Does CPM measure the cost per individual user action?

The concept of CPM, or Cost Per Mille, specifically refers to the cost of advertising per one thousand impressions rather than measuring the cost per individual user action. CPM is a pricing model widely used in digital advertising where advertisers pay for every thousand times their ad is displayed, regardless of whether users interact with the ad or take any specific action.

The focus of CPM is entirely on impressions rather than actions taken by users, such as clicks, conversions, or any other form of interaction with the ad. This pricing model is typically used when the goal is brand awareness or exposure, rather than direct engagement or action by users.

In summary, CPM does not assess individual user actions; instead, it quantifies the cost associated with obtaining exposure through impressions, which clearly aligns with the idea that it does not measure the cost per specific user action.
