ADA compliance for e-commerce: the violations that generate lawsuits
Most accessibility claims cite the same six machine-detectable failures. All six are findable in minutes.
E-commerce is the most-sued sector in US web accessibility litigation, and it is not close. The reason is structural: stores have product grids, filters, image-heavy pages, modals and multi-step checkouts — exactly the components that break for screen reader and keyboard users. The encouraging part is that most demand letters cite the same short list of failures, and automated testing finds nearly all of them.
The six failures behind most claims
| Failure | WCAG | Where it shows up in a store |
|---|---|---|
| Images without alternative text | 1.1.1 | Product photos, banner images, payment icons |
| Insufficient colour contrast | 1.4.3 | Sale prices, placeholder text, disabled buttons, footers |
| Form inputs without labels | 3.3.2 | Search, newsletter, quantity, checkout address fields |
| Controls without accessible names | 4.1.2 | Icon-only cart, wishlist, filter and close buttons |
| Keyboard traps | 2.1.2 | Quick-view modals, promo popups, cookie banners |
| Missing or wrong page structure | 1.3.1 | Headings used for styling, no landmark regions |
The standard to aim for
The ADA does not name a technical standard, but courts, settlements and the DOJ consistently treat WCAG 2.1 AA as the benchmark; 2.2 AA is the current version and adds requirements around focus visibility and drag alternatives. In Europe, the European Accessibility Act has applied to e-commerce since June 2025 and points at the same standard.
How to test your own store
- 1Run an automated scan on your homepage, a collection page, a product page and every checkout step. Automated tools catch roughly a third of issues but nearly all of the ones cited in demand letters.
- 2Unplug your mouse. Tab through a full purchase. If you cannot complete it, neither can a keyboard user.
- 3Open every modal and try to escape it with the keyboard alone.
- 4Zoom to 200% and check nothing is cut off or overlapping.
- 5Turn on your operating system's screen reader and listen to a product page. Unlabelled buttons become obvious immediately.
What not to do
Accessibility overlay widgets — the floating accessibility icon — have not prevented litigation and have themselves been the subject of complaints and an FTC action. They also frequently interfere with the assistive technology a user already has configured. Fix the underlying markup instead.
Keep it from regressing
Accessibility regressions ride in with theme updates, new apps and new product pages. Whatever you fix today, re-test on a schedule and after every deployment. Automated checks across your key templates take minutes and catch the categories that actually get litigated.

Does the ADA apply to online stores?
US courts have widely held that websites of businesses serving the public fall under Title III, particularly where there is a connection to goods and services sold. E-commerce sites are routinely treated as covered.
What standard should I follow for ADA compliance?
WCAG 2.1 AA at minimum, ideally 2.2 AA. It is the standard referenced in DOJ guidance, the vast majority of settlements, and the European Accessibility Act.
Do accessibility overlays make my store compliant?
No. Overlays have not stopped lawsuits, have drawn regulatory attention themselves, and often conflict with users' own assistive technology. Remediating the underlying HTML is the only durable approach.
