The information presented within this guide is aimed at website owners seeking to learn the ropes of web accessibility. Technical elements are described in layman’s terms, and, as a rule, all topics pertaining to the legalities of web accessibility are presented in as simplified a manner as possible. This guide has no legal bearing, and cannot be relied on in the case of litigation.

The digital landscape is always evolving, and with each passing year, the importance of web accessibility becomes more evident. The web is a crucial hub for communication, entertainment, education, and commerce, and it's vitally important to ensure that it is accessible to all users, including those with disabilities

Approximately a quarter of adult Americans live with some form of disability. Too often, this group faces unnecessary barriers when trying to access and navigate the web. It is a moral imperative to eliminate these digital barriers, and we all need to do our part to help create more equitable online environments.

Fortunately, there are a number of powerful tools you can use to ensure that your website and web-based applications can be accessed by members of the disability community. Some of these tools perform more specific tasks, such as helping you find the right color contrast between text and its background. Other tools offer more comprehensive solutions and can be relied on to perform more advanced changes to ensure optimal accessibility. 

In this blog, we're going to introduce you to some of the top web accessibility tools available in 2023. We will guide you through their features, show you how they work, and explain how they can help make your website more accessible. 

What is a web accessibility tool?

Web accessibility tools play a crucial role in facilitating access to websites and web-based applications for individuals with disabilities. 

The more comprehensive of these tools work by integrating specific technical and design elements into a website's structure, ensuring it is compatible with assistive technologies such as screen reader tools. They do so by adjusting (or remediating) a website on a code level.

Other web accessibility tools focus on assessment and evaluation. These tools examine a website's level of accessibility by testing its conformance to established web accessibility guidelines, such as the Web Content Accessibility Guidelines (WCAG).

What you need to know about WCAG 

By and large, web accessibility tools aim to help website owners conform to the Web Content Accessibility Guidelines (WCAG). Created by the World Wide Web Consortium (W3C), WCAG is considered the most important global web accessibility standard.

Whether your website is accessible will be determined by its level of conformance to WCAG. 

There are a number of WCAG iterations and each consists of three levels of conformance: Level A, AA, and AAA.

Here's a brief explanation of the differences between them:

How do you conform to WCAG?

Conforming to WCAG entails addressing a number of elements within your website, including, but not limited to:

  • Ensuring compatibility with screen reader technology (e.g., NVDA and JAWS)
  • Allowing for keyboard navigation
  • Tweaking your color contrast to make all elements clearly visible
  • Adding audio transcription to videos
  • Adding alt text to meaningful images
  • Eliminating time limits on web pages
  • Making sure all titles and navigation are clearly labeled 

How can web accessibility tools help you?

They help simplify the web accessibility testing process

Web accessibility tools can play a pivotal role in simplifying and automating the process of web accessibility testing. With the complexity of modern websites and the wide array of potential accessibility issues that can occur, manual testing can be a time-consuming and labor-intensive process.

Web accessibility tools can automate a significant part of this testing process. These tools can quickly scan a website's code, identify potential accessibility issues, and even suggest potential fixes. They can quickly review dynamic content, forms, and hidden elements appearing within a given web page, and provide a comprehensive analysis of their state of accessibility.

They help make the necessary changes within a website to ensure it is accessible

Certain web accessibility solutions don't just spot problems—they help fix them. Once they've identified them, these solutions offer additional, complementary tools that remediate much of the accessibility issues existing within your website’s code. This lessens your dependence on manual intervention, saving you time and money.

They help you comply with with relevant web accessibility laws

There are a number of laws that protect the disability community from being discriminated against when engaging with websites and web-based applications. 

Under the Americans with Disabilities Act (ADA), most businesses’ websites need to be made accessible. To comply with the law, it is widely accepted that websites need to conform to WCAG 2.0 Level AA, at bare minimum. Other laws point specifically to WCAG 2.0 Level AA as the standard websites must conform to in order to achieve compliance. These include Section 508 of the Rehabilitation Act, which applies to government agencies, federally-funded organizations, and service providers to such organizations, and the Accessibility for Ontarians with Disabilities Act (AODA) which applies to most Ontario-registered businesses.

The right tools can help business and website owners assess their websites’ level of conformance with WCAG, and then perform many of the steps that will help bridge the accessibility issues found during the audit.
