April 23, 2025

E-commerce websites are prime targets for accessibility lawsuits. In recent years, online retailers have faced thousands of ADA-related legal claims, with plaintiffs successfully arguing that inaccessible websites discriminate against people with disabilities. Beyond legal risk, inaccessible e-commerce costs retailers billions in lost revenue from customers who can't complete purchases.

This guide covers e-commerce-specific accessibility requirements, common issues in retail websites, and implementation strategies for compliant online stores.

Why E-commerce Accessibility Matters

Legal Landscape

Retail e-commerce leads accessibility litigation:

Lawsuit trends:

  • E-commerce accounts for majority of ADA website lawsuits
  • Average settlement: $15,000-$50,000
  • Serial plaintiffs target multiple retailers
  • Class actions can reach millions

Legal basis: Courts increasingly interpret ADA Title III to cover websites of businesses that serve the public.

Market Opportunity

Accessibility expands your customer base:

Disability market:

  • 61 million Americans have disabilities
  • $490 billion annual disposable income
  • Strong brand loyalty to accessible businesses
  • Influences $8 trillion global market including friends/family

Situational users:

  • Parents holding children
  • Users in bright sunlight
  • Temporary injuries
  • Aging population with declining vision

Conversion Impact

Accessibility improves e-commerce metrics:

| Metric                | Typical Improvement |
|-----------------------|---------------------|
| Conversion rate       | 15-35% increase     |
| Cart abandonment      | 20-30% reduction    |
| Return rate           | 10-20% reduction    |
| Customer satisfaction | 25-40% increase     |

E-commerce Accessibility Challenges

Product Discovery

Users must find products effectively:

Search functionality:

  • Autocomplete accessibility
  • Search results structure
  • Filter and sort controls
  • Voice search alternatives

Navigation:

  • Mega menu accessibility
  • Category hierarchies
  • Breadcrumbs
  • Mobile navigation

Product Information

Product pages present unique challenges:

Images:

  • Product photos need descriptive alt text
  • Image zoom functionality
  • 360-degree views
  • Color variants

Specifications:

  • Complex data tables
  • Size charts
  • Comparison features
  • Technical specifications

Purchase Flow

Checkout is where accessibility failures cost sales:

Shopping cart:

  • Add/remove functionality
  • Quantity updates
  • Cart totals
  • Applied discounts

Checkout:

  • Form accessibility
  • Address validation
  • Payment processing
  • Order confirmation

Shopify-Specific Considerations

Theme Selection

Choose accessible themes:

  • Dawn (Shopify 2.0 default) - generally accessible
  • Sense - accessibility-focused design
  • Custom themes - require audit

Common Shopify Issues

Product variant selectors: Many themes use inaccessible dropdowns or swatches.

Quick add to cart: Modal implementations often lack focus management.

Mega menus: Complex navigation often keyboard-inaccessible.

Image zoom: Lightbox implementations commonly trap focus.

Shopify Accessibility Apps

Evaluate carefully—many overlay-based apps don't provide true compliance. Look for apps that modify source code rather than overlay widgets.

Testing E-commerce Accessibility

Critical User Journeys

Test complete flows:

  1. Product discovery

- Search for product - Browse categories - Use filters - View search results

  1. Product evaluation

- View product images - Read descriptions - Check specifications - Select variants

  1. Purchase

- Add to cart - Modify cart - Complete checkout - Receive confirmation

Taking Action

E-commerce accessibility protects against legal risk while expanding your customer base. Focus on critical purchase paths first—product pages, cart, and checkout—then work outward to navigation and search. Continuous monitoring catches regressions before they impact customers.
