Website UX Audit Guide: How to Find and Fix the Issues Costing You Users

A UX audit is the fastest way to figure out why visitors aren't doing the thing you want them to do. Not in a vague "our funnel could be better" way, but in a specific "this button does nothing on mobile and it's been like that for a month" way.

This guide is how to run one. What to look at, how to decide what's worth fixing, and how to turn a messy list of findings into an actual plan. It's written to be the kind of thing you come back to before every launch, not read once and forget.

What a UX audit actually is (and isn't)

A website UX audit is a systematic review of your site's user experience to find the usability problems, broken flows, accessibility barriers, and conversion blockers that get between visitors and what they came to do.

The word "systematic" is doing real work there. An audit is not a design opinion. "I don't love the hero" is a taste; "the signup button is below the fold on mobile and most people never see it" is a finding. The first one starts an argument. The second one you can fix and measure.

It's also not a redesign. A redesign rebuilds; an audit diagnoses. Most sites don't need to be rebuilt. They need the specific broken, confusing, and friction-filled moments cleaned up. Knowing the difference saves you months.

A good audit really only answers three questions: where do people get stuck, how much is each problem costing you, and what do you fix first.

When it's worth doing

Run an audit before a launch or relaunch, when real users (and the internet) are about to see the thing for the first time. Run one after any major release, because new features and refactors quietly break journeys that used to work. Run one when the numbers move the wrong way. A sagging conversion rate or a bump in support tickets almost always traces back to a UX problem somewhere. And run one on a schedule regardless, because UX decays on its own as content, links, and code drift.

How to actually run it

You can get through a useful audit in an afternoon. Do these in order; each step sets up the next.

Step 1: Pick the journeys that matter

Don't audit "the website." Audit the three to five paths that pay the bills. Something like homepage → pricing → signup, or homepage → product → cart → checkout, or search → article → email capture.

Everything else is secondary. If a path doesn't end in a conversion or a reason to come back, it can wait.

Step 2: Walk each one as a stranger

Open each journey in a fresh, logged-out browser and do it as if you've never seen the site. The trick is to actually notice the moment you hesitate; that flicker of "wait, where do I click?" is a finding. You'll push through it because you built the thing. Your users won't.

At every step, ask whether it's obvious what to do next, whether every button and link actually works and goes where it claims, and whether anything loads slowly or shifts under your cursor.

Step 3: Go break things on purpose

This is where most audits quit too early. Stop testing the happy path and start poking at the places things fall apart.

Submit forms empty, then with junk (a bad email, mismatched passwords), and see whether you get a clear error or just silence. Click around the navigation and watch for links that 404, which happens more than you'd guess after any rename. (There's a whole post on why broken links quietly kill conversions if you want to go deeper.) Trigger the empty states: an empty search, an empty cart, a fresh account with no data. And watch for pages that hang on a spinner, crash, or render blank.

Step 4: Do it again on a real phone

Most of your traffic is mobile, and mobile is where the bugs hide. Chrome's responsive mode is not the same as a real device; touch, true viewport sizes, and font rendering all behave differently.

On an actual phone, watch for horizontal scrolling (a dead giveaway that something's overflowing), tap targets that are too small or sit on top of each other, primary CTAs that got shoved below the fold, and text you have to pinch to read.

Step 5: Check the accessibility basics

Accessibility and usability overlap so much that fixing one tends to fix the other. At minimum: enough color contrast to read the text, keyboard navigation that actually reaches and operates every control, alt text on meaningful images, and labels on form fields. The WCAG guidelines are the reference if you want to go further.

Step 6: Rank by impact, not by what's easy

Now turn the pile into a plan. Score each finding on two things: how badly it hurts (does it block a journey, frustrate people, or just annoy?) and how many people hit it (a broken footer link reaches everyone; a glitch on some buried page reaches almost nobody).

Fix the things that are both severe and widespread first. A dead signup button on the homepage beats a hundred cosmetic tweaks, every time. The temptation is always to knock out the easy stuff to feel productive. Resist it.

The checklist

Use this as the repeatable pass:

• Every internal link resolves; no 404s; menus work on desktop and mobile
• Forms reject invalid input with clear, immediate errors and confirm success
• Each critical journey completes end to end without a dead end
• No crashes, infinite spinners, or blank screens
• No horizontal scroll on mobile; CTAs visible; tap targets usable
• Empty and error states guide the user forward instead of stranding them
• Contrast, keyboard access, alt text, and labels in place
• Pages load fast enough that people don't bail mid-load
• No broken images, placeholder text, or "coming soon" pages in production

It's the same backbone as a full pre-launch testing checklist, just aimed at an existing site rather than a first launch.

Manual or automated?

Both, honestly, and for different reasons.

A human catches the things no tool can: confusing copy, an awkward flow, the vague sense that a page is working against you. That judgment is the part worth your attention. What humans are bad at is doing the same exhaustive mechanical pass across hundreds of pages without getting bored and skipping steps, and then repeating it after every release.

That mechanical half is what automation is good at: crawling every page, following every link, testing every form, checking mobile and stability the same way every single time. It won't tell you whether your value prop lands, but it will reliably surface the broken links, dead buttons, failing forms, and crashes that make up most of the actual damage. HowsMyApp handles that part. It scans your site like a real user and reports the breakage with screenshots, so your human time goes to the calls that actually need a human.

The mistakes everyone makes

The same ones, over and over. Auditing the homepage and stopping, when the homepage is the most polished page you have. Collecting opinions instead of findings, so you end up with a list nobody can act on. Skipping mobile, which is most of your traffic and most of your problems. Prioritizing by what's quick to fix instead of what matters. And treating the audit as a one-time event, when UX quietly degrades with every deploy.

Frequently asked questions

How long does a UX audit take? A focused pass over your main journeys is a few hours by hand, or a few minutes if you let a scanner do the mechanical part. A full every-page audit of a big site takes longer manually but stays fast when automated.

How is this different from usability testing? An audit is an expert or automated review against known failure patterns. Usability testing watches real people attempt real tasks. They complement each other: audits are faster and catch the mechanical stuff; usability testing reveals the deeper confusion you can't see from the inside.

Do I need design skills? No. The highest-value findings (broken links, failing forms, dead buttons, crashes, mobile breakage) are objective. Anyone can spot a button that does nothing and understand why it matters when it's on your signup page.

How often should I do it? Before every launch, after every major release, and on a recurring schedule otherwise. The problems get introduced continuously, so the audit has to be a habit, not an event.

Where to start

An audit is only worth anything if it ends in fixes. So pick your single most important journey, walk it as a stranger today, write down every place you hesitate or hit a wall, and rank what you find by how badly it hurts and how many people it hits. Then make the whole thing repeatable, so UX stops quietly rotting between releases.
