The category of Tik Tok can be understood as the field of its own video, a general direction of its own video, such as food, music, TV and movie reviews and so on. The vertical content of Tik Tok is that his video content is consistent with his chosen field, and the output of an account should always be the same content. If today is a funny joke, tomorrow is cooking and the day after tomorrow is fitness, then there is no doubt that he is a video creator without vertical content. Vertical classes are directly linked to traffic pools. If you don't fix your own vertical category, the flow cannot be guaranteed. This is why many Tik Tok TV anchors choose to create a new number directly when they want to change the vertical classification. Tik Tok's fixed vertical interest and flow pool relationship; Tik Tok will allocate a traffic pool for each work according to the algorithm. Even if Tik Tok is a new user with 0 fans and releases any video, Tik Tok system will intelligently allocate dozens or even hundreds of traffic, that is, traffic pool. Then decide whether to push his works to more people according to his performance in this traffic pool. No matter how big, as long as you have the ability to produce high-quality content, you will have the opportunity to compete with big competition. Evaluation criteria of Tik Tok mobile pool: praise, comment, forwarding and broadcast completion rate. In other words, a new video has a high broadcast completion rate and a high interaction rate, and this video has the opportunity to continue to increase traffic. In Tik Tok, all the videos that broke the news overnight, as well as those recommended by Tik Tok, are basically millions of broadcasts, and the comprehensive data (broadcast rate, likes, comments and forwards) are all high without exception. It can be seen that after a large number of users' audits, layers of heat weighting, it entered the recommended content pool of Tik Tok and was baptized by tens of millions to millions of traffic. The weight of each heat is: forwarding volume >; Comments > likes. The weight of heat will also change with time. An explosive video has been on fire for a week. Unless a large number of users imitate and follow up, a stable content update mechanism and the ability to continuously output explosions are needed.
