YouTube Playlist Health Check

A playlist health check looks for the problems that build up in long playlists: videos that were deleted or made private, and videos added twice. Both stay in the list, so viewers hit a blank entry or watch the same lesson again.

The report gives the position of each broken or repeated entry so you can fix it quickly in YouTube Studio. It also shows how video lengths are spread and estimates drop-off, comparing each video's public views with the first video's to show where viewers tend to give up. Creators use it to keep their own courses tidy, and learners use it to check a playlist before committing to it.

When a video in a playlist is made private or deleted, it stays in the list as a blank entry that viewers can't play. Long playlists collect these over time, along with videos added twice by mistake. The health check lists each one with its position so it's quick to fix.

Drop-off is estimated from public view counts: each video's views as a share of the first video's. A steady slope is normal for a course. A sudden drop points to the video where many viewers give up, which is a good place to look at pacing or split a long lesson.
