In this article, we will explore the significance of cross-domain affiliate tracking and how it can enhance your conversion attribution in affiliate marketing. We’ll discuss the benefits of implementing tracking software and strategies for optimizing your affiliate program.

So, let’s dive in!

⚙️ Step-by-Step: Setting Up Cross-Domain Affiliate Tracking in Scaleo

Now, in this article we assume that you are already using Scaleo as your affiliate marketing software and you are familiar with most of the settings and know your way around it.

1. Use Scaleo’s Click ID Parameter

Make sure your affiliate tracking links include the {click_id} macro:

https://yourdomain.com/click?offer_id=123&affiliate_id=999&click_id={click_id}

This is vital for matching the conversion later—you’ll pass this click ID across domains.

2. Enable Click ID Forwarding via URL or Cookie

On your landing page (Domain A), grab the click_id from the URL and either:

  • Append it to any outgoing links to Domain B (?click_id=12345)
  • Or store it in a 1st-party cookie (recommended for smoother UX):
// Store click_id in a cookie
const urlParams = new URLSearchParams(window.location.search);
const clickId = urlParams.get('click_id');
if (clickId) {
document.cookie = `click_id=${clickId}; path=/; domain=.yourdomain.com; max-age=3600;`;
}

If Domain A and Domain B do not share a parent domain, cookie tracking won’t work—URL forwarding is your best bet.

3. Pass Click ID to the Conversion Page (Domain B)

Ensure that by the time the user lands on the page where the conversion fires (e.g., registration or purchase confirmation), the click_id is still present—either in the URL or pulled from the cookie.

Example:

https://domain-b.com/thank-you?click_id=12345

4. Fire the Postback or Pixel with the Click ID

At the point of conversion, make sure you send the postback to Scaleo with the⁣:click_id

https://track.scaleo.io/postback?click_id=12345&goal_id=1

This ties the conversion back to the affiliate’s original click across domains.

5. (Optional) Use Custom Domains for Seamless Experience

Use Scaleo’s custom domain feature to white-label tracking links. This prevents browser issues (like redirect blocking) and improves trust:

  • Example:track.yourbrand.com instead of track.scaleo.io

Set this up via Settings > Domain Settings.

6. Test the Flow

Walk through a full journey:

  • Click affiliate link → Domain A
  • Navigate to Domain B → preserve click_id
  • Complete conversion → fire postback

Check Scaleo’s Conversion Report to see if attribution links properly.

Understanding Cross-Domain Affiliate Tracking

In the cross-device digital landscape, it’s essential for affiliate marketers to track conversions across multiple domains in order to accurately attribute performance and make data-driven decisions. This is where cross-domain affiliate tracking comes in.

Cross-domain tracking refers to the ability to track user behavior across different domains and devices, allowing you to see the entire customer journey and attribute conversions to the appropriate affiliate. This is particularly important in affiliate marketing, where many conversions may happen across multiple touchpoints.

Multi-Channel Tracking

One of the main challenges in cross-domain tracking is accurately tracking conversions that occur across multiple channels. With customers interacting with your brand through a wide range of channels—from social media to email to display ads—it’s important to have a tracking system that can accurately capture all of these touchpoints.
