Free mode is the best marketing mode of drainage, interception, financial retention and return, and it is also the best business mode. A business model that customers can't refuse! !
The free mode is to attract a large number of customers, extend the industrial chain, tap invisible profits, realize cross-subsidies and earn invisible money through the spirit of losing money and being altruistic.
Any loss model, he must have a profitable product to make up the account, or a back-end to make money. If I don't take these two factors into account, the more activities you engage in, the more you will suffer, and I suggest that you must master the "three-limit principle" when engaging in activities.
The success of any activity is inseparable from these four steps:
Drainage-interception-backflow-capital flow (these four steps)
Drainage: guide customers to irresistible interception: intercept customers' nerves.
Reflux: back to the customer, lingering.
Wealth flow: wealth is willing to give to customers.
