What is cost-per-impression?

Cost-per-impression (CPI), often abbreviated as CPM (cost-per-mille, where "mille" is Latin for thousand), is a key metric in online advertising. It represents the cost an advertiser pays for one thousand views or displays of an advertisement. An "impression" signifies that an ad has been loaded and potentially seen by a user, regardless of whether they clicked on it. This model is particularly useful for campaigns focused on achieving brand awareness and maximizing reach, rather than direct clicks or conversions. To calculate CPI, the advertiser typically divides the total cost of the campaign by the number of impressions, then multiplies by one thousand to get the cost per mille. It helps advertisers understand the efficiency of their ad spend in terms of ad visibility and how many potential customers saw their message. More details: https://azstats.org/site/4mama.com.ua/
