A series playlist allows you to mark your playlist as an official set of videos that should be viewed together. Adding a video to a series playlist allows other videos in the playlist to be featured and recommended when someone is viewing a video in the series playlist. YouTube may use this information to modify how the videos are presented or discovered.
There are a few things to remember when using series playlists:
- You must have a verified account in order to use series playlists.
- A video cannot appear in more than one series playlist.
- Only videos uploaded by you and that you have the rights to can be added to a series playlist.
To enable a series playlist, visit playlist settings while on your computer and tick the box 'Set as official series for this playlist'.
