Affiliate ProgramsThe concept of an Affiliate Program is nothing new and the method of paying commission for referrals predates the emergence of the Internet. However the sheer speed of connections between potential consumer, affiliate and online vendor makes this space a valuable and lucrative marketing and income-generating resource to many. According to MarketingSherpa, in 2006 $6.5 billion US was earned online by affiliates across a broad variety of verticals worldwide.
Technically speaking, affiliate programs could include all of the below employed online advertising methods, as each pays a sum for referrals made. One main difference between the methods lie in where the revenue earned/paid is derived from. Depending on the method it could be a bulk payment per distribution, CPS (cost per sale) or a rev-share model, CPA (cost per action), CPC (cost per click) or CPM (cost per mille), among other lesser popular methods. Let’s talk a little about what these revenue sharing models look like.
Payment per distribution
In methods such as Email Marketing, E-Zine Marketing or sponsored articles, websites or preview pages, sometimes there is a bulk sponsorship payment requested by the distributor. Often depending on certain statistics such as page views or subscription/distribution list size and quality, a lump sum for one or multiple ad slots (via graphic banners, buttons, company descriptions or sponsored editorials or articles) is required prior to dissemination. The advantage to this type of method for the advertiser is that there is very little leg work or calculation required aside from content and graphic requirements and production. The advantage for the distributor/affiliate is that it’s a one-time action resulting in a bulk payment, not a result-driven revenue model. The disadvantages could involve the difficult to predict ad/editorial performance and ROI.
Cost Per Action (CPA, or Pay Per Action (PPA))
CPA is a broad term used to define when an advertiser compensates their ad host based on a particular action generated, such as a purchase, a subscription or a form submission. The advantage to advertisers here is that they only need to pay when their desired action has taken place, meaning they can define what is that they desire greatest to occur and set their budgets accordingly. For example, when an ad is hosted on a website CPA here could mean that the advertiser only pays when a sale has been completed via this specific ad. This is most effective when buying advertising.
Note: sometimes CPA is used to refer Cost Per Acquisition. In this sense, CPA means that the advertiser pays based on the desired acquisition being received, such as a form submission or sale. As at all times Cost Per Acquisition can fall under the definition of Cost Per Action, the opposite cannot be said to be true so it is important to understand the difference.
Cost Per Sale (CPS) / Revenue Sharing
One of the most popular methods of earning income online is via a rev-share model, or CPS. Here, online vendors pay their partners or affiliates a percentage of their revenue generated from sales in exchange for the original referral. This is a very simple and effective method as there is very little calculation involved aside from agreeing upon a fair compensation percentage.
Cost Per Click (CPC)
This is probably one of the most well-known revenue generating ad models. CPC refers to the amount of money paid by an advertiser to their ad host for the number of clicks generated by the hosted advertisement. As a whole, this method is referred to as a PPC model, or Pay Per Click, meaning the advertiser pays their ad host based on the number of clicks generated through the ad. This term is closely linked to search engine marketing, where advertisers bid on keyword phrases that closely match their target market. Here, often the CPC depends on the search network used and the amount of popularity/competition for the desired keyword phrase. However this changes outside of the search marketing world where the advertiser does not use a bidding model. The advantage here is that you have a targeted audience that is encouraged to click based on relevant environment with which they are surfing. Additionally, for the ad host the advantage is that they generate revenue whether or not an action other than the click is made.
Cost Per Mille (CPM)
As in Latin, “mille” means thousand, this term technically means cost per thousand. As such, CPM is a measurement used to quantify the value of 1000 impressions of an ad, and helps define the relative cost of an advertising campaign. So a set amount of money is paid per thousand of ad impressions shown. As with CPC, the advantage to the ad host is that they are paid whether or not a sale is generated.
Hope these quick and dirty definitions help clarify anything with those confusing and similar abbreviations. Anything to add? Or should I say… ATA?
