Cost-per-impression (CPI), often abbreviated as CPM when referring to "cost per mille" or cost per thousand impressions, is a fundamental metric in digital advertising. It quantifies the price advertisers pay for each instance their ad is displayed to a user, regardless of whether the user interacts with it. Essentially, CPI is calculated by dividing the total cost of an advertising campaign by the total number of impressions generated. This model is primarily used for branding and awareness campaigns where the goal is maximum visibility rather than immediate clicks or conversions. Unlike cost-per-click (CPC) or cost-per-acquisition (CPA), CPI focuses solely on the exposure an advertisement receives. Advertisers utilize CPI to gauge the efficiency of their ad spend in terms of audience reach and brand exposure across various platforms. It's a valuable tool for understanding the cost of simply getting an ad seen by potential customers. More details: https://info-list.top
