Everyone tells authors to “use BookTok hashtags”. Nobody tells them which ones carry anything. We scan 582 book hashtags and record, for each one, how many videos we read and how many plays those videos carried — so you can see reach and crowding as measured numbers instead of folklore. Every figure below is a snapshot with its own scan date.
The forty hashtags whose scanned videos carried the most plays each. Counted from the scan dates shown.

36 lanes carry at least 3 hashtags of their own, which is the floor for giving a lane its own page — below that there is nothing on it you would not already have from the general list above. The general hashtags apply to every lane.
Every row is a dated snapshot, not a live counter and not a lifetime total. For each hashtag we read a sample of its videos on the date shown and counted the plays those videos carried. “Plays per video” is that total divided by that sample. TikTok counters move by the hour; a figure scanned in May is a May figure and is labelled as one.
Reach vs median compares a hashtag’s plays per video against the median across all 582 hashtags we track, which is 323,267 plays per video. Three times the median or better is called high reach; at or above the median, above median; below it, below median. That is the whole rule.
Use it the way it is built: a hashtag with high plays per video and few videos is reach you can still get into; high plays and very many videos is a hashtag you will be shouting under. It is a measurement, not a promise — nothing here predicts what your video will do.
4,857 scans across 582 hashtags and 137 subgenre lanes, first scan 2026-05-11, most recent 2026-08-26. The same figures are available as JSON with ?format=json.
