ADA Website Accessibility: What Small Businesses Need to Know

An inaccessible website can prevent people with disabilities from accessing a business’s products and services. Common barriers include missing image descriptions, videos without captions, poor color contrast, inaccessible forms and pages that cannot be operated with a keyboard.

Courts have taken different approaches to applying the Americans with Disabilities Act to websites. However, the Department of Justice maintains that businesses open to the public must make their online goods and services accessible.

Private businesses do not currently have one detailed federal technical standard under Title III. Nevertheless, the Web Content Accessibility Guidelines 2.1 Level AA, or WCAG 2.1 AA, are widely used as a practical accessibility benchmark.

The Four Principles of an Accessible Website

WCAG organizes accessibility around four principles known as POUR.

Perceivable

Users must be able to perceive the information presented. Important practices include:

Adding alternative text to meaningful images
Providing captions and transcripts for media
Maintaining sufficient color contrast
Allowing users to resize text
Avoiding instructions that depend only on color

Operable

Users must be able to control and navigate the website.

Make all functions available by keyboard
Provide visible keyboard focus
Use descriptive page titles and headings
Give users enough time to complete tasks
Avoid flashing content that may trigger seizures
Include ways to bypass repeated navigation

Understandable

Content and controls should behave predictably.

Use clear language and consistent navigation
Identify the page’s primary language
Label forms and explain required information
Provide useful error messages
Allow users to review important submissions
Use icons and controls consistently

Robust

Website content should work with different browsers and assistive technologies.

Use valid semantic HTML
Give controls accessible names and roles
Ensure forms work with screen readers
Announce important status and error messages
Avoid custom components that assistive technology cannot interpret

ADA Website Accessibility Checklist

Small businesses should prioritize the parts of the website customers need to complete important tasks.

Add descriptive alt text to meaningful images
Caption videos and provide transcripts for audio
Check text and interface color contrast
Make menus, forms and checkout usable by keyboard
Use a logical heading structure
Label every form field clearly
Provide instructions for correcting errors
Avoid links labeled only “click here”
Make downloadable documents accessible
Test zoom and text resizing
Include an accessible way to report problems
Review third-party booking, payment and ordering tools

Pay particular attention to the homepage, contact page, product pages, account login, reservations, forms and checkout process.

How to Test Website Accessibility

Start with an automated accessibility scan, but do not rely on it alone. Automated tools detect only some WCAG failures and cannot determine whether the entire customer experience is accessible.
A stronger review combines:

Automated testing to identify common technical errors
Keyboard testing to confirm every function works without a mouse
Screen-reader testing to evaluate navigation, labels and announcements
Manual review of headings, forms, contrast and content clarity
User testing involving people with disabilities when possible

The W3C WCAG Quick Reference provides detailed success criteria and implementation guidance.

Build Accessibility Into Website Maintenance

Accessibility is not a one-time project. New pages, products, plugins and third-party tools can introduce additional barriers.
Businesses should establish a simple maintenance process:

Require accessibility in developer and vendor contracts
Test new features before publication
Recheck important pages periodically
Train employees who publish website content
Record audits and completed corrections
Respond quickly when a user reports a problem
Obtain legal advice after receiving an ADA demand letter or lawsuit

An accessibility statement may explain the business’s commitment and provide a way to request assistance, but it does not replace an accessible website.

Key Takeaways

Small businesses should treat website accessibility as part of customer service, risk management and routine website maintenance.

WCAG 2.1 AA provides a practical framework built around four requirements: content must be perceivable, operable, understandable and robust. Businesses should begin with high-traffic customer journeys, combine automated and manual testing and correct barriers according to their impact on users.

The Department of Justice offers additional guidance on web accessibility and the ADA.
