Cart Abandonment Rate measures how often buyers add items but leave without paying, a direct signal of checkout friction. Surprise fees, limited payment options, and slow flows all push it up. Each recovered cart is revenue you already earned the buyer's intent for, so reducing abandonment is usually cheaper than acquiring fresh demand to replace it.
