What is the difference between tracking links and coupon codes?

Tracking links attribute a sale by a URL parameter stored in the visitor's browser. Coupon codes attribute a sale by the discount code used at checkout. LinkJolt supports both at the same time so no sale slips through.

Tracking links and coupon codes are two ways to connect a sale back to the affiliate who drove it. LinkJolt runs both at once, which is what we call dual tracking.

A tracking link carries a parameter that identifies the affiliate. When someone clicks it, LinkJolt stores that reference in cookies and local storage for a 30 day window. If they buy within that window, the sale is attributed.

Coupon codes

A coupon code is attributed at checkout instead of in the browser. The affiliate shares a code, the customer enters it, and LinkJolt matches that code to the affiliate when the sale reaches us. Codes credit affiliates on Stripe, Paddle, Polar, Creem and Lemon Squeezy, and Apple offer codes do the same for iOS subscriptions.

There are two ways to get the code itself. Once Stripe, Polar or Creem is connected, a code you add on the Coupons tab of the Campaigns page is created in your own account for you, with the discount you chose. Stripe and Polar take one approval on their own site, and Creem takes an API key on the Creem tab under Integrations. Otherwise the code is reference only: you create it in your payment processor first, then register the same code in LinkJolt so it knows who to credit. Paddle discounts, Lemon Squeezy discounts and Apple offer codes are always reference only, and a Lemon Squeezy code credits its affiliate only once you save a Lemon Squeezy API key under Integrations, on the Payment Links tab.

Once codes can be created in your Stripe, Polar or Creem account, a campaign can also switch on Automatic coupon codes, which gives every affiliate you approve on that campaign their own code without you adding it.

Coupon attribution is the easiest way to track sales on platforms where you cannot store browser cookies, such as some app or marketplace checkouts.

Why use both

Links catch the visitors who click through and buy directly. Coupons catch the buyers who hear about you from a creator and check out later with a code. Running both means you attribute far more sales than either method alone.
