Brackets
Whether the title includes square brackets — usually wrapping a label like [BREAKING], [WATCH], [LIVE], or [UPDATE].
Bracketed labels are a news-style convention that signals urgency or category to the viewer scanning a feed. They read as editorial framing: 'this is important enough to label.' But they're rare — only ~84 videos use them — so any estimated effect is noisy and should be interpreted cautiously.
Average Video shows the effect on a typical video. Top 10% Video shows the effect on videos in the top 10% of views — estimated via quantile regression, so you can see whether a factor helps most videos a little, or pushes the top performers much higher.
