Effective Cost Per Mille or eCPM (as it is often initialized to) is a phrase often used in online advertising and online marketing circles. It means the cost of every 1,000 ad impressions shown.

CPM is considered the optimal form of selling online advertising from the publisher’s point of view. A publisher gets paid every time an ad is shown.

eCPM is used to measure the effectiveness of a publisher’s inventory being sold (by the publisher) via a CPA, CPC, or CPT basis. In other words, the eCPM tells the publisher what they would have received if they sold the advertising inventory on a CPM basis (instead of a CPA, CPC, or CPT basis).

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.

Click fraud occurs in pay per click online advertising when a person, automated script or computer program imitates a legitimate user of a web browser clicking on an ad, for the purpose of generating an improper charge per click. Click fraud is the subject of some controversy and increasing litigation due to the advertising networks being a key beneficiary of the fraud whether they like it or not.

Use of a computer to commit this type of fraud is a felony in many jurisdictions, for example as covered by Penal code 502 in California and the Computer Misuse Act 1990 in the United Kingdom. There have been arrests relating to click fraud with regard to malicious clicking in order to deplete a competitor’s advertising budget.

In 2004, a California man created a software program that he claimed could let spammers defraud Google out of millions of dollars in fraudulent clicks. Authorities said he was arrested while trying to blackmail Google for $150,000 to hand over the program.

The display advertising portion of online advertising is increasingly dominated by rich media, generally using Adobe Flash. Rich media advertising techniques make overt use of color, imagery, page layout, and other elements in order to attract the reader’s attention. Some users might consider these ads as intrusive or obnoxious, because they can distract from the desired content of a webpage. Some examples of common rich media formats and the terms of art used within the industry to describe them:

• Interstitial or Expanding ad: The display of a page of ads before the requested content.
• Floating ad: An ad which moves across the user’s screen or floats above the content.
• Expanding ad: An ad which changes size and which may alter the contents of the webpage.
• Polite ad or Polite download: A method by which a large ad will be downloaded in smaller pieces to minimize the disruption of the content being viewed
• Wallpaper ad: An ad which changes the background of the page being viewed.

In addition, ads containing streaming video or streaming audio are becoming very popular with advertisers.

Because of the ability to track results of online advertising at a more granular level than what is available through traditional advertising, varying ways have developed for the advertisers and publishers to do business. The three most common ways in which online advertising is purchased are CPA, CPC, and CPM.

CPA (Cost Per Action) 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 only pays for the media on the basis of the number of users who complete a transaction, such as a purchase or sign-up.

CPC (Cost Per Click) advertising is also performance based and is common in search marketing, where it is often known as Pay per click (PPC). In this scheme, an advertisement may be displayed (and assumedly viewed) many times, but the advertiser only pays based on the number of user clicks. This system provides an incentive for publishers to target ads correctly (often by keyword), as the payment depends upon the ad not only being seen, but the viewer responding and following the hyperlink.

CPM (Cost per Thousand) advertising is the most common basis in the business and is used for most display advertising and rich media. This scheme most closely resembles offline advertising, wherein the advertiser is paying for exposure of their message to a specific audience. CPM costs are priced per thousand, so that a $1 CPM, means that the advertiser pays $1 for every thousand impressions.

A significant number of firms, from small businesses to multinational corporations, incorporate online advertising into their marketing strategy. This is even true of firms which conduct their business through more traditional brick and mortar channels. In response to this demand, a number of firms specialize in facilitating online marketing. Therefore, online advertisements typically involve at least two separate firms: the advertiser or agency which purchases or sponsors the advertisement and the publisher or network which distributes the ad for display. Additional parties may also be included, such as an ad serving technology provider, a third party sales network, or other combinations.

In capitalizing on the increasing importance of the Internet as a marketing medium, the online advertising industry has developed specialized technical systems to manage the ways ads are distributed and viewership totaled. The Internet Advertising Bureau (IAB) has established guidelines for the counting methodology, size requirements, and other aspects of the business.

Because of the close relation between technical innovation and online advertising, many firms specialize in both. For example, most search engines couple their search service with an advertising program, exploiting the benefits of keyword-based search technology by including ads in search results. Many technology firms specialize in ad serving, the systems used to select the ads to show, optimize results, and generate reports.

Email advertising

Legitimate Email advertising is often known as opt-in email to distinguish it from spam.

Affiliate marketing

Affiliate marketing is a form of advertising where the advertiser allows a potentially large number of small publishers to pick specific creative elements or offers to market in exchange for payment should such marketing create sales or other revenue. This is usually accomplished though a self-service online system, such as those offered by third parties Performics, BeFree, CommissionJunction, or Linkshare. Affiliate marketing was an early innovation of online retailer Amazon, which has used its program to generate enormous volumes of low cost brand exposure.

Contextual advertising

Many advertising networks display text-only ads that correspond to the keywords of an Internet search or to the content of the page on which the ad is shown. These ads are believed to have a greater chance of attracting a user, because they tend to share a similar context as the user’s search query. For example, a search query for “flowers” might return an advertisement for a florist’s website.

Another newer technique is embedding keyword hyperlinks in a webpage which are sponsored by an advertiser. When a user follows the link, they are sent to a sponsor’s website.

Ads and malware

There is also class of advertising methods which may be considered unethical and perhaps even illegal. These include external applications which alter system settings (such as a browser’s home page), spawn pop-ups, and insert advertisements into non-affiliated webpages. Such applications are usually labeled as spyware or adware. They may mask their questionable activities by performing a simple service, such as displaying the weather or providing a search bar. Some programs are effectively trojans. These applications are commonly designed so as to be difficult to remove or uninstall. The ever-increasing audience of online users, many of which are not computer-savvy, frequently lack the knowledge and technical ability to protect themselves from these programs.

Click-through rate or CTR is a way of measuring the success of an online advertising campaign. A CTR is obtained by dividing the number of users who clicked on an ad on a web page by the number of times the ad was delivered (impressions). For example, if your banner ad was delivered 100 times (impressions delivered) and 1 person clicked on it (clicks recorded), then the resulting CTR would be 1%.

Banner ad click-through rates have fallen over time, often measuring significantly less than 1%. By selecting an appropriate advertising site with high affinity (e.g. a movie magazine for a movie advertisement), the same banner can achieve a substantially higher click-through rate. Personalized ads, unusual formats, and more obtrusive ads typically have higher click-through rates than standard banner ads.

Cost Per Click or CPC (as it is often initialized to) is a phrase often used in online advertising and online marketing circles.

With many advertising networks and websites, the advertiser is charged for advertising their ad (on the advertising network or website) only when a user clicks on their ad. How much they pay (for that click) is called their Cost Per Click or CPC.

The CPC can be determined by different factors, depending on which advertising network or website the advertiser is advertising on.

Other common forms, of charging for advertising, include:

• CPM
• CPA
• CPT

Effective Cost Per Action (often abbreviated to eCPA) is a phrase often used in online advertising and online marketing circles.

CPA is considered the optimal form of buying online advertising from the advertiser’s point of view, as they only pay for an advert when an action has occurred. An action can be a product being purchased, a form being filled, etc. (The desired action to be performed is determined by the advertiser.)

eCPA is used to measure the effectiveness of advertising inventory purchased (by the advertiser) via a CPC, CPM, or CPT basis. In other words, the eCPA tells the advertiser what they would have paid if they purchased the advertising inventory on a CPA basis (instead of a CPC, CPM, or CPT basis).
