  • Campaign Cost = (CPM * Impressions) / 1000
  • Impressions = (Campaign Cost / CPM) * 1000

Why Use CPM?

CPM is often used for:

  • Pricing display advertising campaigns focused on brand awareness and visibility.
  • Comparing the cost-efficiency of different advertising platforms or placements based on reach.
  • Budgeting for campaigns where the primary goal is getting the ad seen many times.

It differs from other models like CPC (Cost Per Click) or CPA (Cost Per Acquisition), which focus on user actions rather than just views.
