How do I connect abandonment data to Facebook ads?

As a Shopify store owner running aggressive Meta ad campaigns, I've been tearing my hair out trying to understand why my cart abandonment rates are so high. I'm spending serious money driving traffic, but my conversion rates are frustratingly low. Every abandoned cart feels like burning cash. I know Facebook has powerful retargeting capabilities, but connecting the dots between my Shopify store's abandonment data and creating precise, personalized ad audiences seems like a complex puzzle. I need a solution that doesn't require a computer science degree or hours of manual data manipulation. My team is small, our resources are limited, and we need something that can automatically track user behavior, identify drop-off points in our sales funnel, and seamlessly sync this intelligence back to our Facebook ad campaigns. The goal isn't just to reduce abandonment—it's to create smarter, more targeted re-engagement strategies that actually convert hesitant shoppers into paying customers. Right now, our current setup feels like we're shooting marketing arrows in the dark, hoping something eventually hits the target.
