If you choose to track affiliate sales using Links & Codes, UTM Links, or Safelinks, you can see from where any particular affiliate is driving traffic and how many link clicks are coming from each traffic source. The 'Referral URL' data for each affiliate can help you track their traffic sources, whether through different social media channels, their blog, etc.
To check this, navigate to the Affiliates tab on your Social Snowball dashboard. Then, choose the specific affiliate for whom you wish to review the referral URLs on their affiliate link. You can locate the affiliate by searching for their name, email address, or discount code/link.
This will bring you to the affiliate's profile page. Scroll down to the Top Referral URLs section.
