In this case, every 1000 impressions of one ad are paid. This model is characterized by unpredictability, so if the settings are not correct, the result may be disastrous.
The main parameter for CRM is the conversion of impressions. If this indicator is low, PR may not bring results for a long time. The CRM model is different in that the final price does not depend on the clickability of the ad. Money is written off after the ad is shown 1000 times.
There are two types of this model - fixed and auction. The physical therapist email list price is formed by analogy with CPC. The fixed cost is used for targeting and is set in the advertising campaign settings. in VK Advertising.
In the auction format, only the maximum bid can be changed, and the amount received during the auction will be written off.
Paying for 1000 impressions is suitable during the period of "testing the waters". For example, when a company enters a market or launches a new product.
CPE (“Cost-Per-Engagement” - payment for interaction)
When using this model, the calculation is only for users who somehow interact with the ad. For example:
fix the cursor on PR (Google Ads interactive lightboxes);
put likes (PR on Facebook);
hover over PR (Google Ads interactive lightboxes).
The scenarios may be different, but they all have one thing in common: you will only pay for those people who are willing to interact with the advertisement.
CPC (Cost-Per-Click)
In this case, the cost can be set manually by the advertiser, or it can be formed automatically according to the auction principle. You can pay for clicks using this system in the contextual PR services Google Advertising or Yandex.Direct. Auction CPC is set up simply. You need to specify the maximum rate that you agree to pay for each click.
CPM (“Cost-Per-Mile” - payment per mile)

In this case, the money will be written off in the amount formed at the auction. For example, the advertising campaign lasted several days, and 17,000 rubles were spent on it. As a result, 1,800 clicks were received. It turns out that each of them cost 9.5 rubles.
The CPC model cannot be used for display advertising, since the important parameter there is ad impressions and you need to have as many of them as possible.
CPI (Cost-Per-Install)
This model can be selected in Google Ads (by setting the goal "Advertising apps") or in myTarget. But it is more popular in affiliate networks that are used for PR of applications for mobile devices.
Yandex.Direct does not provide such a model. There you can use a ready-made format for advertising. Let's assume that 10,000 rubles were spent on PR, and 40 installations were made during the campaign period. Then the CPI value is 250 rubles.
For the CPI model to give a good effect, you need to know at least the approximate cost of the paid action.
The disadvantage of CPI is that there is a possibility of artificial installations and getting into motivated traffic. Unscrupulous users often fake the installation of applications. Tasks for this work are usually posted on specialized exchanges. Another disadvantage of CPI is the high cost of advertising compared to other types.
