What Is Affiliate Marketing? A Complete Guide for Beginners

Are you looking for a way to earn extra money online? If you're anything like me, you've probably heard about affiliate marketing but weren't sure what it actually involves or whether it's worth your time.
After diving deep into this topic, I wanted to share everything you need to know about affiliate marketing – what it is, how it works, and whether it might be a good fit for you.
Quick Summary: Affiliate marketing is a revenue-sharing business model where you earn commissions by promoting other companies' products. It's been around since 1994, and while it can be profitable, success requires genuine effort and the right approach.
What Is Affiliate Marketing?
Affiliate marketing refers to programs that aim to sell more products for a company through partnerships with third party online sales people called affiliates or publishers. Unlike traditional contextual advertising, affiliate marketing programs allow content publishers to connect directly with advertisers.
Here's why this model works so well: A successful affiliate marketing campaign can lead to higher income for publishers compared to publishing contextual ads from services like Google AdSense. From an advertiser's standpoint, affiliate marketing is efficient because the reward system is based on the publisher's productivity. The advertiser only needs to pay if the publisher successfully facilitates a sale.
The History of Affiliate Marketing
The affiliate marketing business model isn't new at all. It's been around shortly after the first few businesses started offering products and services on the web. The commission system was actually inspired by offline sales people who have been paid via commission for the longest time – particularly common in cosmetic, homeware, car and pharmaceutical industries.
Here are the key milestones:
1994: The first recorded transition to online happened with PC Flowers and Gifts. Founder William J. Tobin designed and patented the use of revenue sharing and tracking of visitor activities. The first affiliate network was the Prodigy Network, an IBM-owned subscription service.
1996: Amazon launched what we now call Amazon Associates. At the time, Amazon focused on selling books. Website owners could post banner ads or links leading directly to specific book product pages, earning commission when visitors purchased through their links.
2006: Sales generated by affiliate marketing in the UK alone amounted to $2.92 billion, showing just how much this industry had grown.
2011: Google's Panda update changed everything. This algorithm update penalized websites with poor content – many of which were spam websites monetized by affiliate links. After Panda, websites with excellent, useful content rose to fill the top positions in search results.
Today: The emergence of social media and mobile devices has transformed affiliate marketing. Many successful affiliates don't even own websites anymore – they use Facebook pages, YouTube channels, and Instagram accounts to generate sales.
How the Business Model Works
There are three key players in affiliate marketing:
1. The Advertiser
This is the business that wants to promote its products or services. They set up affiliate programs or sign up with affiliate networks to manage their programs. Their goal is to sell more products and reach new markets through the internet.
Advertisers provide the tools publishers need, including:
- Marketing materials for promoting products
- Platforms to make participation easier
- Account dashboards for tracking performance
- Commission payments
2. The Consumers
These are the people who buy the products. The best consumers are both willing (interested in the product with a personal reason for wanting it) and able (have the technical knowledge and funds to complete online purchases).
3. The Publisher (That's You!)
Publishers post the marketing materials so consumers can view them. Most affiliate programs require publishers to have an online asset – usually a website – to attract consumer attention. However, depending on program guidelines, publishers can also use social media marketing and other methods.
The Reality of Making Money as a Publisher
Let me be honest about what you're up against. Though billions of people use the internet daily, you won't reach the majority of them. Here's the reality:
- A big chunk of online users don't speak English
- Among English speakers, only a small percentage is interested in your specific topics
- Even among interested people, only a small percentage actually buy online
- Many prefer brick-and-mortar stores when available
- Those who buy online often stick to popular sources like Amazon
Two Paths to Success
The most successful publishers earn consistently by establishing themselves as authorities in their chosen fields. Here are two approaches:
The Expert Approach
If you're already an expert in your field, you can create content related to your profession. For example:
- A gym trainer could create a website with workout content for people who can't attend classes, while promoting fitness-related products
- A carpenter could provide free carpentry lessons and use Amazon Associate links for tools and products used in the lessons
The Learning Journey Approach
You don't have to be an expert to start. You can document your journey learning a new skill:
- A beginner carpenter could show their learning process and share the tools they use
- Instead of giving advice from experience, you share lessons as you learn
Many people online are beginners wanting to learn something. Most educational websites are paid and expensive. You can provide free versions and earn through affiliate income instead of charging for information.
What You Need to Get Started
To establish yourself as a trusted source, you'll need:
Proof of expertise: Create an "about" page with your credentials and achievements. Include photos of yourself working to show authenticity.
Useful content: Provide valuable information that keeps visitors coming back to your website.
The right products: Promote products and services you actually use yourself, using affiliate links to direct visitors to these items.
Is Affiliate Marketing Worth It?
Affiliate marketing can work, but it's not a get-rich-quick scheme. Success requires:
- Consistent effort in creating valuable content
- Patience to build an audience over time
- Genuine expertise or willingness to learn in your chosen area
- Understanding that this works best as supplemental income
The internet has changed dramatically since affiliate marketing began. Text content no longer rules – videos and images now dominate. People spend time in apps rather than browsing websites. If you want to succeed today, you need to master social media marketing alongside traditional website content.
The Bottom Line
Affiliate marketing is a legitimate business model that's been around for decades. While it can generate income, success requires treating it like a real business – not a side hobby you do whenever you feel like it.
The old ways of succeeding still have value, but if you want your affiliate marketing to thrive in today's environment, you need to adapt to how people actually consume content now: through social media, videos, and mobile apps.
