Promotional advertisements are charged in the form of cpc (Pay per Click). Only when the user clicks on the advertisement, the merchant needs to pay the advertising fee, which will be deducted from the pre-charged amount of the account. In general cities and industries, the average price per click ranges from 1 yuan -8 yuan. The actual monthly investment varies greatly according to the city, location, industry and actual demand of the merchants, ranging from 2000-3000 yuan/month/store to tens of thousands of yuan. It should be noted that the promotion budget can be flexibly set according to the changes of competitive environment, off-season and the actual needs of merchants, and can be adjusted or even suspended at any time.
