Hot spots refer to news or information that the masses are concerned about, or are popular, or refer to conspicuous places or problems in a certain period. Such as "social hotspot" and "Mianshan has become a tourist hotspot". According to Tik Tok algorithm, the first five video works of all new accounts are the key to determine the initial weight of accounts. The higher the user fan feedback data obtained from these five videos, the higher the initial weight. Another example is the WeChat video number, and the three works released in the early stage are also very important! In addition, it is said that the videos posted by Tik Tok's new account are more popular in the system and easier to recommend than the old account. For example, after the new Tik Tok determines the initial weights of the first five videos, the following four main factors will affect the weights of subsequent accounts. That is, the number of plays (play completion rate), the number of likes, the number of comments and the number of forwards. The importance of these four factors from high to low is: broadcast volume (completion rate) >; Like > comment > forward.
