Revenue models:The three most common ways in which online advertising is purchased are CPM, CPC, and CPA.
CPM (Cost Per Mille), also called "Cost Per Thousand impressions (CPT), is where advertisers pay for exposure of their message to a specific audience. "Per mille" means per thousand impressions, or loads of an advertisement. However, some impressions may not be counted, such as a reload or internal user action.
CPV (Cost Per Visitor) is where advertisers pay for the delivery of a Targeted Visitor to the advertisers website.
CPV (Cost Per View) is when an advertiser pays for each unique user view of an advertisement or website (usually used with pop-ups, pop-unders and interstitial ads).
CPC (Cost Per Click) is also known as Pay per click (PPC). Advertisers pay each time a user clicks on their listing and is redirected to their website. They do not actually pay for the listing, but only when the listing is clicked on. This system allows advertising specialists to refine searches and gain information about their market. Under the Pay per click pricing system, advertisers pay for the right to be listed under a series of target rich words that direct relevant traffic to their website, and pay only when someone clicks on their listing which links directly to their website. CPC differs from CPV in that each click is paid for regardless of whether the user makes it to the target site.
CPA (Cost Per Action) or (Cost Per Acquisition) advertising is performance based and is common in the affiliate marketing sector of the business. In this payment scheme, the publisher takes all the risk of running the ad, and the advertiser pays only for the amount of users who complete a transaction, such as a purchase or sign-up. This model ignores any inefficiency in the sellers web site conversion funnel.
CPL (Cost Per Lead) advertising is identical to CPA advertising and is based on the user completing a form, registering for a newsletter or some other action that the merchant feels will lead to a sale.
CPO (Cost Per Order) advertising is based on each time an order is transacted.
CPE (Cost Per Engagement) is a form of Cost Per Action pricing first introduced in March 2008. Differing from cost-per-impression or cost-per-click models, a CPE model means advertising impressions are free and advertisers pay only when a user engages with their specific ad unit. Engagement is defined as a user interacting with an ad in any number of ways.
