Cost Per Impression 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 CPA basis.)

The Cost Per Impression is often measured using the CPM (Cost Per Mille) metric. (A CPM is the cost of one thousand (1,000) impressions.)

CPM is considered the optimal form of selling online advertising from the publisher’s point of view. A publisher gets paid for each ad that is shown.

This type of advertising arrangement closely resembles Television and Print Advertising Methods for speculating the cost of an Advertisement. With Television the Nielsen Ratings are used and Print is based on how many readers a publication has. For a Website the numbers are a bit more exact due to the TCP/IP nature of the Internet.

CPM and/or Flat rate advertising deals are preferred by the Publisher/Webmaster because they will get paid regardless of any action taken.

For Advertisers a Performance Based system is preferred. There are two methods for Paying for Performance: 1) CPA – Cost per Action/Acquisition and 2) CPC – Cost per Click Through.

Today, it is very common for large publishers to charge for most of their advertising inventory on a CPM or CPT basis.

A related term, eCPM or effective Cost Per Mille, is used to measure the effectiveness of advertising inventory sold (by the publisher) via a CPC, CPA, or CPT basis.

Cost Per Mille

The initialization CPM comes from print world (and is a latin word), and stands for Cost Per Mille in the US or, more correctly, in the UK Cost Per M, with M representing the Roman numeral for thousand. When online advertising started gaining momentum, those in the industry used this term (rather than something like CPI) as a metric for describing the Cost Per Impression largely because advertisers were already familiar with the term CPM.

It is important to remember that when someone says something like, “our CPM is $5″. That this means that the Cost Per Impressions is $0.005 — half a cent.

Brands in the field of marketing originated in the 19th century with the advent of packaged goods. Industrialization moved the production of many household items, such as soap, from local communities to centralized factories. When shipping their items, the factories would literally brand their logo or insignia on the barrels used, which is where the term comes from.

These factories, generating mass-produced goods, needed to sell their products to a wider market, to a customer base familiar only with local goods. It quickly became apparent that a generic package of soap had difficulty competing with familiar, local products. The packaged goods manufacturers needed to convince the market that the public could place just as much trust in the non-local product.

Around 1900, James Walter Thompson published a house ad explaining trademark advertising. This was an early commercial explanation of what we now know as branding.

Many brands of that era, such as Uncle Ben’s rice and Kellogg’s breakfast cereal furnish illustrations of the problem. The manufacturers wanted their products to appear and feel as familiar as the local farmers’ produce. From there, with the help of advertising, manufacturers quickly learned to associate other kinds of brand values, such as youthfulness, fun or luxury, with their products. This kickstarted the practice we now know as branding.

Modern branding practices are studied and analyzed at research institutes such as the Zyman Institute of Brand Science at the Goizueta Business School at Emory University.

Litigation

Disputes over the issue have resulted in a number of lawsuits. In one case, Google (acting as both an advertiser and advertising network) won a lawsuit against a Texas company called Auction Experts (acting as a publisher), which Google accused of paying people to click on ads that appeared on Auction Experts’ site, costing advertisers $50,000[1]. Despite networks’ efforts to stop it, publishers are suspicious of the motives of the advertising networks, because the advertising network receives money for each click, even if it is fraudulent.

Solutions

Proving click fraud can be very difficult, since it is hard to know who is behind a computer and what their intentions are. Often, the best an advertising network can do is to identify which clicks are most likely fraudulent, and not charge the account of the advertiser. Ever more sophisticated means of detection are used, but none are foolproof.

The pay-per-click industry is lobbying for tighter laws on the issue. Many hope to have laws that will cover those not bound by contracts.

A number of companies are developing viable solutions for click fraud identification and are developing intermediary relationships with advertising networks. Such solutions fall into two categories:

a) Forensic analysis of advertisers’ web server log files

This analysis of the advertiser’s web server data requires an in-depth look at the source and behavior of the traffic. As industry standard log files are used for the analysis, the data is verifiable by advertising networks.

b) Third-party corroboration

Third parties offer web-based solutions that might involve placement of single-pixel images or Javascript on the advertiser’s web pages and suitable tagging of the ads. The visitor may be presented with a cookie. Visitor information is then collected in a third-party data store and made available for download. The better offerings make it easy to highlight suspicious clicks and they show the reasons for such a conclusion. Since an advertiser’s log files can be tampered with, their accompaniment with corroborating data from a third party forms a more convincing body of evidence to present to the advertising network.
