Understanding CPM (Cost Per Mille) in E-commerce
Quick Definition
Cost Per Mille (CPM) is a digital advertising pricing model where advertisers pay for every 1,000 ad impressions served. It represents the cost an advertiser pays for 1,000 views of their online advertisement, regardless of clicks or conversions. CPM helps marketers evaluate and compare advertising efficiency across different platforms and campaigns.
