Boost revenue with accessible ecommerce checkout optimization

Do you ever think about the vastly different shopping experiences various generations grew up with? Baby Boomers, born between 1946 and 1964, came of age through an era dominated by in-store shopping. For them, a frictionless customer experience meant in-stock items and helpful, efficient store staff.

Gen Z, born roughly between 1995 and 2010, has lived a very different consumer experience. By the time this generation was old enough to make purchases on their own, online shopping was the norm. They have high expectations for endless choices, one-click purchasing, and same-day delivery (and they clearly aren’t alone).

Gen Z’s criteria for frictionless experience is similar to that of their grandparents: get me through the process fast and without issues. Only now it’s called “e-commerce checkout optimization.”

The mobility-accessibility connection

Although Baby Boomers and Gen Z were born decades apart, both groups now use mobile devices to shop. In the U.S., 48% of users aged 65+ regularly use smartphones for online shopping, with 11% doing so at least once weekly. The mobile shopping percentages increase dramatically when Gen X, Millennials, and Gen Alpha enter the picture.

Our collective growing appetite for mobile ecommerce is associated with impressive revenue numbers. Worldwide mobile ecommerce sales revenues were $2.07 trillion in 2024. They are projected to jump to $3.02 trillion by 2027. It’s an era where seamless mobile checkout UX is a major competitive advantage.

Seamless is a critical word here. Revenue leakage will occur if ecommerce checkout optimization isn’t prioritized for every customer. And this includes people with disabilities.

People with disabilities are part of mobile shopping demographics

Disabilities impact people across every age demographic, and that impact may be greater than many business leaders realize.

There are an estimated 1.85 billion people living with disabilities globally, along with 3.3 billion people who care a lot about what happens to them. The combined disposable income of this group is in the tens of trillions of dollars.

What does “disabilities” actually mean?

It’s important to remember that disabilities take many different forms, some of which aren’t necessarily top of mind:

  • Some people are born with disabilities while others acquire them through aging, illness, or injury

  • Some disabilities are visible (e.g., a person who relies daily on a wheelchair) and others aren’t (e.g., a person living with autism or Alzheimer’s disease)

  • Many disabilities are permanent (e.g., being totally deaf), but others are temporary (e.g., having an ear infection), or even situational (e.g., having trouble hearing a conversation in a noisy restaurant)

  • Lots of people who benefit from accessibility don’t identify as disabled. This is quite common in the 65+ age group where declining vision, hearing, and mobility present challenges, but aren’t labelled as “disabilities”

These many nuances add up to one big truth: creating frictionless customer experiences in mobile shopping means planning for accessibility. Businesses that don’t will inadvertently shut a large proportion of customers out of their mobile experiences and leave lots of money on the table.

The issue with prioritizing compliance over usability

It’s tempting to think accessibility is covered in your mobile ecommerce app if you’re checking the boxes associated with legislation like Web Content Accessibility Guidelines (WCAG), the European Accessibility Act (EAA), and the Americans with Disabilities Act (ADA).

Compliance is critical and can save your organization from being named in expensive lawsuits. But compliance alone doesn’t solve the issue of making mobile apps more usable for people with disabilities.

Among Fable’s Community of assistive technology users, mobile device use is common. 41% report using their mobile devices for more than 4 hours a day, and 23% use them between 2 – 4 hours per day.

Here are the top three barriers reported in their mobile experiences:

  • Unlabelled buttons or links (60%)
  • Small buttons or links (35%)
  • Requiring gestures to interact (35%)

They also flagged barriers around parts of the screen being blocked, a lack of error messages, inability to resize text, and inability to pinch and zoom. These experiences aren’t confined to a small community of users. They impact the larger population of people with disabilities every day.

Mobile shopping apps scored the lowest in accessibility

The potential to increase sales revenues is strong for businesses that design truly accessible apps prioritizing positive app UX and checkout optimization for people with disabilities.

Unfortunately, the State of Mobile App Accessibility Report analysis found shopping apps were the biggest under-performers, receiving a Poor Industry Accessibility Score (41). The next-lowest score was Fitness apps (50) and the highest score was Food & Delivery (61).

A scale measuring Industry Accessibility Score shows that Shopping earned a Poor score of 41.

What were the biggest accessibility fails in shopping apps?

The table below details accessibility areas assessed in the report, performance issues uncovered, and the impacts on people with disabilities.

5 shopping app accessibility failures uncovered in the report

Assessment Performance issue User impact
Screen orientation 88.9% of app screens lack support for both portrait and landscape orientations. People with motor disabilities can’t always physically reposition their mobile device.

Screen magnifiers or zoom functions often work better in landscape mode.

Users with cognitive disabilities may find it easier to process information in a wider format.

Screen reader usability 91.1% of shopping app screens had name, role, and value issues, severely impacting screen reader users.
88.9% of screens prevent users from interacting with all actionable items using a screen reader, and 68.9% contain elements that aren’t focusable.
Many shopping apps are essentially unusable for visually impaired people.
Alternative navigation 77.8% of app screens have focus order issues, disrupting keyboard and assistive technology navigation.
42.2% of screens have issues with actionable elements being reachable for alternative navigation users.
Navigation is disrupted or impossible for people using alternative navigation assistive technologies.
Information conveyance 60% of app screens have alt-text issues, hindering screen reader users’ understanding of product visuals. People with vision disabilities or who are totally blind rely on visual information to make purchase decisions. This is a major barrier to overall app usability.
Font scaling 71.1% of app screens lack full font scaling support.

Of those with partial support, 55.6% exhibit layout issues and information loss.

Support for font scaling in iOS apps was particularly bad, with only one out of five top apps fully supporting it.

Small text becomes unreadable for users with low vision or age-related vision decline, and zooming isn’t always a workaround as it can cut text off or break the app layout

People with cognitive disabilities, like dyslexia or ADHD, may experience cognitive load and fatigue if they can’t adjust text size for better readability.

The high costs associated with low usability

Imagine trying to decide whether to add a shirt to your cart when you have zero information on the color or style? It’s no wonder the widespread lack of accessibility in mobile shopping apps is often a deal-breaker for people with disabilities. No matter how much a person with disabilities wants to shop with your brand, these unusable mobile experiences will often lead to involuntary churn.

Issues from the get-go

Product details are essential to creating frictionless customer experience at the beginning of a mobile ecommerce session. Nobody wants to buy something they don’t fully understand, so detailed image alt text is essential. According to Melody S., a screen reader user and accessibility tester, “Many image descriptions are barely enough to indicate that it could be a product.”

Additionally, every icon in the UX needs a text label that’s visible or hidden for screen readers. Customers can’t complete actions and get to the checkout stage if they can’t easily figure out what the various buttons do.

63.3% of home screens in shopping apps received a Poor or Failing grade from The State of Mobile App Accessibility Report. In practical terms, this means these apps introduced immediate barriers for users with disabilities.

This problem carries over into product details screens, where over three-quarters (76.7%) deliver a Poor or Failing experience.

Poor checkout UX leads to cart abandonment

Accessible mobile ecommerce checkout optimization has feedback baked in. If a user is relying on screen reader technology to tell them whether an item has been successfully added to their cart, confirmation is essential.

Even if the actual checkout experience is smooth, a lack of clarity around cart contents means a potential customer is highly likely to abandon their online cart before they reach that step. And shopping cart abandonment cost is a $260 billion dollar problem.

A competitor who has prioritized accessible ecommerce checkout optimization is just a click away. Even if a competitor doesn’t scoop up your customer, they may decide shopping with your brand through their mobile device is too frustrating. This is when they head in-store to shop, where your overhead and staffing costs are high. This decision not only drives down your margins, it can reduce basket size.

“[When I placed an item in my cart] no notification appeared to confirm that an item had been added. The screen abruptly changed, taking me back to the item list. This made me lose my orientation.”

It’s time to reframe accessibility as “usability for all”

Accessibility in mobile ecommerce apps matters more than ever to your brand’s reputation and revenue. The accessibility of apps and mobile sites heavily influences the purchasing decisions of people with disabilities. Their experiences, in turn, heavily influence the brand perceptions of many people within their inner circles. This translates into a lot of purchasing power that can work for or against a brand.

Today, building accessible apps for mobile ecommerce is about more than checking compliance boxes or focusing on after-the-fact fixes. It’s about:

  • Making mobile apps enjoyable and usable for people with disabilities from the start

  • Bringing their perspectives into the UX research and design process, early and often

  • Giving teams permission to start small so they don’t get overwhelmed (Think: supporting a user’s chosen font size across an entire mobile app experience)

Prioritizing the usability of mobile apps for people with disabilities early and often won’t slow time to market. In fact, it will prevent both costly accessibility remediation work and revenue leakage from poor UX. Learn more about the ROI of investing in accessibility and usability.
