Tools for Diagnosing Website Accessibility Issues

Blog Home

There are lots of tools and resources for diagnosing website accessibility issues — we run you through which ones can help on your site.

WAVE

Wave is one of the most popular web accessibility tools, and with good reason. It provides robust output on individual pages on your website, has both a standalone tool and a variety of plugins for different browsers, and is free. 

We've found that the WAVE Chrome extension is the most useful. You can install it in your browser, and then it just takes one click to diagnose any page you're on and get both a text and graphic report of what's going wrong. The only downside to WAVE is that you have to test each page individually and can't get a full site report.

As with all accessibility tools — or any automated tool used to diagnose anything on a website — it's important to keep in mind that you're trying to make your site accessible, not trying to make your site look good to WAVE. WAVE will flag a ton of things, but not all of them will need to be addressed on your site, even if you're trying to meet strict accessibility standards. So instead use it as a tool to figure out what you want to address, and feel free to ignore anything that's not relevant to your goals.

WCAG Guidelines

The official WCAG guidelines can be a bit much to take in all at once, but they can be invaluable in figuring out how to meet specific requirements flagged by an accessibility checker. For example, some accessibility checkers will flag sites for standard 2.4.5, which requires sites to have multiple ways to access content. Looking at the actual standard, though, you'll see that there are multiple ways to meet the standard, and if you have site navigation and site search, you're probably all set. The WCAG guidelines might not be the first thing you reach for to diagnose your site, but they're indispensable for addressing specific issues.

SiteSort

SiteSort is downloadable software that will perform an accessibility check on your entire website at once — which is its big advantage over other tools. Running a check on your entire site can help you see common accessibility issues that you might be able to fix in bulk, and it also helps you notice issues that you might miss checking individual pages. SiteSort can also check for basic SEO best practices compliance and other site issues, like broken links.

The downside to SiteSort is that, after a free trial, software licenses start at $149. That's not super expensive, as far as software goes, but it can be a deterrent when free tools offer much of the same functionality. But if you're looking for a comprehensive solution to check your entire site, generate accessibility and SEO reports, and monitor your site for issues, SiteSort can be worth the investment.

Google Accessibility Developer Tools

Google provides a Chrome accessibility plugin that adds accessibility functions to its existing Developer Tools. It offers most of the same functions as the WAVE plugin, with on-page diagnosis of potential accessibility issues. The big difference between this and WAVE is that the output is tied to Chrome's developer tools — so if you're a developer who's addressing accessibility, the Chrome tool will seem like a natural extension of the work you already do with accessibility. But for non-developers, it might be slightly confusing to figure out exactly how to access the Google accessibility plugin. 

Screen Readers

Screen readers — the actual assistive devices that will process your website and read its content— are one of the least-used accessibility tools, but can be one of the most useful. Nothing will highlight accessibility issues with your site like trying to use it yourself with a screen reader. The downside, of course, is that screen readers are expensive, and it can be a large time investment to get it set up. But if you want to go all-in on accessibility, a screen reader can help you make your site a great experience for users on assistive devices.
