End screens can help you build your viewership because they appear on both mobile and
desktop devices (iOS and Android), and can be used to:
- Get your viewers to check out other videos, playlists, or channels
- Ask your viewers to subscribe to your channel
- Send traffic to an approved website
- Offer merch
- Get fans involved in a crowdfunding campaign
You can add up to four end screens during
the last 20 seconds of your video, and each element can expand to show more info when you hover over (on desktop) or tap (on phones and tablets).
In the image I posted above you can see three different end screens appear at once. I took that screenshot just to show a few options,
but I wouldn’t recommend displaying more than one at a time because they’ll compete with one another for your viewer’s attention.
