How the signal is measured
Signal Hunt observes public YouTube channels over time. It compares videos with their channel's own history instead of treating lifetime views as a trend.
Tracked coverage
Rankings include only channels and videos in the Signal Hunt index. They are not official global YouTube rankings and do not represent every upload on YouTube.
Stored observations
YouTube provides current public totals, not historical competitor timelines. Growth figures appear only after multiple snapshots have been collected; missing history is never estimated.
Comparable-age outliers
A video is compared with previous uploads from the same channel at a similar age after publishing. A 3× score means it had about three times the channel baseline at that observation point.
Confidence and samples
Outlier results require comparable uploads. Small samples are marked with lower confidence, and videos without enough observations remain in a collecting state.
Update cadence
New and fast-moving videos can be observed more frequently. Older videos are refreshed less often, so each page displays its latest observed timestamp.
Public API limitations
Subscriber counts may be rounded or hidden, topics and countries may be absent, and deleted or private videos can disappear. These limits are reflected rather than filled with estimates.
