Accessibility audit on a website

What is a web accessibility audit?

An accessibility audit is a thorough, professional evaluation of how well your website and other digital properties meet the needs of people with disabilities, conform with the Web Content Accessibility Guidelines (WCAG) technical standards, and comply with the ADA. This isn’t something anyone can know just by glancing at your website or spending a few minutes using your app. When an audit is carried out properly, every component is examined and tested by experts, so that when it’s complete, you can be confident that the web accessibility audit report has identified any and all barriers.

A website, app, or document is considered accessible if it can be perceived, understood, navigated and interacted with by everyone. It doesn’t discriminate, with sections of information that can only be engaged by someone using a mouse, or certain app features that can only be used by a sighted individual. Rather, it is barrier-free for everyone. That includes people who are using assistive technologies (AT), such as a screen reader.

Why sign up for an accessibility audit?

The real question is: why make a commitment to removing barriers from your website?

From complying with legal and regulatory mandates to supporting internal DEI (Diversity, Equity, Inclusion) initiatives, organizations have numerous reasons to actively remove web accessibility barriers and optimize digital experiences for everyone.

Digital accessibility is the law

Various global regulations mandate digital accessibility. When it comes to compliance with applicable laws, there are multiple factors that come into play, like where your organization is located, who you’re selling to, or the size of your business. Some examples of accessibility legislation are:

From 2017–2020, plaintiffs claiming discrimination filed more than 10,000 ADA web-related lawsuits in the U.S., and that number grew steadily in 2021. Additionally, each year hundreds of thousands of legal demand letters are sent that don’t result in lawsuits, but can result in costly settlements and fines, accompanied by legal fees.  

Bottom Line: An audit (or more specifically, a web accessibility audit report) will help you understand the scope of your digital assets’ accessibility and whether you’re complying with various legal mandates.

Digital accessibility is good for business 

When seeking a web accessibility audit to evaluate their state of accessibility, businesses should keep in mind the benefits of digital inclusivion to a brand’s bottom line and reputation.  

With people with disabilities in the U.S. representing up to a quarter of the adult population, the market opportunity is too large for any business to ignore. Worldwide, the number of people with disabilities is estimated to be 1.85 billion, and translates to a global community controlling over $13 trillion in annual disposable income

Further, consumers are loyal to brands that share their same values. Demonstrating a commitment to inclusion by embracing digital accessibility positions your brand positively in the eyes of the consumer. 

Catering to people with disabilities requires an inclusive approach to your websites and communications. With the findings from a  web accessibility audit report, you’ll be on your way to reaching, and better serving, this market.

What standards should an accessibility audit test against?

The most universally-recognized standard used in testing for accessibility is the Web Content Accessibility Guidelines (WCAG). This standard was established with global input from members of the World Wide Web Consortium, or W3C, and provides a single, common, and regularly updated global guide for digital accessibility. 

WCAG itself is not a piece of legislation but it is referenced in numerous pieces of legislation around the world, and has become the international standard for web accessibility. For example, the Department of Justice has recently cited WCAG 2.1 AA as its benchmark for accessibility. And Section 508, and the AODA evaluate accessibility against WCAG 2.0 Level A and AA success criteria. Legal compliance with most global regulations requires conformance with WCAG standards.

WCAG has evolved several times since its conception. Each version of WCAG contains testable success criteria—or guidelines to follow—that fall under three conformance levels: A, AA, and AAA. To learn more about what’s new in WCAG, read our summary and checklist for WCAG 2.2 AA conformance. 

What’s included in the scope of an accessibility audit?

An accessibility audit should test multiple pages and be conducted using a combination of:

  • Assistive technologies, such as screen readers
  • Automated tools
  • Browsers
  • Accessibility plugins
  • Devices (desktops, tablets, and smartphones)

What does an accessibility audit process entail?

Three approaches to accessibility testing are involved in producing a web accessibility audit report, and they should be used together to evaluate and support conformance with web accessibility.

Automated testing

An automated testing tool is an important component of a digital accessibility audit. It enables you to scan and report on your digital asset’s accessibility issues. A web accessibility audit  report will flag certain accessibility barriers and their severity, and often includes an overall accessibility health score. Your score can serve as a baseline as you track your accessibility improvements over time. 

Automated testing can test for about 30 percent of WCAG criteria. It reports an automatic “pass” or “fail” as to whether a certain condition is met on a web page, such as a set standard for color contrast, or the presence of alternative text (“alt-text”) to describe an image. Automated testing is not capable of finding every barrier, but often it’s a helpful tool, especially when it comes to repetitive tasks. Some examples of tools used during automated testing include color contrast checkers, ATs, browsers, and device operating systems in various combinations and environments (such as web or mobile).

Manual testing 

Manual testing builds upon automated scanning, testing for the 70 percent of WCAG criteria that automated tests can’t. Additionally, because automated tests tend to produce false positives where no barriers exist, those must be confirmed by a human consultant. Judgment is also required to further evaluate certain features. For instance, an automated test can tell you that alt text has been included for an image, but it can’t tell you whether the text accurately conveys what’s in the image or explains what the image is for. It also can’t tell you whether the tabbing order on the page is in a sequence that makes sense. It takes a person to do that.

Examples of activities performed during the manual assessment include:

  • Using a screen reader to evaluate the display of information
  • Using keyboard tabs to navigate through a page
  • Evaluating the color contrast of a web page

Functional testing

Functional testing is also critical because a website that appears to be accessible might be impossible to use for some people with disabilities, and sometimes the only way to discover this is by actually trying to use it. For example, can forms be submitted or products selected by individuals who type slowly, or who use a keyboard or voice commands in place of a computer mouse? Functional testing, which typically involves users with disabilities and/or users of assistive technologies, is used to confirm that ATs such as screen readers can interact properly with the website and its content. Also, it provides HTML and CSS best practices to avoid attributes or values which cause compatibility issues with some ATs.

Technologies that may be used in assessing a website’s accessibility

In completing an accessibility audit, different techniques and assistive technology software and tools can be used, depending on several factors, including:

  • Ease of access for users with disabilities, i.e., free technologies like NVDA and VoiceOver
  • Most widely used browser according to WebAIM metrics i.e., Chrome
  • Impact on system performance when the AT integrates with the operating system i.e., if the AT may slow down system performance for the users once installed 

Test Screens and Critical User Paths

In auditing a site, the test plan should include a range of unique page types, content, and functionality, designed to be representative of the website or mobile app and its core user-flows.

The downside of DIY

It may be tempting to do your own accessibility audit—especially when you hear about tools like automated checkers, and find out that the experts use those, too. The difference, of course, is that experts know what to do with the findings. They know how to find issues that automation and untrained staff can’t,  how to fix the errors, and when to disregard certain errors as false positives.

And they certainly don’t rely on automated testing alone. The manual and functional testing described above are indispensable components of a complete, professional accessibility audit that you can rely on. If your own DIY audit skips these steps, the testing is incomplete and may be putting your organization at legal risk for non-compliance.

What to do with your web accessibility audit report

When you hire qualified experts to conduct an accessibility audit of your digital properties, you can be assured that the audit will be thorough, and that all barriers will be identified. But, it’s important to recognize that a web accessibility audit report is just the first step in your accessibility journey. With your web accessibility audit report in hand, you can then move on to the next stages in the process of making and keeping your technologies accessible to everyone.

A well-conducted accessibility audit should yield a web accessibility audit report that can set a baseline for your organization’s ongoing accessibility program— the work of establishing a compliant, accessible, and inclusive websiteand, then, continually maintaining that standard of accessibility as technology, content, and laws change. Finding an accessibility partner, with experts who can test, validate, support, train, and enable your team to ensure sustainable accessibility compliance, and provide legal guidance, is key.
