Cost Per Thousand Impressions (CPM)

CPM (from the Latin term “cost per mille”) stands for “cost per thousand impressions.” It is a pricing model used in online advertising that is based on the number of times an ad is displayed, or “impressed,” on a website or other platform. In the CPM model, advertisers pay a fixed amount for every thousand times their ad is shown to users. This means that the more impressions an ad receives, the more the advertiser will pay. CPM is often used as a way to measure the effectiveness of an ad campaign, as well as to compare the relative value of different advertising options.
