The UX audit checklist: find what is costing you users before you redesign
A UX audit reviews a live product against usability heuristics, analytics, accessibility standards and real task flows to find where users struggle. Done before a redesign, it tells you which screens to fix first — and often shows that a targeted fix beats starting again.
Key takeaways
- Audit before you redesign; most products need surgery, not a rebuild.
- Combine heuristics with analytics — one says what is wrong, the other says how much it costs.
- Score every issue by severity and frequency so the fix list ranks itself.
- Record real sessions; a two-minute recording settles arguments a report cannot.
Redesigns are usually commissioned because something feels wrong. A UX audit replaces that feeling with a ranked list: the five places users get stuck, how many people hit each one, and what fixing it is worth.
The four lenses of a useful audit
- Heuristics
- An expert review against established usability principles — visibility of status, error prevention, consistency, recognition over recall.
- Analytics
- Funnels, drop-off points, rage clicks and search terms with no results. This is what puts a cost on each problem.
- Accessibility
- Contrast, keyboard access, focus order, labels and target sizes against WCAG 2.2 AA.
- Task flows
- Walking the three tasks that matter most — sign up, buy, get help — exactly as a new user would, and timing them.
Run these on your top three tasks
- Can a first-time user say what this product does within five seconds of landing?
- Is the primary action obvious on every screen, and is there only one?
- Do forms validate inline, before submit, in plain language?
- Are empty, loading and error states designed, or left to defaults?
- Does every screen work at 320px wide and with 200% text size?
- Can the whole flow be completed by keyboard alone?
- Do analytics show where people leave, and does that match the expert review?
Turning findings into a fix list
| Severity | Meaning | Fix when |
|---|---|---|
| Critical | Blocks the task for many users | This sprint |
| Major | Slows or confuses most users | Next sprint |
| Minor | Cosmetic or rare | With the next redesign |
