How to Audit Your Website Against ADA Compliance Guidelines

Website accessibility is no longer something organizations can afford to treat as an afterthought. For businesses, government agencies, healthcare providers, financial institutions, educational organizations, and other enterprises, digital accessibility is closely connected to equal access, compliance, procurement, and risk management.

But how do you know whether your website is accessible?

A website audit provides a practical starting point. By reviewing your website against recognized accessibility requirements, you can identify barriers that may prevent people with disabilities from navigating pages, completing forms, understanding content, or using interactive features.

It is important to understand that the Americans with Disabilities Act (ADA) does not provide a single technical checklist specifically called the “ADA website guidelines.” In practice, organizations commonly use the Web Content Accessibility Guidelines (WCAG) as the technical benchmark for evaluating digital accessibility. The appropriate requirements can also depend on the organization, industry, and applicable laws or regulations.

This guide explains how to audit a website against ADA website accessibility guidelines, where ADA web accessibility guidelines fit into the process, and why automated testing alone is not enough.

What Are ADA Website Accessibility Guidelines?

The term ADA website accessibility guidelines is commonly used to describe the accessibility practices organizations follow to make websites usable by people with disabilities.

The ADA is a U.S. civil rights law that prohibits discrimination against people with disabilities. While the ADA itself does not function as a detailed web-development standard, WCAG provides widely used technical criteria for evaluating digital accessibility.

WCAG addresses four fundamental principles:

• Perceivable: Users must be able to perceive the information being presented.

• Operable: Users must be able to operate interface components and navigate the website.

• Understandable: Information and functionality should be understandable.

• Robust: Content should work reliably with different user agents and assistive technologies.

These principles provide the foundation for a structured website accessibility audit.

Why Should You Audit Your Website for ADA Accessibility?

An accessibility audit helps organizations understand their current digital accessibility position.

A properly conducted audit can help you:

Identify Accessibility Barriers

Discover problems that may prevent users with disabilities from accessing content or completing important tasks.

Reduce Compliance Risk

Finding accessibility issues early allows organizations to address them before they contribute to complaints, legal disputes, or procurement concerns.

Improve User Experience

Many accessibility improvements also make websites easier for everyone to navigate and understand.

Support Procurement Requirements

Organizations working with government agencies or enterprise customers may need documentation of their accessibility practices.

Establish a Remediation Plan

A detailed audit provides development teams with information they can use to prioritize and resolve accessibility issues.

How to Audit Your Website Against ADA Compliance Guidelines

A comprehensive website audit should combine automated testing, manual evaluation, and assistive technology testing.

1. Define the Audit Scope

Before testing begins, determine what needs to be evaluated.

For a large website, auditing every page individually may not be practical. Instead, identify representative page templates, important user journeys, and high-value functionality.

Your scope may include:

• Homepage

• Navigation

• Product or service pages

• Search functionality

• Login and registration

• Contact forms

• Checkout

• Account management

• Multimedia

• PDFs and downloadable documents

• Interactive components

• Mobile experiences

Critical workflows deserve particular attention because an accessibility barrier in a checkout, application, or registration process can prevent a user from completing an essential task.

2. Test Keyboard Accessibility

Not every visitor uses a mouse.

People with motor disabilities and users of certain assistive technologies may rely entirely on keyboard commands to navigate websites.

Check whether users can:

• Move through interactive elements logically

• Access every link and button

• Open and close menus

• Complete forms

• Operate dialogs

• Navigate interactive components

• See where keyboard focus is located

A visible and logical focus indicator is particularly important.

If a user becomes trapped inside a component or cannot reach an essential function using the keyboard, the experience may present a significant accessibility barrier.

3. Check Heading Structure and Page Organization

Headings provide a structural outline of a webpage.

Review whether:

• Each page has an appropriate main heading

• Heading levels follow a logical structure

• Headings describe the content that follows

• Sections are organized consistently

Proper structure benefits screen reader users and makes lengthy pages easier for everyone to scan.

Avoid selecting headings simply because a particular heading style looks visually attractive. Heading elements should represent the actual structure of the content.

4. Evaluate Images and Alternative Text

Images that communicate information should generally have meaningful alternative text.

During an audit, review whether:

• Informative images have appropriate alt text

• Decorative images are appropriately treated as decorative

• Functional images communicate their purpose

• Complex graphics have an appropriate text alternative

For example, an image used as a button should communicate the action it performs rather than simply describing its appearance.

Poor alternative text can make otherwise useful content confusing for screen reader users.

5. Check Color Contrast

Text and important visual information should have sufficient contrast against their backgrounds.

Review:

• Body text

• Headings

• Buttons

• Form controls

• Links

• Placeholder text

• Important graphical information

Do not rely on color alone to communicate meaning.

For example, telling users that “required fields are shown in red” may create a barrier for people who cannot distinguish the colors.

6. Test Forms and Error Messages

Forms are among the most important areas to evaluate because accessibility problems can prevent users from completing essential tasks.

Check whether forms have:

• Properly associated labels

• Clear instructions

• Logical field order

• Accessible error identification

• Helpful error messages

• Appropriate focus behavior

• Clearly identified required fields

Test the entire workflow rather than reviewing individual fields in isolation.

A form may have correctly labeled inputs but still create accessibility problems if errors are difficult to understand or users cannot determine how to correct them.

7. Evaluate Links and Buttons

Links and buttons should communicate their purpose clearly.

Avoid vague labels such as:

• Click here

• Read more

• Learn more

when the destination or action is unclear from context.

Also verify that interactive elements:

• Are keyboard accessible

• Have accessible names

• Have visible focus

• Can be activated reliably

• Provide appropriate state information when necessary

Clear controls make navigation easier for users and assistive technologies.

8. Test Dynamic and Interactive Content

Modern websites rely heavily on JavaScript and dynamic interfaces.

Menus, pop-ups, accordions, tabs, carousels, dialogs, and notifications all require accessibility testing.

Check whether:

• Keyboard users can operate the component

• Focus moves appropriately

• Focus is not lost

• Screen readers receive important updates

• Controls communicate their current state

• Users can close or exit components

Automated testing often cannot determine whether these interactions make sense to a real user.

9. Test With Screen Readers

Screen reader testing is an important component of a comprehensive accessibility evaluation.

Commonly used screen readers include:

• NVDA

• JAWS

• VoiceOver

• TalkBack

Test important workflows from beginning to end.

For example, a user should be able to navigate from a product page to a checkout form and understand the information, controls, instructions, and status messages along the way.

Screen reader testing can reveal issues involving reading order, labels, headings, landmarks, focus management, and dynamic content that automated scanners may miss.

10. Review Multimedia and Documents

Accessibility does not stop with HTML webpages.

Review:

Videos

Check for appropriate captions and, where applicable, audio descriptions.

Audio

Provide transcripts when needed.

PDFs

Evaluate document structure, tagging, reading order, alternative text, forms, and other relevant accessibility features.

Downloadable Documents

Word, PowerPoint, and Excel files should also be reviewed when they form part of the user experience.

A website may be accessible while an essential downloadable document remains inaccessible.

11. Use Automated Accessibility Testing

Automated testing can make accessibility auditing faster and more scalable.

ADA compliance guidelines can be evaluated with automated tools for issues such as:

• Missing alternative text

• Certain color contrast problems

• Missing form labels

• Invalid or problematic markup

• Some ARIA errors

• Empty links and buttons

However, automated testing has important limitations.

A tool may confirm that an image contains alt text, for example, but it cannot reliably determine whether that alt text actually communicates the image's purpose.

That is why automated testing should be treated as one part of a broader accessibility audit.

12. Map Findings to WCAG

Once issues have been identified, map them to the applicable WCAG Success Criteria.

A useful audit report should explain:

• What the issue is

• Where it occurs

• Which users may be affected

• Relevant WCAG Success Criterion

• Why the issue matters

• Recommended remediation

• Severity or priority

This makes the audit more useful for development, accessibility, compliance, and governance teams.

13. Prioritize Accessibility Issues

Not every issue has the same impact.

Prioritize remediation based on factors such as:

• Whether an essential function is blocked

• Number of users potentially affected

• Severity of the accessibility barrier

• Frequency of occurrence

• Business importance of the affected workflow

• Technical complexity of remediation

For example, an inaccessible checkout process may deserve immediate attention because it can prevent users from completing a transaction.

14. Remediate and Retest

An audit identifies problems; remediation addresses them.

After developers implement fixes, conduct validation testing to determine whether:

• The original issue has been resolved

• The fix works across relevant browsers and devices

• Assistive technology users can complete the affected workflow

• The change has introduced new accessibility problems

This verification stage is essential.

Why an ADA Website Audit Should Not Rely on a Compliance Checker

An automated ADA compliance checker can be useful for identifying detectable technical issues, but it should not be treated as proof that a website is fully accessible.

Automated tools generally cannot determine whether:

• Alternative text is meaningful

• Keyboard navigation feels logical

• A form is genuinely understandable

• Focus is managed correctly

• Dynamic content is communicated properly

• A screen reader user can complete a workflow

• Content makes sense in context

A professional audit therefore combines automated analysis with manual testing and assistive technology evaluation.

Common Mistakes During an Accessibility Audit

Organizations can weaken their accessibility programs by:

Relying Only on Automated Scans

Automation is valuable, but it cannot evaluate every accessibility requirement.

Testing Only the Homepage

Important barriers often exist deeper within forms, applications, checkout processes, and other workflows.

Fixing Errors Without Understanding the User Impact

A technical fix should address the underlying accessibility barrier rather than simply remove a scanner warning.

Treating Accessibility as a One-Time Project

Websites change continuously. New content, components, integrations, and releases can introduce new barriers.

Ignoring Documents and Third-Party Content

Accessibility should cover the broader digital experience, not just the main website templates.

Build an Ongoing Accessibility Program

A website audit is the starting point—not the finish line.

Organizations should integrate accessibility into:

• Design

• Development

• Quality assurance

• Content creation

• Procurement

• Product management

• Release processes

• Governance

Regular testing helps identify regressions before they become larger problems.

For enterprise organizations, an accessibility governance framework can also define responsibilities, testing requirements, remediation processes, documentation standards, and escalation procedures.
