Understanding exactly how affiliate marketing works β from click to commission β demystifies the whole industry and helps you make better decisions about which programs to join, which content to create, and why your earnings look the way they do. Here's the complete step-by-step breakdown.
Step 1: You Join an Affiliate Program
Every affiliate journey starts with joining a program. You can join directly through a merchant's website (like Amazon Associates at affiliate-program.amazon.com) or through an affiliate network that manages programs for multiple merchants (ShareASale, CJ Affiliate, Impact, Rakuten, ClickBank).
After approval β which may be instant or take a few days β you get access to your unique affiliate links. These links contain your affiliate ID, which is how the system knows you sent the traffic.
Step 2: You Create Content with Affiliate Links
You write a blog post, shoot a YouTube video, create a Pinterest pin, or send an email newsletter that includes your affiliate links. The content should genuinely help your audience β the more useful your content, the more people click, and the more you earn.
Example: You write "Best Standing Desks for Home Offices" and include affiliate links to Amazon, Wayfair, or direct merchant programs for each desk you recommend.
Step 3: A Visitor Clicks Your Link
When someone clicks your affiliate link, two things happen almost simultaneously:
- They're redirected to the merchant's website (your reader doesn't see any of this β it's seamless)
- A cookie is stored in their browser with your affiliate ID and a timestamp
This cookie is how the merchant's system remembers that you sent this visitor, even if they don't buy immediately.
Step 4: The Cookie Duration Window
Cookie duration is one of the most important numbers in affiliate marketing. It determines how long after the click you get credit for a purchase.
- Amazon Associates: 24 hours β If someone clicks your link and buys within 24 hours, you earn commission. After that, nothing.
- HubSpot: 90 days β If someone clicks your link today and subscribes in three months, you still earn.
- SEMrush: 120 days β Four months of attribution window.
Longer cookie duration = more opportunities to earn from a single click. When choosing programs, always check cookie duration alongside commission rate.
π‘ Pro tip: If a merchant uses "last click attribution," the most recent affiliate link clicked before purchase gets the commission. This matters if your reader clicks multiple affiliate links in a session.
Step 5: The Purchase Happens
When the visitor completes a purchase (or a qualifying action β depending on whether it's a CPS, CPA, or CPL program), the merchant's system checks the browser cookie, identifies your affiliate ID, and records the commission.
Step 6: Commission Is Recorded and Held
Most programs hold commissions for 30β90 days before paying out. This waiting period accounts for returns and refunds. If the customer returns the product, the commission is reversed. Once the hold period passes, the commission becomes "available" for payment.
Step 7: You Get Paid
Payment typically happens once you hit a minimum threshold (usually $10β$100, depending on the program) via bank transfer, PayPal, or check. Most programs pay monthly, some bi-weekly.
A Complete Example with Real Numbers
Say you run a home office blog. You publish "10 Best Standing Desks" and include an affiliate link to a $499 desk with an 8% commission.
- Your article gets 5,000 monthly visitors
- 12% click the affiliate link = 600 clicks
- 2% of those buy = 12 purchases per month
- 12 Γ $499 Γ 8% = $479/month from one article

How Affiliate Networks Fit In
Networks like ShareASale, Impact, and CJ Affiliate act as intermediaries. They provide standardized tracking, payment infrastructure, and a marketplace where you can discover and apply to thousands of programs. Many merchants prefer networks because they handle the operational complexity of affiliate management. As an affiliate, networks make it easier to manage multiple programs from one dashboard.
