At present, among the Audi users, users of the second age group (5-7 years old) account for about 30%. According to data analysis, these users have gradually lost to the external market. It is now necessary to attract “dormant” users back to the store through strategic marketing methods. If these users are successfully recruited back to the store for maintenance, they are new business increments for manufacturers and distributors. We have planned and designed a series of interactive H5 interactions to activate old users. Increase the sales of original spare parts; enhance the satisfaction of Audi users, and reflect the brand care of Audi manufacturers for old users.
