How does cart abandonment change during Black Friday?

Every Black Friday, I've watched my cart abandonment rates go absolutely crazy. Last year, we saw our typical 60-70% cart abandonment spike to nearly 85%. It's like customers become these hyper-distracted shoppers, jumping between dozens of stores, adding items to carts everywhere, but completing purchases almost randomly. The sheer volume of traffic is overwhelming—our store saw 3x the normal daily visitors, but conversions didn't scale proportionally. I'm spending more on ads, driving more traffic, but feeling like I'm losing control of the purchasing funnel. The problem isn't just about losing potential sales; it's about the wasted ad spend and the missed opportunity to convert these highly motivated seasonal shoppers. My team and I have tried generic countdown timers, blanket discounts, and even extended sale periods, but nothing seems to create that perfect balance of urgency and personalization. We need a smarter approach that understands each visitor's unique purchase intent, especially during this high-stakes shopping period where every percentage point of conversion can mean thousands in additional revenue.
