YouTube & FB Watch Recommendations
YouTube and Facebook Watch have their algorithms working to keep the viewer in the platform for as long as possible. This means that they serve the users content that is relevant and has a high potential to get clicked and watched. Among the factors are the themes the user is engaging with, currently viral videos, video’s engagement, etc. If the users who watch a video first are engaged and positive about it, it’ll be shown to more and if that still works–the reach will get even bigger.
This is how Squatty Potty commercial had so much organic growth. The video was golden, and the algorithms liked it and served it to new users–even though there was a paid campaign on it. And over 70% watched it end to end, for over 3 minutes!
