詳しい定義
CPM is the standard pricing unit for awareness campaigns on every major ad platform. It lets you compare the cost of reaching audiences across networks without worrying about how many people click. Low CPMs are not automatically good — cheap impressions on the wrong audience waste money faster than expensive ones on the right one. Most SMM panels charge per thousand engagements, which mirrors the CPM logic.
