What you need to know
Customers may leave when the total changes, delivery is unclear, or checkout asks for unnecessary information. Find the step where shoppers stop before choosing a fix.
How to apply it
Review analytics and support questions, show fees early, reduce form fields, offer guest checkout where suitable, display payment methods, and test on mobile.
Common mistake to avoid
A discount pop-up cannot fix a broken payment flow or surprise fees. Diagnose friction and measure one change at a time.
