Designing For Accessibility Benefits Users & SEO

Creating a website that works for everyone is no longer optional – it’s essential. Accessibility by design ensures your site is usable for people with disabilities, while also improving usability, engagement, and search engine visibility.

This guide covers key design principles, practical tips, and ways to audit your website’s design to ensure inclusivity.

Why Design For Accessibility Matters

Accessible design removes barriers for users with disabilities, including:

  • Visual impairments (blindness, low vision, color blindness)
  • Hearing impairments
  • Cognitive or learning difficulties
  • Motor limitations

Accessible website design also benefits all users: better readability, intuitive navigation, faster load times, and mobile-friendliness. Plus, as we discussed in our SEO & Accessibility blog, accessible websites naturally perform better in search engines.

Core Principles Of Accessible Design

1. Perceivable

Users must be able to perceive the content.

  • Text alternatives for images: Use descriptive alt text for every image.
  • Captions for multimedia: Add captions or transcripts for video/audio content.
  • Color contrast: Ensure text contrasts sufficiently with the background for readability.

Example: A flower shop website uses high-contrast text over product images and includes alt text describing the flowers.

2. Operable

Users should be able to interact with all site elements.

  • Keyboard navigation: All menus, forms, and interactive elements should be usable without a mouse.
  • Clear focus indicators: Buttons and links must show visual cues when selected.
  • Avoid time-sensitive actions: Give users enough time to read and interact with content.

Example: A local power tool supplier ensures their e-commerce checkout can be completed entirely via keyboard, helping both accessibility and mobile users.

3. Understandable

Content and interface should be easy to read and comprehend.

  • Consistent layout and navigation: Helps users anticipate where information will be.
  • Readable fonts: Use simple, legible fonts with sufficient size and line spacing.
  • Clear instructions: Forms, buttons, and calls-to-action should use plain language.

Example: A wine and spirits merchant presents product categories in a simple, predictable layout and labels buttons clearly (“Add to Basket” rather than “Submit”).

4. Robust

Content must work across devices and assistive technologies.

  • Semantic HTML: Proper use of headings, lists, and landmarks helps screen readers interpret content.
  • Responsive design: Ensures the site works on all devices, from desktops to smartphones.
  • Regular testing: Use accessibility tools and assistive devices to check compatibility.

Example: A water garden plant supplier ensures their site layout scales for mobile users, keeping menus and forms fully accessible.

Practical Design Tips For Accessibility

Here’s a quick checklist to make your website more accessible:

Area Tip

Accessibility In Action: Local Business Examples

Accessible design isn’t just ethical, it can also boost local SEO and engagement for small businesses. Here’s how some types of Herefordshire businesses can apply it:

  • Florist: High-contrast product images with alt text, easy-to-use online ordering form.
  • Wine & Spirits Merchant: Clearly structured product pages, keyboard-accessible checkout.
  • Power Tool Supplier: Instructional videos with captions, accessible product guides.
  • Local Hamper Supplier: Simple, readable menus and checkout forms with descriptive buttons.
  • Fermented Food Producer: Transcripts for recipe videos and product explanations.

Each of these design choices makes the site more inclusive while also helping search engines understand content, linking directly to SEO benefits.

Tools To Test & Improve Accessibility

Regular testing ensures your website remains accessible. Recommended tools include:

  • Google Lighthouse: Free auditing tool for accessibility, SEO, and performance.
  • WAVE Accessibility Checker: Browser extension to visualize accessibility issues.
  • AXE Accessibility: Comprehensive accessibility testing suite.

Regular testing helps fix issues early, prevents accessibility pitfalls, and aligns design with SEO goals.

Accessible design is good for users, business, and search engines. By following WCAG principles, using proper contrast, readable fonts, clear navigation, and semantic code, your website becomes inclusive and easier to rank.

Accessible design is a win-win: it increases engagement, reduces bounce rates, and opens your site to a broader audience – all while supporting SEO.
