Performance or Affiliate Marketing

Affiliate marketing is also called "performance marketing", in reference to how sales employees are typically being compensated. Such employees are typically paid a commission for each sale they close, and sometimes are paid performance incentives for exceeding objectives. Affiliates are not employed by the advertiser whose products or services they promote, but the compensation models applied to affiliate marketing are very similar to the ones used for people in the advertisers' internal sales department.

The phrase, "Affiliates are an extended sales force for your business", which is often used to explain affiliate marketing, is not completely accurate. The primary difference between the two is that affiliate marketers provide little if any influence on a possible prospect in the conversion process once that prospect is directed to the advertiser's website. The sales team of the advertiser, however, does have the control and influence up to the point where the prospect signs the contract or completes the purchase. In the case of cost per mille/click, the publisher is not concerned about a visitor being a member of the audience that the advertiser tries to attract and is able to convert, because at this point the publisher has already earned his commission. This leaves the greater, and, in case of cost per mille, the full risk and loss (if the visitor cannot be converted) to the advertiser.

Cost per action/sale methods require that referred visitors do more than visit the advertiser's website before the affiliate receives commission. The advertiser must convert that visitor first. It is in the best interest for the affiliate to send the most closely targeted traffic to the advertiser as possible to increase the chance of a conversion. The risk and loss is shared between the affiliate and the advertiser.

Multi-tier Programs

Some advertisers offer multi-tier programs that distribute commission into a hierarchical referral network of sign-ups and sub-partners. In practical terms, publisher "A" signs up to the program with an advertiser and gets rewarded for the agreed activity conducted by a referred visitor. If publisher "A" attracts publishers "B" and "C" to sign up for the same program using his sign-up code, all future activities performed by publishers "B" and "C" will result in additional commission (at a lower rate) for publisher "A".

Two-tier programs exist in the minority of affiliate programs; most are simply one-tier. Referral programs beyond two-tier resemble multi-level marketing (MLM) or network marketing but are different: Multi-level marketing (MLM) or network marketing associations tend to have more complex commission requirements/qualifications than standard affiliate programs.

Pros and Cons from the Advertiser's Perspective

Merchants favour affiliate marketing because in most cases it uses a "pay for performance" model, meaning that the merchant does not incur a marketing expense unless results are accrued (excluding of course, any initial setup costs). Some businesses owe much of their success to this marketing technique, a notable example being Amazon.com.

Implementation Options

Some merchants run their own (in-house) affiliate programs using popular software while others use third-party services provided by intermediaries to track traffic or sales that are referred from affiliates.  Merchants can choose from two different types of affiliate management solutions: standalone software or hosted services, typically called affiliate networks. Payouts to affiliates or publishers are either made by the networks on behalf of the merchant, by the network, consolidated across all merchants where the publisher has a relationship with and earned commissions or directly by the merchant itself.
