Affiliate programs have truly grown over
the last year and a half to become perhaps one of the Internet's
premier business models. However, over this time, I've received
many requests for assistance from visitors new to affiliate programs,
that aren't familiar with all of the concepts and terms involved.
Naturally, this can make it difficult to properly evaluate the hundreds
of programs out there and decide which are best for you.
I would like to cover some of the basics,
and define some of the common terms that are used when discussing
affiliate programs. For those of you new to affiliate programs this
guide should help you quickly get up to speed on how affiliate programs
can make an excellent, and profitable, addition to your web site.
Here are some of the more common affiliate program terms you'll
likely run in to, and their basic definitions:
Affiliate: An independent party
that promotes the products or services of a merchant in exchange
for a commission. Also an associate, partner, reseller, or referral
partner.
Merchant: A company that has set
up an affiliate program and has agreed to share a commission with
affiliates who promote their web site, products and/or services.
Also termed an advertiser, vendor, or simply referred to as an "affiliate
program."
Commission: The income you receive
for generating a sale, lead or click-through to a merchant's web
site. Sometimes called a referral fee, a finder's fee or a bounty.
Affiliate Program: Used in a broad
sense, an affiliate program is any type of revenue sharing program
where an affiliate web site receives a portion of income for delivering
sales, leads, or traffic to a merchant web site. In a narrow sense,
affiliate programs are commonly considered those programs that use
a pay- per-sale model like our own. Also termed associate, partner,
referral, reseller, or sponsor programs.
Pay-Per-Sale: A program where
you receive a commission for each sale of a product or service that
you refer to a merchant's web site. Pay-per-sale programs usually
offer the highest commissions and the lowest conversion ratio. Also
referred to as Cost-per- Action (CPA for short) and generically
as an Affiliate Program.
Pay-Per-Lead: A program where
you receive a commission for each sales lead that you generate for
a merchant web site. Examples would include completed surveys, contest
or sweepstakes entries, downloaded software demos, or free trials.
Pay-per-lead generally offers midrange commissions and midrange
to high conversion ratios (since visitor purchases are not required
for you to be able to earn a commission). Like pay-per-sale, pay-per-lead
is also referred to as a Cost-per-Action or CPA for short.
Pay-Per-Click: A program where
you receive a commission for each click (visitor) you refer to a
merchant's web site. Pay-per-click programs generally offer some
of the lowest commissions (from $0.01 to $0.25 per click), and a
very high conversion ratio since visitors need only click on a link
to earn you a commission.
Pay-Per-Impression: A program
where you receive a commission each time that a merchant's ad or
link is displayed on your site. Pay- per-impression generally offers
the lowest commissions, but a nearly 100% conversion ratio since
a visitor merely has to view the ad to earn you a commission --
and this often results in the highest earnings potential. Pay-per-impression
programs are generally measured in CPMs (see below) and form the
standard of banner advertising for larger web sites.
Conversion Ratio: The ratio of
visitors from your site that are "converted" into a sale, lead or
click, and go on to earn the you a commission. A conversion ratio
of 5% would mean that for every 100 visitors to your site, 5 would
click-through, complete an action and earn you a commission. Many
factors will influence the conversion ratio, including how targeted
the affiliate program's products are to your visitor's interests,
the price and value of the products being promoted, the merchant's
ability to track all sales, and the overall effectiveness of the
merchant's web site.
Click-Through Ratio: The percentage
of visitors who click-through on a link to visit the merchant's
web site. Higher click-throughs are preferable although not always
a great measure of success. Pay-per-click earnings are highly dependent
on the click-through ratios. Click-through ratios can often be improved
through a variety of means: by making links more visible to visitors,
adding personal comments or testimonials about the product, or even
reducing the number of links a visitor can follow.
CPM: The practice of calculating
a cost per 1000 ad displays. It is used by programs that pay on
an impression basis -- with the CPM rate being the amount you earn
for every 1000 times an advertisement is displayed. For example,
a $5 CPM means you earn $5 every time 1000 ads are displayed on
your site. CPM can also be calculated for pay-per-sale, pay-per-lead
and pay-per-click programs by using this formula:
Amount earned / (number of impressions/1000)
Calculating the CPM of affiliate programs
can be an effective means of comparing the results over time from
various programs -- allowing you to put more emphasis on the strong
programs, and dropping the poorly performing programs.
Two-tier Commission: Two-tier,
or multi-tier, refers to the practice of a merchant paying commissions
to both the affiliate that referred a sale, lead or click, and the
affiliate that referred that affiliate to the program. A descendent
of network marketing, two-tier programs are generally quite legitimate
and offer the merchant an effective means to promote their affiliate
program quickly. However, be wary of any programs that try to charge
startup or membership fees to join. These programs should be avoided,
as there are hundreds of others that do not charge to become an
affiliate. Some are simply pyramid schemes in disguise.
Residual Commission: Residual
commissions refer to programs that provide affiliates the ability
to earn an income, month after month, for referring a sale to a
merchant. They are usually those that offer some type of service
for which the customer is charged an ongoing subscription fee. Examples
include web hosting, tele- communications, and ecommerce solutions.
They offer an effective benefit to affiliates since the affiliate
can earn income for an extended period, perhaps even years, from
a single sale.
Tracking Method: Tracking refers
to the way that a program tracks referred sales, leads or clicks.
The most common are by using a unique web address (URL) for each
affiliate, or by embedding an affiliate ID number into the link
that is processed by the merchant's software. Some programs also
use cookies for tracking.
Cookies: Cookies are small files
stored on the visitor's computer which record information that is
of interest to the merchant site. Despite concerns that some people
have, cookies are in no way dangerous -- and can not be used to
steal names, email addresses, phone or credit card numbers. With
affiliate programs, cookies have two primary functions: to keep
track of what a customer purchases, and to track which affiliate
was responsible for generating the sale (and is due a commission).
Be especially wary of programs that only
use cookies since they have many inherent limitations: the user
can turn them off, they expire after a certain date or time, and
they can be deleted off the visitor's computer. Most programs use
either unique URLs or affiliate ID numbers in conjunction with cookies
to track properly. Cookies can then be used to give the affiliate
credit at a later time of purchase, even if the visitor returns
to the merchant's site as opposed to the affiliate's unique URL.
Banner Networks: A whole bunch
of networks have popped up to better facilitate the pay-per-click
concept. Most pay-per-click programs are part of a network where
the network acts as middle- man between the actual advertisers and
the affiliates which run the ads. And for this service, the network
takes a percentage of the overall revenues. Some larger networks
include:
- http://www.eads.com/,
- http://www.teknosurf.com/,
- http://www.valueclick.com/,
and
- http://www.clickagents.com/.
Third-party Administrators: Similar
to banner networks, an increasing number of companies have sprouted
up to help merchants facilitate their affiliate programs. Most act
as consultants and software providers to merchants, and thus allow
them to cost- effectively outsource their affiliate program operations.
For affiliates, the networks often offer simplified registration,
standardized commission tracking and reporting, and even consolidated
commission payments. Some leading third-party affiliate program
administrators include:
