On other platforms like YouTube for example, there are a lot of factors beyond the video itself that influences if a person even clicks on it (like the thumbnail, the title, the number of views, who the creator is), so if someone doesn't click on a video, that doesn't tell you if they would have liked it or not. Because of that your data to make recommendations isn't as accurate.
That's the main difference I see with TikTok. They make recommendations proactively, instead of reactively.
Instead of presenting a list of recommendations (like YouTube, Netflix or Instagram does), TikTok infers what it thinks you will like and directly shows it to you. Then based on how you react: if you like the video, follow the creator, watch it until the end, or swipe away, they know with much more accuracy the type of content you enjoy. This allows for more testing on their part too.
