If a WeChat friend likes a certain video number, it will be displayed in the form of little red dot+friend's avatar in the discovery interface. At first, the author thought that a red dot prompt had played a certain role, but there was a friend's head. The stickiness of social products is inseparable from the interaction of friends. Bringing a friend's head is intimate, and showing a friend's praise will, to a certain extent, trigger users to do the next step because of curiosity and concern. This interface is all video content praised by friends. Unlike Tik Tok, Tik Tok recommends his favorite videos according to the algorithm, so he never knows what the next video content is, and the more he watches it, the more addicted he becomes.

The video number is recommended to users through videos praised by friends. Watch the video number for a while. The default interface is the video recommended by friends. I found that most of my favorite friends' video numbers are of one kind (such as keeping in good health) and some of them are (chicken soup), which is obviously not their favorite content. There are only dozens of people brushing them back and forth, and there are too many repetitive contents.

Yesterday, I opened the "Discovery" interface, and a hot search topic appeared, as shown below.

Recently, the hot search topic "homework help and the ape tutor were fined 2.5 million respectively", and both Weibo and Tik Tok went on the hot search. The video number prompt method adds a hot search topic, which means that not only friends recommend red dots, but also a hot search topic, which makes content recommendation more abundant.
