Enhancing User Confidence with Badges and Signals in the eBay Cart and Checkout

PROJECT OVERVIEW

eBay, one of the world’s largest online marketplaces, aimed to enhance its user experience by strategically implementing badges and signals in the cart and checkout. My goal was to provide users with valuable, instant information that builds confidence in their purchasing decisions and ultimately drives conversion rates.

ROLE

Lead Product Designer Responsible for the project

TEAM

Supporting designer, two product managers, two engineers, one UX researcher, and one content designer.

METRICS

This implementation achieved a 0.7% lift in site-wide GMV (Gross Merchandise Value) and contributed $140 million in annual incremental GMB (Gross Merchandise Bought) for the cart and $185 million for the checkout. We also saw nearly a ~.05% reduction in cart abandonment rates and an increase in conversion rates, as users felt more confident completing their purchases.

Challenge

eBay’s cart and checkout faced the challenge of providing users with relevant, actionable information without overwhelming them. While signals and badges were present earlier in the shopping funnel, they were missing in the cart, where purchase intent was highest. This lack of clear, contextual details led to hesitation in completing purchases and contributed to a high cart abandonment rate of 90%, significantly above the industry average. My goal was to strike a balance between visibility and subtlety, integrating badges and signals seamlessly to boost user confidence and drive conversions.

design iteration

Brainstorming and Ideation

Collaborative brainstorming sessions were conducted to generate a myriad of badge and signal concepts. Ideas were sketched, prototyped, and presented for internal review, fostering a culture of creative exploration and innovation.


Concept Exploration

Multiple design concepts were explored, each emphasizing different visual treatments, placements, and functionalities. Concepts ranged from subtle badges integrated seamlessly into the interface to prominent signals designed to capture immediate attention.


User-Centered Design

User feedback played a central role in the design iteration process. Prototypes and mockups were subjected to rigorous usability testing, with users providing feedback on clarity, relevance, and visual hierarchy.


Refinement and Consolidation

Iterative cycles of feedback and refinement led to the consolidation of design elements that resonated most strongly with users. This involved fine-tuning color palettes, typography, iconography, and layout to ensure cohesive and intuitive user experiences.

Collaboration with Development Team

Collaboration between the design and development teams was instrumental in translating design concepts into functional, technically feasible solutions that could be seamlessly integrated into eBay's platform.

Cross-functional workshops

I held regular workshops to facilitate open communication and alignment between design and development stakeholders. These sessions fostered a shared understanding of project objectives, technical constraints, and timelines.


Iterative review and feedback

Continuous dialogue between design and development teams facilitated iterative refinement throughout the implementation phase. Design adjustments were made in response to technical constraints or optimization opportunities identified during development.


prototyping and development

Design prototypes were handed off to the development team for implementation. Close collaboration ensured that design specifications were accurately translated into code, with developers providing feedback on feasibility and performance considerations.


quality and assurance

Rigorous testing and QA processes were conducted to ensure the seamless integration of badges and signals across different platforms and devices. This involved cross-browser testing, performance optimization, and accessibility audits to guarantee a consistent and robust user experience.


The collaborative synergy between design and development teams ensured the successful execution of badge and signal implementations, maintaining fidelity to design intent while adhering to technical requirements.

Testing and Optimization

The testing and optimization phase was characterized by a data-driven approach to evaluate the effectiveness of badge and signal placements and designs, iteratively refining the user experience based on user feedback and analytics insights.

a/b testing

Variations of badge and signal placements, designs, and messaging were subjected to rigorous A/B testing. This involved randomly assigning users to different test groups and measuring key performance metrics such as conversion rates, engagement, and user satisfaction.


analytics analysis

Granular analysis of user behavior data provided quantitative insights into the impact of badge and signal implementations. This included tracking user interactions, click-through rates, and cart abandonment metrics to identify areas of optimization.


user feedback loops

Ongoing solicitation of user feedback through surveys, interviews, and usability testing provided qualitative insights into user perceptions and preferences. Feedback was systematically incorporated into design iterations to address pain points and enhance user satisfaction.


continuous iteration

The testing and optimization process operated in a continuous feedback loop, with insights gleaned from A/B testing and user feedback informing iterative design refinements. This agile approach enabled rapid experimentation and adaptation to evolving user needs and market dynamics.


By harnessing the power of data-driven insights and iterative refinement, the design team ensured that badge and signal implementations were continuously optimized to maximize user engagement, conversion rates, and overall satisfaction within the eBay shopping cart and checkout experience.

Lessons Learned

Iterative Design Process

Our iterative design process, driven by user feedback, involved ideation, prototyping, testing, and refinement across multiple platforms. We discovered that some design tests performed better on iOS than Android or desktop, and vice versa, due to factors like platform-specific user behavior, operating system constraints, and interaction patterns. This insight led us to fine-tune our designs based on the nuances of each platform, ensuring consistency while optimizing the user experience across all devices. This approach not only helped us identify pain points but also allowed us to continuously adapt and improve based on platform performance.
