In the customer acquisition link, traffic should be guided from public domains such as social media, e-commerce platforms and offline stores to private domains such as WeChat groups and official WeChat accounts. For example, offline stores can guide customers to add WeChat friends by giving small samples, and e-commerce platforms can insert private domain QR codes in product packages. In the customer operation link, user stratification should be carried out according to consumption capacity, skin type and consumption preferences, and personalized content should be pushed. For example, push skincare tips for sensitive skin to sensitive skin users, and push makeup tutorials for office scenes to office workers. Regular interactive activities should be held in private domains, such as online skin care lectures, product experience sharing sessions, and group purchase discounts, to enhance user activity. A member points system should be established, and points can be exchanged for products or services to improve user stickiness. In terms of service conversion, exclusive offers and customized product recommendations should be provided for private domain users. For example, launch limited-time discounts for members in WeChat groups, and recommend suitable products according to user consumption records. In addition, a user feedback mechanism should be established to collect user opinions and suggestions in a timely manner and optimize products and services.
