    UX & Design Case Studies, Measured in Conversion

    Design work judged by what it moved, not how it looked. A redesign worth a 28% conversion lift, microcopy worth 35% more clicks, trust patterns for fintech interfaces, and reducing cognitive load in flows where users were dropping out.

    Each study shows the before state, the specific change, and the measured result — including where a visually better design performed worse.

    What these studies have in common

    Measure the change, not the mockup
    Every study here has a before and after number: 28% more conversions, 35% more clicks, higher funnel completion. Design decisions were kept or reverted on that basis.
    Words are interface
    The microcopy study moved click-through 35% without changing a single layout. Button labels, headlines and nudges are usually the cheapest available conversion lever.
    Trust is a design output in fintech
    Visual hierarchy, social proof and consistent design systems changed whether users believed a financial product enough to continue. That is measurable, not decorative.
    Less to process, more completed
    Reducing cognitive load in complex flows improved task completion more than any single visual improvement — the recurring finding being that users abandon effort, not ugliness.
