Community marketing refers to a sales method that takes customers as the center, invites customers with the same characteristics to build a group, and then formulates corresponding preferential policies for sales.

Community marketing is a commercial form based on the same or similar interests, gathering popularity through certain carriers, and meeting the needs of groups through products or services.

Compared with some fast-moving consumer goods, the prices of most building materials and household products are still relatively high, and customers' consumption of such products is irrational, so it is difficult to stimulate customers' consumption impulses and behaviors. Therefore, "community" has become a good carrier, which can continuously affect consumption, thus increasing the viscosity of customers and businesses and repeating consumption behavior. Through online community management, businesses can continuously improve customer dynamics for a long time, which greatly avoids the loss of intentional customers.
