Accessible Best Practices for Professionals

In our increasingly digital world, technology plays a pivotal role in nearly every aspect of our lives. But how much thought do we give to ensuring this technology is accessible to everyone, regardless of their abilities? Neglecting accessibility isn’t just unethical, it’s bad for business. Are you truly reaching your full potential if you’re excluding a significant portion of your audience?

Understanding the Importance of Digital Accessibility

Digital accessibility means designing and developing websites, applications, and other technologies so that people with disabilities can use them. This includes people with visual, auditory, motor, and cognitive impairments. It’s about creating an inclusive environment where everyone has equal access to information and services.

Why is this so important? Firstly, it’s a matter of social responsibility. Everyone deserves the opportunity to participate fully in society, and technology should be an enabler, not a barrier. Secondly, there’s a strong business case. According to the World Health Organization, over 1 billion people, or 15% of the world’s population, experience some form of disability. By making your products and services accessible, you’re expanding your potential market and customer base.

Furthermore, many countries have laws and regulations mandating digital accessibility. In the United States, the Americans with Disabilities Act (ADA) has been interpreted to apply to websites and other online platforms. The European Union has the European Accessibility Act, which sets out accessibility requirements for a wide range of products and services. Ignoring these regulations can lead to legal trouble and reputational damage.

Implementing Web Content Accessibility Guidelines (WCAG)

The Web Content Accessibility Guidelines (WCAG) are the internationally recognized standard for web accessibility. Developed by the World Wide Web Consortium (W3C), WCAG provides a set of guidelines for making web content more accessible to people with disabilities.

WCAG is based on four principles, often remembered by the acronym POUR:

1. Perceivable: Information and user interface components must be presentable to users in ways they can perceive. This includes providing text alternatives for non-text content, providing captions and other alternatives for audio and video content, and ensuring that content can be presented in different ways (e.g., simpler layout) without losing information or structure.
2. Operable: User interface components and navigation must be operable. This includes making all functionality available from a keyboard, providing enough time for users to read and use the content, and avoiding content that causes seizures.
3. Understandable: Information and the operation of user interface must be understandable. This includes making text readable and understandable, making content appear and operate in predictable ways, and helping users avoid and correct mistakes.
4. Robust: Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies. This includes ensuring that code is valid and that assistive technologies can access the information they need.

WCAG has three levels of conformance: A, AA, and AAA. Level A is the minimum level of accessibility, while Level AAA is the highest. Most organizations aim for Level AA conformance, as it provides a good balance between accessibility and practicality.

From my experience auditing websites for accessibility, the most common WCAG violations are missing alt text for images, insufficient color contrast, and lack of keyboard navigation. Addressing these issues can significantly improve the accessibility of a website.

Choosing Accessible Technologies and Tools

Selecting the right technologies and tools is crucial for creating accessible products and services. When evaluating software, hardware, or platforms, consider the following:

• Built-in Accessibility Features: Does the technology have built-in accessibility features, such as screen reader compatibility, keyboard navigation, and customizable display settings?
• Accessibility Documentation: Does the vendor provide clear and comprehensive accessibility documentation, including Voluntary Product Accessibility Templates (VPATs)? A VPAT outlines how a product conforms to accessibility standards like Section 508.
• Testing and Validation: Has the technology been tested for accessibility by people with disabilities? Look for independent certifications or endorsements from accessibility organizations.
• Customization and Flexibility: Can the technology be customized to meet the needs of individual users? For example, can users adjust font sizes, colors, and spacing?
• Support for Assistive Technology: Is the technology compatible with common assistive technologies, such as screen readers, screen magnifiers, and voice recognition software?

For example, when choosing a content management system (CMS) for your website, consider options like WordPress, which has a strong focus on accessibility and a wide range of accessible themes and plugins. When selecting online meeting platforms, look for features like live captioning, screen sharing with keyboard navigation, and adjustable volume controls. Zoom, for example, offers many of these features.

Writing Accessible Content

Even with the most accessible technology, content itself can be a barrier if it’s not created with accessibility in mind. Here are some tips for writing accessible content:

1. Use Clear and Simple Language: Avoid jargon, technical terms, and complex sentence structures. Write in plain language that is easy to understand for everyone.
2. Provide Alternative Text for Images: Add descriptive alt text to all images. Alt text should accurately describe the content and function of the image. For decorative images, use null alt text (alt=””) to indicate that the image is not important for understanding the content.
3. Use Proper Heading Structure: Use headings (H1-H6) to organize your content and create a logical structure. Headings should be used in a hierarchical order, with H1 being the main heading and H6 being the least important.
4. Use Lists and Tables Appropriately: Use lists (bulleted or numbered) to present related items in a clear and concise manner. Use tables to present data in a structured format, and ensure that tables have proper headers and captions.
5. Provide Sufficient Color Contrast: Ensure that there is sufficient color contrast between text and background. WCAG recommends a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Use color contrast checkers to verify that your color choices meet these requirements. Many free online tools are available.
6. Use Meaningful Link Text: Use descriptive and meaningful link text that clearly indicates the destination of the link. Avoid generic phrases like “click here” or “read more.”
7. Provide Captions and Transcripts for Audio and Video Content: Add captions to all video content and provide transcripts for all audio content. Captions should be synchronized with the audio and should accurately transcribe the spoken words and other important sounds.
8. Avoid Using Color Alone to Convey Information: Do not rely solely on color to convey important information. People who are colorblind may not be able to distinguish between certain colors.

A study by the Nielsen Norman Group in 2025 found that users with disabilities often struggle with websites that have poor heading structure, unclear link text, and insufficient color contrast. Addressing these issues can significantly improve the user experience for all users, not just those with disabilities.

Testing and Maintaining Accessibility

Accessibility is not a one-time fix; it’s an ongoing process. Regular testing and maintenance are essential to ensure that your products and services remain accessible over time. Here are some steps you can take to test and maintain accessibility:

• Automated Testing: Use automated accessibility testing tools to identify common accessibility issues. These tools can scan your website or application and generate reports on potential violations of WCAG. Examples include WAVE and Axe DevTools.
• Manual Testing: Conduct manual testing to identify accessibility issues that automated tools may miss. This includes testing with screen readers, keyboard navigation, and other assistive technologies.
• User Testing: Involve people with disabilities in your testing process. Get their feedback on the accessibility of your products and services. User testing can provide valuable insights that you may not be able to get from automated or manual testing alone.
• Regular Audits: Conduct regular accessibility audits to identify and address any new accessibility issues that may have arisen. These audits should be conducted by accessibility experts who are familiar with WCAG and other accessibility standards.
• Training and Education: Provide training and education to your employees on accessibility best practices. This will help them create accessible content and technologies from the start.
• Accessibility Statement: Publish an accessibility statement on your website that outlines your commitment to accessibility and provides information on how users can report accessibility issues.
• Stay Up-to-Date: Keep up-to-date with the latest accessibility standards and guidelines. WCAG is regularly updated, so it’s important to stay informed of any changes.

By following these best practices, professionals can create accessible technologies that benefit everyone. Remember that accessibility is not just a legal requirement; it’s a moral imperative. By making your products and services accessible, you’re creating a more inclusive and equitable world for all.

Conclusion

Incorporating accessible technology practices is not just a matter of compliance, but a commitment to inclusivity. By understanding WCAG, choosing accessible tools, writing accessible content, and consistently testing, professionals can create digital experiences that are usable by everyone. Remember, accessibility is an ongoing process, not a one-time task. Start today by auditing your existing content and implementing the strategies outlined above. The result? A wider audience, a stronger brand reputation, and a more equitable digital world.
