UX/UI Audit & Conversion Optimization

Most websites lose 70–90% of their visitors before a single conversion. A UX/UI audit reveals exactly why. At Kosmoweb, we analyze every step of your user journey - from landing page to checkout or contact form - using heatmaps, session recordings, and conversion data to find the friction points that silently kill your revenue. Then we give you a clear, prioritized plan to fix them.

Our audit methodology goes beyond surface-level observations. We evaluate your information architecture, navigation patterns, form design, call-to-action placement, trust signals, page load performance, and mobile experience against both industry best practices and your specific competitors. Every recommendation comes with expected impact, implementation difficulty, and clear before/after specifications your development team can execute immediately.

UX optimization and SEO are deeply connected. Google measures user engagement signals like bounce rate, time on page, and interaction depth. A site that frustrates users does not just lose conversions - it loses rankings too. Our audit addresses both dimensions, ensuring your website design delights visitors and satisfies search engine algorithms simultaneously.

Whether you run an e-commerce store, a corporate website, or a web application, better UX means better business results. Our clients typically see 15–40% conversion rate improvements after implementing audit recommendations. We also offer website redesign services for sites that need more than incremental fixes - sometimes the most cost-effective path forward is a fresh start built on solid UX foundations.

Heuristic evaluation applies Nielsen's 10 usability heuristics as a structured walkthrough of your site, scored severity 0-4. The ones most commonly violated on CZ business sites: visibility of system status (forms that submit silently with no confirmation), match between system and real world (technical jargon where plain language would do), user control and freedom (no clear way to undo or escape modal states), consistency and standards (the contact button styled differently across pages), error prevention (forms accepting invalid input then rejecting on submit), and recognition rather than recall (navigation that requires memorizing where things live). Each violation gets a concrete fix and a severity score that drives the prioritization.

We map the three to five critical paths through your site — homepage to contact, category to product to checkout, blog to lead capture — then walk each one as a fresh user, recording every friction point. Heatmaps from Hotjar or Microsoft Clarity (free, surprisingly good) show where users click, hover, and rage-click. Session recordings reveal the real moments of confusion. Funnel analysis in GA4 quantifies drop-off rates between steps. A typical mid-funnel drop above 40% indicates either confusion or a missing trust signal at that step. The output is a path-by-path improvement plan, not a generic list of UX 'best practices'.

Information architecture is the unsexy part of UX that determines whether anyone can find anything. We card-sort the existing content with at least 5-8 representative users to test whether your taxonomy matches their mental model — most CZ business sites organize content by internal department logic, not by user task. We measure findability with first-click testing (does the user click the right nav item on first try?), check for orphan pages with no nav path, and verify search functionality where catalog size justifies it. Menu depth should stay at two levels for most marketing sites; e-commerce can go three. Anything deeper requires search to be excellent.

WCAG 2.2 AA compliance is increasingly a legal requirement in the EU (the European Accessibility Act enters force June 2025 for many B2C digital products). Our audit covers: color contrast (4.5:1 for normal text, 3:1 for large text, verified with axe DevTools), keyboard navigation (every interactive element reachable and operable without a mouse, visible focus indicators), screen reader compatibility (semantic HTML, ARIA where needed, alt text on informative images), form labels properly associated, error messages programmatically linked, and respect for prefers-reduced-motion. We run automated checks with axe and Lighthouse plus manual screen-reader testing with NVDA or VoiceOver, because automated tools catch only 30-40% of real accessibility issues.

Conversion audit segments your funnel into landing, consideration, and action stages, with micro-conversions tracked at each. Landing: bounce rate by source, scroll depth, time-to-first-interaction. Consideration: pages per session, return visit rate, content engagement depth. Action: form starts vs completions, cart adds vs purchases, signup starts vs completions. Each micro-conversion drop-off becomes a hypothesis to test. We have seen contact form completion go from 18% to 41% by removing two non-essential fields and adding a single-line response-time SLA. SEO and conversion compound: better engagement signals also improve rankings, which delivers more qualified traffic to optimize on.

Forms are where UX dies most often. Audit checklist: field count (the absolute minimum to qualify the lead), input types correctly set for mobile keyboards (type='email' surfaces the symbol keyboard on iOS, type='tel' triggers numeric), inline validation that runs on blur not on every keystroke, error messages next to the field with specific guidance ('Email format invalid' is worse than 'Please include the at-sign'), progressive disclosure for long forms (multi-step beats one long form for completion rate), and autosave for forms longer than three fields. Disable autocomplete only where genuinely necessary — fighting browser autofill is hostile to users and a common source of accessibility complaints.

Mobile UX is its own discipline, not desktop minified. Thumb-zone analysis: primary actions belong in the bottom-third of the screen because that's where thumbs naturally rest one-handed; top-bar actions require thumb gymnastics. Gesture support where it improves over taps (swipe to dismiss modals, pull to refresh on listings). Viewport handling that respects safe-area insets on iPhones with notches and dynamic islands. Touch target spacing of 8-12px between adjacent interactive elements to prevent fat-finger errors. Modal handling that doesn't trap focus or break the back button. Test on actual mid-range Android devices (most CZ users) at least as often as on iPhones — the performance and ergonomics differ significantly.

Audit output is a deliverables package, not a PDF that ends up in a drawer. We deliver: heatmap and session recording exports for every key path, an annotated screenshot library marking every issue with severity and fix complexity, a prioritized recommendations spreadsheet with effort-vs-impact matrix (the 4-quadrant prioritization is unfashionable but it works), specific copy and design changes ready for the development team to implement, and a 60-90 day implementation roadmap with monthly review cadence. Audits without implementation plans are intellectual exercise. The point is changes shipped to production, measured against a baseline, with verifiable improvement.
