What is Cost per Thousand (CPM) Impressions?

In the world of digital advertising, there are many terms and acronyms that can be confusing to those who are not familiar with the industry. One such term is Cost per Thousand (CPM) Impressions. In this article, we will break down what CPM impressions are and how they are used in digital advertising.

Understanding CPM Impressions

Ad impressions

CPM stands for Cost per Thousand, with the “M” representing the Roman numeral for one thousand. CPM impressions refer to the cost an advertiser pays for one thousand ad impressions. An ad impression is counted each time an ad is displayed on a webpage or app. CPM is a common pricing model used in digital advertising, where advertisers pay for the number of times their ad is displayed, rather than the number of clicks or conversions it generates.

How CPM Impressions are Calculated

To calculate the cost per thousand impressions, the total cost of the ad campaign is divided by the number of impressions generated. This number is then multiplied by 1,000 to get the cost per thousand impressions. For example, if an advertiser pays $100 for an ad campaign that generates 50,000 impressions, the CPM would be $2 ($100/50,000 x 1,000).

Why CPM Impressions are Important

CPM impressions are important because they allow advertisers to reach a large number of potential customers at a relatively low cost. This pricing model is especially beneficial for brand awareness campaigns, where the goal is to get the ad in front of as many people as possible. CPM impressions also allow advertisers to target specific demographics or interests, ensuring that their ad is seen by the right audience.

CPM Impressions vs. Cost per Click (CPC)

CPM impressions are often compared to another common pricing model in digital advertising, Cost per Click (CPC). While CPM impressions focus on the number of times an ad is displayed, CPC focuses on the number of clicks an ad receives. In a CPC model, advertisers only pay when someone clicks on their ad, whereas in a CPM model, they pay for every impression, regardless of whether or not it leads to a click. Both models have their advantages and are used for different types of campaigns.

Factors Affecting CPM Impressions

The cost of CPM impressions can vary depending on a few factors. These include the type of ad being displayed, the platform it is being displayed on, and the target audience. For example, ads on social media platforms tend to have a lower CPM than ads on search engines. Additionally, targeting a specific demographic or interest may increase the CPM as it narrows down the potential audience.
