What Is an Affiliate Link?

An affiliate link is a unique URL provided by a company or affiliate program that contains a special tracking ID assigned to an affiliate marketer.

When someone clicks that link and completes a desired action—such as making a purchase or signing up for a service—the affiliate earns a commission.

Example

A standard website URL might look like:

www.example.com

An affiliate version could look like:
www.example.com/?ref=12345

The tracking code identifies which affiliate referred the visitor.

Why Affiliate Links Exist
Companies use affiliate links to track:

Clicks
Leads
Sales
Sign-ups
Conversions

Without affiliate links, businesses would have no reliable way to determine which affiliates generated customers.
Affiliate links create a transparent system that benefits both companies and marketers.

How Affiliate Tracking Works
The affiliate marketing process is surprisingly simple.
Step 1: Join an Affiliate Program
You apply to an affiliate program and receive access to your affiliate dashboard.
Examples include:

Hosting companies
Software providers
Online course platforms
Affiliate networks


Step 2: Receive Your Unique Affiliate Link
After approval, you'll receive a custom tracking link.
Every affiliate receives a unique identifier.
This ensures commissions are attributed correctly.

Step 3: Share the Link
Affiliate marketers place links in:

Blog posts
Product reviews
Resource pages
Email newsletters
Social media content
YouTube descriptions


Step 4: Visitor Clicks the Link
When a user clicks your affiliate link, they're directed to the merchant's website.
At the same time, tracking data is recorded.

Step 5: Cookie Is Stored
Most affiliate programs use cookies.
A cookie is a small file stored in the visitor's browser.
The cookie tells the merchant:

Which affiliate referred the visitor
When the click occurred
Whether a purchase was made later


Step 6: Customer Makes a Purchase
If the visitor buys a product within the cookie duration, the affiliate receives credit for the sale.
This is how commissions are generated.

What Is an Affiliate Cookie?
Affiliate cookies play a major role in tracking referrals.
A cookie duration refers to how long the referral remains active.
Examples:

24 hours
30 days
60 days
90 days

Longer cookie durations generally provide more earning opportunities.

Types of Affiliate Commissions
Different programs pay affiliates in different ways.

Pay Per Sale (PPS)
The most common model.
You earn a commission when a purchase occurs.
Example
You recommend website hosting.
A visitor buys a hosting plan.
You earn a commission.

Pay Per Lead (PPL)
You earn money when someone completes an action.
Examples:

Free trial signups
Email subscriptions
Form submissions


Recurring Commissions
Some affiliate programs pay monthly recurring commissions.
These are particularly popular among software companies.
Example
A customer subscribes to a software platform.
You earn commissions each month they remain a paying customer.

Affiliate links can be used in various types of content.

Blog Articles
One of the most effective affiliate marketing methods.

Product reviews
Tutorials
