Affiliate marketing is one of the simplest ways to make money online.
You don’t need to create your own product.
You don’t need customer support.
And you don’t need to manage inventory.
Instead, you promote someone else’s product. When someone buys through your special link, you earn a commission.
According to Statista, global affiliate marketing spending continues to grow each year. That’s why many bloggers, content creators, and website owners are building affiliate sites today.
In this guide, you’ll learn exactly how affiliate marketing works — step by step.
The Basic Idea Behind Affiliate Marketing

Affiliate Marketing is SIMPLE. It’s How You Approach It.
Affiliate Marketing 101—simple yet often overlooked basics that are essential whether you’re just starting or have been in the game for a while.
Affiliate marketing works through a simple partnership between three parties:
- The company selling the product
- The affiliate promoting the product
- The customer who buys the product
Here’s how the process works in practice.
Step 1: A Company Creates an Affiliate Program
First, a company decides to promote its products through affiliates.
This means the company allows people to promote its products in exchange for a commission.
Many well-known companies run affiliate programs, including:
- Shopify
- Hostinger
- Amazon
These companies provide special tracking links that affiliates can use.
Each affiliate receives a unique link so the company can track who referred the sale.
Step 2: Join the Affiliate Program
Next, you sign up as an affiliate.
This usually involves:
- Creating an account
- Getting approved
- Accessing your affiliate dashboard
Inside the dashboard, you’ll find your affiliate links.
These links are what track your referrals.
Step 3: You Promote the Product
Once you have your affiliate link, you can start promoting the product.
Most affiliates promote products through:
- Blogs
- YouTube videos
- Social media
- Email newsletters
For example, if you write a blog post reviewing a web hosting service like SiteGround, you can include your affiliate link in the article.
When readers click the link and buy the product, the sale is tracked.
Step 4: A Visitor Clicks Your Affiliate Link
When someone clicks your affiliate link, a small tracking file called a cookie is stored in the user’s browser.
This cookie records that you referred the visitor.
The cookie usually lasts for a certain period, such as:
- 24 hours
- 30 days
- 60 days
Different companies offer different cookie durations.
Some companies offer 30–60 day tracking windows. For example, NordVPN’s affiliate program offers a 30-day cookie and recurring commissions.
Step 5: The Customer Makes a Purchase
If the visitor decides to buy the product during the cookie period, the system records the sale.
The company then knows:
who referred the customer
That means you receive the commission.
Step 6: Earn a Commission
After the sale is confirmed, the company pays you a commission.
Commissions vary depending on the product.
Typical affiliate commissions include:
- 5–10% for physical products
- 20–50% for digital products
- $50–$200 for software tools
For example:
- Hosting programs often pay $50–$100 per sale
- Software tools may pay recurring commissions
This is why many affiliate marketers prefer promoting software or online services.
Where Do Affiliate Links Appear?
Affiliate links can appear in many places.
But the most common place is inside helpful content.
Examples include:
- product reviews
- comparison articles
- tutorials
- best tools lists
For example:
- Best Hosting for Affiliate Marketing
- Hostinger Review
- SiteGround vs Hostinger
