The first time someone asked me for a custom affiliate link, I panicked a little.
I’d just launched my affiliate program, and someone I really wanted to partner with asked, “Hey, can I get a custom tracking link?” And there I was… Googling like a mad person, trying to act like I totally had it together.
Turns out, it’s not that complicated. But it is one of those things you want to set up right the first time. Because let me tell you, nothing’s worse than realizing a month later that none of your affiliate links were tracking correctly. (Yeah… that happened.)
So let’s break this down — plain and simple.
First Things First: What’s a Custom Affiliate Link?
Basically, it’s a unique URL that tracks which affiliate referred a sale. You can give each affiliate their own custom link, which helps you know who brought in what traffic (and who to pay!). These links usually have a special parameter at the end — like ?ref=amyblog or something similar.
And bonus: you can customize those links so they look clean, branded, and even easier to remember.
Step 1: Use an Affiliate Platform or Plugin
If you’re using Shopify, WordPress, or Gumroad — chances are, there’s already a plugin or built-in feature that makes this easy.
Here are a few I’ve tried (and liked):
-
ThirstyAffiliates (WordPress) – great for cloaking and organizing links.
-
Rewardful (for SaaS) – built specifically for recurring revenue.
-
Tapfiliate, Refersion, or PartnerStack – solid platforms for managing bigger affiliate programs.
-
Shopify Collabs – super easy if you’re on Shopify.
Once you’re signed up, most tools will let you generate a custom link in just a couple clicks.

Step 2: Customize the Link Slug
This is where the fun begins. Instead of giving someone a generic string of numbers and letters, you can make the URL look like this:
or
People love seeing their name (or brand) in the link. It makes it feel more personal — and makes it easier to promote, too. Just make sure the slug is short and clear.
Tip: If you’re using a tool like Pretty Links (on WordPress), you can cloak the ugly affiliate URL and turn it into something like:
Clean. Professional. Easy to remember.
Step 3: Test the Link Before Sending It Out
This might sound basic, but always test the custom link before sharing it. I’ve had links that 404’d, links that didn’t track properly, and even one that led to the wrong product. (Whoops.)
Just click the link yourself. Make a test purchase (or ask a friend to), and confirm it’s tracked in your dashboard.
Some platforms let you simulate clicks to make sure tracking pixels are firing correctly. Use that!
Step 4: Share It With Context
When I send an affiliate their custom link, I don’t just drop the URL and bounce. I send it with:
-
A short thank-you note
-
A reminder of the commission percentage
-
Promo materials (images, copy, testimonials)
-
A few tips for where to use the link (Instagram bio, YouTube description, blog post, etc.)
A little effort here makes the affiliate feel supported — and that usually leads to better results.

Step 5: Track Performance and Tweak as Needed
After launch, keep an eye on how the links are performing. Which affiliates are sending traffic? Who’s converting?
One of my favorite things is creating UTM parameters to get more specific with tracking in Google Analytics. It’s like putting a magnifying glass on your traffic. You can tag things like:
It sounds geeky, but once you get the hang of it, it’s gold.
And if you want to go deeper into optimization, you have to read about tracking affiliate sales and performance. It dives into what metrics actually matter.
Final Thoughts: Keep It Simple, But Do It Right
Creating custom affiliate tracking links isn’t rocket science, but it is important to get it right. A clean, personal link builds trust, looks better in promotions, and makes tracking easier for you and your affiliates.
Don’t overcomplicate it. Use the tools available, test your links, and stay organized. Honestly, once you’ve set up a few, it becomes second nature.
And hey, if you mess it up the first time (like I did)? No worries. You’ll figure it out. Just double-check before your next launch and you’ll be golden.
