Which of the following terms represent cost per 1000 impressions?

CPM stands for Cost Per Mille (or Cost Per Thousand), where "Mille" is Latin for thousands. It is a standard metric in advertising used to denote the cost an advertiser pays for one thousand views or impressions of an advertisement. This metric helps advertisers understand the cost-effectiveness of their ad campaigns in terms of exposure. CPV (Cost Per View) is a metric typically used for video advertising, where the advertiser pays for each view of their video ad, rather than just an impression. CPCV (Cost Per Completed View) is a more specific video advertising metric where the advertiser pays only when a video ad is watched to completion. These metrics are distinct from CPM, which focuses solely on impressions.
