CPM marketing, or Cost Per Mille marketing, refers to an advertising pricing model where advertisers pay a set fee for every thousand impressions (mille is Latin for thousand) their ad receives. This model is widely used in online advertising, especially for display ads, video ads, and other visual formats.

In CPM marketing, the focus is on brand visibility rather than immediate clicks or conversions. Advertisers benefit from increased exposure to a large audience, making it a popular choice for businesses looking to enhance brand awareness.

CPM is particularly effective for campaigns aimed at building brand recognition, as it allows advertisers to reach a broad audience across various platforms, including websites, social media, and mobile apps.

One advantage of CPM marketing is that it enables advertisers to control their budgets more effectively. Since costs are based on impressions, brands can predict their spending more accurately over the campaign's duration.
