Outliers matter most when you find them on channels similar in size to yours. A big channel outperforming is normal; a channel like yours suddenly doing five times its usual numbers is a topic worth studying.
What is an outlier video on YouTube?
An outlier is a video that scored several times more views than the average video on the same channel. It signals that the topic itself hit real viewer demand, not that the channel suddenly got lucky.
