Cost per mille (CPM) is a metric commonly used in the advertising industry to determine the cost of a thousand ad impressions. This helps advertisers and publishers evaluate and compare the effectiveness of various advertising channels. Calculating CPM is a simple process, and in this article, we will outline the seven steps you need to take to calculate it.
1.Determine your advertising goals:Before calculating the CPM, consider what you hope to achieve with your advertising campaign. Do you want to increase brand awareness, drive more traffic to your website, or generate more sales? Understanding your goals will help you assess your CPM results and guide your ad budget.
2.Track impressions:The first step in calculating CPM is determining the total number of impressions generated by your ad campaign. One impression is counted each time an ad is displayed, whether or not a user clicks on it.
3.Calculate total ad spend:To get an accurate CPM value, you must know how much money has been spent on a specific advertising campaign. Add up all expenses associated with creating, launching, and maintaining that particular campaign.
4.Convert impressions to thousands:Since CPM is concerned with ad costs per thousand impressions, divide the total number of impressions obtained in step 2 by 1,000.
5.Divide total ad spend by converted impressions:Take the total ad spend from step 3 and divide it by the converted impressions obtained in step 4.
6.Round off the result:The final value is usually expressed as a whole number; hence rounding off is recommended for easy interpretation.
7.Analyze and compare CPM values:With this calculated CPM value, you can now compare it against other marketing channels or assess its effectiveness relative to your initial goals.
Here’s a simple example:
Assume an advertiser spent $5,000 on an online campaign that resulted in 250,000 ad impressions.
Step 1: Goals = Increase brand awareness
Step 2: Impressions = 250,000
Step 3: Total ad spend = $5,000
Step 4: Converted impressions = 250 (250,000 / 1,000)
Step 5: CPM calculation = $20 ($5,000 / 250)
Step 6: Rounded CPM = $20
Step 7: Analyze and compare with other channels or against initial goals.
Calculating the CPM of your advertising campaign is crucial to understanding its effectiveness and guiding your advertising budget. By following these seven steps, you can now accurately measure your CPM and optimize your marketing strategy accordingly.
