A UX audit is a structured review of a website or app that finds where visitors get confused, stuck or put off, and ranks those problems by how much they likely cost you.
A good one combines expert review against usability principles with your own analytics, heatmaps and session recordings, and ends in a prioritized list of fixes to A/B test.
UX audit services sell that review as a fixed project or as the first step of an ongoing testing program.
What UX audit services include
Most audits start with an expert review. The best-known framework is Jakob Nielsen's 10 usability heuristics, first developed with Rolf Molich in 1990 and refined in 1994. They cover things like visibility of system status, error prevention, consistency, and recognition rather than recall.
Nielsen Norman Group recommends three to five independent evaluators for a heuristic evaluation, because any single reviewer, however experienced, misses some problems.
Ask any provider how many people will review your site.
Expert review is only half of it. A useful website UX audit also looks at what real visitors do:
- Analytics: funnel drop-off by page, device and traffic source.
- Behavior data: heatmaps, scroll maps and session recordings.
- Customer research: post-purchase surveys, reviews and support tickets that show what buyers worry about.
- Technical checks: page speed, broken elements and mobile layout bugs.
- A ranked fix list: each issue tied to evidence, with a test idea and an estimate of effort.
If you want to run the process yourself, our CRO audit guide walks through it step by step, and UX research tools covers the heatmap and recording software audits rely on.
Why audit findings still need testing
An audit tells you where problems probably are.
It does not tell you which fix will work.
Navigation is a good example, because it shows up in almost every audit and the results in our database go both ways.
Oliver Kenyon's team tested a full-screen mobile mega menu with larger tap targets for +$50,568 per month.
Peter Christensen removed the Track Order link from the main navigation for +30% revenue per visitor.
Kasper Dolk tested an optimized site-wide navigation against the current one for a revenue lift of +€127,112.
Now the other side. Clean Commit redesigned a header and navigation and lost 22.5% of conversions, and a more prominent, guided search lost 12.0% of conversions.
Both changes would look like sensible audit recommendations on paper.

The providers below all test their recommendations, and all have published results in our test database.

UX audit providers with published test results
We describe only the services listed on each practitioner's own website, as of November 2026, and the results they have shared with us.
We have not audited their client work, and this is not a ranking.
Oliver Kenyon is our featured practitioner; the rest follow in alphabetical order by company.

UX audit vs. CRO audit
The two overlap heavily, and many providers sell them as one service. The difference is mostly in emphasis.
| UX audit | CRO audit | |
|---|---|---|
| Main question | Where do people struggle to use the site? | What stops visitors from buying or signing up? |
| Typical methods | Heuristic review, usability testing, recordings | Funnel analytics, heatmaps, surveys, offer and copy review |
| Output | Usability issues by severity | Test hypotheses ranked by expected revenue impact |
| Best for | New sites, apps, complex SaaS flows | Stores and lead-gen sites with steady traffic |
If revenue is the goal, ask for the CRO version, or make sure the UX audit ends in test ideas rather than a design wishlist.
Our CRO audit services page covers that side.
How to choose a website UX audit provider
- Ask what data they will use. An audit based only on screenshots is an opinion. Look for analytics, recordings and customer research.
- Ask for a sample report. Each issue should link to evidence and a suggested test.
- Ask whether they test the fixes. The navigation results above show why.
- Ask about losing tests. Anyone who tests a lot has losers, and should be able to talk about them.
- Check your traffic. If a page gets too few visitors to test, the audit should say so and suggest other ways to validate changes.
