CPM cost per thousand people in the advertising process. For example, if the unit price of an advertisement is 1 yuan /CPM, it means that every thousand people will receive 1 yuan when they see the advertisement, and so on. 10000 people visited the homepage of 10 yuan. ?

CPC should pay per click, and it is not good for advertising companies to pay per click, so it is rarely done.

Generally speaking, CPA should be regarded as paying according to the effect, that is, charging according to the valid questionnaire or order in the reply, rather than limiting the amount of advertising. This is risky for advertising companies, so our company usually takes the form of advance payment.

CPS converts the advertising amount according to the actual number of products sold.
