How to Test Your Website's Accessibility and Improve User Experience

By Al Romano

As the world becomes increasingly digital, the importance of website accessibility cannot be overstated. It's essential to ensure that all users, regardless of their abilities, can easily access and use your website, irrespective of their abilities. Not only is it the right thing to do, but it's also required by law in many countries. However, testing website accessibility can seem daunting, especially if you're unfamiliar with the guidelines and tools available. This article explores essential steps to test your website's accessibility and improve user experience. From understanding the WCAG guidelines to using automated tools and manual testing, you'll learn how to identify accessibility issues and fix them. So, whether you're a website owner, developer, or digital marketer, this guide is for you. Let's get started and ensure everyone can access your website without barriers.

Why website accessibility matters

Website accessibility is crucial for several reasons. First, it ensures that your website is inclusive and accessible to all users, regardless of their abilities. This means that people with disabilities, such as visual, auditory, or physical impairments, can easily access your website. Second, it's required by law in many countries. In the United States, for example, websites must comply with the Americans with Disabilities Act (ADA), which prohibits discrimination against people with disabilities. Failure to comply with these regulations can result in legal action and hefty fines. Finally, website accessibility improves user experience and increases engagement, conversions, and customer loyalty.

Understanding web accessibility guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG) are guidelines developed by the World Wide Web Consortium (W3C) to ensure that websites are accessible to all users. The procedures are organized into three levels of conformance: A, AA, and AAA, with AAA being the highest level of accessibility.

The guidelines cover several areas, including perceivable, operable, understandable, and robust. Perceivable means that the content must be presented so that users can perceive it, regardless of their abilities. Operable means that users must be able to operate the website's interface, including navigation and forms. Understandable means that the content must be presented so users can understand it. Robust implies the website's content must be compatible with various user agents, such as different browsers and assistive technologies.

Tools to test website accessibility

Several automated tools can help you test your website's accessibility. These tools analyze your website's code and highlight accessibility issues, such as missing alt text, low contrast, and keyboard navigation issues. Some popular tools include:

  • WAVE: a free online tool that provides visual feedback on your website's accessibility issues.

  • Funkify: a free browser extension that identifies accessibility issues and provides in-depth guidance on remediating them.

  • aXe: a free browser extension that identifies accessibility issues and provides advice on how to fix them.

  • Lighthouse: a tool built into Google Chrome that audits your website's accessibility, performance, and more.

While automated tools can identify many accessibility issues, they're not perfect. Some problems require manual testing to remember, and computerized tools can't always detect context-specific issues. Therefore, it's essential to use a combination of automated and manual testing to ensure your website is accessible to all users.

Testing website accessibility manually

Manual testing involves using assistive technologies like screen readers and keyboard-only navigation to test your website's accessibility. This type of testing can be time-consuming, but it's essential to ensure your website is accessible to users with disabilities.

To perform manual testing, you'll need to install and use assistive technologies, such as:

  • Screen readers: software that reads aloud the content on the screen for users who are blind or have low vision.

  • Keyboard-only navigation: testing the website's navigation using only the keyboard, without the mouse.

  • Voice recognition software: allows users to navigate the website and input text using voice commands.

Using these tools, you can identify accessibility issues that automated devices can't detect, such as missing landmarks, incorrect headings, and confusing form labels.

Common website accessibility issues

Several common website accessibility issues can make it difficult or impossible for users with disabilities to access your website. By understanding these issues, you can identify and fix them to improve your website's accessibility. Some common accessibility issues include:

  • Missing alt text: Images without alternative text can be challenging or impossible for visually impaired users to understand.

  • Low contrast: Low-contrast text and images can be difficult for low-vision users.

  • Inaccessible forms: Forms that are difficult to navigate or use can be challenging for users with disabilities.

  • Non-descriptive links: Links that don't describe where they lead can confuse users with disabilities.

  • Poor website structure: Websites with poor structure can be challenging to navigate for users with disabilities.

By addressing these common issues, you can ensure that your website is accessible to all users.

Improving website accessibility

Improving website accessibility requires a combination of automated and manual testing, as well as design and development changes. Some tips for improving website accessibility include:

  • Use descriptive alt text: Provide alternative text for images that accurately describe the image's content.

  • Increase contrast: Use high-contrast colours to make text and images more accessible to low-vision users.

  • Use semantic markup: Use HTML tags, such as headings and landmarks, to provide structure and meaning to your website's content.

  • Provide captions and transcripts: Provide captions and transcripts for audio and video content to make it accessible to users with hearing impairments.

  • Design for keyboard navigation: Ensure your website's navigation and forms can be used with a keyboard and don't rely on mouse-only interaction.

By implementing these changes, you can improve your website's accessibility and ensure that all users can access and use your website with ease.

Tips for Designing an accessible website

In addition to making design and development changes, designing an accessible website requires a user-centred approach. Some tips for designing an accessible website include:

  • Understand your users: Understand your users' needs and preferences, including those with disabilities.

  • Follow accessibility guidelines: Follow the WCAG guidelines to ensure your website is accessible to all users.

  • Simplify your design: Use simple, clean design principles to make your website more accessible and easily navigate.

  • Provide clear instructions: Provide clear and concise instructions for using your website's features and functionality.

  • Test with users: Test your website's accessibility with users with disabilities to identify issues and receive feedback.

By designing with accessibility in mind and testing your website with users, you can ensure that your website is user-friendly and accessible to all users.

User testing for accessibility

User testing for accessibility involves testing your website with users with disabilities to identify accessibility issues and receive feedback. This type of testing can help you understand your users' needs and preferences and ensure that your website is accessible to all users.

To perform user testing for accessibility, you'll need to recruit users with disabilities and provide them with specific tasks to complete on your website. You'll also need to provide assistive technologies, such as screen readers, for users who need them. By observing users as they navigate your website, you can identify accessibility issues and receive feedback on how to improve your website's accessibility.

Conclusion

Website accessibility is essential for ensuring that all users can easily access and use your website, regardless of their abilities. By understanding the WCAG guidelines, using automated and manual testing tools, and making design and development changes, you can improve your website's accessibility and user experience. Remember to design with accessibility in mind, test with users, and continuously improve your website's accessibility to ensure that all users can access and use your website without barriers.
