==Overview==

The CPM (also sometimes referred to as CPI) advertising campaign model used for website banners, text links, e-mail marketing, and opt-in e-mail advertising. However, the opt-in e-mail advertising is generally charged on a [[CPA]] (Cost Per Action) basis. The CPM model, along with other fixed rate advertising deals, are often preferred by webmasters since the payment is done each time the advertisement is viewed; thus, the payment is generally greater than other advertising models.
