If you choose to track affiliate sales with either Both Links & Codes, UTM Links, or Safelinks, you have the ability to customize the landing page of the tracking links generated.
To set this up, go to the Programs tab on your dashboard and click on the program whose tracking links you'd like to customize.
From within the program builder page, head to the Attribution & Discounts tab.
Scroll down to the Landing Page card and expand the dropdown.
You can customize landing pages of tracking links to be:
Your store's homepage
Any product page
Any collection page
Any custom page on your store
Click Save & Exit once you've chosen your preferred landing page.
