CPM

CPM stands for "cost per thousand impressions." It is a pricing model used in online advertising that refers to the cost of an ad campaign or individual ad placement based on the number of impressions it receives. CPM is calculated by dividing the cost of the ad campaign by the number of impressions in thousands. For example, if an ad campaign costs $500 and receives 500,000 impressions, the CPM would be $1.00 (500 / 500,000 * 1,000). CPM is often used to compare the relative cost-effectiveness of different ad campaigns or placements.
