Website ADA compliance is no longer optional for businesses that interact with the public. It is a legal requirement, a business advantage, and a measurable SEO signal — all at once.
The Legal Landscape
The Americans with Disabilities Act (ADA), passed in 1990, prohibits discrimination against individuals with disabilities in all areas of public life. Courts have consistently ruled that websites qualify as "places of public accommodation" under Title III of the ADA — meaning they must be accessible to people with disabilities.
ADA-related web accessibility lawsuits have increased every year since 2018. In 2023, over 4,500 federal ADA website cases were filed. The target is not just Fortune 500 companies — small and medium businesses are regularly sued, and settlements typically range from $5,000 to $100,000+, plus legal fees and required remediation.
The most commonly cited violations in lawsuits include: missing alt text on images, insufficient color contrast, non-keyboard-navigable menus, forms without proper labels, and videos without captions.
Who Is Affected?
Approximately 26% of U.S. adults have some type of disability. Of those, roughly 8.1 million have a visual disability, 7.6 million have a hearing disability, and millions more have motor impairments that affect how they use a mouse or keyboard. A non-compliant website is invisible or unusable to a quarter of your potential market.
The WCAG Standard
The Web Content Accessibility Guidelines (WCAG) 2.1 is the internationally recognized standard for web accessibility. It is organized around four principles — content must be Perceivable, Operable, Understandable, and Robust (POUR). Level AA compliance is the legal benchmark courts and regulators use.
Key Level AA requirements include: all images have descriptive alt text, color contrast ratio of at least 4.5:1 for normal text, all interactive elements are reachable via keyboard, form inputs have associated labels, and error messages are clearly identified and described.
The SEO Connection
Many accessibility best practices are also SEO best practices. Alt text helps screen readers understand images — and helps Google index them. Proper heading structure (H1, H2, H3) creates a logical document outline that both screen reader users and search crawlers navigate. Fast load times benefit users with slower connections (often correlated with older assistive technology) and improve Google Core Web Vitals scores. The overlap is significant enough that accessibility improvements frequently produce measurable ranking improvements.
How Untap Web Handles Compliance
Accessibility is not bolted on at the end of our process — it is built in from the component level. Every image receives meaningful alt text. Color contrast is validated against WCAG AA ratios during design. All interactive elements (buttons, forms, menus) are keyboard-navigable and include ARIA labels where needed. We run automated accessibility audits on every build and address any failures before deployment.
We also include a Lighthouse Accessibility audit score target of 95+ for every site we build. Our portfolio sites consistently score 98–100.
What You Should Do Now
If your current site was not built with accessibility in mind, run a free audit at wave.webaim.org. The most common (and legally dangerous) issues will surface immediately. If you are building a new site, insist that WCAG 2.1 AA compliance is a delivery requirement — not an optional add-on.
