What does CPM stand for?

CPM stands for Cost Per Mille, where "mille" is Latin for one thousand. It represents the price an advertiser pays for 1,000 ad impressions. It is the most common pricing model in display and programmatic advertising.

What is the CPM formula?

CPM = (Total Budget / Total Impressions) × 1,000. Rearranged: Budget = (CPM × Impressions) / 1,000, and Impressions = (Budget / CPM) × 1,000.

What is a good CPM for digital advertising?

CPM varies widely by channel and audience. Display ads typically range from $1 to $10, Facebook and Instagram from $5 to $15, LinkedIn from $30 to $90, and programmatic video from $10 to $30. Context, targeting, and competition all affect the rate.

Is CPM the same as CPI?

No. CPM (Cost Per Mille) measures the cost per 1,000 impressions. CPI (Cost Per Install) is a mobile-specific metric that tracks the cost for each app installation. They measure different actions.

How is CPM different from CPC?

CPM charges advertisers per 1,000 impressions regardless of clicks, making it ideal for brand awareness. CPC (Cost Per Click) charges only when a user clicks the ad, making it better suited for direct-response campaigns.
