Context

GolfAvenue in an online marketplace selling new and used golf equipment. The website was built fast and had many usability issues. Over the course of a year I designed and proposed improvements to the checkout experience and worked closely with the team to implement changes.

This case study is about part of the revamp, were I discovered a friction point and designed a side-cart to improve checkout completion.

The company was estimating an annual $1M revenue loss from cart drop offs.

After optimizing the checkout experience and seeing results, we noticed there's still a lot of drop offs from cart to checkout. So it was time to focus on the cart.

What we initially assumed

What we initially assumed

We initially assumed users are dropping off because the cart looked cluttered and overwhelming

Cleaning up and polishing the components was part of the plan however, looking into user behaviour revealed more.

The discovery

The discovery

Looking at heatmaps, I discovered users leaving the cart to go back to the shopping journey

Shoppers were adding all their “maybe” options to the cart, then navigating back and forth between the cart and product pages to compare, delete, and rethink. The real issue was the journey.

User frustrations

User frustrations

Users were dropping off because of long loading times

When users went back and forth between cart and product listing pages, they faced long loading times and some of them dropped off because of the frustration.

The checkout was built on a different platform than the rest of the website. Because of this, moving between the site and the checkout was sometimes slow, and it wasn’t something we could easily fix.

Strategy:

Let shoppers review and edit their cart without leaving the shopping experience.

The Solution

The Solution

The Side cart : Giving quick access to the cart

Through brainstorming with stakeholders and analyzing competitors, we introduced a Side cart that could be opened at any time, giving users the opportunity to check and adjust the contents of their cart without leaving the shopping journey. So they could move to checkout only when their decision was made.

Before: 10s on average load time

Design Decisions and Trade-offs

Design Decisions and Trade-offs

Prioritized cart decisions on mobile.

After analyzing edge cases on mobile, I chose to leave out express payment options to keep the side cart focused on decision-making. Including them would have required adding coupon code fields as well. That was too much for a clean mobile experience. I chose to keep the side cart focused on reviewing and editing items, leaving express checkout for the full checkout page.
This added an extra step for shoppers who wanted express payment, but kept the side cart simpler and better suited to its main purpose.

Option 1 Express checkout available on the side cart
Option 1 Express checkout available on the side cart

Not enough space for more than 2 products

Cluttered interface

Option 2: Express checkout not available on the side cart
Option 2: Express checkout not available on the side cart

More space for products - easier decision making

Less cluttered- easier decision making

One more click and page load before user can use express checkout

Validating Assumptions

Validating Assumptions

Placed specs behind a tooltip

Based on user insights and data, I hypothesized that club specifications didn’t need to be visible at all times, since users were unlikely to add the same club to their cart with different specs. I proposed making specs secondary information, accessible through a tooltip.

I ran a usability test on maze with 12 users asking them to find "TaylorMade Qi10 regular. left-handed, New" on mobile, in a side cart filled with 4 items. The option with tooltips performed better.

Option 1:Specs available when clicking on the tooltips

Less cluttered

Focus on product title and decision making

Option 2:Specs available at all times

Cluttered interface

Less cluttered- easier decision making

Too many focus points, not easy to make a decision

Usability tests results: 1 extra click is better than a cluttered interface
