Web accessibility has become an increasingly important consideration in recent years, as businesses recognize the significant benefits of providing a user-friendly and inclusive online experience for all visitors. Ensuring that your website uses universal design principles is not only a moral and ethical responsibility, but it can also help to avoid potential legal ramifications.
Designing for accessibility means creating a website that is usable by a diverse array of users, including those with disabilities, such as visual, auditory, cognitive and motor impairments. It may seem like a daunting task, but adopting a mindset of universal design and following guidelines such as Web Content Accessibility Guidelines (WCAG) can make the process much easier.
In this article, we will explore key concepts and strategies to help make your website inclusive and accessible to all users.
Understanding the Needs of Users with Disabilities
There are hundreds of millions of visually impaired people worldwide, and this number is expected to rise. Nearly half a billion have disabling hearing loss. A significant number of internet users may also have cognitive or motor impairments that can make navigating websites challenging.
The first step in designing an accessible website is to understand the needs of users with disabilities, as well as the various assistant technologies that they may use to access the internet. For example, visually impaired users may rely on screen readers (software that reads the text content of a website out loud), while deaf or hard-of-hearing individuals may utilize closed captioning or transcripts.
Principles of Universal Design
Universal design is a concept that advocates for designing products, services, and environments that are usable by all people, regardless of their abilities or disabilities. The idea is to create one well-designed solution that meets the needs of the broadest possible audience, rather than designing multiple solutions for different types of users.
Here are a few steps to help you apply the principles of universal design to your website:
1. Structure and Layout: Establish a consistent and predictable layout throughout your site to make it easy for users to navigate, regardless of their abilities. Use headings and subheadings to create a logical hierarchy of information, and ensure that your content is presented in a clear and meaningful way. (It also helps your SEO.

2. Text Formatting: Always use clear, easy-to-read fonts and font sizes, with sufficient contrast between the text and background colors to increase readability. Ensure that you provide alternative text (alt text) for images and other non-text content, so that screen reader users can get the appropriate information.
3. Keyboard Navigation: Make sure that all elements of your website are accessible by keyboard alone. Many users with motor impairments cannot use a mouse or touchscreen, relying solely on keyboards. To accomplish this, ensure that all important elements of your website – such as links, buttons, and form fields – can be accessed and activated using just keystrokes.
4. Multimedia: Provide accompanying text transcripts for podcasts and videos, and include closed captions and descriptive audio for video content. This will ensure that visually impaired and deaf or hard-of-hearing users can access your multimedia content. (This also helps with your SEO efforts. See Optimize Videos for SEO: Why and How.)
Implementing Accessibility Features and Tools
There are a variety of tools and features available that can help you make your website more accessible. Here are some suggestions:
1. Alternative Text: As mentioned earlier, always provide alternative text for images, infographics, and other non-text content. Alternative text should be descriptive and informative, providing context and meaning for users who are unable to see the visual content.
2. ARIA Attributes: Accessible Rich Internet Applications (ARIA) is a set of attributes that can be added to HTML elements to provide additional information for assistive technologies. For example, you can use ARIA landmarks to indicate the role of a particular element (such as a navigation menu or main content area), making it easier for screen reader users to understand the structure of your site.
3. Accessible Form Fields: Ensure that your forms are accessible by including descriptive labels and instructions for each field. Use proper coding techniques, such as using the “label” element in HTML to associate labels with form fields, which can help users with screen readers understand the purpose of each.
4. Skip Navigation Links: Include “skip to main content” or “skip navigation” links at the beginning of your site, allowing keyboard users, as well as screen reader users or those with motor impairments to bypass lengthy menus and get straight to the primary content.
Testing Your Website for Accessibility Compliance
After implementing these features, it’s important that you test your site to ensure compliance with accessibility standards, such as the Web Content Accessibility Guidelines (WCAG) mentioned above.
There are several tools available online that can help you evaluate your website:
1. Automated Testing Tools: Tools like WAVE, AChecker, and axe can help you identify issues, such as missing alt text, insufficient contrast between text and background, and missing labels for form fields.
2. Manual Testing: It’s important to conduct some manual testing, as automated tools can’t catch everything. Manual testing techniques include navigating your website using only the keyboard, testing with various screen readers, and ensuring that all multimedia content is accessible via transcripts, captions, and descriptive audio.
3. Expert Evaluations: If you’re unsure about your site’s accessibility compliance, consider hiring an accessibility expert to assess your website and provide recommendations for improvement.
Designing for accessibility is an ongoing process, and it requires a commitment to continuous improvement. By understanding the needs of users with disabilities, applying the principles of universal design, and implementing accessibility features and tools, you can create a more inclusive online experience for everyone.
In embracing accessibility, not only do you broaden your potential audience, but you also demonstrate a commitment to social responsibility, ultimately enhancing your brand reputation.
