O2O e-commerce refers to the offline consumption of online stores. Merchants show their business information and commodity information to consumers by opening online stores for free. Consumers choose to spend and pay offline after online screening service and offline comparison experience. This can not only greatly meet the individual needs of consumers, but also save the cost of consumers not spending because of online payment. Merchants spread information faster, farther and wider through online stores, and can instantly gather strong consumption power. The main feature of this model is that both merchants and consumers meet the needs of both parties through O2O e-commerce. \ x0d \ x0d \ O2O service industry has a wide coverage, a large number of enterprises and strong regionality, so it is difficult to advertise on TV and Internet portals (Sina and Sohu). The O2O e-commerce model can fully meet the needs of this market. \x0d\ For local businesses, it can spread faster, farther and wider through online stores, and it can instantly gather strong consumption power, which also solves the problem that online marketing of group-buying goods cannot be normalized and real-time. Merchants can publish the latest group purchase, discount, free and other service preferential activities in real time according to the operation of the store to increase sales. \x0d\ For consumers, through online screening service, offline comparison and experience, they can make selective consumption. O2O provides rich, comprehensive and timely information on group purchase, discount and free, and can quickly screen and experience goods or services. It not only meets the individual needs of consumers, but also saves the cost of consumers not spending because of online payment. It also prevents the customized physical goods from being inconsistent with the consumer's reservation. Once the quality is lower than expected, or even extremely inferior, consumers will be in a very passive position. \x0d\ For service providers, online to offline can bring large-scale and high-viscosity consumers and win more business resources.
