Performance-Focused Frontend & UX

Get Started

Design and build frontend experiences optimised for conversion, load speed and continuous testing, with UX principles grounded in performance data.

Strategic overview

What this service actually does

Most UX design is driven by aesthetic preference and convention. We design from conversion data first, understanding where users drop off, what friction costs you conversions, and what layout and copy changes will move the metric that matters.

Performance UX is a discipline that combines design skill with analytical rigour. Every design decision is evaluated against its expected impact on conversion rate, load time and user experience quality, not just how it looks in Figma.

Areas of focus

What we actually work on

We design page layouts, component libraries and interaction patterns with conversion as the primary constraint. Designs are built as modular systems enabling rapid A/B variant creation, so testing velocity is built into the design system from day one.

All frontend work is delivered with performance budgets: maximum LCP, CLS and FID targets that are validated before and after every deploy. We monitor performance continuously and flag regressions before they impact conversion.

How we work

Our process, step by step

01

Analytics & Behaviour Audit

We analyse GA4 funnel data, heatmaps, scroll maps and session recordings to build a quantitative picture of where users are dropping off and why.

02

Conversion Audit

Heuristic review of each key page against conversion principles: hierarchy, friction, trust signals, offer clarity, and mobile layout quality.

03

Design & Prototype

Conversion-focused page designs in Figma, built as component systems with A/B variant frameworks. Every design decision documented against the conversion rationale.

04

Test & Iterate

Designs are launched as A/B tests with defined success metrics. Winners are implemented permanently; learnings feed the next design cycle.

"We'd run CRO for two years and hit a ceiling. scealy's UX audit found three structural issues in our page hierarchy that no amount of copy testing would have uncovered. Fixing those three issues added 1.4 percentage points to our conversion rate, worth more than all our previous tests combined."
