- Cost per Mille (CPM): Cost per Mille (CPM), also known as cost per thousand, is a marketing term used to denote the price of 1,000 advertisement impressions on one webpage. If a website publisher charges $2.00 CPM, it means an advertiser must pay $2.00 for every 1,000 impressions of its ad.

How CPM is Used in Digital Ads
CPM is key in digital marketing because it allows advertisers to measure the cost-effectiveness of a campaign based on impressions rather than actions. It is especially useful in brand awareness campaigns where the objective is to expose the brand to as many people as possible.
