How does the TikTok algorithm recommend videos to users?

TikTok acts like a super-smart friend who knows exactly what you like and shows you more of it.

Imagine you're playing with your favorite toy box. Every time you pick a toy, your friend notices which one you choose and adds more of those toys to the top of the box so you can find them easily next time. That’s kind of how TikTok works!

When you watch a video on TikTok, it's like picking a toy from the box. The app sees what you're watching and thinks, "Hey, they liked that one!" So it adds more similar videos to your list, just like adding more of those toys to the top.

TikTok also watches how long you stay on a video. If you watch all the way to the end, it’s like saying, "I really like this toy!" But if you tap away quickly, it’s like saying, "Not this one."

So every time you use TikTok, it gets smarter and smarter about what you like, just like your friend who knows exactly which toys make you happy!
