Cost Per Mille (CPM) / Cost Per Thousand Impressions

Cost Per Mille (CPM), also known as Cost Per Thousand Impressions, is a common pricing model in online advertising where advertisers pay a set fee for every one thousand times their ad is displayed (Impressions). "Mille" is Latin for thousand. CPM is often used for Campaigns where the primary goal is Brand Awareness and Reach, rather than direct Conversions or clicks. It's calculated as:

CPM = (Total Cost of Campaign / Total Impressions) * 1000

This model is prevalent in Display Advertising and video advertising.
