Accessibility Is About Customers, Not Just Compliance
Start with the part that gets lost in every legal-risk conversation: an inaccessible website is a website some real customers can't use. Someone using a screen reader can't research your services if your headings are unstructured. Someone navigating by keyboard alone can't book an appointment if your form only responds to a mouse click. Someone with low vision can't read your pricing if the contrast is too low to see it.
The CDC's most recent data puts this in scale: 28.7% of U.S. adults — an estimated 70 million people — report having a functional disability affecting hearing, vision, mobility, cognition, self-care, or independent living. That's not an edge case. It's roughly a quarter of everyone who might land on your homepage. And the fixes that help them — clear structure, real labels, working keyboard navigation — tend to make the site better for every visitor, disabled or not.
How the ADA Relates to Websites
The Department of Justice's own guidance states plainly that the ADA's requirements apply to "all the goods, services, privileges, or activities offered by public accommodations, including those offered on the web." In plain terms: DOJ's position is that a business open to the public generally can't treat its website as exempt from the same obligations that apply to its physical location.
What the DOJ does not do is hand businesses one universal checklist. Its own guidance points to the Web Content Accessibility Guidelines (WCAG) and Section 508 Standards as "helpful guidance," not a single mandated legal standard — and how obligations actually play out depends on your business type, your jurisdiction, and the specific facts of your situation. That variation is real and it matters: the 2025 federal lawsuit data shows California saw just 4 website accessibility filings all year, a direct result of appellate court decisions limiting ADA coverage for online-only businesses in that circuit — while New York alone saw 1,021. Two businesses with an identical website can face very different legal exposure depending on where their customers are and what court would hear the case. That's exactly the kind of question that needs an attorney familiar with your situation, not a blog post.
Common Accessibility Barriers
Most inaccessible sites share the same handful of problems, and none of them require a redesign to understand:
- Poor color contrast that makes text hard to read.
- Missing alt text on meaningful images.
- Video without captions.
- Navigation that only works with a mouse.
- Form fields with no clear label.
- Missing visual focus indicators for keyboard users.
- Error messages that don't explain what actually went wrong.
- Heading structure that skips levels or doesn't reflect the page's actual organization.
What WCAG Means
WCAG organizes accessibility around four principles: content must be perceivable (people can actually sense it, through sight, sound, or touch), operable (people can interact with it, regardless of input method), understandable (the content and interface make sense), and robust (it works reliably across different browsers and assistive technologies).
Within that framework, WCAG defines three conformance levels — A, AA, and AAA, with AA the level most commonly referenced as a reasonable target in practice and in litigation. It's worth being precise here: WCAG is an important technical framework for building accessible sites, but meeting a WCAG level is not the same thing as a guaranteed legal outcome for every private business — the law and the technical standard are related, not identical.
Why Automated Scans Are Not Enough
This is the DOJ's own position, not just an accessibility vendor's talking point. Its guidance states directly: "A 'clean' report does not necessarily mean everything is accessible," and recommends "pairing a manual check of a website with the use of automated checkers" for a realistic picture.
Automated scanners are genuinely useful for catching certain technical issues — missing alt attributes, contrast ratios, some HTML structure problems. What they can't do is tell you whether a screen reader user can actually complete your checkout flow, or whether your error messages make sense read aloud, or whether your keyboard navigation gets trapped somewhere it shouldn't. That requires real testing by a human.
Accessibility overlay widgets deserve a direct word here, because they're marketed as a fast fix and the evidence doesn't support that claim. A WebAIM practitioner survey found 67% rate these tools as not at all or not very effective — a number that climbs to 72% among respondents who are themselves disabled, with only 2.4% rating them very effective. The overlay fact sheet compiled by accessibility practitioners documents specific failures: overlays generally can't fix form labels, error handling, keyboard traps, JavaScript-driven content, or PDFs. The FTC took this seriously enough to act on it — in 2025, it ordered an online marketer to pay $1 million over deceptive claims that its AI-powered tool could make websites accessibility-compliant. That's exactly why we won't tell you a plugin can promise compliance, and why any vendor who does should raise a flag.
A Practical Accessibility Review
A real review combines several methods, not one:
- Automated scan, to catch the technical low-hanging fruit.
- Manual keyboard navigation testing — can you reach and use everything without a mouse?
- Screen-reader testing with real assistive technology.
- Form validation — labels, error states, required-field indication.
- Color and zoom testing at various contrast and magnification levels.
- Content and document review, including PDFs and downloadable files.
- A prioritized remediation plan, ranked by impact, not just alphabetically.
What to Fix First
Not every issue carries equal weight. Prioritize by what actually blocks someone from doing business with you:
- Critical purchasing and conversion paths.
- Primary site navigation.
- Forms — contact, quote requests, applications.
- Authentication and account login.
- Checkout or booking flows.
- Important downloadable documents, like pricing sheets or contracts.
A decorative image with missing alt text is a real issue. A checkout button a keyboard user can't reach is the one costing you customers and creating the most legal exposure today.
Maintaining Accessibility
Accessibility isn't a project with an end date — it's a standard that has to survive every future change to the site:
- Build accessibility requirements into your design and development process, not a review that happens after launch.
- Train the people actually adding content — a marketer uploading an image without alt text undoes a developer's careful work.
- Test before every release, not just once a year.
- Give visitors a real way to report a problem they hit.
- Schedule periodic reviews, since sites drift out of compliance as they grow.
The Business Case
Beyond risk reduction, there's a straightforward business argument here: a broader audience can actually use your site, usability tends to improve for everyone in the process, the same rigor that catches accessibility issues tends to catch other quality problems, and customers notice when a site is easy to use regardless of why it is.
Accessibility Is an Ongoing Practice
The businesses that get burned by this aren't usually the ones with no accessibility plan — they're the ones who bought a widget, considered it solved, and stopped thinking about it. A single scan or plugin isn't an endpoint. It's one input into a practice that has to keep pace with every new page, form, and feature you ship.
If you don't currently know where your site stands, that's the honest starting point — not a guess, an actual review combining automated and manual testing against your specific site and business.
