Make Your Website Accessible with Accessibility Checker

Equalize Digital’s Accessibility Checker provides accessibility error and warning notifications right on your post and/or page edit screen.

Accessibility Checker automatically scans your content each time you save a draft or hit publish, giving you real-time feedback on your post’s or page’s accessibility. Receive a visual overview of how your content stacks up against more than 40 different accessibility checks created to meet Web Content Accessibility Guidelines (WCAG) 2.1 success criteria.

For each error or warning flagged, Accessibility Checker lists the code that triggered the error or warning. Each item is identified as an error or warning depending upon its severity, so that you can prioritize your fixes. Thorough documentation is available to guide you on how to fix accessibility problems on your website and personalized accessibility remediation assistance and accessibility consulting is available if desired.

Ensure Ongoing ADA, Section 508, AODA, & WCAG Compliance

For already accessible websites, Accessibility Checker is an excellent tool for ensuring ongoing compliance and accessibility.

The in-page tests help content managers and contributors confirm they have entered their content in an accessible manner. There’s no need to be an accessibility expert or memorize long lists of WCAG success criteria – Accessibility Checker provides an easy to understand accessibility checklist and reading level checks so that you can ensure you’re not adding accessibility problems as new content is added.

Content area scans are visible on each post’s or page’s edit screen as you type – no need to go elsewhere on your site to view results or visit a third-party website. These scans allow your team to create accessibile websites from the start, reducing the need for costly retroactive remediation.

A Vital Part of Your WordPress Accessibility Strategy

Accessibility Checker is the best automated tool to run along with your manual accessibility tests. It’s perfect for small business websites, large enterprise organizations, and everything in between. Whether you’re running a small brochure website, an eCommerce store with thousands of products, or a multi-site network for a university, Accessibility Checker is the right tool for your website.

Installing Accessibility Checker Within WordPress

  1. Visit the plugins page within your dashboard and select ‘Add New’.
  2. Search for ‘Accessibility Checker’;
  3. On the Accessibility Checker plugin, click or activate the ‘Install’ button.
  4. Activate Accessibility Checker from your Plugins page.
  5. Follow the ‘after activation’ steps listed below.

Installing Accessibility Checker Manually

1.Upload the unzipped ‘accessibility-checker’ folder to the /wp-content/plugins/ directory on your website via FTP.
2. Activate Accessibility Checker from your Plugins page.
3. Follow the ‘after activation’ steps listed below.

After Activation

After activating the plugin, go to the Accessibility Checker settings page in your WordPress admin (found at ‘/wp-admin/admin.php?page=accessibility_checker_settings’) to configure the plugin settings.

Current settings in the free plugin include:
* Ability to control when the plugin prompts for a Simplified Summary.

Does this plugin make my website accessible?

No. Despite what other plugins, integrations, or overlay products might tell you, there is NO way for any automated tool or plugin to ensure your website is fully accessible. True accessibility can only be achieved through a combination of automated scans and manual review, and if you read the ‘fine print’ for any of the accessibility overlays or plugins on the market, you’ll see that they do not guarantee your website will be accessible.

Accessibility Checker does not make your website accessible, but it is a valuable tool to help you make your website accessible, the right way.

Is this an accessibility overlay or tool bar like AccessiBe, Userway, AudioEye, etc.?

No. Accessibility Checker is a testing tool that scans for problems and presents reports in the admin dashboard. It does not “fix” problems or add any overlays, toolbars, or widgets to the front end of your website. It will not use JavaScript to modify how screen reader and other assistive technology users are able to engage with your website.

Accessibility Checker is the kind of accessibility tool that accessibility consultants and people with disability support – one that helps you identify issues so that you can make your website accessible the right way.

Does Accessibility Checker scan all of my content?

Accessibility Checker Free scans blog posts and pages, including the header, content area, sidebar, and footer on those pages. There is no limit to the number of pages or posts that you can scan with Accessibility Checker or the number of times any one page or post can be scanned. So, if your website only contains standard posts and pages, then YES, Accessibility Checker will scan all of your content. If you have custom post types (such as a portfolio, team member pages, or WooCommerce products), the free version of the plugin will not scan these posts.

For bulk full-site scanning or to check custom post types for accessibility, please upgrade to Accessibility Checker Pro.

How do I know how to fix accessibility problems on my website?

Every error and warning in Accessibility Checker has an ‘i’ icon to the right of the error or warning name on the details tab. If you click these ‘i’ icons, you’ll be directed to a help article that clearly explains what the error or warning is, what its impact on accessibility is, and how to fix or resolve it. Generally, these help articles will provide sufficient information to point you in the right direction, but if you still have questions, open a support ticket on WordPress.org and we’ll do our best to help you.

Can you help me fix accessibility problems on my website?

Yes! If you need need accessibility fixes custom coded for your site, we offer website accessibility remediation to help bring your current site into compliance. Learn more about Website Accessibility Remediation

What if there are accessibility errors in my theme or a plugin that I cannot fix?

If Accessibility Checker is identifying errors in your theme or a plugin and you’re not sure how to fix them, the best bet is to reach out to the theme or plugin developer for assistance. If that does not work, we may be able to help. There is more guidance about how to handle problems in your theme or plugins at:
* What to do if a Plugin You’re Using has Accessibility Errors
* What to do if There are Accessibility Errors in Your Theme

Will this slow down my website?

Accessibility Checker does not load anything on the front end of your website so it has zero speed impact for your website visitors.

Do I have to connect to any third-party APIs?

No, Accessibility Checker runs completely on your server and does not require you to connect to any external APIs or services for scans. This can save you thousands of dollars per year in accessibility scanning fees and is privacy-focused, ensuring that your website data stays completely under your control.

I love the free version of this plugin and after using it for a while upgrading to the paid version was a “no-brainer”. Whilst the paid version does much more, the free version of the plugin is an excellent place to start and get used to how the plugin works and how to action/interpret the results. Brilliant work from a brilliant team with excellent support and helpful articles/tutorials to guide you along the way.

There are a number of accessibility checker plugins that work like this one does. I tried this one and I liked it, but ended up going with a different choice. Pros: accurate and meaningful checks with explanations. very clean and easy to read summary. Cons: apparently does not check content until after a post is saved. includes issues in headers and footers, and other plugins (which ultimately are important things to check but not necessarily something the editor of a post or page has any control over).

I have learned so much about accessibility from this plugin and making my website user-friendly for all. I try and use open-source resources as much as possible and I appreciate that there is a free version of the Accessibility Checker plugin. It has given me the confidence to help and educate others about accessibility.

FIrst off, I am not a fan of the phrase “Game Changer,” but this plugin is… a game changer!As someone who is now committed to ensuring our (mine and our clients) websites are accessible to all users, the Accessibility Checker plugin for has been a standout addition to our toolkit, and it’s truly deserving of a five-star review. The plugin’s thoroughness is impressive; it doesn’t just skim the surface but goes deep into the website, checking each element against established accessibility standards. What sets it apart is how detailed the analysis is. It identifies every potential accessibility violation, which has been an eye-opener for our team (nothing like seeing a site hF 8,357 VIOLATIONS to wake you up!)The detailed reports include specific violations and, importantly, offer clear, suggestions on how to correct these issues. This feature is invaluable as it not only points out what is wrong but also shows you on how to fix it (by the way, fixing one issue can easily correct 100s of issues in one shot!) I’ve decided that this plugin will be used for testing all our clients’ websites. If you want to make sure your site “passes all the test for accessibility” try this out. And if you really want to make your life easier as you do this, upgrade for the Pro version – it will save you a ton of time.
