Definition

Affiliate marketing is an advertising/marketing model in which a company or product owner pays a commission to third-party publishers/marketers to generate traffic, leads, or sales for the product owner's or company's products and services.
Affiliate marketing helps business owners increase sales by allowing external individuals to recommend their products in exchange for a commission, and it is handled mostly by an affiliate platform.

Now that you know the basic definition of affiliate marketing, we will dive deeper into this topic.
We will walk you through all you need to know about affiliate marketing, some examples of affiliate marketing platforms, and also how you can become an affiliate marketer and start earning money online.

How Does Affiliate Marketing Work?

A complete affiliate marketing setup requires four parties: the Product Owner (Vendor or Merchant), the Promoter (Affiliate Marketer), the Product Buyer (Consumer), and the Platform.

The Product Owner (Vendor): The owner of the product that is being marketed. They specialize in creating products and services. And this could be an individual or a company.

The Promoter (Affiliate Marketer): The person responsible for promoting the product owned by a known or unknown vendor/company. This party earns a commission on any sale(s) they make on a particular product or service. Therefore, they require a way to promote those products, and without one, they may never make any money for themselves.
The reason why some people seem to make money quickly in affiliate marketing is that some of them already have customers or audiences, which helps them sell products very quickly.

The Product Buyer: This is the customer who buys the product or service promoted by the affiliate marketer. This is the party that completes the transaction. Basically, without this party, there would be no money to be shared.

The Platform: This is the place where the Product Owner (Vendor) lists their product so that a Promoter (Affiliate Marketer) can pick it and promote it. This party handles the analytics; they organize the platform to benefit both the Promoter and the Vendor. They keep track of the product owner, the product being sold, the price and quantity, as well as the person who sold the product.

Some vendors/product owners manage their own affiliate networks, thereby excluding any external platform. It is always the best option to start your affiliate marketing through a platform — with this, you may never have an unrecorded sale, and you will also be open to a wider audience, more products, and more marketers.
When you sign up for an affiliate site, there are always two options available: become a vendor or become a marketer. Some affiliate platforms are free for both parties, some are free only for the marketer and not the vendor, while some may require you to pay a one-time fee or an annual fee to become their partner.
I recommend that you review the platform thoroughly before signing up as a partner. This will help lower the risk of losing your time, product, funds, audience, or effort. You also need to check their payment methods and whether your country is supported.

All four of these parties play a very important role in affiliate marketing. I will say that there would not be a successful affiliate marketing operation without any one of them. It is highly recommended that you always use a platform as an affiliate marketer.

Types of Affiliate Marketing

Affiliate marketing can be a little tricky because most marketers only care about the money and not the well-being of the buyer. You can see many people promoting products they don't know or have never used - their only interest is the money. Thanks to Pat Flynn, who in the year 2009 broke down the different types of affiliate marketers and grouped them into three categories:

  1. Related Affiliate Marketing
  2. Unattached Affiliate Marketing
  3. Involved Affiliate Marketing

Let's explain these three types of affiliate marketing to help you identify the category each falls into and know the best one to choose if you want to venture into the business.

Related Affiliate Marketing

Related affiliate marketing is the affiliate model of promoting products you don't use or know how to use, but that are related to your niche. An affiliate marketer in this case has an audience, whether it's through blogging, YouTube, an email list, or another channel. A related affiliate marketer also has influence, which makes them a trusted source for recommending products, even if they've never used them before.
Although related affiliate marketing can generate more affiliate income, it also comes with certain risks. Since you are promoting something you've never tried before, it could be a bad product or service, which may compromise the trust your audience has in you.
It only takes one bad recommendation to lose the trust of your audience. Without trust and transparency, it will be hard to build a long-term affiliate marketing business.

Unattached Affiliate Marketing

This type of affiliate marketing, as the name implies, is "unattached"; it is when the promoter has no authority in the niche of a product, plus there is no connection between the promoter and the customer.
Often, the promoter may be running pay-per-click advertising campaigns with their affiliate link, hoping customers will click it, buy the product, and earn them a commission.

Involved Affiliate Marketing

Involved affiliate marketing refers to the model in which the promoter only recommends products and services they have used, know how they work, and truly believe in.
In this type of marketing, an affiliate marketer uses their influence to promote products and services that followers may actually need. Instead of paying for promotion through any random person, they take more time to build an audience with a specific interest. This type of audience is more likely to respond to or purchase the recommended products.

What Types of Products Do Affiliate Marketers Sell?

You may be wondering what products are sold or promoted in affiliate marketing. Your answer is here. In affiliate marketing, there are two types of products to promote or earn money with:

  1. Physical Products
  2. Digital Products

Physical products are items you can touch or feel. These include mobile phones, TV sets, books, shoes, vehicles, working tools, and more.

Digital products: are items you cannot touch, which include services, online courses, pre-recorded tutorial videos, and the like. Some affiliate platforms offer only digital products on their platform. This type of product is always easier for vendors to profit from because most of them can be created once and generate income for a lifetime.

Examples of Affiliate Marketing Platforms

There are thousands of affiliate marketing websites, each with its own requirements and modes of operation. Some operate in specific countries, while some have fewer regional restrictions. Below are a few of the most popular affiliate marketing platforms.

  • Amazon Associates: is one of the biggest affiliate marketing platforms and deals mostly with physical products. This network is owned by Amazon and is best for marketers who are interested in promoting physical products.

  • ShareASale: is one of the most popular affiliate networks because it houses many large and small merchants, unlike Amazon Associates, which only focuses on its own goods.

  • Awin (formerly Affiliate Window): is another popular affiliate network that gives you access to thousands of different merchants and products.

  • Avangate Affiliate Network: is an affiliate network focused on digital products rather than physical products.

  • CJ Affiliate (formerly Commission Junction): is another large affiliate network that brings together buyers and sellers across different categories.

  • ClickBank: is another affiliate network that has a large number of digital products and also offers physical products.

  • Walmart Affiliates: is another affiliate platform similar to Amazon Associates, dealing in physical products.

  • eBay Partner Network: is another physical product affiliate network, owned by eBay. You can earn a commission for promoting eBay-listed products.

  • FlexOffers: is another popular affiliate platform that gives you access to thousands of different advertisers/merchants and has been in business for many years.

  • As mentioned, there are thousands of affiliate marketing platforms - far too many to list on this page. The above are just a few examples. We will cover them in more detail in another chapter.

Pros and Cons of Affiliate Marketing

Affiliate marketing is worth exploring because of its continued growth and the opportunities it has created for millions of people worldwide. According to recent industry reports, the global affiliate marketing industry is estimated to be worth over $17 billion in 2025, with projections showing even stronger growth in the coming years.
Affiliate marketing also remains a low-cost business model, making it possible to start with little or no capital. However, before getting started, it’s important to understand both the advantages and challenges of building a successful affiliate marketing business.

Advantages of Affiliate Marketing

Easy to participate: Affiliate marketing is one of the easiest businesses to partake in.
As a marketer or a vendor, your role simply involves picking, creating, and marketing a product. You don't have to worry about the harder tasks, like developing, supporting, or fulfilling the offer. And once a sale is made, you receive your payment.

Low-risk business: Since there's no cost to join many affiliate programs, you can start making money with an established affiliate product or service without any upfront investment or commitment.
Affiliate marketing can generate relatively passive income through commission - the ideal money-making scenario. Though initially you'll have to invest time in creating traffic sources, your affiliate link can continue to deliver a steady and long-lasting paycheck.

Easy to scale: When you are already successful in the business, it is very easy to scale your income. Most of the time, you may double your earnings simply by trying other affiliate platforms or by adding more traffic sources.
You can also introduce new products to your current audience and build campaigns for additional products without any extra charges, while your existing work continues to generate affiliate revenue in the background.
While there are always countless products to promote as an affiliate marketer, you must understand that great affiliate marketing is built on trust from your audience.
It is always advisable to promote products you use or understand, and to know that it takes time and significant effort to become a great affiliate marketer.

Disadvantages of Affiliate Marketing

It requires patience: As I have always mentioned, affiliate marketing is not a get-rich-quick scheme. It requires time, effort, and patience to grow an audience, gain influence, and start earning income.
You may spend months or more than a year as an affiliate marketer without making any income. Many people have given up because of this. You may need to test different channels and methods to see which one resonates best with your audience.

Research the most relevant and credible products to promote. Spend time blogging, publishing free content on social media, hosting virtual events, and doing other lead-generating activities on your marketing channels. Sometimes, after months of doing affiliate marketing, you may not have made any sales.
But if you have chosen affiliate marketing, don't give up. Sometimes you need a better product; sometimes you need a larger audience. You will always need more effort and dedication.

It is commission-based: No one is handing you a daily, weekly, or monthly paycheck as an affiliate marketer.
Affiliate marketing programs work on a commission basis, whether you're paid by lead, click, or sale. Without fulfilling any of these, you may never receive a payout. Companies use temporary browser cookies to track people's actions on their content. When the specified action is taken by someone, you receive the payout, and without that action, no payout will be received.

No guarantee and no control over the program: Affiliate marketing comes with absolutely no guarantee that you will make money from it. You may try the same platform, the same product, and the same strategies as others who have succeeded, and still end up with no sales. In this case, consistency and dedication matter, and you sometimes have to go off the beaten path and develop your own strategies.
Who knows — you may later find yourself mentoring other people with the same challenges.
Now that you have seen some of the pros and cons of affiliate marketing, we hope it will help you make the right decision about how to get started. Let's now walk you through how to become an affiliate marketer.

How to Become an Affiliate Marketer

You may be wondering how you can become an affiliate marketer — or thinking something like, "I need to start making money," "there is no time to waste," or "I need to dive in right now." I will walk you through how to become a good affiliate marketer, or even a vendor. I will write another article on this topic later to provide a complete guide on best practices and how to become a successful marketer.

Before you go about becoming an affiliate marketer, you need to understand that this business is not a get-rich-quick scheme.

If you haven't made any sales as an affiliate marketer, you will never make any money, and it doesn't matter how long you have known about or been involved in the business. And if you happen to choose the vendor side of it, without a trusted and good product, you will not get far either. Here are a few steps to follow:

  1. Have a product idea: This may be based on what you already know, such as your occupation or area of expertise.
  2. Pick your platform and method: This is probably one of the most important parts of your marketing. Before choosing any platform, be sure you understand how it works so you will not lose your money. Check the available payment methods, supported countries, and types of products typically listed on the platform.
  3. Start your journey: Once you have made up your mind about affiliate marketing, never believe in failure. Always put in more and more effort.

Note: Becoming a successful affiliate marketer takes dedication, commitment, effort, and discipline. Use the following step-by-step guide to start your affiliate marketing business.

Tips for Success in Affiliate Marketing

Make a product tutorial: While your success with affiliate marketing largely depends on the overall size of your audience, another way to drive traffic is by providing a tutorial on the affiliate offer. With this strategy, users come in as students learning from you.
Afterward, many of those who are interested in the product will end up purchasing it through your link.

Talk to a product expert: This approach involves interviewing others who have used the product or service you are marketing, or even interviewing the person who creates or sells it.
This can give your review a more detailed and compelling explanation for your readers. With this step, you can more easily convert them into buyers.

Keep things legal: Don't forget to let your followers know that your post contains affiliate links. For one thing, it is required by the FTC (Federal Trade Commission). But explaining the reason for your affiliation can also help you connect with your audience on a deeper level.

Offer bonuses to users: Sometimes marketers promote their affiliate programs by offering bonuses to any buyer who purchases through their link. For example, you could give an extra product you own, a free eBook, or something similar to any follower who purchases through you.

Build an email list: It is very important to build an email list, as it is one of the best ways to connect with people outside of social media or blog posts. When it comes to purchases made as a result of receiving a marketing message, email has the highest conversion rate — approximately 66% — compared to social media and other marketing channels.

Set a distribution strategy: Share your promotional content on your blog, website, or social media platforms. If you have an email subscribers list, you can create an email marketing campaign. Be sure to have an affiliate marketing hub on your website with a resources page where you share a quick list of all the tools you use and love.
You can also run a pay-per-click advertising campaign to attract more sales, though this may only be advisable once you are already generating income.

Find relevant search terms: This step is particularly relevant for people promoting an offer through a blog post. Research the keywords people might use in a search engine to find an answer to a related problem. Google Ads Keyword Planner is a great tool that can help with this.

Consider the price: Sometimes, if not most of the time, you need to consider the price of the product you are marketing. We all know that high-priced products always come with higher commissions, but never be carried away by this alone.
You may be sitting on one high-ticket product when you could be selling multiple products at lower prices. Always check the competitors of the product so you know the price range people expect it to fall within. This can help you choose and even change products when needed.

Note: To write a good review, share your experience on your blog, social media post, Instagram Story, or YouTube video. If you're writing a personal review, give an honest opinion based on your experience and knowledge of the product. The more open you are, the more authentic you will be. People will be more comfortable following your advice if they have a feeling that they can trust you.
Trust is a key factor in your affiliate marketing efforts because people need to trust you enough to act on your recommendations. The level of trust you'll need to make affiliate sales depends on your industry and the products you're recommending. Also, know that you don't need to market every single product you come across, pick a few products that are most relevant to you and your audience.

Conclusion Earning money with affiliate marketing programs can be a rewarding way to add a new revenue stream with little or no money. Affiliate marketing takes time, but by putting in the hours to find the right affiliate network and dial in your strategy, you can build an affiliate system that generates passive income for the long term.
