Ecommerce UX guide

Mobile checkout UX audit checklist

A short checklist for finding friction in ecommerce cart and checkout journeys on mobile devices.

Why this matters

Mobile checkout problems are often small but cumulative: an unsuitable keyboard, hidden error, unclear delivery choice or form field that loses its value. Test the journey on a real phone rather than only resizing a browser window.

What to test

  • Customers can edit quantities and remove items without losing context.
  • Costs, discounts and delivery expectations are explained before payment.
  • Fields use correct labels, input types, autocomplete values and helpful errors.
  • The layout works with zoom, large text and the on-screen keyboard open.

How to review it

Test the journey with realistic products and tasks rather than reviewing an ideal screen in isolation. Include mobile and desktop, unavailable options, validation errors and the less common cases that often reveal where a template breaks down.

Use analytics to identify where behaviour changes, then review the interface to understand what may be creating uncertainty or unnecessary effort.

A practical next step

Keep the review grounded in your store

Complete several realistic scenarios, including a failed validation attempt and returning to an earlier checkout step.

Use this guide as a starting point, then test the recommendations with real products, customers and analytics data. Platform defaults and general benchmarks cannot replace evidence from your own buying journey.
