CPM is a term used to describe a digital advertising revenue model where an agreed amount is paid by an advertiser for every one thousand impressions. CPM stands for ‘cost per thousand’ viewers, even though the acronym literally translates to “cost per mille,” which is Latin for ‘thousand.’ For example, if a website or online publisher charges $1 CPM for a digital ad, the advertiser must pay $1 for every one thousand impressions that ad generates.
