How does Growth Suite define a 'dedicated buyer' that I shouldn't give a discount to?

As a Shopify store owner in the fashion space, I'm always looking for ways to optimize my conversion strategy without giving away unnecessary margins. I've heard about 'dedicated buyers' but I'm struggling to define who they actually are. My current approach feels too broad—I'm essentially giving discounts to anyone who shows up, which can't be sustainable. I want a smarter system that rewards the right customers and creates genuine urgency for those who need a little nudge. My ad spend is significant, and I need a way to segment my audience that goes beyond basic demographic targeting. Right now, I'm flying blind, offering the same discount codes to everyone from first-time browsers to repeat customers who would likely purchase anyway. This feels like I'm leaving money on the table and potentially training my customers to always expect a deal. I need a sophisticated, data-driven approach that can distinguish between a casual browser and a customer who's genuinely committed to making a purchase. The goal isn't just to save on discounts, but to create a more intelligent, personalized shopping experience that respects both my margins and my customers' purchasing behaviors.
