An accessible website is designed so more people can understand, navigate, and use it, including people who browse with a keyboard, screen reader, zoom, voice control, captions, or adjusted colour settings. It also helps customers dealing with a temporary injury, a bright screen outdoors, a noisy environment, or a slow connection.
Accessibility is therefore more than a compliance task. Clear structure, readable content, predictable controls, and useful feedback improve the experience for everyone. They can reduce abandoned journeys, make content easier to find, and produce a website that is simpler to maintain as the business grows.
Start with the journeys that matter most
Do not begin with an abstract checklist. Identify the tasks customers most need to complete: understanding a service, requesting a quote, booking an appointment, buying a product, finding contact details, or managing an account. Test each journey from start to finish.
Prioritising real journeys connects accessibility work to business outcomes. A technically perfect footer icon matters less than a booking form that cannot be completed without a mouse or an error message that nobody can understand.
- Which pages generate enquiries, bookings, or sales?
- Where do customers abandon the process or ask for help?
- Can every essential task be completed without a mouse?
Make structure clear in both design and code
Headings, landmarks, lists, labels, and buttons give a page structure. Visual styling should reinforce that structure, while semantic HTML makes it available to assistive technology and search engines.
Use one descriptive main heading, organise sections in a logical order, and make link text meaningful outside its surrounding paragraph. Labels such as view our software services are more useful than repeated links that only say click here.
Design for keyboard and visible focus
Some people navigate entirely with a keyboard or switch device. Interactive elements should follow a sensible order, work with standard keys, and show clearly which item currently has focus.
Removing focus outlines for aesthetic reasons makes a site harder to use. A well-designed focus state can match the brand while remaining obvious against every background. Menus, dialogs, carousels, and forms deserve particular attention because custom interactions often introduce keyboard traps.
Use readable contrast and flexible text
Text needs sufficient contrast against its background, and important information should not depend on colour alone. Error states, chart categories, and selected options benefit from an icon, label, pattern, or shape as well as a colour change.
Allow text to resize without overlapping controls or hiding content. Responsive design should work at narrow widths and high zoom, not only on a standard mobile screen. Short paragraphs, descriptive headings, and generous spacing also reduce cognitive effort.
Give images and media useful alternatives
Meaningful images need concise alternative text that communicates their purpose in context. Decorative images should be ignored by assistive technology rather than described unnecessarily. The goal is an equivalent experience, not a literal inventory of every visible detail.
Video should include accurate captions, and audio-only information should have a transcript or equivalent written explanation. Avoid automatically playing sound, and ensure media controls work with a keyboard and have understandable names.
Build forms that help people recover
Forms are where many accessible journeys fail. Every field needs a persistent label, instructions should appear before they are needed, and errors should explain both what went wrong and how to correct it.
Keep entered information when validation fails, move attention to a useful error summary, and do not impose unnecessarily short time limits. For sensitive or consequential submissions, let the customer review and correct information before confirming it.
- Use visible labels rather than placeholders alone.
- Connect error messages to the affected fields.
- Ask only for information the process genuinely needs.
- Confirm success clearly after submission.
Test with tools and real people
Automated accessibility checks can quickly find missing labels, contrast failures, and invalid markup, but they cannot judge whether a journey makes sense. Combine automated testing with keyboard checks, screen-reader review, zoom testing, and testing by people with different access needs.
Treat findings as product feedback rather than a one-off audit. Record issues alongside other work, fix repeated patterns in shared components, and include accessibility in the definition of done for future changes.
Make accessibility part of ongoing quality
A website can become less accessible when new campaigns, third-party widgets, forms, and content are added. Clear publishing guidance and reusable accessible components prevent the same problems from returning.
Assign ownership, review high-value journeys regularly, and monitor customer feedback. Accessibility works best when it is part of design, content, development, and testing—not a final check just before launch.
The takeaway
Accessible design removes unnecessary barriers between customers and the outcome they came for. The same improvements—clear language, robust structure, visible feedback, flexible layouts, and dependable controls—usually make a website better for every visitor.
Start with one important customer journey, complete it using only a keyboard, and fix the first barrier you find. Small, consistent improvements can create a much more inclusive and effective digital service.
