Website accessibility for small businesses: what matters and what overlays don't fix

Accessibility means people with disabilities can use your website: someone who can't use a mouse, someone using a screen reader, someone who needs to zoom to 200%. It's also good business. The same fixes make forms easier for everyone, and a customer who can't finish checkout doesn't buy.

For small businesses there's a second reason to care. In the US, most website accessibility lawsuits target companies with under $25 million in revenue, with e-commerce the most common target (UsableNet). In the EU, the European Accessibility Act has applied to many online shops and services since June 2025, with an exemption for microenterprises.

This guide is not legal advice. It's what a developer checks and fixes.

Skip the overlay widget

Overlay widgets promise one line of code and instant compliance. They don't change the site's underlying code, so the real barriers stay. Sites using them are still sued, and in 2025 the US Federal Trade Commission ordered one overlay vendor to pay $1 million over claims that its product made any website compliant.

Fixing the code costs more upfront, and it's the only thing that actually works.

The standard: WCAG 2.2 AA

The target is WCAG 2.2 level AA, the current Web Content Accessibility Guidelines. You don't need to read it all. Most real problems on small business sites fall into a short list.

The problems that show up most

1. Low contrast text. Light gray text on white is the most common failure. Body text needs a contrast ratio of at least 4.5:1.
2. Form fields without labels. A placeholder that disappears when you type is not a label. Screen readers need a real <label> for each field.
3. Errors nobody can find. "There was a problem" at the top of a long form, with no field marked and nothing announced to a screen reader.
4. Things you can't reach by keyboard. Menus, date pickers, pop-ups and custom buttons that only work with a mouse. Tab through your own site: can you reach and use everything, and can you see where the focus is?
5. Images without alt text. Product photos and image buttons need a short text description; decorative images need an empty one.
6. Pop-ups that trap you. A cookie banner or chat window you can't close by keyboard, or that steals focus.
7. Links that say "click here". Link text should say where it goes.
8. Broken zoom and phone layouts. Content that overlaps or disappears at 200% zoom or on a narrow screen.

Test your own site in 15 minutes

• Keyboard: put the mouse away. Use Tab, Shift+Tab, Enter and Space to sign up, book or buy.
• Zoom: zoom the browser to 200%. Can you still read and use everything?
• Automated check: run a free checker such as the axe DevTools browser extension or Lighthouse on your key pages. Fix what it finds, but remember it only catches part of the problems.
• Screen reader: turn on VoiceOver (Mac, iPhone) or NVDA (Windows, free) and try your main form.

Where to start

Don't try to fix the whole site at once. Pick the flows that make you money: home page, product or service page, sign-up, checkout or booking, contact. Fix those first, then make sure new pages don't bring the problems back, for example with an automated check in your deployment.

Add an accessibility statement that honestly says what you've tested, what's still being fixed, and how people can reach you if something doesn't work.
