Website Accessibility for Small Businesses: What You Need to Know

Website accessibility means building a site that people with disabilities can use: people who are blind and use screen readers, people with low vision who zoom or need strong contrast, people who navigate by keyboard rather than mouse, people with hearing loss who rely on captions, and people with cognitive or motor impairments who need clear layouts and forgiving forms.

For small businesses, it often arrives as a vague worry: is there a law, does it apply to us, will we get a letter? The more useful way to approach it is practical. Accessibility problems turn customers away, some legal frameworks do apply to many businesses, and the most important fixes are usually achievable without rebuilding the site.

This article is general information rather than legal advice. If you have specific legal exposure, speak to a qualified adviser in your jurisdiction.

The standard everyone refers to: WCAG

The Web Content Accessibility Guidelines, published by the W3C, are the reference point used by most laws and policies. The current version is WCAG 2.2, published in October 2023. The guidelines are organised into levels A, AA and AAA, and level AA is the target that most regulations and procurement requirements point to.

WCAG is organised around four principles: content must be perceivable, operable, understandable, and built to work reliably with assistive technologies. In practice that translates into concrete checks, such as text alternatives for images, sufficient colour contrast, keyboard access to everything, visible focus indicators, captions for video, clear labels on forms and meaningful heading structure.

Which rules might apply to you

The legal picture differs by country and by the kind of business.

European Union. The European Accessibility Act has applied since 28 June 2025 to a defined set of products and services, including e-commerce. It applies to businesses selling those services to consumers in the EU, including some based outside it. Microenterprises providing services, broadly those with fewer than ten employees and annual turnover or balance sheet total not exceeding two million euros, are exempt from the service requirements. Implementation is through each member state’s national law, so details vary.

United Kingdom. The Equality Act 2010 requires service providers to make reasonable adjustments so disabled people are not put at a substantial disadvantage, which is widely understood to include websites. Public sector bodies have separate, more specific accessibility regulations.

United States. The Americans with Disabilities Act has been the basis for a large number of lawsuits and demand letters about inaccessible websites of private businesses, particularly in retail and hospitality, even though the law does not set out a specific technical standard for them. Federal rules adopted in 2024 set WCAG 2.1 AA as the standard for state and local government websites.

If you sell online to consumers, operate in a regulated sector or work with public bodies, accessibility deserves serious attention now. For other small businesses it is still worthwhile, for the commercial reasons below.

Why it matters beyond compliance

A significant share of the population lives with some form of disability, and many more have temporary or situational limitations: a broken wrist, bright sunlight on a phone screen, an older relative using your site. Accessibility improvements tend to help everyone. Clear headings, readable contrast, descriptive links, forms with proper labels and captions on video make sites easier to use generally.

There is also overlap with search and mobile usability. Text alternatives, logical heading structure and descriptive link text help search engines understand pages. Larger tap targets and readable text are core to mobile usability, which we cover in why websites fail on mobile.

The fixes that matter most

A full WCAG audit covers a lot of criteria, but a handful of issues account for many of the barriers found on typical small business sites.

• Colour contrast. Light grey text on white, or text over busy images, is hard for many people to read. Check contrast against WCAG AA ratios.
• Images without alternative text. Meaningful images need concise alt text describing their purpose. Decorative images should have empty alt text so screen readers skip them.
• Forms without labels. Placeholder text that disappears is not a label. Each field needs a visible, programmatically associated label and clear error messages.
• Keyboard traps and invisible focus. Everyone should be able to reach and use menus, buttons and forms with a keyboard, and see where they are on the page.
• Unclear links and buttons. Several links that all read “more” or “here”, or icon-only buttons with no accessible name are confusing out of context.
• Heading structure. Headings used for visual styling rather than structure make pages hard to navigate with assistive technology.
• Video without captions. Auto-generated captions are a start but need checking.

A note on accessibility overlays

Overlay widgets that promise instant compliance with a single line of code are heavily marketed to small businesses. Many accessibility specialists and disabled users are critical of them, because they do not fix the underlying code and can interfere with the assistive technology people already use. Businesses using overlays have still received legal complaints. Fixing the site itself is the more reliable route.

How to get started

Run your key pages through a free automated checker, such as WAVE or the accessibility audit in Chrome’s Lighthouse. Automated tools find only part of the problems, but they catch common ones like contrast and missing labels. Then try using your site with only a keyboard and, if you can, with a screen reader such as VoiceOver or NVDA. Prioritise the paths that matter commercially: finding a service, contacting you, buying. Build accessibility into future design and content work so new pages do not reintroduce old problems.

On WordPress, theme and plugin choices make a big difference. Some themes and page builders produce markup that is difficult to make accessible, which is worth considering at your next redesign. Accessibility fixes are also part of keeping a site well maintained, as we explain in what WordPress maintenance involves.

Making your website usable by everyone

Accessibility is easiest and cheapest when it is built in rather than bolted on. Our website design and development work follows WCAG AA principles from the start, and our WordPress development team can audit and fix existing sites, starting with the pages your customers use most.
