ADA website compliance means making your website usable by people with disabilities, as required by the Americans with Disabilities Act. Title III covers businesses open to the public, and the Department of Justice says that includes goods and services offered online. The ADA does not name a technical standard for private businesses, so courts and settlements use the Web Content Accessibility Guidelines (WCAG) Level AA.
Most website owners never think about ADA website compliance until a demand letter arrives. By then, the clock is already running.
So, is your website ADA compliant? Odds are it is not. WebAIM found detectable WCAG failures on 95.9% of the top one million home pages in 2026.1
According to the CDC, more than 1 in 4 U.S. adults live with some type of disability.2 When your site blocks them, you lose the sale, and increasingly you get sued. Plaintiffs filed more than 5,000 digital accessibility lawsuits in 2025, according to UsableNet, and nearly 70% named ecommerce businesses.3
A good-looking site is not the same as an accessible website. Accessibility lives in the markup, the content, and the interactions, which is why it belongs in your web design and development process from the start, not in a plugin added at the end.
What Is ADA Website Compliance?
ADA website compliance means people with disabilities can perceive, navigate, and use your website as fully as everyone else, from reading content to completing a purchase.
The Americans with Disabilities Act became law in 1990 and says nothing about HTML. Department of Justice guidance fills that gap. It states that ADA requirements apply to goods and services a business offers on the web, and it names WCAG as helpful technical guidance.4
There is no official ADA certification for websites. No government agency tests or certifies sites, so treat any "ADA certified" badge with suspicion. What protects you is documented WCAG conformance: an audit report, fixes, and ongoing testing.
Most barriers start as design decisions. Good UI and UX design prevents them before a developer writes a line of code.
Does the ADA Apply to Your Website?
The ADA applies to your website if you are a business open to the public or a state or local government.
| Law | Who it covers | Web standard | Key date |
|---|---|---|---|
| ADA Title II | State and local governments, including public schools | WCAG 2.1 AA, set by DOJ rule | April 26, 2027 (50,000+ population); April 26, 2028 (smaller entities) |
| ADA Title III | Businesses open to the public, such as retailers, restaurants, and banks | No rule; courts and settlements use WCAG AA | In force now |
| European Accessibility Act | Businesses selling ecommerce services to EU consumers | Accessibility requirements set by the Directive | In force since June 28, 2025 |
The landmark case is Robles v. Domino's Pizza. In 2019, the Ninth Circuit ruled that the ADA covers Domino's website and app because they connect customers to its restaurants.5 The Supreme Court declined to review it in October 2019.6 Courts still disagree on whether online-only stores are covered, so relying on that gap is risky.
The DOJ's April 2026 extension of the Title II deadlines covers government bodies only.7 Title III lawsuits against private businesses never depended on a deadline.
If you sell into Europe, the European Accessibility Act has applied to e-commerce services since June 28, 2025.8 A short consulting assessment can map which of these laws touch your markets and platforms.
What Happens If Your Website Is Not ADA Compliant?
If your website is not ADA compliant, you face demand letters, lawsuits, settlement costs, and lost sales. UsableNet's 2025 data shows the scale:
- Volume: more than 3,100 federal lawsuits plus nearly 2,000 in New York and California state courts.3
- Repeat targets: 45% of federal cases named companies that had already faced an ADA web claim.
- Big brands: 35.8% of the top 500 ecommerce retailers received at least one ADA accessibility lawsuit in 2025.
What an ADA Website Lawsuit Costs
Under federal law, private plaintiffs mostly win injunctions and attorney's fees. The DOJ can seek civil penalties up to $118,225 for a first violation and $236,451 after that.9 California's Unruh Civil Rights Act adds damages of no less than $4,000 per offense.10
Fixing the site on your own schedule costs less than rushed remediation. BigCommerce merchants can fold accessibility into a store audit instead of treating it as an emergency.
What Is WCAG Compliance?
WCAG compliance means your website meets the success criteria in the Web Content Accessibility Guidelines, published by the World Wide Web Consortium (W3C).
The Four POUR Principles of WCAG
Perceivable
Perceivable means users can see or hear the content, through alt text, captions, and enough contrast.
Operable
Operable means users can navigate and use every feature with a keyboard alone.
Understandable
Understandable means pages behave predictably and error messages explain how to fix the problem.
Robust
Robust means clean code works with assistive technology like JAWS, NVDA, VoiceOver, and TalkBack.
WCAG Conformance Levels: A, AA, and AAA
Level A is the minimum. Level AA is the level courts, settlements, and the DOJ rule use. Level AAA is rarely required for a whole site.
Which WCAG Level Should Your Website Target?
Target WCAG Level AA, the level in the DOJ's Title II rule and most settlements.
WCAG 2.1 AA vs WCAG 2.2 AA
WCAG 2.2 adds nine success criteria to WCAG 2.1, and content that conforms to 2.2 also conforms to 2.1.11 Building to WCAG 2.2 AA covers both.
What WCAG 2.2 Adds for Ecommerce Sites
- Target Size (Minimum): tap targets large enough to hit on a phone.
- Focus Not Obscured: sticky headers cannot hide the focused element.
- Redundant Entry: no retyping an address already entered.
- Accessible Authentication: login cannot require solving a puzzle.
These WCAG 2.2 criteria mostly affect mobile, so treat responsive web design and accessibility as one job.
What About WCAG 3.0?
WCAG 3.0 is still a W3C draft. The W3C says it will not supersede WCAG 2, and it recommends meeting WCAG 2.2 now as the best preparation.12
How to Check If Your Website Is ADA Compliant
You can check whether your website is ADA compliant with a 15-minute self-test, then confirm it with a professional WCAG audit. Test your home page, a product page, and checkout:
- Use only the Tab key. Every link, button, and field should show a visible focus outline, in logical order.
- Zoom to 200%. Text should stay readable and nothing should overlap or disappear.
- Run a free scanner. Tools like WAVE or axe flag missing alt text, low contrast, and unlabeled fields.
- Turn on a screen reader. Use VoiceOver or NVDA to add a product to the cart and check out.
- Inspect product images. Meaningful images need descriptive alt text, not file names.
If any check fails, your site has accessibility barriers. If all five pass, you still need a full audit, because automated tools miss issues that only manual testing with assistive technology finds.
Scanners confirm alt text exists, not that it is useful. On older codebases, a code audit shows which components will keep producing accessibility bugs.
What Are the Most Common Website Accessibility Errors?
The most common website accessibility errors are low contrast text, missing alt text, and missing form labels. In WebAIM's 2026 study, failing home pages averaged 56.1 errors each.1
| Error | Share of home pages | What it breaks |
|---|---|---|
| Low contrast text | 83.9% | Readability for low-vision users |
| Missing image alt text | 53.1% | Images for screen reader users |
| Missing form input labels | 51.0% | Search and checkout forms |
| Empty links | 46.3% | Icon links that announce nothing |
| Empty buttons | 30.6% | Unnamed cart and menu buttons |
| Missing document language | 13.5% | Correct screen reader pronunciation |
Most need template and content fixes, not a rebuild. Low contrast buttons and unlabeled fields also hurt sales, making them conversion-focused design problems too.
Do Accessibility Overlays Make a Website ADA Compliant?
No. Accessibility overlays, toolbar widgets that promise one-line compliance, do not make a website ADA compliant.
In January 2025, the Federal Trade Commission announced an order requiring accessiBe to pay $1 million over claims that its AI widget could make any website WCAG compliant.13 UsableNet's data shows businesses using widgets faced 95 to 155 new lawsuits every month in 2025.3
Overlays sit on top of broken code and guess. They cannot write meaningful alt text or fix a keyboard trap in checkout.
Real fixes belong in your codebase, backed by QA and test automation that catches regressions before they ship.
What Are the Most Common ADA Issues on Ecommerce Sites?
The most common ADA issues on ecommerce sites sit in product pages, filters, and checkout, where one barrier can block a purchase.
- Product pages: images lack alt text, swatches rely on color alone, and keyboards cannot reach size selectors.
- Search and filters: filter checkboxes lack labels, and results update without telling screen reader users.
- Cart and checkout: fields lack labels, errors show only in red, and payment iframes trap keyboard focus.
- Pop-ups: email capture modals cannot be closed with a keyboard.
On Shopify, many of these issues come from theme and app code. A Shopify UX audit catches them alongside your other experience fixes.
How to Make Your Website ADA Compliant in Six Steps
To make your website ADA compliant, audit it against WCAG 2.2 AA, fix the highest-risk journeys first, retest with assistive technology, and monitor every release.
- Audit against WCAG 2.2 AA. Combine automated scans with manual assistive technology testing.
- Prioritize by risk. Fix checkout, search, and product pages first.
- Remediate in code, content, and design. Fix shared templates and components so every page improves at once.
- Retest with assistive technology. Confirm fixes with real screen readers, not just a scanner score.
- Document your conformance. Publish an accessibility statement. B2B and public-sector buyers may also ask for a VPAT or Accessibility Conformance Report (ACR).
- Monitor and train. Check every release, vet new apps, and re-audit yearly.
Teams building custom web applications should build accessible components into the design system. After launch, post-launch support keeps fixes from slipping, and a multi-site CMS enforces the same accessible components across every brand.
How Does Website Accessibility Affect SEO and AI Search?
An accessible website is usually easier for search engines and AI tools to read, because both depend on the same signals screen readers use: headings, alt text, labels, and descriptive link text. That work overlaps heavily with technical SEO, and it supports AIO and GEO optimization.

Frequently Asked Questions
Is ADA website compliance legally required?
For businesses open to the public, yes in practice. The DOJ says the ADA covers goods and services offered online, even without a federal technical rule for private websites.
Is there an official ADA certification for websites?
No. No government agency certifies websites as ADA compliant. The best evidence of ADA website compliance is a documented WCAG 2.2 AA audit, completed fixes, an accessibility statement, and ongoing testing.
Is WCAG the same as the ADA?
No. The ADA is the law, and WCAG is the technical standard courts, settlements, and the DOJ use to measure whether a website meets it.
What WCAG level does ADA website compliance require?
ADA website compliance generally means WCAG Level AA. Building to WCAG 2.2 AA also satisfies WCAG 2.1 AA, the version in the DOJ's Title II rule and in most settlements.
Did the DOJ delay ADA website compliance deadlines?
Only for state and local governments, whose Title II deadlines moved to April 2027 and April 2028. Nothing changed for private businesses under Title III.
Will an accessibility overlay protect my website from lawsuits?
No. Businesses using overlay widgets were sued every month in 2025, and the FTC ordered one overlay vendor to pay $1 million over its compliance claims.
How much does an ADA website audit cost?
ADA website audit cost depends on scope, not page count. Price drivers are the number of unique templates, custom features like portals, third-party apps, and whether manual assistive technology testing is included. Ask for a fixed quote after a scoping call.
What is the difference between the ADA, Section 508, and a VPAT?
The ADA is a civil rights law covering businesses and governments. Section 508 sets accessibility standards for federal agency technology. A VPAT is a vendor template that becomes an Accessibility Conformance Report once completed.
Does a Shopify store need to be ADA compliant?
Yes. A Shopify store needs to be ADA compliant like any other online store. Shopify hosts the platform, but you own the theme, apps, and content, so accessible Shopify store design starts with a tested theme and careful app choices.
Can I get sued while I am fixing my website?
Yes. Remediation in progress does not stop a lawsuit, but a documented audit and dated fix plan put you in a much stronger position.
The Bottom Line
An untested website almost certainly has barriers. Find them before a law firm does.
ADA website compliance is not a badge or a widget. It is a practice: build to WCAG 2.2 AA, test with assistive technology, and recheck every release.
Start with product pages and checkout, then build accessible patterns into your ecommerce web design so every new page ships compliant by default.
