Imagine a customer who cannot use a mouse, another who relies on a screen reader, and a third who zooms text to double size because their eyesight is fading. All three want to buy from you. Whether they can depends on choices made when your website was designed and built. Accessibility is about removing those barriers, and much of it is simpler than people expect.
Why accessibility matters
People with permanent disabilities are only part of the picture. Temporary injuries, bright sunlight on a phone screen, a noisy train or simply getting older all affect how people use websites. Accessible sites tend to be clearer, faster and easier for everyone.
There is also a legal side. Laws such as the ADA in the USA, the Equality Act in the UK, the European Accessibility Act in the EU and accessibility laws in Canada have all been applied to digital services in various ways. The commonly used benchmark is the Web Content Accessibility Guidelines, known as WCAG. This article is not legal advice, but aiming for WCAG at level AA is a sensible goal for most businesses.
The four principles in plain English
WCAG is built around four ideas. Content should be:
- Perceivable: people can see or hear it in some form, such as text alternatives for images and captions for video
- Operable: people can use it with a keyboard, voice or other tools, not only a mouse
- Understandable: language, navigation and forms behave predictably
- Robust: it works with assistive technologies like screen readers
Quick wins most sites can make
- Add meaningful alt text to images that carry information; decorative images can have empty alt text
- Check colour contrast between text and background, especially light grey text on white
- Use real headings in order, so screen reader users can scan the page structure
- Label every form field clearly, rather than relying on placeholder text that disappears
- Make link text descriptive, so "Download the price list" replaces "click here"
- Caption videos and provide transcripts for audio content
- Avoid information conveyed only by colour, like red fields with no error message
Keyboard access deserves special attention
Many people navigate with the Tab key instead of a mouse. Every link, button, menu and form control should be reachable and usable by keyboard, in a logical order, with a visible focus outline showing where you are. Pop-ups and menus should be closable with the Escape key and should not trap focus. Custom-built components, like fancy sliders or dropdowns, are where keyboard support most often breaks.
Test without special skills
You can learn a lot in fifteen minutes:
- Put the mouse away and try to complete your main task, such as sending an enquiry, using only the keyboard
- Zoom the browser to a large size and check whether text overflows or content disappears
- Run a free automated checker like WAVE or Lighthouse to catch obvious issues
- Turn on the screen reader built into your phone or computer and listen to your homepage
Automated tools catch only some problems, so a manual review by someone experienced is worth arranging for important sites.
Beware of quick-fix overlays
Some products promise to make any site accessible by adding a single script. These overlays rarely fix underlying issues and can interfere with the assistive tools people already use. Fixing the site itself is the reliable path.
Build it in from the start
Accessibility is far cheaper when considered during design and development than when bolted on later. Ask your designers to check contrast and focus states in mock-ups, and ask developers to use proper HTML elements before reaching for custom code. Include accessibility checks in every new page you publish.
FAQ
Does accessibility make a website look plain?
No. Good accessibility is compatible with strong visual design. It mainly affects contrast, structure, labels and behaviour rather than style.
What drives the cost of fixing an existing site?
The size of the site, how much custom code it uses, the platform and theme, and how many documents or videos need alternatives. An audit clarifies the scope.
Are PDFs covered too?
Yes. Documents published on your site should be accessible, or offered in an accessible alternative format.
