What does the acronym CPM stand for in the context of digital advertising?

In the context of digital advertising, CPM stands for Cost Per Mille. The term "mille" is derived from Latin, meaning "thousand." Therefore, CPM refers to the cost an advertiser pays for one thousand impressions of an advertisement. This metric is commonly used to price digital advertising campaigns, allowing advertisers to understand the cost-effectiveness of their ad spend based on the reach of their message to a large audience. By using CPM, advertisers can evaluate how much they are spending in relation to the visibility and exposure their ads are receiving.

Other options do not accurately reflect the standard terminology used in the advertising industry. While "Cost Per Minute," "Cost Per Message," and "Cost Per Marketing" might seem plausible in different contexts, they do not align with any widely recognized metrics in digital advertising. CPM, on the other hand, is a well-established term integral to measuring advertising effectiveness.
