CPM stands for cost per thousand, where "mille" is Latin for "thousands". It is a pricing model used in digital marketing where an advertiser pays for every 1,000 impressions of their advertisement on a web page. An impression is counted when an ad, as an element of a web page, loads and receives a view. CPM is one of several methods used to price online ads, with others including cost per click (CPC) and cost per acquisition (CPA) . CPM is often used in campaigns that are designed to be seen by thousands of people and is ideal for social campaigns and online marketing strategies that focus on heightening brand awareness and delivering specific messages. It is a valuable metric for marketers and advertisers as it gives insight into the level of brand awareness and recognition, as well as which ads and content types are most successful among the audience.
