Fix Your Broken Influencer Tracking: The Discount Code Attribution Playbook

Are you tired of investing in influencer marketing only to lose track of the results? You provide custom UTM and affiliate links, but they're constantly misused. Influencers use link shorteners that strip your parameters, miscopy URLs, or simply forget to use the link. This creates a 'dark social' black hole, making it impossible to attribute sales to the correct partner and undermining your entire campaign strategy.

Stop relying on fragile links. This playbook implements a creator-friendly, robust tracking system using unique discount codes. Instead of a complex URL, you'll give each influencer a simple, memorable code for your Gumroad store. When a customer uses that code at checkout, a direct integration automatically tags them in ConvertKit with the influencer's unique identifier. This provides perfect attribution, enabling personalized email sequences and, crucially, allowing you to track the long-term value of the customers each influencer brings in.

Expected Outcomes

  • Achieve 100% accurate sales attribution for every influencer campaign.
  • Eliminate data loss from broken UTM links and 'dark social' traffic.
  • Identify your highest-performing influencers with concrete sales data, not just vanity metrics.
  • Deliver personalized welcome emails to customers based on the influencer who referred them.
  • Calculate the true long-term value (LTV) of the audience acquired from each influencer.

Integration Logic

  • Gumroad Purchase Tagging

    When a customer successfully completes a purchase on Gumroad, a signal is sent to ConvertKit via a native API integration. This signal contains the customer's email and the specific product they purchased. ConvertKit then finds the subscriber associated with that email address (or creates a new one if they don't exist) and applies a pre-configured tag. This tag can then be used as a trigger for automated email sequences, for segmenting broadcasts, or for internal tracking.
