscribe!” at the bottom of your description, you can add “Subscribe Now!” CTAs to the end of every YouTube video by adding YouTube elements to the last portion of it. Previously this could be done with annotations, but that feature has been deprecated. You can do this under the “End Screen & Annotations” tab when you’re editing your video.
