Users abandon their cart, don't finish signing up, leave negative reviews or simply don't come back. The causes are often invisible to those who work on the product every day. That's exactly what a UX audit is for: looking at a website, app or software product with expert eyes and structured methods to find the user experience issues holding back business results.
What is a UX audit?
A UX audit is a systematic analysis of a digital product that assesses usability, accessibility, interface consistency and how well its flows lead users to their goals. The outcome isn't a list of opinions but a report with documented issues, severity levels and recommendations ranked by impact and effort.

When do you need a UX audit?
- Key metrics (conversion, retention, activation) are falling or below expectations.
- You're planning a redesign and need to know what to keep and what to change.
- The product has grown in layers and the interface has lost consistency.
- You want to benchmark your product against its main competitors.
- You need to check compliance with accessibility requirements.
How a UX audit is done: the phases
1. Goals and context
It starts with business goals and target users. An effective audit doesn't weigh everything equally: it focuses on the flows that matter most, such as onboarding, search, checkout or contact requests.
2. Heuristic evaluation
UX experts assess the interface against established principles such as Nielsen's 10 heuristics: visibility of system status, consistency, error prevention, recognition rather than recall and so on. Each issue is documented with screenshots and rated by severity.
3. Data analysis
Analytics, conversion funnels, heatmaps and session recordings show where users really get stuck. Combining quantitative data with expert review separates real problems from theoretical ones.

4. Accessibility and benchmarking
Contrast, text size, keyboard navigation and screen reader compatibility are checked against the WCAG guidelines. A competitor benchmark shows which patterns users already expect.
5. Report and roadmap
The final deliverable is a document with issues, evidence and recommendations, organised in an impact/effort matrix. The team immediately knows which quick wins to tackle and what to plan for the medium term.

UX audit vs usability testing: what's the difference?
An audit relies on expert analysis and existing data and is quick and cost-effective; usability testing observes real users using the product and reveals issues no expert could predict. The two methods complement each other: the audit often identifies critical areas and testing explores them in depth.

UX audit: frequently asked questions
How long does a UX audit take?
From 2 to 6 weeks, depending on the size of the product, the number of flows analysed and whether benchmarks and user tests are included.
What do you need to get started?
Access to the product and analytics tools, plus an initial session with the team to share goals, metrics and known issues.
How often should it be repeated?
For products that evolve continuously, once a year or before any major change is a good rule of thumb.
Conclusion
A UX audit turns vague feelings ("the app isn't working as it should") into concrete issues and clear priorities. It's often the investment with the fastest return for a digital product that's already on the market. GlueGlue's UX team carries out audits and benchmarks for apps, platforms and digital services for companies of every size.
