Best Website Accessibility Tools for WordPress

A website can look spot on in the office, then quietly frustrate a visitor who cannot read its pale grey text, use its menu with a keyboard or understand a form error. That is why choosing the best website accessibility tools is about more than ticking a box. It is about removing the small barriers that stop real people becoming customers.

For a typical small business WordPress site, you do not need a cupboard full of expensive software or a three-week crash course in web standards. You need a sensible combination of automated checks, human judgement and a willingness to fix the things that matter. Think of a tool as an MOT tester. It can flag a worn tyre, but it cannot tell you whether the car is pleasant to drive in the rain.

What accessibility tools can and cannot do

Website accessibility means making a site usable by as many people as possible, including people using screen readers, keyboard navigation, zoomed text, speech input or simply a small phone screen in bright sunlight. It also tends to make life easier for everybody else. Clear headings, readable text and obvious buttons are hardly a hardship for the rest of us.

Automated tools are very good at spotting repeatable technical issues. They can identify images without alternative text, poor colour contrast, missing form labels and headings that jump about like a toddler after birthday cake. That makes them excellent for finding quick wins across a site.

They cannot reliably judge whether alternative text actually describes an image, whether a page makes sense when read aloud, or whether a confusing enquiry form is understandable. A green score is useful, but it is not a certificate that the job is done. I have seen sites with an impressive-looking score where the main navigation could not be used without a mouse. Not ideal when someone is trying to enquire from a laptop with a broken trackpad.

The best website accessibility tools to use together

There is no single winner for every business. The best approach is to use a few tools for different jobs, then act on the findings rather than collecting reports like Pokemon cards.

WAVE for a quick visual scan

WAVE is a useful first stop when you want to see likely issues displayed directly on a page. It highlights missing alternative text, empty links, heading structures and contrast warnings, so it is particularly good for understanding what is happening without needing to decipher a technical spreadsheet.

For a business owner, I would use it on the homepage, key service pages, contact page and any popular blog posts. Pay attention to errors first, then look at alerts in context. An alert is not always wrong. For example, a decorative flourish should usually have empty alternative text rather than a lengthy description of a blue squiggle.

Lighthouse for broad website health checks

Lighthouse, built into the Chrome browser’s developer tools, includes an accessibility section alongside performance, search engine optimisation and general good practice checks. I like it because accessibility does not live in isolation. A slow, awkward website with unclear buttons is usually not great for enquiries either.

Run it on important page templates, not just one page. WordPress websites often use different templates for services, posts, archives and contact forms. A lovely homepage does not rescue a booking form that has labels only visible as faint placeholder text.

Treat the score as a starting point, not a target to chase at all costs. The useful bit is the list of issues and the explanation of why each matters.

axe DevTools for more detailed testing

axe DevTools is a more detailed browser-based checker that is particularly helpful when a site has been recently redesigned or you are making regular improvements. It can catch many common code-level issues that are easy to miss by eye, including problems with buttons, labels and page structure.

This is often the tool I would use when checking work before a WordPress site goes live. It gives a developer or experienced website manager more useful detail than a basic score, while remaining readable enough to discuss with a client. If an issue appears repeatedly across every page, it is usually a theme or template problem worth fixing once rather than patching page by page.

An accessibility checking plugin for WordPress content

A WordPress accessibility checking plugin can be helpful while writing or editing pages. These tools review content inside the WordPress editor and flag issues before the page is published. That is handy for catching missing image text, skipped headings and links that say things such as “click here”.

The catch is that a plugin cannot fix a poorly built theme, navigation or third-party form. It is a useful guardrail for content editors, not a substitute for proper website work. Also check that any plugin you install is well maintained and compatible with your WordPress setup. Adding a plugin to solve every problem is how otherwise tidy websites become a game of digital Jenga.

Keyboard testing for the things tools miss

This is the free test I wish more businesses did. Put your mouse aside and use the Tab, Shift + Tab, Enter and arrow keys to move through a page. Can you see where you are? Can you open the menu, use the contact form, accept or reject the cookie notice and submit the form?

If you get trapped in a pop-up or cannot tell which button has focus, neither can a keyboard-only visitor. This takes five minutes and can reveal problems an automated report does not properly convey.

Avoid the tempting shortcut: accessibility overlays

You may have seen widgets that place a little accessibility icon on a website and promise to make everything compliant at the flick of a switch. Be cautious. Some offer helpful visitor controls, such as text sizing or contrast changes, but they do not repair the underlying website.

In some cases, overlays can interfere with screen readers, keyboard controls or a visitor’s own accessibility settings. They can also create a false sense that the work is finished. It is a bit like putting a fresh coat of paint over a sticking front door. The paint may look nice, but visitors still cannot get in.

If a tool is sold as a complete, automatic solution, ask what it actually changes in the site code, whether those changes are tested with assistive technology, and whether you can fix the source issue instead. Usually, fixing the source is the better long-term investment.

A practical accessibility check for your WordPress site

Start with the pages that influence enquiries: your homepage, main services, about page, contact page and any form or booking journey. Run WAVE or Lighthouse, then write down repeated errors rather than trying to fix every warning in a single sitting.

Next, check the basics manually. Ensure every page has one clear main heading, with sensible subheadings beneath it. Increase low-contrast text, especially small text over photographs or coloured backgrounds. Replace vague links with meaningful ones, such as “View plumbing services” rather than “Read more”. Make sure form fields have visible labels and error messages explain what needs correcting.

Then do the keyboard test. Finally, ask someone who has not been involved in the website to complete a simple task, such as finding a service and sending an enquiry. If they hesitate, get lost or ask what a button means, that is useful evidence. Accessibility is often good old-fashioned clarity wearing a slightly more technical hat.

For larger sites, or where you work with public sector organisations and need a more formal assessment, it is sensible to arrange a proper manual audit. Automated checks are valuable, but an experienced review can assess the journey a real visitor takes through the site.

FAQs

Are website accessibility tools free?

Many useful tools have free versions, including WAVE and Lighthouse. Free checks are usually enough to identify common issues on a small business website. Paid tools can make sense for larger websites, frequent testing or teams managing lots of content.

Can an accessibility plugin make my WordPress website compliant?

No plugin can guarantee that. It can highlight and sometimes help correct content issues, but it cannot fully assess your theme, forms, navigation, PDFs or the experience of using the site with assistive technology.

What is the easiest accessibility issue to fix first?

Start with colour contrast, image alternative text, meaningful link text and proper headings. These are common, practical improvements that often benefit both accessibility and day-to-day usability.

Do accessibility improvements help SEO?

They can help indirectly. Search engines and visitors both benefit from clear page structure, descriptive links, useful image text and a site that is easy to navigate. Accessibility is not a magic ranking button, but it supports a better overall website.

How often should I test my website?

Check key pages after a redesign, theme change or major plugin update. For an active WordPress site, a quick monthly check and a more thorough review when you add new templates or forms is a sensible rhythm.

Do I need to test every page on my site?

Not necessarily at first. Test the most important templates and visitor journeys, then fix sitewide issues. Once those foundations are right, review older pages as they are updated rather than creating an enormous job list you will never want to open again.

A more accessible website is rarely created by one clever tool or a dramatic overhaul. It comes from making better decisions each time you publish a page, add a form or change a design. Start with the pages that bring in enquiries, fix the obvious friction, and keep going. Your visitors should not need to work hard just to give you their business.
