Short or Long Videos

Do shorter videos get better results on TikTok or longer ones?

It depends on your niche, and how engaging your video is. As far as results go, if you're looking for views, the shorter ones get viewed more. Like more of the whole video. I don't think TikTok's algorithm is like Facebook's in the sense that on Facebook, you get more algorithm love if somebody watches
up to 3 minutes of your video. I've never heard that TikTok does that.
