There actually is an outcome worse than a missed click: if too many viewers are abandoning your video within the first few minutes (i.e. before midrolls), you'll experience substantial downranking.

More or less, the art of making a successful video requires:

* An attention-grabbing thumbnail

* A curiosity-provoking title & premise

* A strong hook which convinces the viewer to put the screen down and let it run

* Editing which delivers the information at an engaging (yet monetizable) pace

* Packaging said information so that it is intelligibly balanced across the mediums (audio/text/video)

* ^^^ Doing this all in a style which still retains enough uniqueness to establish a repeat viewerbase

"The algorithm" is a system for efficiently delivering novel videos with these qualities to the audiences who will most eagerly consume them, which is an essential function for a platform with 2 billion monthly users. For every video on lowest-common-denominator celebrity junk, there's a dozen niche videos tailored to some ravenous subculture or other. Not all magazines are tabloids... but just about anyone can kill time with a tabloid, so that's what leads.

Unlike magazine stands, however, the platform will eventually learn to only show you the thumbnails for videos you'll want to finish watching. It's almost embarassing to share... but here's an example batch of 12 recommendations, almost all of which I'm likely to (eventually) click on and fully watch: https://i.imgur.com/dygfXXb.png
