YouTube Short
Whether the video is a YouTube Short — a vertical video under 60 seconds. Shorts are distributed through a completely separate algorithmic feed from regular videos.
YouTube Shorts reach a different audience through a different algorithm. They can dramatically increase impressions and subscriber growth, but Shorts viewers are less likely to convert into regular video watchers. Shorts also have different engagement patterns — views are high but watch time per view is inherently capped.
Average Video is the effect on a typical video. Top 10% Video is the effect on the videos that broke out (top decile of views) — so you can see whether a factor helps most videos a little, or pushes the top performers much higher.
