UX Audit Checklist: 42 Questions to Run Before You Redesign

Most redesigns start with a problem the team can feel but can’t precisely locate. Conversion is low. Users aren’t activating. The product looks dated. So a brief goes out, new layouts get sketched, and months later the team discovers the new version has different problems — because nobody diagnosed the original ones.

This checklist prevents that. It’s organized around the 6-Layer UX Audit Framework we use at Masterly — each layer surfaces a different category of failure, and each category connects to different business outcomes. Run the full checklist before a redesign, or use individual layers as targeted diagnostics when something specific isn’t working.

For each question, classify what you find using the Masterly Impact Tiers:

• Strength — working well, worth explicitly preserving
• Friction — usable but creating unnecessary drag on engagement or conversion
• Blocker — active failure costing you users, conversions, or revenue right now
• Opportunity — not broken, but a meaningful improvement is available

Layer 1: Design Review (Q1–Q8)

Design review evaluates screens against usability principles — hierarchy, clarity, consistency, feedback. Most audits start here. Most audits also stop here, which is why they miss most of what’s actually affecting business outcomes. Use it as a foundation, not a conclusion.

Real audit finding: In one product, a sponsor’s promotional block had stronger visual weight than the site’s own navigation. The first thing users saw on load was an advertisement — not the content they came for.

‍

Layer 2: Information Architecture (Q9–Q15)

IA problems are almost never visible in individual screens. They emerge when you map the full structure: every page type, every navigation path, every dead end. The tools here are crawlers and user research, not screen review.

Real audit finding: A media platform with 100,000 monthly visitors had no structured path from article completion to a related article. Users who finished reading had one designed option: close the tab. Over 17,000 pages were buried deeper than 3 clicks from the homepage.

‍

Layer 3: Monetization and Conversion (Q16–Q22)

This is the layer most design teams skip — which is precisely why it contains the highest-value findings in most audits. Every item here connects directly to revenue or activation.

Principle: Ask users to pay before they’ve experienced value and you train them to distrust the product. The sequence that converts: first action — value delivery — upgrade prompt. Products that gate core features before first use systematically lose the users most likely to pay.

‍

Layer 4: Technical Performance (Q23–Q29)

A UX audit that ignores performance is diagnosing half the patient. Slow pages create user experience failures that no design improvement can compensate for — you cannot redesign your way out of a 22-second load time.

Real audit finding: Mobile LCP of 22.2 seconds. CLS of 0.405 — elements jumping while the page loaded, causing users to tap the wrong targets. 11,831 internal pages returning 5xx errors, reachable through ordinary navigation. No design change addresses any of these.

‍

Layer 5: SEO Health (Q30–Q36)

For content and SaaS products, SEO health directly affects organic traffic volume, which affects every other metric downstream. A product with strong UX and poor SEO health is invisible to the audience it’s designed for.

Real audit finding: A Screaming Frog crawl at 52% completion had already discovered 326,000+ URLs — far above what the site’s content volume warranted. 25,008 mixed-content issues and 12,087 permanent redirects, each fragmenting link authority and consuming crawl budget.

‍

Layer 6: Analytics (Q37–Q42)

Analytics validates or challenges everything the other five layers surface. Without it, you’re working from observation and inference. With it, you’re working from evidence — and you can prioritize by actual impact, not by assumption.

Real audit finding: A media platform showed 78.3% desktop / 21% mobile — an unusual split for a content site where the industry benchmark is 60–70% mobile. Mobile users weren’t returning. The likely cause: mobile performance failures suppressing repeat visits before analytics could even record them.

How to Use Your Results

Once you’ve worked through the checklist, you have classified findings across six layers. The prioritization logic is straightforward: fix Blockers first, regardless of implementation cost. These are active failures — users are being lost, misled, or frustrated right now.

After Blockers, address high-impact Frictions starting with the ones that are cheapest to fix. Quick wins build momentum and demonstrate audit ROI before the larger structural work begins.

Structural problems — IA redesign, performance overhaul, SEO cleanup — belong in a parallel workstream, not competing with feature work. A platform with a 47/100 mobile performance score can’t absorb new features without making the underlying problem worse.

One final principle from real audit work: document your Strengths with the same rigor you apply to failures. Products that redesign without an explicit list of what’s working often accidentally remove the things quietly responsible for their best metrics. Clean reading experience, no intrusive modals, fast checkout — these are competitive advantages. Easy to miss. Easy to remove.

If you've worked through this checklist and found more Blockers and Frictions than you expected — that's the point.

A Masterly UX audit gives you a prioritized roadmap across all six layers, with findings classified by urgency and mapped to the business outcomes they affect.
