CPM (Cost Per Mille)
The cost to reach one thousand impressions — the standard unit of paid reach pricing.
Also known as: CPM · Cost per mille · Cost per thousand
CPM (cost per mille) is the cost to deliver one thousand impressions. It is the default pricing unit for awareness-led media.
CPM measures the price of attention, not of outcomes. Creator commerce uses it as an input but optimizes on cost-per-outcome metrics like CPC, CPA and ROAS instead.
