Most businesses assume checkout is a solved problem. It processes orders, nobody has complained loudly enough to justify a rebuild, so it stays untouched while every other page gets redesigned around it. Baymard Institute's ongoing audit of the checkout experience across more than 180 leading US and EU ecommerce sites says otherwise. The majority still get it wrong, and the gap between a mediocre checkout and a good one is worth more revenue than almost any other single fix on the site.
Baymard's audit of 180-plus leading ecommerce sites found 64 percent rate mediocre or worse on checkout usability, with only 2 percent rated good and none rated perfect. Baymard estimates fixing checkout UX alone can lift conversion rate by up to 35 percent on a large ecommerce site, more than most landing page or product page work delivers on its own.
What Baymard actually found
Baymard Institute's current-state research, published on its ongoing checkout usability benchmark, grades the top US and EU ecommerce sites by name against a detailed checkout usability rubric. The headline number: 64 percent of sites rate as mediocre or worse, only 2 percent rate as good, and not a single site in the study rated as perfect. These are large, well-funded retailers with dedicated UX teams, not small businesses running an out-of-the-box theme. If checkout is this hard to get right at that scale, a small or mid-size store's checkout is unlikely to be an exception by accident.

| Perfect | 0% |
Why checkout stays broken while everything else gets redesigned
Checkout is the most expensive part of a site to touch and the least visible part to leave alone. It touches payment gateways, tax logic, shipping rules and often a legacy form built years ago by whoever was on the team at the time. A homepage redesign is a project marketing wants. A checkout redesign is a project engineering has to own, with real risk if something breaks during a sale. That asymmetry is why checkout usability debt accumulates for years while the rest of a site gets refreshed on a normal cadence.
The 35 percent conversion opportunity hiding in your checkout
Baymard's research puts the potential conversion rate gain from checkout usability improvements at up to 35 percent for a large ecommerce site. That figure is larger than what most teams expect from a landing page redesign or a product page overhaul, and it makes intuitive sense once you consider where checkout sits in the funnel. A shopper who reaches checkout has already decided to buy. Every point of friction from there on is pure loss, not a persuasion problem but an execution one, which is usually cheaper to fix than a persuasion problem once you know where to look.
Do not start a checkout audit by guessing where the friction is. Watch five to ten real sessions through your own checkout on mobile, note every point someone pauses, backs up or abandons, and fix those specific points before touching anything cosmetic. Baymard's own multi-year tracking shows usability regresses as fast as it improves without this kind of ongoing review.
A practical checkout UX audit checklist
- Confirm guest checkout is offered and is the visually dominant option, not buried below a forced account creation step.
- Count the required form fields. Every field beyond name, address, payment and contact detail needs a specific justification.
- Check that error messages are specific, appear inline next to the field, and explain exactly what to fix rather than a generic "invalid input."
- Confirm total cost, including shipping and tax, is visible before the final payment step, not revealed for the first time on the last screen.
- Test the entire flow on a real mobile device without zooming or horizontal scrolling at any step.
- Check that trust signals (security badges, return policy, customer support contact) are visible near the payment fields, where hesitation is highest.
The first visible section of each checkout step carries more weight than it looks like it should. Nielsen Norman Group's research on scrolling behavior found users spend roughly 57 percent of their page-viewing time above the fold, so whatever is visible before a shopper scrolls, whether that is the order summary or the first form field, deserves the most scrutiny in an audit, not the least.
Where the checklist connects to specific fixes
A general audit tells you where to look, not always how to fix what you find. If form field count is the problem, our guide on which checkout form fields are actually killing conversion has the 2026 cut list. If the friction is at payment method rather than form design, our coverage of digital wallet checkout and passkey login at checkout covers the two fastest wins we have seen this year. Either way, treat the audit as the diagnosis and these as the specific prescriptions, not the other way around.
If you want a second set of eyes on your own checkout, our conversion optimization team runs exactly this kind of audit before recommending a single change, and if the underlying build itself is the constraint, our website design and development team can scope what a rebuild would actually take.
Frequently asked questions
What did Baymard's 2026 checkout audit find?
Baymard Institute's ongoing audit of over 180 leading US and EU ecommerce sites found 64 percent rate as mediocre or worse on checkout usability, with only 2 percent rated good and none rated perfect. Baymard also estimates the average large ecommerce site could gain up to a 35 percent conversion rate increase from checkout UX improvements alone.
Why do so many established ecommerce sites still get checkout wrong?
Checkout is rarely rebuilt once it works well enough to process orders, so usability debt accumulates for years while the rest of the site gets redesigned around it. Payment gateways, tax logic and legacy form fields make checkout the most expensive part of a site to touch, so most teams optimize everywhere except there.
What is the conversion opportunity in fixing checkout UX?
Baymard's research puts the potential conversion rate gain from checkout usability improvements at up to 35 percent for a large ecommerce site, which is larger than the gain typically available from landing page or product page optimization alone, because checkout is the step closest to a completed sale.
What should a checkout UX audit actually check?
At minimum: whether guest checkout is offered and easy to find, how many form fields are required versus optional, whether error messages are specific and appear inline, whether trust signals and total cost are visible before the final step, and whether the mobile checkout flow works without zooming or horizontal scrolling.
How often should checkout UX be reviewed?
At least once a year, and immediately after any change to payment providers, tax rules or shipping options, since those changes are the most common source of new friction. Treat checkout review as a standing item, not a one-time project, because Baymard's own multi-year data shows usability regresses as fast as it improves without ongoing attention.
Does above-the-fold attention matter for checkout pages too?
Yes. Nielsen Norman Group's research on scrolling behavior found users spend roughly 57 percent of their page-viewing time above the fold, which means the first visible section of a checkout step, whether that is the cart summary or the first form field, carries a disproportionate share of the attention a shopper gives that page.
The takeaway
A 64 percent failure rate among the biggest ecommerce sites in the world is not a reason to feel better about your own checkout, it is a reason to actually look at it. Run the audit, watch real sessions, and fix the specific friction points you find rather than doing a cosmetic refresh. The revenue sitting in that gap is larger than most other single optimization on the site.
