How a 5‑Iteration Redesign Revitalized 58.com Car Listings

Introduction

This redesign spanned five iterations and six releases over more than a year of research and a six‑month development cycle. The effort combined UI, visual, and interaction design teams to address a fragmented publishing process that had suffered from low conversion after policy changes.

Background

58.com’s second‑hand car app supports “personal” and “free merchant” users. In December 2019 a “real‑car rule” required users to provide name, ID number, and facial or WeChat verification, and made vehicle verification mandatory. This policy improved data authenticity but caused a sharp drop in publishing success rates.

Preliminary Thinking

When the product team received the request, they asked why the publishing flow was so fragile. The “real‑car rule” alone caused a major conversion dip, prompting a broader view of publishing as both a tool and a source of value for the entire platform.

Definition Upgrade

The redesign was re‑defined as an “upgrade of the value system around publishing.” Two intertwined value systems emerged: publishing efficiency (the tool) and display quality (the information presented to users).

Publishing System Upgrade

Entry consolidation : merged normal and “flash sale” publishing entrances, clarified differences, and placed both under the car category header, resulting in higher click‑through rates.

Form depth reduction : collapsed the publishing form from six levels to four, moving photo/video capture to the first page.

Field optimization : categorized fields into essential, useful, and unnecessary; removed six fields, cut mandatory items by twelve, and added six optional useful items.

Real‑car verification streamlining : replaced multiple jump‑outs with a single “one‑click document and photo” step, simplifying user actions and improving backend audit efficiency.

Display System Upgrade

Improving image quality directly increased user attraction and conversion. Tests showed that raising image brightness by 8% yielded a measurable rise in phone inquiries.

Five major image issues were identified: spatial relationship, aspect ratio, lighting, content, and insufficient quantity. Interventions were applied at three stages:

Pre‑publish : pop‑up guidance encouraged users to choose well‑lit environments.

During publish : enforced a 4:3 layout for list/detail images, provided a shortest‑path workflow for multi‑angle shots, and added short‑video guidance.

Post‑publish : displayed upload status, highlighted image problems, and offered tool usage feedback.

Conclusion

Viewing publishing as part of a larger value system led to double‑digit improvements in effective vehicle listings, audit pass rates, and overall publishing success. The systematic upgrades—form redesign, real‑car rule optimization, and image/video quality enhancements—demonstrated the power of holistic, system‑level thinking.
