Comment velocity
The rate of comments accumulated in the first hours after upload.
Comment velocity is a recognized input into YouTube's early ranking decisions.
It is driven by emotional valence, opinion polarity, and explicit calls for comment.
Channels that consistently produce high comment velocity earn additional recommendation signal.
