The Douyin Store Selection Alliance is a platform that brings together multiple small businesses. Through joint promotion and mutual communication, it achieves the goal of increasing exposure and sales. Its effectiveness depends on the quality of specific alliance members and the way of cooperation. If the alliance members are of high quality, can trust each other and work together, then the alliance will be able to bring more traffic and revenue. But if the quality of members is uneven and the way of cooperation is not good, then the alliance may have a counterproductive effect, leading to competition and conflict among members. In short, the Douyin Store Selection Alliance can be effective, but member selection and cooperation methods need to be carefully considered.
