Affiliate Marketing: A comprehensive guide

How Affiliate Marketing Works

This comprehensive guide will give a rundown of the history and benefits of affiliate marketing as part of your online marketing media mix.

Have you ever wondered why there are so many websites and organizations that go out of their way to write reviews and give you facts about a product or service?

The chances are they are not doing it out of the goodness of their heart, nor for the betterment of the Internet or to objectively help in the purchase-making process of the average consumer. 

If we look closely, more than likely we will find that the review site is an affiliate of the brand which they are reviewing and they’re using the review to sell the product.

 The Early Days of Affiliate Marketing

It’s said that affiliate marketing began as a concept by William J. Tobin in the late 1980s where his company would drive traffic from consumers looking to send flowers to loved ones etc. In simple terms, he didn’t own a flower shop or distribution service, but he was able to put an arrangement and framework together which meant that he would be able to send interested consumers to other companies to buy flowers and he would earn a commission for the sale.

While affiliate marketing has gotten more advanced and complicated in terms of audience profiling and communications, the basic premise of it remains the same – affiliates send consumers to other brand websites and if the consumer purchases the product, the affiliate gets a commission in return for generating the sale.

As the effectiveness of affiliate marketing grew for both advertisers and affiliates, larger companies started to get on board with the idea. The most notable early adopter was Amazon, which launched its Associate’s Program in 1996. This program allowed anyone to sign up and put links to Amazon products on their website, these links were tagged up with identifiers and if a sale occurred as a result of the affiliate sending traffic to Amazon, the affiliate got a commission (and Amazon got a sale).

The next major development in affiliate marketing happened in the late 1990s with the launch of two major affiliate networks, ClickBank and Commission Junction, which has since been rebranded as CJ Affiliate by Conversant. These networks allowed small businesses, who might not have the resources to launch their own affiliate program, to get access to affiliates and use them to generate additional sales.

Despite the fact that affiliate marketing has been around for some 30 years and has generated billions in revenue for some of the biggest brands, most people are still unsure what exactly it is.

The next sections will look at the elements of an affiliate marketing program, and how they can be implemented and optimized, so you can consider using them as part of your marketing mix, or indeed becoming an affiliate yourself.

The Basic Elements of Affiliate Marketing

For most affiliate programs, there are four stakeholders:

1. The advertiser: This is the brand or company that wants to sell a product or service.

2. The affiliate or publisher*: The website that drives traffic to the advertiser’s website.

3. The affiliate network: In simple terms, this is the software that tracks traffic and sales.

4. The consumer: The person who visits the affiliate’s website, clicks a link or banner and buys the product from the advertiser.

How Do You Set Up an Affiliate Program?

While you can create your own purpose-built tracking software (if you have such a requirement, and loads of cash to put into software development and time to sign up the affiliates), most often this isn’t the most efficient way to proceed. The best way to explain how to set up a program is to go through an affiliate network.

Choose Your Network

Firstly, you need to choose what network you want to go with. This can be down to their fees, the type of affiliates they have on their books, creative/banner capabilities and how/when they pay out on commissions. Once you have decided on your network and opened an account, you must set up the terms for affiliates – in most cases, your affiliate network account manager will help with this.

The terms of an affiliate program include things like:

  • commissions paid for sales,
  • types of sales which are considered valid for commission,
  • different commission rates for different products,
  • your brand guidelines, and
  • pay-per-click (PPC) advertising to drive traffic for people looking for your brand.

Affiliate marketing is most utilized in eCommerce as there is a simple payment methodology for the affiliates, as the transaction happens online and commissions are easily calculated.

How Does an Affiliate Program Work?

As an advertiser, now that you have a product to sell, there are a load of websites (affiliates) willing to send traffic your way, you need to be able to quantify the sales from the program and pay the affiliates for their efforts.

Tracking the performance of a program is done by adding tracking parameters to the URL links on the affiliate’s website. These parameters are created automatically by the affiliate network and given to the affiliates – if the affiliates want to be paid for the sales they drive, the affiliate will add these tracking parameters to every URL on their website that links to your website.

Similar to adding Google Analytics code, the advertiser must also add a tracking code or pixel (from the affiliate network) to the HTML of their website. This means that every time someone clicks a link, it is tracked by the affiliate’s URL tracking parameter talking to the pixel code on your website, and if a sale occurs on your website this sale is attributed to the affiliate as they drove the traffic.

Furthermore, the value of the transaction is counted by the affiliate network and you will pay a commission on this to the affiliate.

If the terms of your affiliate program state that you will pay 2.2% of the value of the transaction to the affiliates, that is the commission you pay. This is what’s called cost per acquisition (CPA) pricing – you only pay affiliates if they generate a sale (unlike PPC where you have to pay for the click regardless of whether it generates a sale or not).

This pricing model is what makes affiliate marketing so attractive to advertisers. There is a reduced risk of media spending as you are only paying when you sell something. 

The key is to understand what the optimum commission rate is to make the program profitable for the advertiser, and attractive for affiliates to want to work with the advertiser.

Affiliates won’t want to give premium positions on their website to a product or spend a lot of time and money writing reviews and creating content, for a program that doesn’t reward them for their efforts, so you have to make it worth their while.

How Do Affiliates Drive Traffic That Converts?

Content Marketing International CertificateWe know that affiliates add tracking parameters to links on their website which can track sales and traffic that they have driven to the advertiser’s website, but why would people click those links in the first place?

In most cases, affiliates do things like write a review of a computer or game, and then at the end of the article or review, there is a link to buy the product.

Many of these reviews appear as lists, e.g. ‘Top 10 Mobile Phone Buys for 2023’. So what appears to be a legitimate review can be geared towards driving sales of those products, and the more sales that occur the more commission the affiliate earns.

Essentially, advertisers are borrowing some of the credibility of the affiliate’s brand to drive additional traffic which might convert.

This is quite evident in the financial services and travel sectors. Destination review sites such as TripAdvisor, Kayak etc. get significant commissions from advertisers, so they write reviews about a destination, promote the review on their newsletter, social media or through organic search and will include links to hotels, transport, flights, insurance etc. within the review.

This way, consumers get to have a third-party review of a product, service or destination, and then hopefully they click through to the brand’s website and buy.

In short, the consumer gets a view of something they are interested in which leads to a sale for the advertiser and a commission payment for the affiliate who helped push the consumer through the funnel.

How to Optimize an Affiliate Program

Advertisers can encourage affiliates to drive more traffic by offering higher percentage commissions, sometimes for short periods of time. This can be quite common during sale periods.

If the affiliate knows they can earn more commission, they will place advertiser links in premium locations on their website and promote it harder using their own channels. All of this should encourage more sales for the advertiser.

Many networks allow advertisers to upload their creative banners to the network and this will be served on the affiliate’s websites alongside reviews and other content. All of this can drive sales for the Advertiser and commissions for the affiliate.

Role of Influencers in Affiliate Marketing

The emergence of influencers has been a significant development in the world of affiliate marketing. Many of the links from influencers’ social accounts, newsletters and other sources will in fact be affiliate links. This is how the influencer gets paid for promoting a product. They create content, push their audience to buy the product, and drive a click, so when a sale occurs it’s tracked using affiliate links and the influencer gets a commission.

However, a game-changing development in affiliate marketing was the implementation of the General Data Protection Regulation (GDPR) by the EU in May 2018. Prior to this, affiliate networks had amassed very detailed persona data and profiles to drive sales for advertisers, but in an instant, this technique was no longer as viable as pre-GDPR. Many of the networks have adapted to the change though.

Summary About the Affiliate Marketing

Affiliate Marketing ComponentsAffiliate marketing is a useful channel to include in your media mix if you are an eCommerce advertiser.

You can access thousands of affiliates who will drive traffic and sales for you using affiliate networks. It tends to represent 1%-5% of your overall eCommerce transactions, so it can drive incremental sales to your bottom line if done correctly.

As it’s a commission-based payment system, there is a risk of fraud, i.e. affiliates sending through invalid sales which they expect to be paid for, however, most networks are very good at identifying fraud and you won’t have to pay.

Affiliate marketing can be time-consuming in terms of managing creativity and payments so it’s important to keep it as simple as possible to justify and understand the return on investment.

There are a lot of emerging opportunities for both advertisers and publishers (affiliates) as the dynamics of online commerce develop and people look to third-party recommendations before purchasing across a variety of industry verticals.
