E-Commerce UX Audit: 40 Checkpoints That Lift Revenue

By the UXreviewer.io team4 min read

An e-commerce UX audit checks every stage of the shopping journey, from landing and search to product page, cart, checkout and post-purchase, for friction that costs sales. The 40 checkpoints below give you a structured way to find those revenue leaks, whether you run the audit yourself or brief an external team.

Use the checklist stage by stage, on both desktop and mobile, with a real product and a real payment method where possible. Mark each checkpoint as pass, partial or fail, add a screenshot for every fail, then prioritize the fails on your highest-traffic pages first.

Homepage, navigation and search (checkpoints 1-8)

Shoppers arrive with different levels of intent. Some know exactly what they want and go straight to search; others browse categories. Both paths need to work.

1. The homepage makes the shop's range and key benefit clear within seconds.
2. Category names use customer language, not internal product codes.
3. The search field is visible on every page, including on mobile.
4. Search tolerates typos, synonyms and plural forms.
5. Zero-result searches suggest alternatives instead of a dead end.
6. Filters match how customers choose, such as size, price, availability and use case.
7. Applied filters are visible and easy to remove one by one.
8. Sorting options include the ones shoppers expect, like price and newest.

Category and product listing pages (checkpoints 9-14)

Listing pages are where shoppers compare. Every product card should give enough information to decide whether to click.

1. Product cards show image, name, price and key differentiators consistently.
2. Stock status and delivery estimates are visible before clicking where possible.
3. Variants such as colors are indicated on the card.
4. Pagination or infinite scroll preserves position when users return from a product.
5. Sale prices and original prices are presented honestly and clearly.
6. Listing pages load quickly even with many images.

Product detail pages (checkpoints 15-23)

The product page answers the questions a shop assistant would answer in person. Missing information is one of the most common reasons shoppers leave to search elsewhere.

1. Images can be zoomed and show the product from several angles and in use.
2. The price, including any extra costs known at this point, is unambiguous.
3. Size guides, dimensions or compatibility details are easy to find.
4. Variant selection updates the image, price and availability immediately.
5. The add-to-cart button is prominent and stays reachable on mobile.
6. Delivery time and cost are shown near the add-to-cart button.
7. Return policy is summarized on the page, not only in the footer.
8. Reviews are easy to scan and can be filtered.
9. Out-of-stock products offer alternatives or a back-in-stock notification.

Cart and checkout (checkpoints 24-34)

Checkout is where small annoyances become abandoned carts. Every extra field, surprise cost or unclear error is a reason to stop.

1. Adding to cart gives clear feedback without forcing users away from shopping.
2. The cart allows editing quantity and variants without starting over.
3. Total cost, including shipping and taxes, is visible before checkout begins.
4. Guest checkout is available, with account creation offered afterward.
5. The checkout asks only for necessary information.
6. Address entry supports autocomplete and browser autofill.
7. Payment methods common in your markets are offered, including wallets where relevant.
8. Errors appear inline next to the field and explain the fix.
9. Entered data is preserved if a payment fails or the user goes back.
10. Trust signals and contact options are visible during payment.
11. Discount code fields do not distract shoppers who have no code.

Mobile, performance and accessibility (checkpoints 35-38)

Many shoppers browse on phones, and since 28 June 2025 the European Accessibility Act applies to many e-commerce services in the EU. Check scope with our European Accessibility Act guide; this is not legal advice.

1. Touch targets, forms and filters work comfortably on small screens.
2. Pages load quickly and do not shift while loading; see Core Web Vitals as a UX metric.
3. All product images and controls have text alternatives and keyboard support.
4. Color contrast is sufficient, especially on prices, buttons and errors.

Post-purchase and AI shopping features (checkpoints 39-40)

The experience does not end at the confirmation page. Clear order communication reduces support load and builds the trust that brings people back. And as AI assistants and shopping agents become more common, the way your shop presents information to them matters too, as discussed in agentic commerce checkout UX.

1. Confirmation pages and emails state what was ordered, the total, delivery estimate and how to get help.
2. Any AI shopping assistant discloses that it is an AI, gives accurate product information and hands over to a human when needed.

How do you prioritize the results?

Not every fail is equally costly. Start with checkout and product page issues on your best-selling products, because they affect the most revenue. Then fix search and filter problems, which influence how many shoppers ever reach a product page. Cosmetic issues on rarely visited pages can wait.

Record your baseline conversion, cart abandonment and average order value before shipping changes, so you can attribute improvements. If you want an outside view with commented screenshots and mockups, you can book a call for free.
