Community marketing is a marketing method that builds brand image, publicizes product information and interacts with users on social platforms such as social media and online forums, so as to increase brand awareness, improve user loyalty and promote sales. Its essence is to establish communication channels between brands and users, and achieve marketing goals by interacting with users, building trust and providing value. The focus of community marketing is to establish a two-way interactive relationship with users, rather than the traditional one-way promotion.
