What is a TikTok Video?
A TikTok video shouldn’t be thought of as one piece content, but as a series of inputs to be analyzed by the platform’s artificial intelligence — the caption, the hashtag, the length of the video, the audio, the filters used, the comments, the accounts the commenters follow, the accounts you follow, etc. All of it creates branches of recommendations to offer you.
