What is digital accessibility — and why does it matter for your business?

Most people, when they hear "digital accessibility," think of blind users and screen readers. That is part of it — but only a small part. Digital accessibility covers the full range of ways people interact with digital products: motor impairments that make a mouse difficult to use, cognitive differences that affect how information is processed, hearing loss, colour blindness, age-related changes in vision, and conditions that are temporary or situational — a broken arm, bright sunlight on a phone screen, a noisy environment where audio is not an option.

A website or app is digitally accessible when a person with any of these differences can use it to complete the same tasks as anyone else: log in, make a purchase, read important information, contact support, book an appointment, submit a form. When a product is not accessible, those tasks become difficult or impossible. The user does not get what they need. Your organisation loses a customer, a lead, or a user — without ever knowing they were there.

Who we are talking about

These are not edge cases. In many EU countries, older people already outnumber those under 25. As EIDD — Design for All Europe has noted, accessibility is not about minority groups: it is about ignored majorities. And disability is rarely permanent or visible. A customer carrying a child, using a phone in sunlight, or recovering from surgery faces the same barriers as someone with a long-term condition. The audience for accessible design is considerably larger than most organisations realise.

What makes a digital product inaccessible

The most common barriers are not the result of deliberate exclusion. They are the result of design and development processes that do not test with assistive technology or consider diverse user needs. The Barómetro de Accesibilidad Web 2025, a study of 204 private-sector websites across seven sectors using ISO 17020-accredited methodology, identified five barriers that appear consistently across all industries:

• Interface components without name, role, or value — buttons and controls that screen readers cannot interpret 97%
• Insufficient colour contrast — text that cannot be read by people with low vision 95%
• Links without a clear or meaningful purpose — "click here" tells a screen reader nothing 85%
• Missing alt text — images with no description for users who cannot see them 77%
• Form fields without proper labels — inputs that cannot be identified by assistive technology 68%

Each of these barriers blocks a user from completing a task. A checkout process with an unlabelled form field is simply unavailable to someone using a screen reader. A button that cannot be activated by keyboard alone excludes users with motor impairments. A page with insufficient contrast is difficult or impossible to read for a significant portion of your audience.

Accessibility is not the same as compliance

Meeting a legal standard and being genuinely usable are related but different things. Research consistently shows that technically compliant products can still fail real users, because compliance is measured against criteria, not against actual experience. As AbilityNet's Robin Christopherson has observed, the gap between technical compliance and practical usability can be wide — a product may pass an automated audit and still be unusable for someone relying on assistive technology in a real-world task.

This is why user testing with disabled people matters alongside technical assessment. Standards tell you what to aim for. Users tell you whether you got there.

The commercial case

Inaccessible products have a direct commercial cost that rarely appears in any report. When a disabled user cannot complete a purchase, the abandoned transaction is invisible — they never made it to the analytics event that would have recorded the attempt. Research into e-commerce accessibility found that four in ten disabled users cannot complete an online booking task. Those are real transactions, not made.

Organisations that have addressed accessibility report reduced customer support costs, higher completion rates, and stronger customer loyalty among assistive technology users. Accessibility improvements also tend to improve search engine performance as a secondary effect, because the structural changes required for accessibility — clear headings, meaningful link text, properly labelled forms — are the same changes search engines reward.

The regulatory context

The European Accessibility Act (EAA) has been in force since June 2025. It requires organisations providing digital products or services to EU consumers to meet EN 301 549, the harmonised European accessibility standard. In practice, that means conforming to the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA — and demonstrating active management of that compliance position. Enforcement has started in several member states. In Ireland, Germany, Sweden and the Netherlands, organisations are already facing complaints, audits, and in some cases, legal demands.

The EAA is not the reason to care about accessibility. It is the reason that not caring now carries real consequences.
