eBay Price Guide

A trading card price tracking tool, leveraging data to build customer confidence.

Project Overview

Have you ever wondered how much your old Pokemon cards are worth?

I designed a scalable 0>1 experience that allows customers to view real-time market values of their trading cards on eBay for the first time.

ROLE

Product design lead working directly with UX Researcher, Product Manager, and Engineering team, while consulting other designers.

TIMELINE

First launched in July 2021 with incremental improvements until I left the company in April 2023.

OUTCOMES

- 4x yearly revenue goal
- 40% Retention
- 500k> unique users

Problem Space

eBay is the world's biggest trading card marketplace with over $4 billion in annual trading card sales. However, people couldn't find the value of trading cards on eBay. This led to two problems:

1. Customer Problem

Customers didn't know how much their trading cards were worth on eBay. This led users to search for an "estimate" by digging through past eBay transactions, or by migrating to the competition.

2. Business problem

Competitors were integrating eBay sales data into their own marketplaces, and presenting in a much more digestible way to attract customers away from eBay.

Project Goal

We needed to provide customers reliable and accurate values for their trading cards on eBay. By presenting this data in a transparent and actionable way we're building trust by pulling back the curtain and allowing customers to buy and sell with confidence.

This will, in turn, lead to an increase in revenue and retention.

Key insights from research

We kicked off the project with a user research study testing high-level concepts. Here's what we learned:

🎯

Specific workflows

Customers relied on a search-based workflow, suggesting that our feature had to fit into their mental model.

⏱️

Customers search iteratively

Pricing data is only helpful when searches become specific, so the tool needs to be configurable.

🎢

Volatile market

Understanding trending prices is important as card prices fluctuate rapidly.

💾

Untrustworthy data

eBay data perceived as untrustworthy because of "fake listings" and miscategorized items.

Personsas

Flipper

Higher number of low value cards. Looks to make profit and likes to trade quickly and often.

Enthusiast

May have high or low value cards. Driven by a desire to purchase cards that fuel a feeling or completion or nostalgia.

Investor

Deals with mostly high value cards. Willing to hold onto cards for a long time to make the most profit.

Final design

Search-based workflows

Our customers told us that they were used to a Search-based workflow. So, working with partners on the Search team, we implemented an entry-point to a distinct Price Guide page directly from trading card search results.

Configurability

Customers can search for cards iteratively by either using the search bar at the top of the page, or by using the filters to account for professional grade, variation, and buying format.

Show me the money

The Price Guide provides customers with an anchoring price metric based on eBay transaction data. Customers can view how this metric has trended over time to better understand market volatility.

Building Trust

Customers were skeptical of eBay data. To build trust, customers can view the recently sold items that make up the data powering the pricing metrics. In addition, they are able to manually remove listings they themselves deem as outliers.

Expanding across the ecosystem

The new price trend graph and value cluster components were designed to flex and scale across eBay. I aligned the component design with other design stakeholders, and then worked with the Design Systems to make them available for anyone to use.

Putting it all together

I made a fully functioning interactive prototype, working with a motion designer to create a demo video that highlights the entire experience so we could gain alignment, communicate functionality, and enhance understanding.

Outcomes

We launched the eBay Price Guide in July of 2021. For the first time ever, users could get a value of their trading cards on the eBay platform.

Debrief

Our team had a debriefing session after launch. Team members expressed frustration over shifting executive priorities and technical issues being discovered late during the design process. This led to frustrating churn between design, engineering, and product teams.

Ultimately, we were able to get support for improving the experience after the Beta was launched. This is a credit in particular to my product partner who really championed our cause with senior product leadership.
