PROBLEM AREA

Users were dropping off because of long load times between cart and shopping pages

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. While doing that they saw long load times and some eventually dropped off.

As a consequence the company was loosing on average $1M sales yearly. The goal was to increase checkout completion.

TECHNICAL LIMITATION

Long load times couldn't be easily reduced

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.

Long load times when users left entered or left the checkout

Strategy

Giving users a side cart so they can easily review cart contents while browsing and avoid going back and forth between checkout and browsing.

SOLUTION

The side-cart : Giving quick access to the cart

Through brainstorming with stakeholders and looking at 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.

DESIGN DECISIONS AND TRADEOFFS

Excluded Express Checkouts CTAs from the side cart

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. Having these options only presented at checkout was the trade-off I decided to go with.

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
More space for products - easier decision making
Less cluttered- easier decision making
One more click and page load before user can use express checkout

Placed specs behind a tooltip

Based on user insight and data I knew users usually know the specs they need and it's unlikely for users to add the same product twice to cart with different specs. so specs are secondary information that can be hidden behind a tooltip. Also user testing showed users were easily able to find product specs by pressing on the tooltip.

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
Too many focus points, not easy to make a decision

IMPACT

Fewer drop offs, More sales

The streamlined side cart experience (designed for speed and clarity) made it easier for users to review their selections and proceed with confidence.

Cart drop-offs decreased, and while fewer users started checkout, a higher percentage completed it.

I lead the designs for a revamp of the cart/checkout experience that included 3 flows of buying, selling and trading. Below you can find some designs from the buying experience.

Opportunity: How might we reduce cart drop offs

Users were dropping off because of long load times between cart and shopping pages

Users dropping off because of long load times between cart and shopping pages

Observing user behavior showed us a common pattern:

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

This back and forth created friction for users and led to high drop offs from the flow.

So we asked: how might we support decision-making earlier, without disrupting the shopping flow?

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. While doing that they saw long load times and some eventually dropped off.

Technical limitation: Long load times couldn't be easily reduced

This back and forth created friction for users and led to high drop offs from the flow.

This could not be easily fixed because the checkout was part of a different platform integration.
