What does CPM stand for in advertising?

CPM stands for Cost Per Million, a term commonly used in advertising to denote the cost of reaching one thousand impressions or views of an advertisement. It is a crucial metric for advertisers as it provides a standardized way to compare the cost efficiency of different advertising campaigns and media options. By calculating CPM, advertisers can assess the value of their advertising spend relative to the number of people who are exposed to their message, helping them to make informed decisions about where to allocate their budgets for maximum impact.

The other terms do not represent established advertising metrics, which is why they do not fit in this context. Cost Per Medium might imply expenses associated with different advertising mediums but lacks specificity regarding performance metrics. Cost Per Measurement is vague and does not directly refer to a standard in advertising metrics. Cost Per Marketing could suggest expenses related to various marketing activities without a clear link to impressions or viewer reach, which are essential in evaluating the effectiveness of ad spend.
