TikTok explains how its algorithm really works

Tiktok has revealed greater insight into how its recommendation algorithm works in a new blog post. The algorithm uses a number of factors to base its suggestions of 15-second clips. Theses include user interactions, such as the videos a user likes or shares, accounts they follow, and comments posted as well as video information such as sounds and hashtags. Tiktok will use your device and language settings to "make sure the system is optimised for performance" but receive lower weight compared to the other metrics "since users don't actively express these as preferences." Many of TikTok's algorithm influences will be familiar; similar features are offered by other social media sites such as Twitter and YouTube upon setting up a new account.
