Website redesign achieving a 5.1% conversion rate
Complete brochure site redesign with UX research, design system, mobile-first optimisation and a custom property search engine.
The challenge
Immobilier Premium, an upscale network of 12 estate agencies, suffered from an outdated website with a 72% bounce rate and sub-1% conversion rate. The goal: a full performance-driven redesign to generate qualified contacts.
UX research and information architecture
User interviews, heatmap analysis and journey audits. Rebuilt the site architecture around 3 primary paths (buy, sell, valuation), simplified navigation and created a dynamic property search engine with live filters.
Design system and development
Created a full design system (components, tokens, responsive grid) deployed on a Next.js front-end. Systematic mobile-first optimisation—68% of traffic was mobile but the old site was barely responsive.
- Lighthouse Performance score > 90 on mobile
- LCP < 1.8s
- Valuation and contact forms in 2 steps max
Conversion optimisation
Integrated social proof (synced Google reviews), contextual CTAs on every listing, and a qualification chatbot. Continuous A/B testing on valuation landing pages.
Results
Conversion rate jumped from 0.9% to 5.1%. Bounce rate fell to 35% (−50%). Qualified contact requests rose 90%, delivering an 8x+ ROI on the redesign investment within 6 months.
