How does the 'TikTok algorithm' personalize content for users?

The TikTok algorithm is like a super-smart friend who knows exactly what you like and shows you more of that.

Imagine your toy box has all kinds of toys, cars, dolls, blocks, and balls. Every time you pick one to play with, your smart friend notices which toy you choose. Then, next time, they give you more of the same kind of toy, because they know you like it! That’s how the TikTok algorithm works: it watches what videos you watch, like, and share, and then shows you more videos that feel just right.

Every time you tap on a video, the algorithm gets excited, it's like getting a thumbs-up from your friend. If you watch the whole video, or even pause for a bit, it knows you really liked it.

If you skip a video quickly, it takes note too, maybe that one wasn’t as fun.

Once it knows what you like, the algorithm starts showing you new videos that are similar to the ones you’ve enjoyed before. It's like getting a surprise toy every day, but instead of toys, you get videos that feel just right for you.
