Website UX Checklist: How to Find Usability Problems Before Your Users Do
A practical UX checklist to find usability problems before users do. Heuristics, patterns, and quick tests used by Designing Dots.
Contents
Introduction
Usability problems rarely announce themselves as usability problems. They show up as low demo conversion, high bounce on pricing, or sales says prospects are confused.
The team blames copy or traffic quality. Usually, it's friction hiding in plain sight: unclear hierarchy, actions that don't stand out, choices that overwhelm, feedback that never arrives.
This checklist is how we find those issues before users have to report them. It's based on heuristics, but applied to real B2B and D2C websites, not abstract lab sites.
How to use this checklist
You don't need a full usability lab. For each section, test three user types: a new visitor (no context), a motivated buyer (task to complete), and a returning visitor (finding something again). Record your screen and narrate confusion out loud.
Score each item: Pass (no friction), Partial (works but with effort), Fail (blocks task or creates error).
1. Clarity & Cognitive Load
Is it obvious what this is and what to do next?
- Above-the-fold clarity: Does the headline explain outcome + audience without support text? If you need the subhead to understand the headline, rewrite headline.
- One primary action per viewport: Does each section drive one action? Hero with 3 equally weighted buttons is a choice overload.
- Progressive disclosure: Is complex information (features, integrations, pricing tiers) layered or dumped? Good UX shows summary first, detail on demand.
- Scannability: Can you understand the page by reading only H2s and bold text? If not, restructure.
At Designing Dots, we've seen that teams optimize for completeness, not comprehension. Adding more feature blocks increases load faster than it adds clarity. Remove one block and conversion often goes up.
2. Navigation & Wayfinding
Can people go where they need without thinking?
- Label sense: Would a customer label your nav that way? Test by asking 5 users to sort your pages into your current nav labels. Mismatch equals label problem.
- Active state: Do visitors know where they are? Underline, background, or breadcrumb should persist.
- Backwards foraging: If someone lands deep via Google, can they understand what site they are on and where to go next without hitting Back?
- Search that helps: Does site search show popular queries, recent pages, and actual product docs — or 10 blog posts about the keyword?
Mobile navigation check
Open your nav on mobile. Is the primary CTA visible without scrolling in the overlay? Is it thumb-reachable? Does closing the menu require precise X tapping? These are conversion killers on mobile.
3. Forms & Conversion Points
Are you asking at the right moment with the right effort?
- Timing: Are you asking for email before delivering value? Hero email wall works only if trust is already high.
- Effort: Count fields, clicks, and context switches to complete primary conversion. Over 5 fields for a demo is friction unless you show why you need it.
- Error clarity: Trigger an error intentionally. Does it tell users where the error is, why it happened, and how to fix it inline? Invalid input is never enough.
- Feedback loop: After submit, does the user know what happens next? We review and get back in 24h beats Thank you.
- Calendar handoff: If you embed Calendly or Chili Piper, does it show timezone correctly and handle reschedule/cancel without email?
Common friction we find: Required Company size or Use case that sales doesn't actually use. We remove it and add it as optional post-booking.
4. Information Hierarchy & Visual System
Does visual weight match task importance?
- F-pattern alignment: Are headlines, key actions, and proof placed along natural scanning lines, not fighting them?
- Contrast for action: Is your primary button color distinguishable for color-blind users and does it have one style everywhere?
- Density check: On pricing pages, does spacing let users compare plans without losing row alignment?
- Content rhythm: Is every section same height and structure? Uniformity looks clean in Figma but creates banner blindness in real browsing.
5. Trust & Credibility in Flow
Does trust build as friction grows?
- Proof timing: Do you show specific proof right before high-friction asks? Logo wall alone before demo is weak. Logo + outcome metric + peer testimonial is strong.
- Security and social reassurance: Near forms, do you show privacy note, social proof, or expected outcome instead of marketing copy?
- External validation: Are third-party badges (SOC 2, G2, reviews) linked and recent? A 2021 badge without year feels stale.
6. Responsiveness & Edge Cases
Test the unhappy paths.
- Slow connection: Throttle to Fast 3G. Does content still render meaningfully before JS loads? Does LCP element appear first?
- Empty states: No search results, filtered list empty, feature not available on plan — do these explain what to do next?
- Long content: Does your page handle long customer names, long integration lists, or translated text without breaking layout?
- Keyboard and screen reader: Can you tab through primary flow, see focus styles, and operate menus without a mouse?
7. Content That Creates Usability Problems
Usability isn't just UI. Copy is UX.
- Vague CTA labels: Get Started vs. Start 14-day trial — specific labels outperform generic by reducing uncertainty.
- System status: If product requires setup, does marketing site set expectations about time-to-value?
- Comparison honesty: Does your comparison page compare fairly or cherry-pick? Users notice and it erodes trust for the rest of the journey.
Why this matters for product-led companies
For PLG and sales-assisted PLG, website UX directly dictates activation. The gap between website promise and product onboarding is where churn starts.
If sign-up takes 10 seconds but pricing page was confusing, users arrive with wrong expectations and churn after first session. Fixing UX upstream reduces support tickets downstream more effectively than adding help articles.
Common mistakes
- Testing only with internal team. They know too much. You need 5 outsiders who match ICP.
- Fixing symptoms with color. Making button bigger when problem is value prop clarity wastes time.
- Only testing happy path on Chrome desktop. Your users are on Safari mobile, Outlook email client, and spotty wifi.
- Treating UX audit as one-time. The best teams run this checklist every quarter before sprint planning.
Designing Dots Approach / Framework: Friction Audit Matrix
We score usability problems on two axes: User Impact (blocks vs. annoys) and Fix Cost (copy/template change vs. system rebuild).
- High Impact / Low Cost: Re-label nav, rewrite hero H1, fix form error messages, move proof above fold. Ship this week.
- High Impact / High Cost: Restructure IA, rebuild pricing logic, redesign onboarding hand-off. Requires sprint.
- Low Impact / Low Cost: Polish microcopy, adjust spacing, add breadcrumbs. Backlog for design system cycle.
- Low Impact / High Cost: Leave until data says otherwise.
This stops teams from debating personal preferences and starts prioritizing by evidence. We pair it with session replays for each high-impact item so stakeholders feel the friction, not just read about it.
Key Takeaways
- Most usability problems feel like conversion or content problems — map them to friction points.
- Test with three personas: new, motivated buyer, and returning visitor across desktop and mobile.
- Forms, navigation, and proof timing cause more drop-off than aesthetics.
- Edge cases (slow network, errors, empty states) define brand quality more than hero animation.
- Use Impact vs. Cost matrix to ship fixes quickly without redesign paralysis.
Next Steps / Internal Ecosystem
Use this UX checklist alongside the Website Audit Checklist. Audit first explains what's not working; UX checklist explains why it's not working for humans.
If your audit shows content confusion, pair with brand messaging frameworks. If it shows system inconsistency, it's time for a design system sprint.
