In the UK, 1 in 5 people have a disability that affects how they use the internet. That’s roughly 14 million potential customers. If your WordPress site isn’t accessible, you’re not just excluding people — you’re losing business. Under the Equality Act 2010, UK businesses have a legal duty to make reasonable adjustments for disabled users.

Common accessibility issues on WordPress sites: missing alt text on images (screen readers can’t describe what’s shown), poor colour contrast (text that’s hard to read for people with low vision), keyboard navigation problems (some users can’t use a mouse), missing form labels (screen readers don’t know what to enter), and auto-playing media.

Quick wins that

Make a big difference: add descriptive alt text to every image, ensure sufficient colour contrast (4.5:1 ratio minimum for normal text), make all interactive elements keyboard-accessible, use proper heading hierarchy (H1, H2, H3 in order), and ensure form fields have visible labels.

WordPress-specific accessibility improvements: choose an accessibility-ready theme (WordPress.org marks these). Use the built-in accessibility features in the block editor. Install an accessibility checker plugin. Test your site with a screen reader. Ensure your navigation menu works with keyboard only.

Accessibility and SEO go hand in hand

Alt text helps Google understand images, proper heading structure helps crawlers understand content, and fast page loads benefit everyone. Making your site accessible isn’t just the right thing to do; it’s good for your search rankings and your bottom line.

Frequently Asked Questions

Under the Equality Act 2010, UK businesses have a duty to make reasonable adjustments for disabled users — this extends to websites. While there is no specific law mandating WCAG compliance for private sector businesses, an inaccessible website that prevents disabled customers from accessing services or making purchases could constitute unlawful discrimination. Public sector websites in the UK have a stricter legal obligation (WCAG 2.1 AA compliance under the Public Sector Bodies Accessibility Regulations 2018). For private businesses, the reasonable adjustment duty and the business case (1 in 5 UK adults have a disability) make accessibility investment commercially prudent.

What are the most common WordPress accessibility issues?

The five most common accessibility issues on WordPress sites: missing or inadequate alt text on images (screen readers cannot describe images without it), poor colour contrast (text that is difficult to read for users with low vision — minimum contrast ratio is 4.5:1 for normal text), keyboard navigation failures (users who cannot use a mouse cannot navigate menus, forms, or interactive elements that only work with mouse events), missing form labels (screen readers cannot identify what input is required without explicit label elements), and auto-playing media without controls (disorienting for users with cognitive disabilities and those using screen readers).

How do I make my WordPress theme accessible?

Start with an accessibility-ready theme from WordPress.org (these are tested against accessibility criteria). Use the built-in block editor’s semantic HTML output rather than custom page builders that generate non-semantic markup. Check colour contrast with a contrast checker tool (WebAIM Contrast Checker). Add alt text to every image in the Media Library. Ensure all interactive elements (buttons, links, form fields) have visible focus states so keyboard users can track their position. Test navigation using keyboard only (Tab, Enter, Escape) to identify elements that are mouse-only. Install an accessibility checker plugin (WP Accessibility or Accessibility Checker by Equalize Digital) for automated detection of common issues.

Does WordPress accessibility improve SEO?

Yes, directly. Alt text helps Google understand image content and contributes to image search ranking. Proper heading hierarchy (H1, H2, H3 used semantically) helps crawlers understand page structure and content relationships. Descriptive link text (not “click here” but “view our WooCommerce hosting plans”) provides context that improves keyword relevance. Fast page loads benefit all users and improve Core Web Vitals scores. Semantic HTML output that screen readers can navigate is also more crawlable by search engines. Accessibility improvements align strongly with SEO best practices — the same changes that help disabled users typically help search engine understanding as well.

What tools help check WordPress accessibility?

Automated testing tools: WAVE (Web Accessibility Evaluation Tool, free browser extension), Axe DevTools (browser extension, identifies WCAG violations), Lighthouse accessibility audit (built into Chrome DevTools, scores common issues), and the Accessibility Checker plugin by Equalize Digital (WordPress-native, scans posts and pages). Manual testing: navigate your site using only the keyboard (Tab, Shift+Tab, Enter, Escape), test with a free screen reader (NVDA for Windows, VoiceOver built into Mac and iOS), and check colour contrast with WebAIM Contrast Checker. Automated tools catch approximately 30-40% of accessibility issues; manual testing is required for full coverage.
