Problem

The listings page contained valuable information, but the experience made it hard to access. It was long, illogically ordered, and difficult to scan, meaning many users weren't reaching key content before dropping off. An Omnibus survey (Sep 2020) also highlighted a broader usability perception gap, with only 4% of users rating OneRoof as “easy” to use compared to competitors. The page needed to:

  • Reduce scrolling and improve information findability
  • Prioritise what property hunters cared about most
  • Modernise visual design to align with our updated homepage and style guide

Goal

Improve the listings journey by making high-value information easier to find, faster to understand, and simpler to navigate, while retaining the depth of content users came to OneRoof for.

Impact

  • Page length reduced ~30% (desktop + mobile)
  • +46% call-agent conversion
  • Bounce rate -42.8%

The approach

Prioritising what matters to property hunters

The existing page offered a lot of detail, but users struggled to locate the information they cared about most. Omnibus survey data helped us rank what mattered most to property hunters:

  1. The latest property listings
  2. Accurate property estimates
  3. CVs and council data
  4. Recent sales information
  5. Mortgage calculator

This gave us a clear basis for restructuring the page around user value rather than internal content ordering.

Reordering the page (validated with A/B tests)

Before redesigning visuals, we tested whether reordering content alone would change behaviour. Across variants, we kept agent-supplied listing information and contact details at the top and focused tests on reordering OneRoof-supplied content beneath it.

Key shifts included:

  • Moving estimate, RV, history, and council data higher on the page
  • Pushing lower-priority content (e.g. the area map) further down

The reorder had an immediate impact on the estimates page, increasing registrations on page by 17.4%. On the listings page, the reorder had no meaningful impact on user behaviour, suggesting the issue wasn't only order, but how content was structured and navigated. Based on this, we implemented the reorder changes and moved into grouping.

Grouping information to reduce scroll and improve findability

We then grouped related content to help users locate information faster without continuous scrolling. Groupings were based on content that naturally belonged together.

Examples of grouping logic:

  • Property value (Estimate and RV)
  • Property details (Local council data and property history)
  • Suburb information (About the area map, market insights, and suburb overview)
  • Consolidated map-related content into a single primary map to reduce duplication

The redesign

With the new order and groupings in place, we redesigned the page using a tabbed pattern. This allowed the page to retain the same depth of content while reducing overall length and improving navigation. It also gave us clearer behavioural signals (tab clicks) to understand which information users actively engaged with.


Visually, the refresh focused on clarity and consistency with the redesigned homepage and style guide, using spacing, hierarchy, and cleaner font sizing to make dense information easier to scan. The redesigned elements are shown below the results section.

The results

The redesign created a cleaner, more intuitive experience across listings and estimates. We reduced page length by ~30% across desktop and mobile while retaining the same depth of content.

  • +46% call-agent conversion
  • +8% property saves
  • +6% registrations through estimates gate
  • +11% profile completion post-gate
  • +6.9% session duration
  • Bounce rate −42.8%
