Should I use server-side or client-side abandonment tracking?

As a Shopify store owner, I've been wrestling with cart abandonment for months. I'm spending significant money on ads to drive traffic, but watching potential customers slip away at the checkout feels like throwing cash out the window. Every abandoned cart represents lost revenue, and I know my current tracking method isn't giving me the full picture. I've tried a few basic tracking tools, but they feel like band-aids on a deeper problem. I need a solution that not only tracks abandonment comprehensively but actually helps me convert those wavering customers. My current setup shows me basic metrics, but I want to understand WHY customers are leaving and have intelligent tools to bring them back. It's not just about tracking; it's about creating a smarter, more responsive shopping experience that turns hesitation into conversion. I'm looking for a technical solution that doesn't require me to become a coding expert, but still provides deep, actionable insights into my store's performance.
