CPM, or Cost Per Mille, is a fundamental digital advertising metric that measures the cost an advertiser pays for every 1,000 ad impressions served to users. The term “mille” derives from the Latin word for thousand. In CPM-based campaigns, advertisers are charged based on the number of times their advertisement appears on a webpage or platform, regardless of whether users click on it or take any action. This pricing model is prevalent across display advertising, video platforms, and social networks, making it essential for budgeting and comparing advertising efficiency across different channels and campaigns.
For B2B marketers on LinkedIn, CPM is particularly valuable for brand awareness initiatives where the goal is maximizing visibility among decision-makers and professionals in your target industry. LinkedIn’s CPM rates tend to be higher than other platforms due to the professional audience quality and intent. Understanding and optimizing your CPM helps B2B marketers allocate budgets efficiently, reach the right executive audience at scale, and measure campaign performance relative to awareness objectives rather than immediate conversions.
