Anything except "adult content" can be compiled into a TikTok Series -- from cooking, exercise, beauty, to lifestyle content, and beyond. Regular TikTok videos can be up to 10 minutes long, so doubling the runtime can allow creators to deliver more detailed content to their viewers. Although the new feature gives creators more leverage over their TikTok earnings, TikTok Series content must still abide by TikTok's Community Guidelines.
