What is the charging standard in baidu promotion?

Baidu's advertising charging project involves two steps: first, when opening an account, you need to deposit a promotion fee in advance; Second, after opening an account, when it is officially launched, it will be charged according to the click price of each keyword. This is divided into industries and keywords. Different industries, different keywords, prices generally vary greatly. Generally speaking, the prices of highly competitive industries and keywords are generally higher, while the prices of less competitive industries and keywords with lower search degree are relatively lower. In addition to a pre-paid promotion fee when opening an account, Baidu's advertising fee standard is calculated according to the click volume of a keyword. Specifically, only when a potential customer (emphasizing that anyone who is interested in clicking on the promotion information of the enterprise is equal to the potential customer of the enterprise) clicks on the advertising information once, the enterprise needs to pay a fee to Baidu, which is deducted from the promotion account of the enterprise. That is, the promotion cost of the enterprise = the charge per click of the enterprise promotion information is added together. Click to charge, and the demonstration is free.
