The Cost Per Thousand impressions. The price charged for a thousand ad views.
CPM is the oldest and most universal pricing method. If an ad network sells its space at a €5 CPM, the advertiser will pay €5 every time their banner or video has loaded a thousand times on user screens.
CPM determines the level of competition on a platform. The more sought-after an audience (e.g., CEOs on LinkedIn, or Prime-Time TV), the higher the CPM.
"We massively negotiate CPMs (Television, OOH, Programmatic) thanks to the agency's volume, allowing us to buy the same audience as our competitors, but at a significantly lower net rate, mechanically boosting the final ROAS."
