CPM (Cost Per Mille) is the cost per thousand impressions, one of the most common pricing models in digital advertising. CPM = (Total Ad Spend / Impressions) × 1000.
CPM = (Total Ad Spend / Impressions) × 1000. Example: $500 spent for 100,000 impressions → CPM = 500/100000 × 1000 = $5 per thousand impressions.
CPM charges per thousand impressions, CPC (Cost Per Click) charges per click. CPM is better for brand awareness campaigns, CPC for performance campaigns. CPM is usually cheaper but CTR is not guaranteed.
CPM varies by industry, region, and targeting. Display ads typically $2-10, video ads $15-25. Highly targeted audiences have higher CPM.
