What do CPM and CPC mean?
CPM and CPC are terms used to calculate rates for Internet Advertising. CPM stands for Cost Per (M is Roman numeral for 1,000) thousand impressions. CPC stands for Cost Per Click. The CPM model only guarantees that your ad will be shown to users, but does not guarantee any visitors. The CPC model, on the other hand, guarantees the exact number of visitors that you pay for.
