Ecommerce Accessibility: How to Make an Online Store More Accessible

This guide explains how to make an online store more accessible, focusing on WCAG 2.1 AA requirements, product pages, checkout and ecommerce-specific testing. It includes a practical QA checklist and common fixes for stores.

Ecommerce store website accessibility means designing product pages, navigation and checkout so people with disabilities can buy without barriers. This guide gives concrete, store-specific steps you can use today and a testing checklist built for online shops.

Why accessibility matters for ecommerce

Accessible stores reach more customers and reduce abandoned carts. Accessibility helps keyboard users, people with low vision, screen reader users and customers with cognitive differences. It also lowers support calls and improves SEO because content is clearer for search engines.

WCAG basics for online stores

Use WCAG 2.1 level AA as the baseline. That covers text contrast, keyboard access, form labels and clear error messages. Focus on these technical areas first so features behave predictably across devices and assistive tech.

Contrast and text

WCAG AA contrast ratios to target:

Text size Minimum contrast ratio
Normal text 4.5:1
Large text (18pt or 14pt bold) 3:1

Keyboard access

Every interactive element must be usable with Tab, Enter and Space. Ensure focus order matches visual order. Use a visible focus style that meets contrast requirements.

Labels, semantics and ARIA

Use native semantic HTML where possible. Add explicit label elements for inputs. Avoid ARIA unless native elements cannot provide the required behaviour. When you use ARIA, prefer attributes like role=“alert”, aria-live=“polite”, aria-expanded and aria-controls to describe state.

Product pages: the most critical area

Product pages need special attention because they drive purchases. Make selection, price and delivery details clear to assistive tech and keyboard users.

Images and alternative text

Provide descriptive alt text for product images. For decorative images, use empty alt text. For multiple product images, include the view in the description, for example “blue denim jacket, front view”.

Variant selectors and swatches

Variant controls must announce the current choice. Use native select when possible. If you build a custom control, implement a listbox pattern with role=“listbox”, manage keyboard arrows and set aria-selected on active options.

Prices, discounts and stock status

Announce price and availability near the product title. For dynamic changes, update a live region such as aria-live=“polite” so screen reader users hear price updates when options change.

Reviews and ratings

Structure reviews with headings for each review and include an accessible summary for ratings. Use semantic lists for multiple reviews so screen readers present them clearly.

Add a visible skip link to jump to main content. Ensure the site search has an accessible label and predictable focus behaviour. Use correct heading order for page structure so users can scan quickly.

Carousels, modals and overlays

Carousels should pause automatic rotation and allow keyboard control. When opening a modal, move focus into it and trap focus while it is open. Return focus to the opening control when closing.

Cart and live updates

Use ARIA live regions for cart updates. For example, when an item is added, update a role=“status” element with a short message. Ensure this does not interrupt ongoing tasks for screen reader users.

Checkout and payments

Checkout is a high-friction area. Reduce friction with clear labels, logical tab order and immediate validation.

Forms and validation

Label every input. Place error messages next to the input and connect them using aria-describedby. Use clear icons plus text for error state so users who cannot see colour still understand the problem.

Third-party payment widgets

Many stores embed hosted payment fields. Test these widgets with a keyboard and screen readers. If a provider cannot meet accessibility needs, document the limitation and offer an accessible alternative, for example a different payment method or phone order.

Media, video and PDFs

Provide captions for videos and a transcript for longer content. For PDFs, ensure tagged, structured text. Avoid relying on images of text for essential information like instructions or return policies.

Widgets, third-party content and overlays

Third-party chat, reviews and recommendation widgets often break accessibility. Treat them as part of your accessibility scope. If a widget cannot be fixed, remove it or provide an accessible fallback.

Testing and QA checklist for ecommerce (practical step-by-step)

This checklist is designed for regular releases and for purchase-critical pages.

  1. Keyboard only: Navigate header, product lists, product pages, cart and checkout using Tab, Shift+Tab, Enter and Space. All controls must be reachable and usable.
  2. Screen reader smoke test: Open a product page with NVDA or VoiceOver. Confirm product title, price and add-to-cart control are announced in the top content.
  3. Contrast check: Run automated contrast checks for product titles, buttons and labels and spot-check critical pages against the ratios above.
  4. Form validation: Submit checkout with missing data and confirm errors are announced and linked to inputs using aria-describedby or native associations.
  5. Dynamic updates: Change product variants and confirm the page announces price or stock changes via an aria-live region.
  6. Widgets: Disable third-party widgets and confirm the page still provides essential purchase flows.
  7. Mobile and zoom: Test at 200 percent zoom and on a narrow viewport to ensure no content is lost.
  8. Automated scans: Run an accessibility scanner such as axe or WAVE, then triage results into the QA backlog for manual review.

Common pitfalls and how to fix them

  • Missing alt text: Fix by writing concise alt attributes that describe the product view.
  • Custom controls without keyboard support: Replace or enhance them to support arrow keys, Enter and Space.
  • Unlabelled form fields: Add label elements and connect with for attributes.
  • Relying only on overlays: Do not treat overlays as a full accessibility solution. They may fail screen readers and keyboard users.

In the UK, the Equality Act 2010 is relevant to access for customers with disabilities. Many retailers treat WCAG 2.1 AA as the practical standard to reduce legal risk. Check with legal counsel for how the law applies to your organisation and contracts with third-party vendors.

Prioritising fixes: what to do first

Start with pages that drive revenue: home, category, product, cart and checkout. Fix issues that block purchase flows such as missing labels, unreachable add-to-cart buttons and inaccessible payment widgets. Then address content like help pages and marketing banners.

Next steps

Build accessibility into design and development processes. Add an accessibility gate to releases for product and checkout pages. Train designers on colour contrast and components. Make the testing checklist routine for new features.

If you want, use the checklist above to run a focused audit of your top 10 revenue pages. Small fixes often reduce support calls and improve conversion.
