Behind the rankings
A little context.
What does “most watched” mean?
Videos must have been published in the last 24 hours, 7 days or 30 days. Within each window, we sort the reactions we discover by their latest total public view count. These are lifetime views, not views gained during that window. A video can appear in more than one window.
How often do the rankings update?
The collection schedule runs every four hours. Each platform shows the time its data was actually collected. If an update is delayed, we keep the last available results for up to 24 hours and continue removing videos that fall outside each time window.
Does this cover every reaction video?
No. Rankings are a sample of discovered reaction videos, not an exhaustive chart of either platform. YouTube discovery uses reaction and first-watch/listen searches; TikTok coverage depends on the connected data source. Videos need a clear reaction signal in their title or caption to qualify. Platform view-count definitions differ, so use the platform filters to compare within a single service.
Can I watch videos here?
Yes. Select a video to open its official player. Videos load only when you choose to watch, and the original source link stays available if playback is restricted.
