CPM (Cost Per Mille)
Definition
CPM is the cost of one thousand impressions, a standard way to compare distribution efficiency.
Full explanation
CPM (cost per mille) divides spend by impressions, then multiplies by 1,000. In creator-powered distribution it is used to compare the efficiency of campaigns, creators, and platforms on a like-for-like basis.
Why it matters
CPM lets brands compare distribution cost across very different channels and budgets.
