About viral niches

›How is a niche's viral rate measured?

Each niche's figure is the share of its tracked channels that published at least one video scoring 5x or more against their own channel's norm in the window. A niche ranks high because its creators break out often, not because it is big.

›What counts as long form here?

Videos over three minutes that aren't Shorts. Shorts are counted separately, so each view compares like with like.

›Where do the title keywords come from?

From the titles of the niche's outlier videos, with articles, filler words and platform words such as "video" left out. A keyword has to appear in at least three videos from two different channels, so one channel's series name can't top the list.
