What Is Web Accessibility and Why Does Your Business Need It?

Web accessibility means designing and building websites so that people with disabilities can perceive, understand, navigate, and interact with them effectively. It covers a broad spectrum of disabilities including visual, auditory, motor, cognitive, and neurological conditions.

At its core, web accessibility follows the Web Content Accessibility Guidelines (WCAG) 2.1, published by the World Wide Web Consortium (W3C). The most commonly referenced conformance level is AA, which strikes a practical balance between usability and implementation effort. WCAG 2.1 AA is the standard that most laws and regulations reference when defining what an accessible website looks like.

The Legal Landscape: Why Compliance Is Not Optional

Accessibility is not just a best practice. It is increasingly a legal requirement.

• ADA Title III covers private businesses that serve the public. Federal courts have consistently ruled that websites qualify as places of public accommodation under the Americans with Disabilities Act. In 2024 alone, over 4,100 ADA-related web accessibility lawsuits were filed in the United States.
• Section 508 of the Rehabilitation Act requires federal agencies and organizations receiving federal funding to make their electronic and information technology accessible. If your business contracts with any government entity, Section 508 compliance is mandatory.
• The European Accessibility Act (EAA), which takes full effect in June 2025, requires businesses selling products and services in the EU to meet accessibility standards. This applies to e-commerce websites, banking services, transport ticketing, and more, regardless of where the business is headquartered.
• State-level laws are expanding too. California's Unruh Civil Rights Act has been used extensively in web accessibility litigation, and New York courts regularly hear cases related to digital accessibility under state and city human rights laws.

The Business Case for Accessibility

Beyond legal compliance, accessibility directly impacts your bottom line.

Reach a larger audience

Over one billion people worldwide live with some form of disability. In the United States alone, 61 million adults have a disability. When your website is inaccessible, you are excluding a significant portion of potential customers.

Improve your SEO

Many accessibility best practices overlap with search engine optimization. Proper heading structure, descriptive alt text, semantic HTML, and fast load times all contribute to better search rankings. Google has explicitly stated that accessible websites tend to rank higher.

Reduce legal risk

The average settlement for an ADA web accessibility lawsuit ranges from $5,000 to $150,000, not including legal fees. Proactive compliance is significantly cheaper than reactive litigation.

Build trust and brand reputation

Demonstrating a commitment to accessibility signals that your business values all customers. This builds loyalty and positive brand perception, particularly among younger demographics who prioritize inclusive companies.

Common Accessibility Issues and How to Spot Them

Most websites have accessibility issues that are straightforward to identify and fix.

• Missing or inadequate alt text. Images without descriptive alternative text are invisible to screen reader users. Every meaningful image needs alt text that conveys its purpose. Decorative images should use empty alt attributes to be skipped by assistive technology.
• Insufficient color contrast. Text must have a contrast ratio of at least 4.5:1 against its background for normal text, and 3:1 for large text (18px bold or 24px regular). Low contrast makes content unreadable for users with low vision or color blindness.
• Missing keyboard navigation. Every interactive element, including links, buttons, forms, and menus, must be operable with a keyboard alone. Many users cannot use a mouse due to motor disabilities. Test by pressing Tab to move through your page and Enter or Space to activate elements.
• Missing form labels. Form inputs without associated labels leave screen reader users unable to understand what information is being requested. Every input, select, and textarea element needs a programmatically associated label.
• Auto-playing media. Videos or audio that play automatically can be disorienting for users with cognitive disabilities and interfere with screen readers. Always provide controls to pause, stop, or adjust media volume.
• Missing page language. The HTML lang attribute tells screen readers what language to use for pronunciation. Without it, screen readers may mispronounce content or fail to render it correctly.

How to Get Started with Web Accessibility

Improving accessibility does not require a complete redesign. Start with these steps.

1. Run an automated scan. Tools like HandyPal's accessibility audit can identify the most common WCAG violations on your site in minutes. Automated testing catches roughly 30 to 50 percent of accessibility issues.
2. Fix the critical issues first. Focus on the issues that affect the most users: missing alt text, broken keyboard navigation, insufficient contrast, and missing form labels. These changes often require minimal development effort.
3. Test with assistive technology. Use a screen reader like NVDA (free, Windows) or VoiceOver (built into macOS and iOS) to experience your site as a blind user would. Navigate with your keyboard only. These manual tests reveal issues that automated tools miss.
4. Add an accessibility widget. An accessibility overlay widget gives visitors immediate control over their experience, including font size, contrast, cursor size, and reading aids. While widgets complement but do not replace structural fixes, they provide an immediate improvement layer.
5. Establish an ongoing process. Accessibility is not a one-time project. Content updates, new features, and design changes can introduce new issues. Schedule regular audits and include accessibility checks in your development workflow.

Tools for Accessibility Testing

Several tools can help you assess and improve your website's accessibility.

• HandyPal Accessibility Audits provide comprehensive WCAG 2.1 AA testing with detailed reports and fix guidance. You get unlimited scans and side-by-side comparison to track progress.
• WAVE (Web Accessibility Evaluation Tool) is a free browser extension that provides visual feedback about the accessibility of your web content.
• axe DevTools by Deque is a browser extension popular with developers that integrates into browser developer tools for quick testing during development.
• Lighthouse, built into Chrome DevTools, includes an accessibility audit section that checks against a subset of WCAG criteria.

Getting accessibility right is not just about avoiding lawsuits. It is about building a web that works for everyone. The businesses that prioritize accessibility today are building a competitive advantage that compounds over time.
