Common ADA Compliance Mistakes That Put Websites at Risk

As digital experiences become central to how organizations serve customers, employees, students, and citizens, website accessibility has evolved from a best practice into a business necessity. Organizations across industries including healthcare, banking, education, retail, technology, and government are under increasing pressure to ensure their websites are accessible to people with disabilities.

Yet many businesses still misunderstand what is ADA compliance, assuming that installing an accessibility widget or passing an automated scan is enough. In reality, ADA compliance requires an ongoing commitment to accessibility, guided by recognized standards such as the Web Content Accessibility Guidelines (WCAG).

Failing to address accessibility issues can expose organizations to legal complaints, procurement challenges, reputational damage, and poor user experiences.

This guide explains what is ADA compliance, common website accessibility mistakes, and practical steps organizations can take to reduce risk while building inclusive digital experiences.

What Is ADA Compliance?

One of the most common questions organizations ask is, what is ADA compliance?

The Americans with Disabilities Act (ADA) is a U.S. civil rights law that prohibits discrimination against individuals with disabilities. Although the ADA was enacted before the internet became a primary business channel, courts and regulators increasingly interpret it to apply to many websites, digital services, and mobile applications.

When discussing what is ADA compliance website, it refers to ensuring that digital experiences are accessible to users with disabilities. This includes making websites usable for individuals who rely on:

• Screen readers

• Keyboard navigation

• Voice recognition software

• Screen magnifiers

• Alternative input devices

Because the ADA does not prescribe detailed technical website requirements, organizations commonly use WCAG 2.1 or WCAG 2.2 Level AA as the accepted benchmark for accessibility.

What Is ADA Website Compliance?

Understanding what is ADA website compliance goes beyond avoiding lawsuits.

It means creating digital experiences that everyone can access, regardless of physical, sensory, or cognitive abilities.

An ADA-compliant website should enable users to:

• Navigate without a mouse

• Read content using assistive technologies

• Complete online forms independently

• Access documents and downloadable resources

• Watch videos with captions

• Understand page content regardless of disability

Accessibility benefits every visitor by improving usability, navigation, readability, and overall user experience.

Why ADA Compliance Matters

Organizations that prioritize accessibility gain benefits beyond regulatory readiness.

These include:

• Reduced legal exposure

• Better customer experience

• Stronger brand reputation

• Improved search engine optimization (SEO)

• Increased audience reach

• Greater usability across devices

• Better procurement readiness for government and enterprise contracts

Accessibility is not simply a legal obligation—it's part of delivering high-quality digital experiences.

Common ADA Compliance Mistakes That Put Websites at Risk

Many accessibility issues stem from overlooked design and development practices rather than intentional exclusion. Below are some of the most common mistakes that increase accessibility and compliance risks.

1. Relying Only on Automated Accessibility Tools

Automated accessibility scanners can identify common issues, such as missing image alt text or low color contrast. However, they cannot evaluate every aspect of accessibility.

For example, automated tools cannot reliably determine:

• Whether alternative text is meaningful

• If keyboard navigation follows a logical order

• Whether form instructions are clear

• How a screen reader interprets content

• Whether interactive elements behave as expected

Organizations that rely solely on automation often overlook critical usability barriers.

Best Practice: Combine automated testing with expert manual accessibility audits to ensure comprehensive evaluation.

2. Missing or Poor Alternative Text

Images that convey information require descriptive alternative text.

Common mistakes include:

• Missing alt text

• Generic descriptions like "image"

• File names used as alt text

• Overly detailed or inaccurate descriptions

Meaningful alternative text enables screen reader users to understand visual content.

3. Poor Keyboard Accessibility

Many users cannot operate a mouse and instead rely entirely on keyboard navigation.

Common keyboard accessibility issues include:

• Interactive elements that cannot receive keyboard focus

• Menus that require a mouse

• Modal windows users cannot exit

• Hidden focus indicators

If users cannot navigate your website using only a keyboard, important functionality becomes inaccessible.

4. Inadequate Color Contrast

Low-contrast text remains one of the most common accessibility failures.

Poor contrast affects users with:

• Low vision

• Color blindness

• Age-related vision changes

• Mobile device glare

Ensuring sufficient contrast improves readability for everyone.

5. Incorrect Heading Structure

Headings help users understand page organization.

Common mistakes include:

• Skipping heading levels

• Using headings for visual styling only

• Multiple H1 tags without logical structure

• Missing headings entirely

Proper semantic structure improves navigation for screen reader users and supports SEO.

6. Inaccessible Forms

Forms often represent critical business functions, including:

• Contact requests

• Account registration

• Online payments

• Appointment scheduling

Accessibility problems include:

• Missing labels

• Placeholder text used instead of labels

• Unclear validation messages

• Missing error identification

• Inaccessible CAPTCHA implementations

Forms should guide users clearly through every step.

7. PDFs That Are Not Accessible

Organizations frequently publish:

• Reports

• Policies

• Brochures

• Tax documents

• Application forms

Many PDFs remain inaccessible because they lack:

• Proper document tags

• Reading order

• Alternative text

• Searchable text

• Logical headings

Document accessibility should be included within every accessibility strategy.

8. Videos Without Captions or Transcripts

Multimedia content should be accessible to users who are deaf or hard of hearing.

Common issues include:

• Missing captions

• Auto-generated captions without review

• Missing transcripts

• Audio-only information without visual alternatives

Accessible multimedia improves both usability and engagement.

9. Improper Use of ARIA

Accessible Rich Internet Applications (ARIA) can improve accessibility when used correctly.

However, unnecessary or incorrect ARIA implementation often creates additional barriers.

Examples include:

• Incorrect ARIA roles

• Missing labels

• Duplicate attributes

• Conflicting semantic information

Native HTML elements should be used whenever possible before adding ARIA.

10. Treating Accessibility as a One-Time Project

Accessibility is not something organizations complete once and forget.

Digital products evolve constantly through:

• Website redesigns

• Content updates

• Software releases

• Third-party integrations

• New documents

Without continuous monitoring, accessibility issues inevitably return.

Long-term compliance requires accessibility governance, routine testing, and ongoing remediation.

Why Manual Accessibility Testing Matters

One of the biggest misconceptions surrounding ADA compliance is that automated scans can determine whether a website is compliant.

They cannot.

Expert manual testing evaluates real-world accessibility by assessing:

• Keyboard usability

• Screen reader compatibility

• Reading order

• Form behavior

• Dynamic content

• Focus management

• User workflows

This level of evaluation provides insights that automation alone cannot achieve.

Best Practices for Maintaining ADA Website Compliance

Organizations can strengthen accessibility by embedding it into their digital processes rather than treating it as a reactive task.

Conduct Regular Accessibility Audits

Evaluate websites, applications, and documents using both automated tools and manual expert testing.

Integrate Accessibility Into Development

Include accessibility reviews during design, development, QA testing, and content publishing.

Remediate Accessibility Issues Promptly

Prioritize issues that prevent users from accessing critical content or completing essential tasks.

Train Internal Teams

Developers, designers, content creators, and QA professionals should understand accessibility best practices before new content is published.

Establish Accessibility Governance

Create policies, testing schedules, documentation standards, and accountability across departments to ensure long-term compliance.

Choosing an Accessibility Partner

Maintaining ADA compliance requires technical expertise and ongoing support.

When evaluating an accessibility partner, look for providers that offer:

• Expert-led manual audits

• WCAG evaluations

• ADA and Section 508 expertise

• PDF remediation

• Mobile accessibility testing

• Accessibility verification

• VPAT/Accessibility Conformance Report (ACR) support

• Continuous accessibility monitoring

• Developer remediation guidance

• Accessibility governance consulting

An experienced partner helps organizations move beyond one-time fixes toward sustainable accessibility programs.
