Quick Answer
Web accessibility means your website works for everyone — including the 1 in 6 people with a disability who may rely on a screen reader, keyboard navigation, or magnified text. The standard is WCAG, now at version 2.2, and the enforcement level for most businesses is AA.
This is no longer optional. In the US, the ADA has been applied to websites, and roughly 40,000+ digital accessibility demand letters are sent each year. The EU's European Accessibility Act now requires WCAG 2.1 AA for most public-facing sites. Accessibility is a legal risk, an SEO lever, and a conversion win — and fixing it properly is far cheaper than most owners expect.
What WCAG Actually Means (Without the Jargon)
WCAG organizes accessibility into four principles:
| Principle | Meaning | Examples of fixes |
|---|---|---|
| Perceivable | Users can perceive the content | Alt text on images, captions on video, enough color contrast |
| Operable | Users can navigate and use it | Full keyboard support, visible focus states, no mouse-only traps |
| Understandable | Content and behavior make sense | Clear labels, predictable navigation, readable language |
| Robust | Works with assistive technology | Valid HTML, proper heading structure, good ARIA usage |
Each principle has three levels:
- ▪A — essential basics (skip links, alt text, keyboard access).
- ▪AA — the legal target: adequate contrast, captions, consistent navigation.
- ▪AAA — the gold standard, rarely required and sometimes impractical.
For 99% of businesses, WCAG 2.2 AA is the target. That's what ADA lawsuits, the EAA, and most procurement requirements reference.
The Legal Risk Is Real
- ▪In the US, federal court ADA website lawsuits run into the thousands each year, and settlement demand letters are estimated in the tens of thousands — many sent to small businesses who never expected a target.
- ▪The European Accessibility Act applies to most public-facing sites and services, enforced since 2025, with real fines in several member states.
- ▪Canada's AODA and state-level rules add more layers.
The pattern is consistent: a site is checked, dozens of WCAG failures are documented, and a demand letter offers a "settlement" — often in the five figures. Retrofitting accessibility after the letter is far more expensive than doing it right the first time.
The Business Case (Beyond Compliance)
Accessibility isn't a tax — it's an investment that pays back three ways:
- ▪It's good SEO. Most WCAG fixes overlap with ranking factors: heading structure, descriptive link text, image alt text, semantic HTML, and fast-loading, responsive layouts. An accessible site is a search-friendly site. (See how these overlap with technical SEO.)
- ▪It lifts conversions. One in six people has a disability, and most also have household buying power. Captions help in loud environments; keyboard support helps power users; high contrast helps older customers. Accessibility features are used by everyone, not just the people they're designed for.
- ▪It protects the brand. An accessibility complaint that goes public is a reputational hit that costs more than any remediation.
The Five Failures That Account for Most SMB Accessibility Issues
From the accessibility audits we run, these five issues show up on almost every site:
- ▪Missing alt text — images that a screen reader can't describe.
- ▪Unlabeled form fields — contact and booking forms that assistive tech can't fill out. Irony: for a local business, the form is often the whole point.
- ▪Low color contrast — light gray text on white that fails the 4.5:1 ratio.
- ▪No keyboard navigation — dropdown menus and modals that can't be reached with Tab/Enter.
- ▪Mouse-only interactions — hover-only menus, drag-only carousels, tiny tap targets.
Fix those five and you clear the majority of a standard WCAG audit.
Accessibility Overlays: The Trap
You'll see ads for "$49/mo accessibility widget — instant compliance." Don't fall for it.
Overlays do not fix your code. They inject a layer that can break screen readers and keyboard users, they give a false sense of compliance, and advocacy groups actively campaign against them. Sites using overlays have been named in lawsuits right alongside sites with no accessibility work at all. The courts want real, documented remediation — not a widget.
What Accessibility Actually Costs
| Approach | Cost | Verdict |
|---|---|---|
| Built into a new build | +5–10% of design/dev time | Cheapest and best — do this |
| Fix-only on an existing site | $1,000–$5,000 (site-size dependent) | Reasonable for one-time remediation |
| Automated scan + manual fixes | $500–$2,000 | Great starting point |
| Overlay widget | $50–$200/mo forever | Avoid — doesn't fix the code |
Building accessibility into a new site is nearly free — it's a skill, not an add-on. The expensive version is remediation after a demand letter.
Next Steps
If you run a business site, spend 20 minutes today: tab through your own site (no mouse), check contrast with a free checker, and look at the image alt text. That's a free mini-audit. For the real thing — an automated scan plus a manual WCAG 2.2 AA review with a prioritized fix list — book a free accessibility consultation. If you're planning a build, make sure accessibility is in the scope from day one: estimate your project cost and see what a compliant build costs.
