Web Accessibility in 2025: Practical, People-First Guide to WCAG 2.2

Over 1.3 billion people worldwide live with some form of disability (WHO) — and for many, the web remains a barrier rather than a gateway. Web accessibility ensures your site can be used by everyone, regardless of ability.

But accessibility isn’t just a legal requirement or an ethical checkbox. It’s also a powerful business driver: accessible websites rank higher on Google, convert better, and build stronger brand trust.

At DBETA, we’ve seen accessibility transform not just websites, but entire customer journeys — from smoother navigation to higher conversions and deeper engagement.

This guide will show you what accessibility means in 2025, why it matters more than ever, and the practical steps you can take to make your site both inclusive and SEO-friendly.

Why Accessibility Matters in 2025

Accessibility is no longer optional — it’s essential for users, businesses, and society. Here’s why it should be at the core of your digital strategy:

• Inclusivity: Over 1.3 billion people globally live with a disability (WHO). Accessibility ensures individuals with visual, auditory, cognitive, or motor impairments can engage with your site.
• SEO advantage: Features like descriptive alt text, transcripts, and semantic HTML not only support screen readers but also improve how search engines understand and rank your pages.
• Legal protection: Accessibility lawsuits rose by 30% in 2024 (UsableNet). Compliance with WCAG 2.2 — and soon 3.0 — helps you stay ahead of regulations.
• Better user experience: Clear navigation, readable fonts, and logical structure make your site easier to use for everyone, not just those with disabilities.
• Business growth: The global disability market represents $8 trillion in annual disposable income (Return on Disability). Making your site accessible ensures you’re not shutting out this audience.

Example from our work: A retail brand we partnered with saw an 18% increase in conversions after improving accessibility — achieved by enhancing keyboard navigation and optimising colour contrast in product descriptions.

Core Principles of Accessibility (POUR)

The Web Content Accessibility Guidelines (WCAG) are built around four principles, known as POUR. These ensure your website works for everyone — across abilities, devices, and contexts:

• Perceivable: Information must be presented in ways users can sense.
  Example: Add text alternatives for images so screen readers can describe them to visually impaired users.
• Operable: Interfaces must be usable via multiple methods.
  Example: Make all menus, forms, and buttons keyboard-friendly so users who cannot use a mouse can still navigate.
• Understandable: Content and design must be predictable and clear.
  Example: Use consistent navigation across all pages and avoid jargon in form labels or instructions.
• Robust: Content should remain accessible as technology evolves.
  Example: Ensure your site works with current and future browsers, mobile devices, and assistive technologies.

Pro tip: At DBETA, we bake POUR into every stage of design using our DBETA Bones 8.0, which ensures semantic markup, accessible colour palettes, and responsive layouts by default.

Practical Steps to Make Your Website Accessible

1. Structure and Navigation

A clear, logical structure makes your website easier for everyone to use — and is essential for people relying on screen readers or keyboard navigation.

• Use heading hierarchy (H1 > H2 > H3): Screen readers use headings to give users an outline of the page. If headings are skipped or out of order, it’s disorienting.
  Example: Use one H1 for the page title, H2s for major sections (like “Why Accessibility Matters”), and H3s for subsections.
• Keep navigation consistent and simple: Menus should be in the same place across the site and labelled clearly (e.g., “Contact Us” instead of “Let’s Talk”). Predictability builds trust and reduces confusion.
• Add breadcrumb trails: Breadcrumbs show users where they are in the site hierarchy, which helps everyone — but especially users with cognitive impairments who benefit from extra orientation.

2. Alt Text and Images

Alt text (alternative text) describes images so users who are blind or visually impaired can understand what’s on the page. It also helps search engines interpret image content and even serves as fallback text if an image doesn’t load.

• Be descriptive and concise: Explain the content and purpose of the image, not just what it is.
  Example: Instead of “Image of window”, write “Energy-efficient triple-glazed window installed in a modern home.”
• Skip decorative images: If an image is purely decorative (e.g., background pattern), leave the alt attribute empty (alt="") so screen readers skip it.
• Avoid keyword stuffing: Alt text is not a place to cram SEO keywords — it should serve the user first.
• Describe function, not appearance: For clickable images (e.g., buttons, icons), describe the action (“Search” or “Submit form”) rather than the visual.

3. Transcripts and Captions

Captions and transcripts make your multimedia content accessible to people with hearing impairments — but their benefits go far beyond that. They improve comprehension for non-native speakers, make content usable in sound-off environments (like commuting), and even boost SEO by providing indexable text for search engines.

• Always provide captions for video: Use closed captions so viewers can turn them on or off. Ensure timing matches the spoken words.
• Offer transcripts for audio content: Podcasts, webinars, and interviews should include a downloadable transcript. This helps both accessibility and search visibility.
• Ensure accuracy: Auto-captioning tools (like YouTube’s) are a good start but often misinterpret technical terms or names. Always review and edit captions.
• Add speaker identification: For group discussions, label who’s speaking (e.g., [John]: vs. [Anna]:). This prevents confusion.
• Don’t forget sound effects: Note meaningful sounds (e.g., [applause], [door slams]) to provide full context.

4. Colour Contrast and Readability

Colour contrast plays a huge role in accessibility. Users with visual impairments, colour blindness, or even just bright outdoor lighting need clear text that stands out from the background. Poor contrast is one of the most common accessibility failures flagged in audits.

• Maintain at least 4.5:1 contrast ratio: For normal text (WCAG 2.1). Large text (over 18px) may use a 3:1 ratio.
• Avoid colour-only cues: Never rely on colour alone to show meaning. For example, an error field shouldn’t just turn red — add an error message like “Please enter a valid email.”
• Choose readable fonts and spacing: Use legible font sizes (at least 16px body text), good line spacing (1.5x), and avoid low-contrast colour combinations like light grey on white.
• Test before publishing: Tools like WebAIM Contrast Checker or Stark (Figma/Sketch plugin) quickly show if your colours pass WCAG standards.
• Account for real-world conditions: Text that looks fine on a desktop monitor may wash out on mobile in sunlight. Always test on multiple devices.

5. Keyboard Accessibility

For many users — including people with motor impairments, vision loss, or repetitive strain injuries — a mouse isn’t an option. That’s why your site must be fully navigable with a keyboard alone. Even for everyday users, keyboard shortcuts can speed up browsing, making accessibility a universal benefit.

• Ensure full navigation with the Tab key: Users should be able to move through menus, forms, buttons, and links in a logical order.
• Keep focus visible: Highlight the active element with a clear focus indicator (outline or highlight), so users always know where they are on the page.
• Don’t trap users: Modals, popups, or dropdowns must allow keyboard users to exit easily (e.g., pressing Esc).
• Test your site without a mouse: Navigate using only the keyboard (Tab, Shift+Tab, Enter, and arrow keys). If you get stuck, so will your users.
• Use accessibility testing tools: Axe or Lighthouse can flag missing focus states or inaccessible interactive elements.

6. ARIA Landmarks and Labels

ARIA (Accessible Rich Internet Applications) attributes help assistive technologies understand your website’s structure and functionality. They’re especially important for complex layouts, forms, and interactive elements.

• Use ARIA landmarks: Add roles like role="navigation", role="main", and role="banner" so screen reader users can quickly jump between key sections of a page.
• Label interactive elements: Use aria-label or aria-labelledby for buttons, icons, and form inputs that aren’t otherwise clear.
  Example: A search button with only a magnifying glass icon should have aria-label="Search".
• Don’t overuse ARIA: Whenever possible, use semantic HTML (<header>, <main>, <footer>, <nav>) before adding ARIA roles. Misusing ARIA can make sites less accessible.
• Test with screen readers: Tools like NVDA, JAWS, or VoiceOver will confirm whether ARIA attributes provide the intended context.

7. Form Accessibility

Forms are one of the biggest barriers to accessibility. If they’re not designed properly, users with visual, cognitive, or motor impairments may be completely unable to complete them — which often means lost customers or failed conversions.

• Use clear labels: Every form field should have an explicit label linked to it (using the <label> element). Placeholders alone are not enough, as screen readers may skip them.
  Example: Instead of relying on “Email” greyed-out text inside a field, use a visible label above it.
• Accessible error messages: Errors should be descriptive and announced to screen readers. Avoid vague “Error!” alerts in red. Instead, write “Please enter a valid email address in the format name@example.com.”
• Inline validation: Provide feedback as the user types, so issues are flagged before submission. This reduces frustration and abandonment.
• Group related fields: Use <fieldset> and <legend> for grouped inputs (like address fields) to give context to screen readers.
• Make required fields clear: Use both visual indicators (like an asterisk) and text (“required”) instead of colour alone.
• Ensure keyboard and screen reader compatibility: Users should be able to tab through inputs in a logical order, with focus indicators visible.

8. Motion, Animations, and Interactions

Animations and interactive effects can make a website feel dynamic — but they can also create serious barriers. Users with vestibular disorders, ADHD, epilepsy, or visual sensitivities may experience discomfort, distraction, or even health risks when exposed to certain motion patterns.

• Provide motion controls: Allow users to pause, stop, or disable non-essential animations (carousels, background video loops). This is required by WCAG 2.2.
• Respect system preferences: Use CSS media queries like prefers-reduced-motion so animations automatically reduce for users who have chosen this setting in their device preferences.
• Avoid flashing or strobing effects: WCAG 2.3 requires avoiding content that flashes more than 3 times per second, which can trigger seizures.
• Ensure interactive components are accessible: Sliders, carousels, and accordions must work with keyboard navigation and screen readers. Provide clear instructions where necessary.
• Balance creativity with control: Animations should enhance storytelling, not overwhelm or distract users. Subtle transitions often work better than flashy effects.

9. Mobile and Touch Accessibility

With over half of global web traffic coming from mobile devices, accessibility on touchscreens is critical. Users with limited dexterity, tremors, or motor impairments may struggle to tap small or tightly spaced elements — leading to frustration and drop-offs.

• Use adequate tap targets: Follow Apple’s guideline of at least 44px by 44px for buttons, links, and form inputs. Larger tap areas reduce accidental taps and improve usability for all users.
• Avoid hover-only interactions: Many users browse exclusively on touch devices. If a dropdown menu or tooltip relies on hovering, it becomes inaccessible on mobile. Provide a tap-based alternative.
• Space interactive elements properly: Leave enough padding between links or buttons so users don’t accidentally hit the wrong one.
• Support multiple input methods: Ensure your site works with touch, stylus, voice commands, and external keyboards.
• Design responsively: Mobile accessibility isn’t just about resizing — layouts should adapt so text remains readable without pinch-zooming.

10. Accessible PDFs and Downloads

Accessibility doesn’t stop at your website. If you share guides, brochures, or reports as downloadable files, these need to be just as accessible as your online content. A poorly tagged PDF can be unreadable to someone using a screen reader, making vital information completely inaccessible.

• Use tagged PDFs: Structure the document with proper headings, lists, and tables so assistive technologies can interpret them correctly.
• Add alternative text for images: Just like on a website, visuals in PDFs should have descriptive alt text.
• Set the correct reading order: Screen readers follow the tag order, not the visual layout. Ensure the content flows logically.
• Define document language: Specify the document’s main language so screen readers apply correct pronunciation rules.
• Use accessible fonts and contrast: Ensure text is readable at different zoom levels and complies with WCAG contrast standards.

11. Testing with Real Users

Automated accessibility tools are a great starting point, but they only detect about 30% of potential issues. Many barriers can only be uncovered through real-world testing with people who rely on assistive technologies every day.

• Go beyond automation: Tools like Axe or Lighthouse won’t flag confusing error messages, inconsistent navigation, or content that overwhelms users with cognitive impairments. Real people will.
• Test with assistive tech users: Invite participants who use screen readers (NVDA, JAWS, VoiceOver), voice navigation (Dragon NaturallySpeaking), or switch devices to interact with your site.
• Use moderated usability sessions: Observe users completing key tasks (checkout, form submission, content navigation) and note where barriers appear.
• Collect feedback loops: Follow up with surveys or interviews to capture the emotional side of the experience — frustration points often go deeper than technical errors.
• Learn and improve: Document findings in an accessibility log. Fixes aren’t one-offs — they should inform your design process going forward.

12. Ongoing Accessibility Policy

Accessibility isn’t a one-time project — it’s a long-term commitment. A clear accessibility policy or statement not only signals compliance but also builds trust with users, regulators, and search engines. It shows you take inclusion seriously and provides a way for people to raise concerns.

• Publish an accessibility statement: Outline your organisation’s commitment to accessibility and the standards you follow (e.g., WCAG 2.2 AA).
• Include a contact channel: Provide an email address, form, or phone number so users can report issues or request alternatives.
• Update regularly: Policies should evolve alongside new features, content, and accessibility standards (e.g., WCAG 3.0).
• Show transparency: If your site isn’t fully compliant yet, acknowledge it and share your roadmap for improvements.

DBETA insight: We help clients create tailored accessibility statements as part of their compliance package. In DBETA Bones 8.0, we also log accessibility fixes into ongoing maintenance workflows, ensuring that policy commitments are backed by real technical action.

13. Accessibility Testing Across Devices & Browsers

Accessibility must hold up across real-world conditions — not just in the ideal setup your developers use. Different devices, browsers, and assistive technologies interpret code differently, which can make or break the user experience.

• Test across devices: Check desktops, laptops, tablets, and smartphones to ensure features remain accessible and layouts remain responsive.
• Cross-browser testing: Validate in Chrome, Firefox, Safari, and Edge — small variations can cause big issues in accessibility.
• Assistive technology combinations: Screen readers behave differently depending on the browser. For example, NVDA pairs best with Firefox, while JAWS is commonly used with Chrome or Edge.
• Check responsiveness: Ensure text remains readable and interactive elements stay usable without pinch-zooming or horizontal scrolling.
• Test under real conditions: Simulate low bandwidth or poor lighting to uncover hidden barriers.

DBETA insight: We run accessibility stress-tests in Chrome, Safari, and Firefox, combined with screen readers like NVDA, JAWS, and VoiceOver. This multi-environment approach means we catch issues that automated tools miss — ensuring clients’ sites work for real people, not just in theory.

14. Accessibility for Emerging Tech (2025 Focus)

As technology evolves, so do the expectations for accessibility. Looking beyond traditional websites, the next wave of digital experiences — from AI-driven tools to immersive AR/VR — must be designed with inclusivity at their core.

• Voice navigation: With smart assistants and browser voice control on the rise, websites should support voice commands for navigation and form interactions. Labels and landmarks need to be clear so commands like “Go to main menu” or “Click Contact Us” work reliably.
• AI-driven accessibility: Tools that auto-generate captions, transcripts, and alt text are becoming more accurate, but they still need human review. AI can reduce effort, but unchecked automation risks inaccurate or even misleading descriptions.
• AR/VR inclusivity: Immersive experiences bring new challenges. Designers must consider users with motion sensitivity, provide text or audio alternatives to visual cues, and ensure 3D interactions are navigable with assistive devices.

DBETA insight: We’re already building accessibility into next-generation frameworks by testing voice navigation compatibility and integrating AI-assisted alt text (always paired with human editing). As AR/VR moves into mainstream business websites, we’re preparing workflows that ensure immersive storytelling remains inclusive.

15. Business Case & ROI of Accessibility

Accessibility isn’t just a compliance requirement — it’s a smart business decision. Investing in inclusive design delivers measurable returns while protecting against financial and legal risks.

• A global market worth $8 trillion: People with disabilities and their families control an estimated $8 trillion in annual disposable income (Return on Disability). An inaccessible website means shutting the door on a vast customer base.
• SEO and conversion benefits: Accessible features — such as alt text, semantic HTML, and transcripts — overlap with SEO best practices. This means better rankings, more traffic, and higher engagement.
  Example: One retail client we worked with saw an 18% uplift in conversions after improving accessibility in navigation and product descriptions.
• Reduced legal risk: In 2024, UK businesses saw a 20% rise in accessibility-related lawsuits (UsableNet). Aligning with WCAG 2.2 (and soon 3.0) protects you from costly claims and reputational damage.
• Operational efficiency: Accessibility reduces customer service friction. For example, clear error messaging in forms lowers support requests and abandoned transactions.

DBETA insight: We position accessibility as part of our growth strategy for clients. By combining compliance with design enhancements, we’ve helped businesses expand reach, strengthen SEO, and future-proof their digital presence against legal risks.

16. Accessibility & Content Creation

Accessibility isn’t only a developer’s job. The words, images, and structure chosen by content creators directly affect how inclusive your website is. Marketers, copywriters, and editors play a critical role in making content usable for all.

• Write meaningful alt text: Go beyond “Image of…” and describe the purpose of the image.
  Example: “Eco-friendly triple-glazed window installed in a modern home.”
• Use plain, clear language: Keep sentences short and avoid jargon where possible. This benefits users with cognitive impairments and makes your content easier for everyone to scan and understand.
• Structure headings properly: Headings (H1, H2, H3) aren’t just for design — they provide a roadmap for screen readers and help users navigate your content.
• Make links descriptive: Avoid vague “Click here.” Instead, write “Download our accessibility checklist” so users know what to expect.
• Check readability: Aim for a reading level that works for the widest audience. Tools like Hemingway or Readable can help.

DBETA insight: We don’t just build accessible frameworks — we coach our clients’ content teams on accessibility best practices. In our CMS setup, for example, editors are prompted to add alt text and follow the heading hierarchy, reducing the chance of inaccessible content slipping through.

17. Accessibility Beyond the Website

Accessibility doesn’t stop at your homepage. Every digital touchpoint — from emails to social media to apps — needs to be inclusive. Failing to do so risks excluding users at crucial points in their journey.

• Emails: Many people access emails with screen readers. Add descriptive alt text for images, avoid image-only emails, and ensure sufficient colour contrast in your templates. Plain-text alternatives should always be available.
• Social media posts: Platforms like Twitter (X), LinkedIn, and Instagram now allow alt text for images. Use it. Add captions to videos and avoid relying on emojis or hashtags alone to convey meaning.
• Apps: If your brand uses mobile or web apps, follow accessibility guidelines for iOS (Apple Human Interface Guidelines) and Android (Material Design Accessibility). This includes labelled buttons, logical navigation, and support for assistive tech like VoiceOver and TalkBack.

DBETA insight: We advise clients to take a “whole-journey” approach to accessibility. It’s not enough for the website to be compliant if emails, social media, or apps create barriers. In practice, this means training content teams to add image descriptions on social, building email templates with tagged structures, and testing apps with screen readers on both iOS and Android.

18. Accessibility Maintenance Checklist

Accessibility isn’t a one-off project — it’s an ongoing commitment. Every time you add new content, features, or design elements, you risk introducing new barriers. A simple maintenance routine keeps your site compliant, usable, and trustworthy.

• Review new images: Ensure all added visuals include meaningful alt text.
• Re-check colour contrast: After design updates, confirm text and buttons meet WCAG contrast ratios.
• Test navigation: Verify menus, links, and breadcrumbs still follow a logical order after new features or pages go live.
• Forms: Check that new or updated forms have labels, error messages, and keyboard compatibility.
• Multimedia: Confirm transcripts and captions exist for any new videos, podcasts, or webinars.
• Mobile & touch: Test tap targets and layouts on phones and tablets after responsive tweaks.
• Keyboard audit: Navigate the site without a mouse to confirm interactive elements remain accessible.
• Cross-browser/device test: Run spot checks in Chrome, Safari, and Firefox with at least one screen reader.

DBETA insight: As part of our DBETA Bones 8.0 maintenance cycle, we embed accessibility checks into regular QA sprints. This means issues are caught early, keeping clients compliant and ensuring accessibility commitments don’t slip over time.

Why Accessibility Matters to Us

For us at DBETA, accessibility isn’t just about checklists or compliance — it’s about people. Every website we design is meant to be an experience, and that experience should be open to everyone, regardless of ability.

We’ve seen first-hand how small accessibility barriers can shut people out. In one client project, a customer using a screen reader couldn’t complete a checkout because the “Add to Basket” button wasn’t properly labelled. Fixing something that simple didn’t just solve a technical issue — it restored someone’s ability to shop independently. That’s what accessibility is really about: dignity, equality, and inclusion.

DBETA reflection: By embedding accessibility into our DBETA Bones 8.0 and client workflows, we make sure these issues aren’t left to chance. It’s not an afterthought — it’s how we build.

For us, accessibility is more than good practice. It’s part of creating the kind of internet we want to see: inclusive, ethical, and empowering.

Tools and Resources for Accessibility

Even with best intentions, it’s easy to miss accessibility issues. Thankfully, there are excellent tools and resources to help you audit, learn, and continuously improve your site. Here are our go-to recommendations:
