CPM (Cost Per Mille)

Metrics

The price you pay per thousand ad impressions — "mille" is Latin for thousand. It's the default pricing model for awareness and reach buys, where you pay to be shown rather than for clicks. CPM = (total spend / impressions) × 1000.

Example

Spending $50 to serve 10,000 impressions is a $5 CPM.
