Category selection requires comprehensive consideration of factors such as market demand, own interests, and competition, so different people and different stores may have different preferences and strategies. But in general, Doudian product selection needs to pay attention to the following points: Category selection should be determined based on market demand and its own advantages. Market demand is what Douyin users are most concerned about. Current popular trends must be taken into account, while at the same time not ignoring their own strengths and advantages, such as sports and beauty. Be sure to choose products that you understand and can produce good results. At the same time, you need to understand the competitive situation and choose categories that are competitive but not too saturated, so as to better attract users. In addition, try to choose stores with a single category, and don't pile up strategies, otherwise users will feel unprofessional. Finally, Doudian product selection must also consider operating costs and retention rates, and these factors will also affect the long-term development of the store.
