CPA (cost per action), this pricing method refers to charging according to the actual effect of the advertisement, that is, charging according to the valid questionnaire or order replied, not limited to the amount of the advertisement. The pricing method of CPA has certain risks for the website, but if the advertisement is successful, its income will be much greater than CPM. In order to avoid the risk of advertising costs, advertisers only pay the advertising site fees according to the clicks after the network users click on the banner advertisements and link to the advertisers' web pages. So this charging model is risk-free for advertisers, but it is not very popular for website owners.
