What does CPM stand for in advertising terms?

CPM stands for "Cost per Mille," where "Mille" is a Latin term meaning "thousand." In advertising, CPM is a metric that represents the cost an advertiser pays for one thousand impressions or views of an advertisement. This measurement is critical for advertisers because it helps them understand the cost efficiency of their advertising campaigns concerning how many times their ad is displayed to users.

Using CPM allows marketers to compare the cost of advertising across various platforms and formats, making it easier to assess how well their budget is being utilized. It is particularly relevant in the context of digital advertising, where the aim is often to maximize visibility and engagement within a set budget.

Other options mentioned do not accurately reflect the established terminology in marketing and advertising. The correct understanding of CPM is foundational for advertisers seeking to evaluate and optimize their media buying strategies effectively.
