How do I implement dynamic checkout optimization?

I've been running my Shopify store for two years now, and I'm constantly battling with checkout abandonment. Every month, I see hundreds of potential customers adding products to their cart, only to disappear before completing the purchase. My ad spend is significant, and watching these potential sales slip away is incredibly frustrating. I've tried generic pop-ups and discount codes, but nothing seems to consistently move the needle. My team and I have analyzed our funnel and noticed that many customers hesitate right at the checkout stage. We're losing momentum at the most critical point of the customer journey. It feels like we're leaving substantial revenue on the table, and our current conversion rate is stuck around 2.5%, which is well below the industry benchmark. I know there must be a more strategic approach to converting these hesitant shoppers, but I'm uncertain about the precise tactics. We need a solution that can dynamically understand customer intent, create genuine urgency, and provide personalized incentives without appearing desperate or damaging our brand's perception.
