Building a website that genuinely works for everyone is one of the most valuable things you can do for your audience and your business, and getting started with how to web accessibility does not have to be overwhelming. At We Define Net, we treat accessibility as a design and development discipline rather than a final checklist to polish off before launch. When a website is built with accessibility in mind from the start, it tends to be more usable, better optimised for search engines, and more resilient across the many devices and contexts your visitors bring to it. The framework we share here has been refined through real projects and is structured to take you from first principles to a repeatable process your team can follow on every build.

What web accessibility actually means

Web accessibility is the practice of making digital experiences usable by as many people as possible, regardless of their circumstances or the devices they use. That includes people with permanent disabilities such as blindness, low vision, deafness, motor impairments, and cognitive differences, but it also covers temporary and situational barriers. Someone with a broken arm, a parent holding a baby, a person working in bright sunlight, or an older visitor with age-related vision changes all benefit from accessible design. The international standard most professionals align with is the Web Content Accessibility Guidelines maintained by the W3C, and the current version widely referenced is WCAG 2.2 at levels A and AA. At We Define Net, we find that committing to WCAG 2.2 AA gives our clients a pragmatic, defensible standard without chasing every theoretical edge case. If you need a website built to that standard from the ground up, our website development service covers accessibility as a core part of the build, not an afterthought.

Why accessibility belongs in the brief, not the backlog

Teams that address accessibility early run into fewer costly rewrites later. Retro-fitting an inaccessible site is often harder and more expensive than building accessibly from day one. When stakeholders understand the return — broader reach, stronger compliance posture, better search performance, and reduced legal risk — accessibility moves from the bottom of the backlog to the core of the project brief. Accessibility also overlaps naturally with user experience and search engine optimisation, two areas where teams usually already have buy-in. Semantic markup, clear heading structures, descriptive link text, and well-labelled forms all serve screen-reader users and search-engine crawlers simultaneously. The disciplines reinforce each other when you design for both audiences from the start rather than treating them as separate concerns.

A step-by-step framework for accessible websites

We break the process into four sequential phases. The first phase is about establishing the structural foundations of your pages: setting the document language, confirming page titles are unique and descriptive, checking that the tab order reflects the visual flow, and making sure that landmarks like the header, navigation, main content, and footer are clearly defined. Getting this right before styling or interaction design begins prevents most of the structural problems that cascade later. Phase two turns to keyboard navigation, which is the single most important test for interactive accessibility. Every link, button, dropdown, dialog, and custom widget must be reachable and operable without a mouse. The visible focus indicator must be obvious against surrounding content, and focus must never disappear or get trapped inside a component. In phase three, the team audits visual presentation: colour contrast ratios, responsiveness under zoom conditions, the relationship between colour and meaning, and the clarity of typography and spacing. Phase four covers forms, media, and content patterns — the parts of a site that change most frequently and therefore need the clearest rules. Our SEO service team also checks semantic structure during this phase, because heading hierarchy and landmark roles are relevant to both accessibility and organic search performance. For teams looking for practical guidance on implementation, our blog covers specific accessibility topics in more depth.

Testing your website for accessibility

No single tool tells the whole story. Automated testing catches a meaningful slice of issues efficiently, but it misses many of the problems that real users encounter. A balanced testing approach combines several layers. Start with automated tools that scan for missing alt attributes, contrast failures, empty form labels, and structural violations, running these in your build pipeline as well as manually from time to time. Then move to manual keyboard testing: navigate your entire site without touching a mouse and note anywhere you get stuck, lose focus, or cannot complete a task. After that, use a screen reader on at least the most important pages. On Windows, NVDA is a free option that many accessibility professionals rely on; on macOS, the built-in VoiceOver does the job well; and on mobile, both iOS and Android include capable screen readers. Finish with real-user testing whenever possible. Observing someone who uses assistive technology navigate your site will reveal problems that no combination of tools and experts can predict. If you want to understand how content and design decisions intersect, our content writing service works with our design and development teams to keep accessibility consistent across every touchpoint.

Common accessibility pitfalls and how to avoid them

Even experienced teams fall into the same traps repeatedly, so naming them explicitly is useful. Auto-playing media without user consent is one of the most disruptive patterns on the modern web, particularly for screen-reader users who cannot easily silence it. Icon-only buttons and links without an accessible name force assistive-technology users to guess their purpose or skip them entirely. Dropdown menus that open on hover alone leave keyboard and touch users stranded. Custom controls that are built from generic div or span elements rather than native buttons or links require enormous amounts of ARIA work to make functional and still often fall short. Modal dialogs that trap focus without a clear escape route, or that do not return focus to the triggering element when dismissed, break the predictable interaction model that assistive-technology users depend on. Decorative elements — background images used for atmosphere, decorative icons, spacer elements — must be hidden from assistive technology so they do not clutter the screen-reader output. Avoiding these pitfalls is more reliable when accessibility is reviewed by someone with direct experience of assistive technology rather than relying solely on guidelines and checklists.

Accessibility maintenance and governance

An accessible website at launch can become inaccessible over time if governance does not keep pace with content changes. A new blog post with unlabelled images, a redesigned homepage with colour contrast that no longer meets the standard, or a new third-party widget with no keyboard support can all reintroduce barriers that were previously resolved. Maintaining accessibility requires a lightweight but consistent process: a brief accessibility review as part of the content publishing workflow, automated scans in your deployment pipeline, and a periodic full audit on a schedule that matches your update cadence. Training content creators, designers, and developers on the principles behind the guidelines — not just the mechanical rules — produces better long-term outcomes than enforcing a checklist people do not understand. At We Define Net, we advise clients to embed accessibility into their digital governance from the first project and to revisit it whenever a significant change is made to the site structure or design system.

The legal and business context for UK organisations

UK organisations that serve the public or operate in sectors covered by the Equality Act 2010 have a legal duty to make reasonable adjustments so that disabled people can access their services, and that duty extends to websites. The Public Sector Bodies (Websites and Mobile Applications) (No. 2) Accessibility Regulations 2018 set specific requirements for public sector bodies, and the European Accessibility Act creates additional obligations for businesses selling certain products and services. Beyond compliance, there is a clear commercial argument. A website that is difficult to navigate will lose visitors, and inaccessible forms will lose enquiries. The reputational benefit of demonstrating that your organisation takes inclusion seriously can be meaningful in competitive markets. Accessibility is not simply risk management; it is a way of reaching a broader audience with a better experience. When you are planning a new build, investing in accessible app development alongside a well-structured website ensures consistency across your digital presence.

Comparison: automated testing tools and their coverage

Choosing the right tooling depends on where you are in the development process and what kind of issues you are hunting for. The table below compares four widely used automated accessibility testing approaches across the main dimensions that matter to development teams.

Building an accessible design system

A design system that encodes accessibility decisions is one of the most efficient ways to scale good practice across an organisation. Instead of relying on each developer to remember the correct colour contrast, focus-ring treatment, or form label pattern, you codify those decisions in a shared library of components. Button components ship with visible focus states by default. Form fields include label markup and error messaging patterns. Colour tokens are named by their purpose rather than their appearance, which helps developers avoid using the wrong shade for adjacent elements. A design system does not eliminate the need for testing, but it dramatically reduces the number of avoidable mistakes introduced during implementation. If your team uses graphic design output that is built into a component library, the consistency benefits extend to accessibility outcomes as well.

Accessibility in content and copywriting

Accessibility is not solely a technical concern; the words on the page matter enormously. Heading structure provides a navigable outline for screen-reader users and should reflect the logical hierarchy of the content, not the visual styling preferences of the designer. Links should describe their destination or action rather than using generic phrases like “click here” or “read more,” because screen-reader users often navigate by pulling up a list of all links on a page. Plain language benefits everyone, but it is especially important for users with cognitive disabilities, dyslexia, or limited English proficiency. Keep sentences short, use active voice, avoid jargon unless it is unavoidable and defined, and break long passages into shorter paragraphs. Avoid using italics or capital letters for emphasis at scale, because both can be harder to read for people with certain reading difficulties. Providing a text alternative for any non-text content — charts, infographics, diagrams, audio clips — ensures that the information is available regardless of how someone accesses the page. Our content writing service applies these principles directly to client copy, and the same standards apply whether the content lives on a marketing page or inside an application.

Mobile accessibility and progressive web apps

Smartphone and tablet users bring their own accessibility needs that go beyond the desktop experience. Touch targets must be large enough for users with motor impairments — a minimum of 44 by 44 CSS pixels is the widely accepted baseline and is reflected in both WCAG 2.2 and the Apple Human Interface Guidelines. Gesture-based interactions that require complex multi-finger swipes should always have a simpler alternative, such as an on-screen button. Content should reflow gracefully at the zoom levels users choose, and horizontal scrolling should be avoided for reading content. For web applications that behave like native apps, the same accessibility rules apply: screen-reader users must be able to complete every task, focus must be managed explicitly during navigation between views, and status messages must be announced without requiring a change of focus. The distinction between a website and a web app matters less from an accessibility standpoint than the quality of the implementation beneath both.

Frequently asked questions

What does WCAG 2.2 level AA actually require?

WCAG 2.2 level AA is a set of success criteria organised around four principles often remembered by the acronym POUR: Perceivable, Operable, Understandable, and Robust. Under Perceivable, your content must be available to the senses in more than one way, including text alternatives for non-text content and sufficient colour contrast for text and images of text. Under Operable, all functionality must be available from a keyboard, users must be given enough time to read and use content, and content must not be designed in a way that is known to cause seizures. Under Understandable, text content must be readable and predictable, and websites must help users avoid and correct mistakes. Under Robust, content must be compatible with current and future user tools, including assistive technology. Each criterion has testable success conditions, and level AA represents the standard most legislation and procurement frameworks expect.

How do I test whether my website is accessible without specialist knowledge?

Start with the simplest checks that require no specialist training. Navigate your entire site using only the keyboard — the Tab key to move forward, Shift plus Tab to move back, Enter to activate links and buttons, and the arrow keys inside menus and lists. Try zooming your browser to two hundred percent and confirm that the content reflows without horizontal scrolling, that text remains legible, and that no content disappears off-screen. Check your pages with an automated tool such as the Lighthouse audit built into Chrome DevTools or the WAVE browser extension, both of which are free. These checks will catch a significant portion of common issues, and the results will give you a clear starting point for the work that still needs manual review. For a definitive answer, you will eventually want to engage an accessibility specialist who can test with screen readers and identify the kinds of issues that automated tools cannot see.

Is accessibility only relevant for public sector websites?

No. While public sector bodies in the UK have specific legal obligations under the 2018 accessibility regulations, the Equality Act 2010 applies to all providers of goods, facilities, and services, including websites. A business that operates a website accessible to customers is therefore fulfilling a legal duty that covers disabled people, and ignoring that duty creates a risk of enforcement action. Beyond the legal minimum, accessible websites reach a broader audience, deliver a better user experience, and tend to perform better in search. Accessibility is not a niche concern for government; it is a standard practice that any organisation serious about its online presence should adopt.

Can I use a website accessibility widget instead of fixing my site?

Accessibility widgets that offer a toolbar for adjusting text size, contrast, or font style can be a useful supplement for some users, but they do not address the structural barriers that make a site inaccessible in the first place. A screen-reader user cannot use an on-page toolbar to fix missing alt text, an illogical heading structure, or a custom dropdown that is not keyboard-operable. Relying on a widget as a substitute for proper accessibility work can create a false sense of compliance and does not protect an organisation from legal challenge. Widgets can have a place as part of a broader strategy, but the foundation must be a website that is built accessibly from the markup upward.

How long does it take to make an existing website accessible?

The time required depends heavily on the size of the site, the current state of the codebase, and the depth of remediation needed. A small brochure site with clean markup might be brought into compliance through focused remediation in a matter of days, while a large, complex web application with custom interactive components can take weeks or months of dedicated work. The most efficient path is usually to address the highest-impact issues first — contrast failures, missing form labels, and keyboard navigation blocks — and then work through the remaining criteria systematically. If your site is being rebuilt on a regular cycle, building accessibility into the new build is almost always faster and more cost-effective than extensive retrofitting.

Does accessible design mean my website has to look plain or basic?

Not at all. Accessible design and visually rich design are entirely compatible. WCAG sets minimum contrast ratios and requirements around spacing and target size, but it does not dictate a particular visual style. You can use photography, video, illustration, animation, and bold typography within those constraints. The key is ensuring that visual richness does not become a barrier: that text remains readable over background images, that motion can be paused or reduced for users who are sensitive to it, and that meaning is not communicated through colour alone. The best accessible websites are both beautiful and functional, because the discipline of designing for accessibility often leads to clearer, more considered design decisions that benefit every user.
