Who was involved?

  • Me (Wolfgang) as UX Designer
  • Led 100+ stakeholder sessions with management and IT teams
  • Founder of the company
  • Two developers (Backend + Frontend)

Timeline

  • 2021 - Present (3+ year engagement)
  • Development is still in progress

The Problems

  • Search rankings went from top 3 to page 3 (where websites go to die)
  • Users were abandoning the site fast without converting
  • The owner started to redesign the portal by himself, without any foundation in UX or UI
  • About 70 % decrease in monthly revenue

The original design (before) was created by the founder, who had no background in UX or UI design. The goal was to improve usability and conversion rates while maintaining the existing brand identity and most of the available material design templates.

A small selection of dozens of improved UI elements

Insurance rate card

Users struggled to understand and compare insurance options due to unclear information hierarchy and poor readability, making it difficult to choose the right plan.

Mobile application interface

Filter

Users didn't really understand the implication of the percentage Numbers for the services and couldn't find important filters that where hidden behind the "enhanced filter"-Button

Mobile application interface

Insurance Plan Details

Users abandoned insurance detail pages due to poor information architecture. Critical details were hidden behind multiple layers of progressive disclosure, making it difficult for non-experts to find and compare essential coverage information.

Mobile List View

This critical comparison interface had poor mobile filter usability. Users couldn't easily apply or remove filters, hindering their ability to find relevant insurance plans.
