Cost Per Impression – (CPI)
Cost per Impression (CPI) is a phrase often used in online advertising and marketing, related to web traffic. It is used for measuring the worth and cost of a specific e- marketing campaign. This technique is applied with web banners, text links, e- mail spam and opt- in – e- mail advertising, although opt-in e-mail advertising is more commonly charged on a Cost Per Action basis.
The Cost per Impression is often abbreviated to CPI
This type of advertising arrangement closely resembles Television and Print Advertising Methods for speculating the cost of an Advertisement. Often, industry agreed approximates are used. With Television the Nielsen Ratings are used and for Print, it's the circulation a publication has.
For Online Advertising, the numbers of views can be a lot more precise. When a user requests a Web Page, the originating server creates a log entry. Also, a third party tracker can be placed in the web page to verify how many accesses that page has had.
There are other advertising pricing structures too, including Cost per Click Through, - Cost per Lead (lead usually meaning a free registration) and Cost per Sale. These structures are collectively referred to as CPA - Cost per Action.
CPI deals are s preferred by the Webmaster because they will receive a more consistent fee proportional to the amount of traffic generated
