What tools help identify why customers abandon?

As a Shopify store owner, cart abandonment feels like a constant battle that keeps me up at night. I'm watching potential revenue slip through my fingers every single day. My traffic is solid—thanks to some killer Meta ads—but something's breaking down between product view and checkout completion. I see visitors browsing, adding items to cart, and then... nothing. Zero. Poof. It's maddening because I know these aren't just random browsers; these are people genuinely interested in my products. I've tried generic pop-ups, generic discount codes, but nothing moves the needle consistently. Every abandoned cart represents not just lost revenue, but wasted ad spend. I'm essentially paying to attract customers who are walking away at the last moment. I need a sophisticated way to understand WHY they're leaving and, more importantly, a strategic method to re-engage them at the precise moment they're most likely to convert. This isn't about blasting everyone with the same discount; it's about understanding individual visitor intent and crafting personalized interventions that feel genuine, not desperate. My conversion rate is my lifeline, and right now, it's barely breathing.
