Affiliate marketing
Encyclopedia
Affiliate marketing is a marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate's own marketing efforts. Examples include rewards sites, where users are rewarded with cash or gifts, for the completion of an offer, and the referral of others to the site.
The industry has four core players: the merchant (also known as 'retailer' or 'brand'), the network, the publisher (also known as 'the affiliate'), and the customer. The market has grown in complexity to warrant a secondary tier of players, including affiliate management agencies, super-affiliates and specialized third party vendors

Diminished compensation methods

Within more mature markets, less than one percent of traditional affiliate marketing programs today use cost per click and cost per mille. However, these compensation methods are used heavily in display advertising
Display advertising
Display advertising is a type of advertising that typically contains text , logos, photographs or other images, location maps, and similar items. In periodicals, display advertising can appear on the same page as, or on the page adjacent to, general editorial content...

 and paid search.

Cost per mille requires only that the publisher make the advertising available on his website and display it to his visitors in order to receive a commission. Pay per click requires one additional step in the conversion process to generate revenue for the publisher: A visitor must not only be made aware of the advertisement, but must also click on the advertisement to visit the advertiser's website.

Cost per click was more common in the early days of affiliate marketing, but has diminished in use over time due to click fraud
Click fraud
Click fraud is a type of Internet crime that 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 a charge per click without having actual interest in the target...

 issues very similar to the click fraud issues modern search engines are facing today. Contextual advertising programs are not considered in the statistic pertaining to diminished use of cost per click, as it is uncertain if contextual advertising can be considered affiliate marketing.

While these models have diminished in mature e-commerce and online advertising markets they are still prevalent in some more nascent industries. China is one example where Affiliate Marketing does not overtly resemble the same model in the West. With many affiliates being paid a flat "Cost Per Day" with some networks offering Cost Per Click or CPM.

Performance marketing

In the case of cost per mille
Cost Per Mille
Cost per mille , also called cost ‰ and cost per thousand , is a commonly used measurement in advertising. Radio, television, newspaper, magazine, out-of-home advertising, and online advertising can be purchased on the basis of what it costs to show the ad to one thousand viewers...

/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 can not 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.

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 targeted baselines. 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.

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

Pros and cons

Merchants favor 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 any initial setup cost). Some businesses owe much of their success to this marketing technique, a notable example being Amazon.com. Unlike display advertising

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 (see outsourced program management

, 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.

Affiliate management and program management outsourcing

Successful affiliate programs require significant work and maintenance. Having a successful affiliate program is more difficult than when such programs were just emerging. With the exception of some vertical markets, it is rare for an affiliate program to generate considerable revenue with poor management or no management ("auto-drive").

, and other unethical methods that have given affiliate marketing a negative reputation.

The increased number of Internet businesses and the increased number of people that trust the current technology enough to shop and do business online allows further maturation of affiliate marketing.

The opportunity to generate a considerable amount of profit combined with a crowded marketplace filled with competitors of equal quality and size makes it more difficult for merchants to be noticed. In this environment, however, being noticed can yield greater rewards.

Recently, the Internet marketing industry has become more advanced. In some areas online media has been rising to the sophistication of offline media, in which advertising has been largely professional and competitive. There are significantly more requirements that merchants must meet to be successful, and those requirements are becoming too burdensome for the merchant to manage successfully in-house.

An increasing number of merchants are seeking alternative options found in relatively new outsourced (affiliate) program management (OPM) companies, which are often founded by veteran affiliate managers and network program managers

  • Video Blog: Video content that allows viewers to click on and purchase products related to the video's subject.
  • File-Sharing: Web sites that host directories of music, movies, games and other software. Users upload content (usually in violation of copyright) to file-hosting sites, and then post descriptions of the material and their download links on directory sites. Uploaders are paid by the file-hosting sites based on the number of times their files are downloaded. The file-hosting sites sell premium download access to the files to the general public. The web sites that host the directory services sell advertising and do not host the files themselves.

Publisher recruitment

Affiliate networks that already have several advertisers typically also have a large pool of publishers. These publishers could be potentially recruited, and there is also an increased chance that publishers in the network apply to the program on their own, without the need for recruitment efforts by the advertiser.

Relevant websites that attract the same target audiences as the advertiser but without competing with it are potential affiliate partners as well. Vendors or existing customers can also become recruits if doing so makes sense and does not violate any laws or regulations.

Almost any website could be recruited as an affiliate publisher, but high-traffic websites are more likely interested in (for their own sake) low-risk cost per mille or medium-risk cost per click deals rather than higher-risk cost per action or revenue share deals.

Locating affiliate programs

There are three primary ways to locate affiliate programs for a target website:
  1. Affiliate program directories
    Affiliate programs directories
    Affiliate program directories are niche web directories that are very like the large and broad web directories such as the Yahoo! Directory or the Open Directory Project...

    ,
  2. Large affiliate networks that provide the platform for dozens or even hundreds of advertisers, and
  3. The target website itself. (Websites that offer an affiliate program often have a link titled "affiliate program", "affiliates", "referral program", or "webmasters"—usually in the footer or "About" section of the website.)


If the above locations do not yield information pertaining to affiliates, it may be the case that there exists a non-public affiliate program. Utilizing one of the common website correlation

 that contain rules against spam, this marketing method has historically proven to attract abuse from spammers.

E-mail spam

In the infancy of affiliate marketing, many Internet users held negative opinions due to the tendency of affiliates to use spam to promote the programs in which they were enrolled. As affiliate marketing matured, many affiliate merchants have refined their terms and conditions to prohibit affiliates from spamming.

Search engine spam

As search engines have become more prominent, some affiliate marketers have shifted from sending e-mail spam to creating automatically generated webpages that often contain product data feed
Data feed
Data feed is a mechanism for users to receive updated data from data sources. It is commonly used by real-time applications in point-to-point settings as well as on the world-wide web.

 algorithm update ("BigDaddy") in February 2006—the final stage of Google's major update ("Jagger") that began in mid-summer 2005—specifically targeted spamdexing with great success. This update thus enabled Google to remove a large amount of mostly computer-generated duplicate content from its index.

Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates". Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner

 farms, which only contain links leading to merchant sites.

Some commentators originally suggested that Affiliate links work best in the context of the information contained within the website itself. For instance, if a website contains information pertaining to publishing a website, an affiliate link leading to a merchant's Internet service provider (ISP)
Internet service provider

 within that website's content would be appropriate. If a website contains information pertaining to sports, an affiliate link leading to a sporting goods website may work well within the context of the articles and information about sports. The goal in this case is to publish quality information within the website and provide context-oriented links to related merchant's websites.

However, more recent examples exist of "thin" affiliate sites that are using the Affiliate Marketing model to create value for Consumers by offering them a service. These thin content service Affiliate fall into three categories:
  • Price comparison
  • Cause related marketing
  • Time saving

Virus and Trojan distribution through advertising networks

The implementation of affiliate marketing on the internet relies heavily on various techniques built into the design of many web-pages and web-sites, and the use of calls to external domains to track user actions (click tracking, Ad Sense) and to serve up content (advertising) to the user. Most of this activity adds time and is generally a nuisance to the casual web-surfer and is seen as visual clutter. Various countermeasures have evolved over time to prevent or eliminate the appearance of advertising when a web-page is rendered. Third party programs (Ad Aware, SpyBot, pop-up blockers, etc.) and particularly, the use of a comprehensive HOSTS file can effectively eliminate the visual clutter and the extra time and bandwidth needed to render many web pages. The use of specific entries in the HOSTS file to block these well-known and persistent marketing and click-tracking domains can also aid in reducing a system's exposure to malware by preventing the content of infected advertising or tracking servers to reach a user's web-browser.

 often uses the same methods and technologies. Merchants initially were uninformed about adware, what impact it had, and how it could damage their brands. Affiliate marketers became aware of the issue much more quickly, especially because they noticed that adware often overwrites tracking cookies, thus resulting in a decline of commissions. Affiliates not employing adware felt that it was stealing commission from them. Adware often has no valuable purpose and rarely provides any useful content to the user, who is typically unaware that such software is installed on his/her computer.

Affiliates discussed the issues in Internet forums and began to organize their efforts. They believed that the best way to address the problem was to discourage merchants from advertising via adware. Merchants that were either indifferent to or supportive of adware were exposed by affiliates, thus damaging those merchants' reputations and tarnishing their affiliate marketing efforts. Many affiliates either terminated the use of such merchants or switched to a competitor's affiliate program. Eventually, affiliate networks were also forced by merchants and affiliates to take a stand and ban certain adware publishers from their network. The result was Code of Conduct by Commission Junction

 launched its pay per click service, Google AdWords, which is responsible for the widespread use and acceptance of pay per click as an advertising channel. An increasing number of merchants engaged in pay per click advertising, either directly or via a search marketing agency, and realized that this space was already well-occupied by their affiliates. Although this situation alone created advertising channel conflicts and debates between advertisers and affiliates, the largest issue concerned affiliates bidding on advertisers names, brands, and trademarks. Several advertisers began to adjust their affiliate program terms to prohibit their affiliates from bidding on those type of keywords. Some advertisers, however, did and still do embrace this behavior, going so far as to allow, or even encourage, affiliates to bid on any term, including the advertiser's trademarks. And some affiliates abuse it by bidding on those terms by excluding the location of the advertiser alone in many Search engines.

Lack of self-regulation and collaboration

Affiliate marketing is driven by entrepreneurs who are working at the edge of Internet marketing. Affiliates are often the first to take advantage of emerging trends and technologies. The "trial and error" approach is probably the best way to describe the operation methods for affiliate marketers. This risky approach is one of the reasons why most affiliates fail or give up before they become successful "super affiliates", capable of generating US$10,000 or more per month in commission. This "frontier" life combined with the attitude found in such communities is likely the main reason why the affiliate marketing industry is unable to self-regulate beyond individual contracts between advertisers and affiliates. Affiliate marketing has experienced numerous failed attempts to create an industry organization or association of some kind that could be the initiator of regulations, standards, and guidelines for the industry. Some examples of failed regulation efforts are the Affiliate Union and iAfma.

Online forums and industry trade shows are the only means for the different members from the industry—affiliates/publishers, merchants/advertisers, affiliate networks, third-party vendors, and service providers such as outsourced program managers—to congregate at one location. Online forums are free, enable small affiliates to have a larger say, and provide anonymity. Trade shows are cost-prohibitive to small affiliates because of the high price for event passes. Larger affiliates may even be sponsored by an advertiser they promote.

Because of the anonymity of online forums, the quantitative majority of industry members are unable to create any form of legally binding rule or regulation that must be followed throughout the industry. Online forums have had very few successes as representing the majority of the affiliate marketing industry. The most recent example of such a success was the halt of the

 links on its affiliates.

Certification and training

Affiliate marketing currently lacks industry standards for training and certification. There are some training courses and seminars that result in certifications; however, the acceptance of such certifications is mostly due to the reputation of the individual or company issuing the certification. Affiliate marketing is not commonly taught in universities, and only a few college instructors work with Internet marketers to introduce the subject to students majoring in marketing.

Education occurs most often in "real life" by becoming involved and learning the details as time progresses. Although there are several books on the topic, some so-called "how-to" or "silver bullet
