Why Accessibility Overlays Don't Work — And What to Do Instead

AccessiBe was fined $1 million by the FTC. Over 800 accessibility professionals signed a letter opposing overlays. Here's why they fail and what actually works.

The Promise vs. the Reality

Accessibility overlay companies like AccessiBe, UserWay, and EqualWeb promise WCAG compliance with a single line of JavaScript. The pitch is appealing: add one script tag to your site and instantly become accessible. No code changes, no developer time, no ongoing maintenance.

The reality is very different.

The Evidence Against Overlays

The FTC Takes Action

In January 2025, the Federal Trade Commission fined AccessiBe $1 million for deceptive claims that its AI-powered product could make websites compliant with WCAG standards. The FTC found that AccessiBe's marketing claims were misleading — the product simply could not deliver what it promised.

The final order was approved in April 2025, making it clear that the federal government views overlay compliance claims as deceptive marketing.

800+ Professionals Say No

The Overlay Fact Sheet, signed by over 800 accessibility professionals, documents the technical failures of overlay products. These are the people who build accessible websites, conduct audits, and develop assistive technologies — and they are unanimous in opposing overlays.

Named in 400+ Lawsuits

Websites using accessibility overlay tools have been named in over 400 lawsuits. Having an overlay installed has not protected a single business from litigation. In several cases, plaintiffs have specifically cited the overlay as evidence that the business was aware of accessibility problems but chose a cosmetic fix over real remediation.

The National Federation of the Blind

The NFB, the largest advocacy organization for blind Americans, called AccessiBe "misleading and harmful" — a direct statement from the community these tools claim to serve.

Why Overlays Fail Technically

They Can't Fix What They Can't See

Overlays operate at the presentation layer — they add JavaScript on top of existing HTML. But most WCAG violations exist in the HTML structure itself:

• Missing alt text — An AI cannot reliably describe what an image means in context. A photo of a person could be "our CEO," "a satisfied customer," or "stock photo placeholder" depending on context the AI doesn't have.
• Broken heading hierarchy — Overlays can't restructure your HTML document. If your H1 jumps to H4, the DOM structure is wrong regardless of what JavaScript does on top.
• Keyboard traps — If a third-party booking widget traps keyboard focus, an overlay script running on your page can't reach inside that widget's iframe.
• Missing form labels — Overlays can guess which label goes with which field, but they frequently guess wrong, creating confusion for screen reader users.

They Can Make Things Worse

Overlay scripts can interfere with screen readers that already handle many tasks natively. When an overlay modifies ARIA attributes or injects its own focus management, it can break functionality that was already working. Several studies have documented cases where accessibility scores decreased after overlay installation.

What Actually Works

Real WCAG compliance requires fixing the source code. There's no shortcut, but the work is well-defined:

1. Audit — Identify every WCAG violation through automated scanning and manual testing
2. Fix the HTML — Add proper alt text, correct heading structure, label form fields, implement skip navigation, fix color contrast at the CSS level
3. Test with real assistive technology — Verify with NVDA, JAWS, or VoiceOver that the fixes actually work for real users
4. Monitor ongoing — Scan regularly to catch regressions when content is updated

This is exactly the process I follow for every client. It takes longer than pasting a script tag, but it actually makes your site accessible — which is the entire point.

The Bottom Line

If your web developer or a sales pitch suggests an overlay tool for WCAG compliance, that's a red flag. The FTC has called it deceptive. The accessibility community has rejected it. And courts are not accepting it as a defense.

Spend the money on real fixes. Your customers with disabilities will thank you, and your legal exposure will actually decrease — not just feel like it decreased.
