Web accessibility is not a nice-to-have feature — it is a fundamental part of building a website that works for everyone. Roughly one in four adults in the United States lives with some form of disability, and many of them rely on assistive technology to browse the web. If your WordPress site creates barriers for those users, you are excluding a significant portion of your potential audience and exposing your business to legal risk.

The good news is that WordPress, by design, already handles some accessibility basics. But themes, plugins, and custom content can easily undo that foundation. This guide walks you through everything you need to know to audit, fix, and maintain an accessible WordPress website.

What Web Accessibility Actually Means

Web accessibility means that people with disabilities — including visual, auditory, motor, and cognitive impairments — can perceive, understand, navigate, and interact with your website. The global standard is the Web Content Accessibility Guidelines (WCAG), currently at version 2.2. Most legal and compliance frameworks reference WCAG Level AA as the baseline.

WCAG is organized around four principles, often abbreviated as POUR:

  • Perceivable — Content must be presented in ways users can perceive, such as providing alt text for images and captions for video.
  • Operable — All functionality must work with a keyboard, and users must have enough time to interact with content.
  • Understandable — Text must be readable, navigation must be predictable, and forms must help users avoid and correct errors.
  • Robust — Content must be compatible with current and future assistive technologies, including screen readers.

Common Accessibility Problems on WordPress Sites

Many WordPress sites fail basic accessibility checks without the owner realizing it. Here are the issues we encounter most often when auditing client websites:

Missing or Unhelpful Alt Text

Every image on your site needs an alt attribute that describes the image’s purpose. Decorative images should have an empty alt attribute (alt="") so screen readers skip them. Stock photos with alt text like “IMG_4532.jpg” or “photo” provide no value. Write alt text that describes what the image shows in the context of your page.

Poor Color Contrast

Text needs sufficient contrast against its background to be readable by people with low vision or color blindness. WCAG AA requires a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Many themes use light gray text on white backgrounds that fail this threshold. Use a contrast checker tool to verify your color combinations.

Broken Heading Hierarchy

Screen reader users often navigate pages by jumping between headings. If your headings skip levels — going from H1 to H3, for example — or if you use heading tags purely for visual styling, the page structure becomes confusing. Every page should have one H1 (usually the title), followed by H2s for major sections and H3s for subsections, in logical order.

Inaccessible Forms

Contact forms, search bars, and checkout forms are common failure points. Every form field needs a visible label (not just placeholder text, which disappears when you start typing). Error messages should clearly explain what went wrong and how to fix it. Required fields should be identified in a way that does not rely solely on color.

Missing Keyboard Navigation

Users who cannot use a mouse rely on keyboard navigation. Every interactive element — links, buttons, form fields, menus — must be reachable and operable with the Tab key. Focus indicators (the outline that shows which element is selected) should be clearly visible. Many themes remove the default focus outline for aesthetic reasons, which makes keyboard navigation nearly impossible.

How to Audit Your WordPress Site for Accessibility

Before you start fixing things, you need to know where the problems are. A thorough accessibility audit combines automated tools with manual testing.

Automated tools catch many common issues quickly. Start with one of these:

  • WAVE (wave.webaim.org) — A free browser extension that highlights accessibility errors directly on your page.
  • axe DevTools — A browser extension that provides detailed reports and remediation guidance.
  • Lighthouse — Built into Chrome DevTools, the accessibility audit covers many WCAG criteria.

Manual testing catches things automated tools miss. At minimum, try navigating your entire site using only your keyboard. Can you reach every link and button? Can you see where the focus is at all times? Can you open and close menus? Also test with a screen reader — VoiceOver on Mac or NVDA on Windows are both free.

WordPress Plugins That Improve Accessibility

Plugins can help, but they are not a silver bullet. No overlay or widget can make a fundamentally inaccessible site fully compliant. That said, these plugins address real issues:

  • WP Accessibility — Adds skip links, fixes some common theme issues, removes title attributes from images, and helps enforce alt text.
  • One Stop Accessibility — Provides a front-end toolbar that lets visitors adjust font size, contrast, and spacing.
  • Jesuspended Forms (Gravity Forms, WPForms) — Most major form plugins have accessibility settings. Make sure ARIA labels and fieldset groupings are enabled.

Keep your plugins updated — outdated plugins can introduce new accessibility regressions. Our article on keeping WordPress plugins current explains why this matters for both security and usability.

Choosing an Accessible WordPress Theme

Your theme determines a large portion of your site’s baseline accessibility. When selecting or switching themes, look for these indicators:

  • The theme is tagged “accessibility-ready” in the WordPress theme directory. This means it passed a review against WordPress accessibility coding standards.
  • It uses semantic HTML elements — nav, main, header, footer, article — rather than generic div containers for everything.
  • Navigation menus support keyboard interaction out of the box, including dropdowns.
  • Focus styles are visible without needing CSS overrides.

Popular accessible themes include GeneratePress, Flavor, and the default WordPress themes (Twenty Twenty-Four, etc.), which are built with accessibility as a priority.

Writing Accessible Content in the Block Editor

Every time you publish or edit a page, you have an opportunity to improve or harm accessibility. Follow these practices in the Gutenberg editor:

  • Always fill in the alt text field when inserting images. Describe the image in context — what is it showing the reader?
  • Use heading blocks for headings, not bold text in a paragraph block. Maintain the correct hierarchy.
  • Use the list block for lists instead of manually typing dashes or numbers in a paragraph block.
  • Add descriptive link text. Avoid “click here” — instead, write links that describe the destination, like “read our guide to technical SEO.”
  • If you embed videos, make sure they have captions. YouTube generates automatic captions that you can edit for accuracy.

The Legal Side of Web Accessibility

ADA lawsuits targeting websites have increased sharply over the past several years. While the ADA does not explicitly mention websites, courts have consistently interpreted it to apply to online businesses. The Department of Justice has also issued guidance affirming that web accessibility falls under ADA Title III requirements.

Small businesses are not exempt. Demand letters from serial plaintiff law firms typically target businesses that have obvious accessibility failures — missing alt text, no keyboard navigation, and no accessibility statement. Fixing these issues proactively is far cheaper than responding to a legal complaint.

Frequently Asked Questions

Is WordPress accessible out of the box?

WordPress core follows accessibility coding standards and the default themes are tagged “accessibility-ready.” However, the theme you install, the plugins you add, and the content you create all affect the final result. Most live WordPress sites have accessibility issues that need attention.

Do accessibility overlay widgets actually work?

Accessibility overlays — the pop-up widgets that add a toolbar to your site — are widely criticized by disability advocates. They do not fix underlying code issues, can interfere with assistive technology, and may create a false sense of compliance. Investing in actual code-level fixes is more effective and more legally defensible.

How often should I test my site for accessibility?

Run an automated audit at least quarterly, and manually test after any major theme update, plugin change, or redesign. If you publish content frequently, check new pages and posts as part of your editorial workflow.

Can I make my existing site accessible without rebuilding it?

In most cases, yes. Many accessibility fixes — adding alt text, improving color contrast, fixing heading structure, adding form labels — can be done on your existing site without a redesign. However, if your theme has deep structural problems, switching to an accessible theme may be the most efficient path forward.

Take the First Step Toward an Accessible Website

Web accessibility is not a one-time project — it is an ongoing practice that benefits your users, your search rankings, and your legal standing. Start with an audit, fix the highest-impact issues first, and build accessibility into your content workflow going forward.
