Make Your Website Accessible with Accessibility Checker

Accessibility Checker by Equalize Digital provides easy to understand 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. Each item is identified as an error or warning depending upon its severity, so that you can prioritize your fixes. For each error or warning flagged, Accessibility Checker lists the code that triggered the error or warning. Thorough documentation is available to guide you on how to fix accessibility problems on your website.

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 test helps content managers and contributors confirm that they have entered their content in an accessible manner. No need to be an accessibility expert or memorize long lists of WCAG success criteria – Accessibility Checker provides an easy to understand accessibility checklist. 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.

Getting started with Accessibility Checker is as easy as installing and activating the plugin, then configuring a few basic settings.

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.
* Ability to set the position of the Simplified Summary, if using, above or below content or manually with a function in a page template.
* Ability to turn off Accessibility Checker for posts or pages as desired.
* Set a username and password to allow scanning functionality on password-protected sites.


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.

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 a full-site scan 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 and we’ll do our best to help you.

If you need detailed consultation or custom coding assistance, we offer Priority Support Packages. These packages include email, phone, and Zoom support and are ideal for individuals or teams who need more hands-on assistance in resolving accessibility problems on their website.

This plugin makes it so easy to zero in on the potential issues on EVERY page on my site. They care about accessibility (and security), and it shows. It cuts back on so much of the manual work of reviewing every single page by hand, so that when it is time to run a manual check, it goes so smoothly. The fact that it supports the major page builders is huge, and if something does come up that doesn't need to be fixed, I can just ignore it remove it from the list. I absolutely LOVE the information that's given for each page and post. It's so helpful. And I feel confident that if something does change with accessibility, this plugin will continue to keep up with it.

This is a solid plugin for testing for Accessibility issues on a website. It is one of the three tools I use for testing each page I build. What is helpful is that is actually on the website for the client to see. It is also useful for training my VA on accessibility as it points out the issues that need to be addressed. I use the Pro version but for those getting started building Accessible sites, this is a great tool. Accessibility Checker combined with AXE Chrome extension and webaim tools will get you the information you need to build pages that can be used by all.

I'm new to implementing accessibility to my projects and this plugin is such a gem that I install it on every website I make, not just during development but also for monitoring and making sure new contents are accessible. Highly recommended to have this on your projects to make your websites much, much better.

(Review updated) I've been using Accessibility Checker for some weeks now, weeding out issues in my blog posts, communication with theme developers for theme wide fixes and comparing the reports of AC with other accessibility checks, and my experience is very positive. Cons: - The plugins struggles with a few CSS declarations, probably custom properties (variables). That can make it difficult for the plugin to identify colours, which might trigger false contrast errors. - The Summary tab in the block editor (Gutenberg) shows the test results in HUGE coloured blocks, pushing other panels unnecessarily down the page. It contains 6 numbers while still taking up 50% of the screen. Aesthetics are personal, and you can't please everyone, I know 🙂 Developer is considering a slimmer design though. Pros: - "Removing a warning or error rule is not advised, however, if you have a specific use case that warrants removing a rule or group of rules, you can do so" ... with a code snippet from the documentation. - Performs 40 FORTY! accessibility checks. Your site might still not be perfect, but passing these tests is a great baseline. - Tests right within the editor, which is a huge plus. Makes it so much easier to address issues on the fly. - The most amazing part of Accessibility Checker, is in my opinion the in-depth explanations of issues, why they are an issue, and actual real world recommendations on how to fix them. Such good advice is rarely seen in free tools like this. So in conclusion, Accessibility Checker is another great addition to your a11y toolkit - just don't let those possibly "false positives" freak you out. Highly recommended.

So nice to have accessibility guidance from within wp-admin and not having to run your site through an external tool. Looking forward to seeing this plugin develop!

Accessibility is a priority for me and our team at Agent Engine. While I thought we had taken good steps toward being fully accessible, it was not enough. Thankfully, we did a full site scan using Accessibility Checker Pro and found several errors/flags that we were able to remedy. Not only is our website more accessible, I learned a lot about by going through this process. I highly recommend this plugin for anyone who has a website—from solo creator to small business.
