How to Run a UX Design Audit That Spots and Solves Design Issues

A UX design audit is a structured review of a website or app that finds the design issues making it harder to use, then turns them into a ranked list of fixes. Done well, it tells you exactly what’s costing you signups or sales, and what to change first.

Here’s the kind of thing it catches. A meal-kit company in Austin couldn’t work out why so many subscribers canceled instead of pausing. The “Skip this week” option existed. It was just a pale gray text link sitting under a big orange “Cancel plan” button. Customers who only wanted a week off saw one clear choice and took it.

No one on the team had noticed, because they all knew where the skip link was. That’s the problem an audit solves. If you’d like a quick read on your own site before going further, UX Audit Tool is free to use.

What a UX Design Audit Covers (and What It Doesn’t)

An audit looks at how design choices affect what people can do. Layout, labels, buttons, forms, feedback messages, and accessibility all fall inside it. Brand strategy and back-end performance mostly sit outside, though an audit will flag them when they get in the way.

You’ll hear two related terms a lot. A website UX audit follows real user journeys on a marketing site, like finding pricing or booking a call. A website design audit is narrower and focuses on visual hierarchy, consistency, and trust signals.

The method below works for both, and for logged-in apps and dashboards too. Only the journeys change.

How to Run a UX Design Audit in 6 Steps

Step 1: Pick the Journeys That Matter

Don’t audit “the whole site.” Pick two or three tasks that tie directly to revenue or support costs. Good examples include buying a product, requesting a quote, booking a demo, or changing a subscription.

Write each one as a sentence: “A first-time visitor on a phone finds a plan and starts a free trial.” That sentence becomes your test.

Step 2: Gather Evidence Before You Judge Anything

Opinions start arguments. Evidence ends them. Before anyone critiques a single screen, collect what you already have:

• Analytics: where people drop out of each journey
• Support tickets and chat logs: questions that come up every week
• Session recordings: rage clicks and dead ends, from tools like Hotjar or Microsoft Clarity
• Reviews: words like “confusing” or “couldn’t find”

Patterns across two or more sources are where you’ll find the biggest problems.

Step 3: Walk Each Journey Against Proven Heuristics

Now go through each task yourself, on desktop and on a phone. Check every screen against Nielsen Norman Group’s 10 usability heuristics, a set of principles UX teams have used for decades.

A few questions catch a lot:

• Does the page show what happens after each click?
• Are labels written in the customer’s words or the company’s?
• Can people undo a mistake easily?
• Is the most important action also the most visible one?

Screenshot every issue as you go. You’ll need them later.

Step 4: Check Accessibility

About 1 in 4 US adults has some type of disability, according to the CDC. If your design shuts them out, you’re losing a large share of potential customers.

Test against WCAG Level AA, the level the Department of Justice adopted in its 2024 ADA rule for state and local government websites. Start with contrast, keyboard navigation, form labels, and error messages. Private businesses can face ADA claims too, and the DOJ’s web accessibility guidance is a good place to understand the basics.

Step 5: Watch Real People Try It

Your team knows the site too well to see it fresh. Recruit a handful of people who match your customers and ask each to complete one journey while thinking out loud.

You don’t need a big study. Nielsen Norman Group’s research shows that testing with five users uncovers most usability problems in a single round.

Step 6: Write Findings Your Team Can Act On

One quick way to sink an audit is a 60-page report nobody reads. Keep each finding short:

Field	Example
Issue	“Skip this week” link is hard to see next to “Cancel plan”
Evidence	Cancellation survey answers keep saying “just wanted a break”
Why it matters	Customers who’d pause are canceling instead
Fix	Make “Skip a week” a full button, placed above “Cancel plan”
Severity	High

Rank everything by severity and effort, then ship the high-severity, low-effort fixes first. Re-test each one after it goes live so you know it worked.

Common Design Issues and How to Solve Them

You’ll see these in audits across very different industries.

Design issue	What users experience	How to solve it
Competing buttons	Not sure which action to take	One primary button per screen, with secondary actions styled quieter
Vague labels	Can’t find a feature	Use the words customers use in support tickets
Silent errors	Form fails with no explanation	Explain what went wrong next to the field
Low-contrast text	Hard to read on a phone outdoors	Meet the WCAG contrast ratio of 4.5:1 for normal text
Long forms	Give up halfway through	Ask only for what you need now and collect the rest later
Hidden contact details	Can’t reach a person when stuck	Put a phone number or chat link in the header

What to Choose: Free Tools or Paid Specialists?

Both have a place. The right choice depends on how complex your site is and how much UX experience your team has.

Free UX audit tools are a sensible first pass for small and mid-sized sites. UX Audit Tool, for example, checks every page of your site at no cost. You enter your name and email and verify a one-time code to see the full report. Run a free audit to see what it flags on your pages.

If you search for a free AI UX audit, you’ll find several options. They’re quick at spotting surface problems like low contrast or cluttered layouts across many pages. What they can’t do is understand your business or why a page exists.

That’s where UX audit services come in. A specialist adds user research and a roadmap tied to your goals. They make the most sense for complex products and regulated industries.

A practical middle path: start with a free UX audit, fix the obvious issues yourself, then bring in specialists for anything that needs research or a bigger rethink.

Start With One Journey This Week

Pick the task that matters most to your revenue. Walk through it on your phone and note every moment you hesitate. Then fix the worst one before Friday. That single loop teaches you more than any report.
