Why Website Accessibility Matters: Make Your Site Inclusive, Legal, and SEO-Friendly

Website accessibility means designing and developing websites so that everyone—including people with visual, auditory, cognitive, and motor impairments—can use them. This involves everything from screen reader compatibility and keyboard navigation to colour contrast, text size, and semantic HTML (WebAIM: Introduction to Web Accessibility).

Why Website Accessibility Matters: Make Your Site Inclusive, Legal, and SEO-Friendly

Why Accessibility Is So Important

Accessibility isn’t just about ticking a box; it’s about ensuring equal access to content and services on the web.

1. It’s the Right Thing to Do

Over 14 million people in the UK live with a disability. Excluding this demographic, whether intentionally or not, limits their access to information, services, and online shopping. Accessibility is inclusion.

2. It’s the Law

Failing to make your website accessible could lead to legal consequences under:

  • The Equality Act 2010 (UK): Requires reasonable adjustments to ensure disabled users are not disadvantaged.

  • Public Sector Bodies (Websites and Mobile Applications) Accessibility Regulations 2018: Enforceable guidelines for public websites.

Legal cases in the UK are increasing, with some businesses forced to overhaul sites following complaints.

3. Boosts SEO

Search engines favour accessible websites. Why?

  • Semantic HTML improves crawlability.

  • Alt text supports both screen readers and image indexing.

  • Structured content (headings, ARIA landmarks, skip links) improves both user experience and site hierarchy.

Google sees accessibility features as indicators of quality. What benefits users with impairments also boosts page speed, mobile usability, and SEO rankings (Moz: SEO and Accessibility).

4. Improves User Experience for Everyone

Accessible websites are clearer, faster, and easier to use for all users. Examples include:

  • Keyboard shortcuts helping power users.

  • Transcripts helping users in noisy environments.

  • Larger tap targets helping users on small screens.

Steps to Improve Your Website’s Accessibility

Start here to make your site accessible:

  • Use semantic HTML5 elements (like <nav>, <main>, <footer>)

  • Ensure good colour contrast (WCAG 2.1 AA minimum)

  • Add alt text for all images

  • Implement keyboard navigation

  • Use ARIA attributes where necessary

  • Provide skip navigation links

  • Ensure your site works well with screen readers
