Essential WordPress Accessibility Checklist for Shocking Legal Safety
WordPress accessibility is no longer optional — it’s a legal requirement that can make or break your online business. If your site isn’t accessible to people with disabilities, you’re not just excluding a massive audience. You’re exposing yourself to devastating lawsuits that could cost tens of thousands of dollars. In this essential guide, I’ll walk you through a complete WordPress accessibility checklist that ensures your site is WCAG 2.2 compliant, inclusive, and legally protected in 2026.

Why WordPress Accessibility Matters More Than Ever
Over one billion people worldwide live with some form of disability. That’s roughly 16% of the global population, according to the World Health Organization. When your WordPress site lacks proper accessibility features, you’re turning away a significant portion of potential customers and visitors.
But this isn’t just about audience reach. WordPress accessibility has become a critical legal and ethical responsibility. Search engines like Google have also started factoring accessibility signals into their ranking algorithms, meaning an inaccessible site can hurt your SEO performance too. Accessible websites tend to have cleaner code, better semantic structure, and faster load times — all of which contribute to higher search rankings.
From a business perspective, making your site accessible demonstrates that your brand values inclusivity. It builds trust with every visitor, not just those who rely on assistive technologies.
The Shocking Legal Landscape Around Web Accessibility
Here’s the reality that catches most business owners off guard: web accessibility lawsuits have exploded in recent years. In the United States alone, ADA-related digital accessibility lawsuits exceeded 4,000 per year, and that number continues to climb. The Department of Justice has made it clear through its official web accessibility guidance that websites must comply with ADA Title III requirements.
In Canada, the Accessible Canada Act sets strict timelines for digital compliance. The European Union’s European Accessibility Act took full effect in 2025, covering everything from e-commerce to banking websites. These aren’t suggestions — they carry real penalties for non-compliance.
Small businesses are not exempt. Plaintiff firms specifically target small and mid-sized companies because they’re less likely to have proper WordPress accessibility measures in place and more likely to settle quickly. The average settlement ranges from $5,000 to $25,000, but legal fees can push costs much higher.
The Essential WordPress Accessibility Checklist
Use this comprehensive checklist to audit and improve your site’s accessibility. Each item aligns with WCAG 2.2 guidelines at the AA conformance level, which is the standard most legislation references.
1. Images and Alt Text
Every image on your site needs descriptive alternative text. Screen readers rely on alt attributes to convey image content to visually impaired users. In WordPress, you can add alt text directly in the media library or within the block editor when inserting images.
Write alt text that describes the image’s purpose, not just its appearance. If an image is purely decorative, use an empty alt attribute (alt="") so screen readers skip it entirely. Avoid stuffing keywords into alt text — keep it natural and descriptive.
2. Heading Structure and Hierarchy
Proper heading hierarchy is fundamental to WordPress accessibility. Use H1 for your page title (WordPress handles this automatically for posts), then H2 for main sections, H3 for subsections, and so on. Never skip heading levels — jumping from H2 to H4 confuses assistive technologies and breaks the logical document outline.
If you’re using a custom WordPress theme or a page builder, double-check that your headings maintain proper hierarchy across all templates and layouts.
3. Color Contrast
Text must have sufficient contrast against its background. WCAG 2.2 AA requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18px bold or 24px regular). Use tools like the WAVE accessibility evaluation tool to check contrast ratios across your pages.
Don’t rely on color alone to convey information. If you use red to indicate errors in a form, also include an icon or text label so colorblind users understand the message.
4. Keyboard Navigation
Every interactive element on your site — links, buttons, forms, menus, modals — must be fully operable using only a keyboard. Users should be able to tab through elements in a logical order and activate them with Enter or Space. This is one of the most commonly failed WordPress accessibility requirements.
Test this yourself: put your mouse away and try navigating your entire site using only Tab, Shift+Tab, Enter, and Escape. If you get stuck or can’t reach something, your keyboard users are stuck too.
5. Forms and Labels
Every form field needs a properly associated <label> element. Placeholder text alone doesn’t count — it disappears when users start typing and isn’t reliably announced by all screen readers. Make sure error messages are descriptive and programmatically associated with the relevant field using aria-describedby.
Contact forms, search bars, login screens, and checkout pages are high-priority areas. If you’re using popular form plugins like Gravity Forms or WPForms, check their accessibility settings and enable any built-in WCAG compliance features.
6. Link Text and Focus Indicators
Avoid vague link text like “click here” or “read more.” Screen reader users often navigate by tabbing through links, so each link should make sense out of context. Write descriptive anchor text like “download our accessibility audit template” instead.
Focus indicators — the visible outline that appears around focused elements — must never be removed with CSS. If your theme uses outline: none on interactive elements, override it with a clearly visible focus style.
7. Media and Video Content
All video content needs captions, and audio content needs transcripts. If you embed YouTube videos, ensure they have accurate captions enabled. For self-hosted media, WordPress supports WebVTT caption files. Provide audio descriptions for videos that contain important visual information not conveyed through dialogue.
Testing Your WordPress Accessibility: Tools That Work
Automated testing catches roughly 30-40% of accessibility issues. You need a combination of automated tools and manual testing for thorough coverage. Here are the tools I recommend:
Automated tools: WAVE (browser extension), axe DevTools by Deque, Google Lighthouse (built into Chrome DevTools), and the WordPress Accessibility Checker plugin. Run these on every page template, not just the homepage.
Manual testing: Navigate your site using only a keyboard. Test with a screen reader — NVDA (free for Windows) or VoiceOver (built into macOS and iOS). Zoom your browser to 200% and verify nothing breaks. Check that all interactive elements have visible focus states.
Real user testing: If budget allows, recruit users who rely on assistive technologies for usability testing. No automated tool can replace the insight of someone who uses a screen reader daily.
WordPress Accessibility-Ready Themes and Plugins
WordPress.org maintains an “accessibility-ready” tag for themes that meet a baseline set of accessibility requirements. When choosing a theme, filter by this tag to start with a solid foundation. Popular accessibility-ready themes include Twenty Twenty-Five (WordPress’s default theme), flavor, and flavor themes built on the theme.json system.
For plugins, look for those that explicitly mention WCAG compliance and are regularly updated. Be cautious with accessibility overlay plugins that promise one-click compliance — the accessibility community widely criticizes these tools as ineffective band-aids that don’t fix underlying code issues and can actually worsen the experience for screen reader users.
Instead, invest time in fixing your actual code. Use semantic HTML, proper ARIA attributes where needed, and ensure your WordPress accessibility foundations are solid from the theme level up.
Common WordPress Accessibility Mistakes to Avoid
After auditing hundreds of WordPress sites, here are the mistakes I see over and over:
Missing skip navigation links. Users who navigate by keyboard shouldn’t have to tab through your entire menu on every page. Add a “Skip to content” link that appears on focus and jumps past the navigation.
Auto-playing media. Videos or audio that play automatically are jarring for everyone and especially problematic for screen reader users. Always let users choose when to play media.
Inaccessible sliders and carousels. Most slider plugins are accessibility nightmares. If you must use a carousel, ensure it’s pausable, keyboard-navigable, and announces slide changes to screen readers. Better yet, consider whether you really need a slider at all — they typically have poor engagement rates.
Missing language attribute. Your HTML tag needs a lang attribute (e.g., lang="en") so screen readers know which language to use for pronunciation. WordPress sets this automatically based on your site language settings, but verify it’s correct.
Broken zoom. Never use maximum-scale=1 in your viewport meta tag. Users with low vision need to zoom in, and preventing zoom is a WCAG failure.
Getting Started Today
WordPress accessibility doesn’t have to be overwhelming. Start with the highest-impact items: alt text for images, proper heading structure, sufficient color contrast, and keyboard navigation. These four areas alone will address the majority of common accessibility barriers.
Schedule a quarterly accessibility audit using the tools mentioned above. Make accessibility part of your development workflow rather than an afterthought. Every new page, post, or feature should be tested for accessibility before it goes live.
The combination of legal risk, audience reach, and SEO benefits makes WordPress accessibility one of the smartest investments you can make for your website in 2026. Don’t wait for a demand letter to take action.
