With the rise of product data, it is necessary to replace these crawler content and let real people enter the community and participate in the production of content, so it is necessary to build a content ecology of UGC. To achieve this goal, focus on three aspects: promoting UGC production, generalization of content, and building attention relationships. 1. Promote UGC production Real people are an important part of a community, and the content produced by real people is the most precious resource of a content community. Therefore, to be a content community, how to promote real people to produce content that conforms to the community is an important proposition for every community. As early as the first and second stages of the short video community, the author has already mentioned the importance of UGC in the article and the necessity of cultivating the platform's own UGC at an early stage—— In the case of accumulation in the early stage, in the third stage, the community should be able to master a group of relatively productive real-life authors. These authors will grow together with this short video community, whether it is production capacity or fan influence. Can be a community icon. However, if there is no such accumulation in the early stage, it is all crawled content. It takes a lot of work to cultivate real authors from scratch. The following three directions and means to cultivate and promote UGC production are proposed: 1. A large number of operational activities Operational activities are the means that can most directly affect the direction of production in the community. The main routine is to set up production activities with themes, such as the classic dog head shaking on the Douyin platform, and the “don’t judge me” fire on Musical.ly. And lip-synching activities, these classic activities and challenges provide a role model for all users in the community, telling them how to shoot and play short videos. With a lot of follow suit, many content consumers will be converted into content producers.
