Introduction
Many people understand the basic idea of affiliate marketing:

Someone buys it.
You earn a commission.
However, very few people understand what actually happens between the click and the commission.

What happens when someone clicks your affiliate link?
How are commissions tracked?
And why do some affiliates get paid while others lose commissions?
In this guide, you’ll learn exactly how affiliate marketing works behind the scenes, from the moment a visitor clicks an affiliate link until the affiliate receives payment.

The Affiliate Marketing Workflow
Affiliate marketing follows a structured process that involves multiple participants and technologies.

↓
Sale Is Attributed

Commission Is Approved

Affiliate Gets Paid
Every commission earned follows this journey.
Understanding each step helps you become a more effective affiliate marketer.
The Four Key Participants
The Merchant
The merchant is the company selling the product or service.
Examples include:
- Web hosting companies
- SaaS providers
- Online course creators
- E-commerce brands
The merchant pays commissions to affiliates.
The Affiliate
The affiliate promotes products and sends potential customers to the merchant.
Examples include:
- Bloggers
- Website owners
- YouTubers
- Influencers
- Email marketers
The Customer
The customer is the person purchasing the product or service.
Without customers, no commissions exist.
The Affiliate Network
Some companies use affiliate networks to manage tracking and payments.
Popular examples include:
- Impact
- CJ Affiliate
- ShareASale
- Awin
These platforms simplify affiliate management.
What Happens When Someone Clicks an Affiliate Link?
Let’s say you publish a hosting review article.
A visitor clicks your affiliate link.
Example:
https://merchant.com/?ref=sitelaunchlab
The visitor is redirected to the merchant’s website.
Behind the scenes, the tracking system records information such as:
- Affiliate ID
- Click timestamp
- Landing page
- Device information
- Referral source
This information helps identify who should receive credit for future purchases.
How Affiliate Tracking Works
Tracking is the foundation of affiliate marketing.
Without tracking, merchants would have no way of knowing who referred customers.
When a click occurs, the system records:
- Affiliate identifier
- Session data
- Referral source
- Tracking parameters
Modern tracking platforms process millions of clicks every day.
Their purpose is simple:
Determine which affiliate deserves credit for the sale.
What Are Affiliate Cookies?
Cookies are small files stored in a visitor’s browser.
Their purpose is to remember who referred the visitor.
For example:
Day 1:
A visitor clicks your affiliate link.
Day 15:
The visitor returns directly to the merchant’s website.
Day 20:
The visitor purchases.
Because the cookie is still active, you receive the commission.
Without cookies, affiliate marketing would be much less effective.
Understanding Cookie Duration
Every affiliate program defines how long a cookie remains valid.
Common cookie durations include:
- 24 Hours
- 30 Days
- 60 Days
- 90 Days
Some SaaS programs even offer longer attribution windows.
Generally speaking:
Longer cookie durations are more favorable for affiliates.
Attribution Models Explained
Attribution determines which affiliate receives credit.
Last Click Attribution
This is the most common model.
Example:
Affiliate A refers a visitor.
Later, Affiliate B refers the same visitor.
Affiliate B gets the commission because they generated the last click.
First Click Attribution
Less common.
The first affiliate receives credit regardless of later referrals.
Multi-Touch Attribution
Some advanced programs distribute credit across multiple touchpoints.
This model is becoming more common in enterprise marketing environments.
How Affiliate Networks Track Sales
Affiliate networks act as intermediaries.
Their responsibilities include:
- Tracking clicks
- Recording sales
- Validating commissions
- Processing payments
Because networks manage thousands of affiliate programs, they provide centralized reporting for affiliates.
Instead of managing multiple systems, affiliates can monitor performance from one dashboard.
How Commissions Are Calculated
Not all affiliate programs pay the same way.
Fixed Commission
Example:
Every Sale = $100
Percentage-Based Commission
Example:
Product Price = $200
Commission Rate = 20%
Commission Earned = $40
Recurring Commission
Popular among SaaS companies.
Example:
Customer Pays $50 Monthly
Commission Rate = 30%
Affiliate Earns $15 Every Month
As long as the customer remains subscribed.
Commission Approval Process
Not every sale is approved immediately.
Most programs use a review period.
Common reasons include:
- Refund requests
- Fraud checks
- Chargebacks
- Policy violations
Typical statuses:
Pending
Sale recorded but not yet approved.
Approved
Commission validated and payable.
Rejected
Commission disqualified.
How Affiliate Payments Work
After approval, affiliates receive payments according to program terms.
Common payment methods:
- PayPal
- Bank Transfer
- Payoneer
- Wise
Most programs require a minimum balance before payment is issued.
Examples:
- $50
- $100
- $200
Payment schedules are usually:
- Monthly
- Biweekly
- Net-30
- Net-60
Common Tracking Problems
Sometimes commissions are lost.
Common causes include:
Expired Cookies
The customer purchased after the attribution window ended.
Ad Blockers
Some tracking scripts may be blocked.
Multiple Devices
A customer clicks on one device but purchases from another.
Tracking may not always transfer.
Invalid Orders
Refunded or canceled purchases usually remove commissions.
A Real-World Affiliate Marketing Example
Imagine you’re promoting a web hosting company.
Step 1:
A visitor searches Google for:
“Best web hosting for beginners”
Step 2:
They discover your review article.
Step 3:
They click your affiliate link.
Step 4:
A 30-day cookie is stored.
Step 5:
They spend several days researching.
Step 6:
They return and purchase a hosting plan.
Step 7:
The merchant records the sale.
Step 8:
Your affiliate dashboard shows a new commission.
Step 9:
After validation, you receive payment.
This simple process powers billions of dollars in affiliate revenue every year.
