Cost Per Mille (CPM), also known as Cost Per Thousand Impressions, is a digital advertising metric that measures the cost of serving 1,000 ad impressions to users. It’s calculated by dividing the total cost of the campaign by the number of impressions (in thousands). CPM is commonly used in brand awareness campaigns where visibility is prioritized over clicks. It helps advertisers assess reach efficiency and compare performance across display, video, and social media channels.
