In digital advertising, understanding how much you spend to reach your audience is essential for building an effective marketing strategy. One of the most commonly used metrics for measuring advertising costs is CPM, which stands for Cost Per Mille. The term “mille” means one thousand, so CPM represents the amount an advertiser pays for every 1,000 ad impressions.

What Is CPM?

CPM is a standard advertising metric used by marketers, publishers, and businesses to evaluate the cost of displaying an advertisement to a specific number of people. Instead of focusing on clicks or conversions, CPM focuses on impressions.

For example, if an advertising campaign has a CPM of $5, the advertiser is paying approximately $5 for every 1,000 impressions. This makes CPM particularly useful for campaigns focused on brand awareness, visibility, and audience reach.
