A business website should be easy to navigate, understand, and use for as many people as possible. However, some websites create unnecessary barriers through low-contrast text, confusing navigation, inaccessible forms, or images without meaningful descriptions.
Website accessibility focuses on making digital experiences more usable for people with different abilities, including people who use screen readers, keyboard navigation, captions, or other assistive technologies.
For businesses, accessible web design is an important part of creating a professional, user-friendly digital presence. It can improve usability, support customer engagement, and help more visitors access the information they need.
1. What Is Website Accessibility?
Website accessibility means designing and developing websites so people with disabilities can perceive, understand, navigate, and interact with online content.
The Web Content Accessibility Guidelines (WCAG), developed by the World Wide Web Consortium (W3C), provide an internationally recognized framework for improving accessibility.
WCAG organizes its guidance around four principles: content should be perceivable, operable, understandable, and robust. These principles cover everything from readable text and keyboard navigation to compatibility with assistive technologies. (W3C WCAG Overview)
2. Improve Readability and Color Contrast
Text should be easy to read across different devices and viewing conditions.
Businesses can improve readability by using appropriate font sizes, clear typography, sufficient spacing, and strong contrast between text and backgrounds.
Avoid relying on color alone to communicate important information. For example, a form should not indicate an error only by turning a field red; it should also provide a clear message explaining the problem.
These improvements can make websites easier to use for visitors with low vision, color-vision deficiencies, and other accessibility needs.
3. Make Navigation Keyboard-Friendly
Not everyone navigates websites using a mouse or touchscreen.
Some users rely on a keyboard or assistive technology to move between links, buttons, menus, and form fields.
Test your website by navigating it using only the keyboard. Make sure users can identify which element is selected, access important functions, and move through interactive components without becoming trapped.
Consistent menus, descriptive link text, and logical page structure can also make navigation easier.
4. Add Meaningful Alternative Text to Images
Images can communicate important information, but visitors using screen readers may not receive that information unless appropriate text alternatives are provided.
Use descriptive alternative text for meaningful images, diagrams, and graphics.
For example, instead of writing “image123.jpg,” describe the image’s relevant purpose or content.
Decorative images that provide no meaningful information can often use empty alternative text so assistive technologies can skip them.
W3C accessibility guidance explains that text alternatives help communicate the purpose and meaning of non-text content to people using assistive technologies. (W3C Accessibility Principles)
5. Design Accessible Forms and Calls to Action
Contact forms, booking forms, and quote requests are often essential to business websites.
If these elements are difficult to use, visitors may struggle to complete important actions.
Improve form accessibility by providing:
- Clearly associated labels for every input
- Helpful instructions where needed
- Understandable error messages
- Keyboard-accessible controls
- Clear confirmation after successful submission
- Sufficiently large, identifiable buttons
These changes can help visitors complete forms more confidently and reduce avoidable frustration.
6. Make Video and Audio Content Accessible
Video and audio can be valuable tools for explaining services, demonstrating products, and communicating brand messages.
However, important information should not depend entirely on hearing or seeing the media.
Consider providing accurate captions for spoken content, transcripts for audio, and audio descriptions when essential visual information is not conveyed through the soundtrack.
These alternatives make multimedia content more accessible and give visitors additional ways to consume information.
7. Test Accessibility Regularly
Accessibility is not a one-time design task.
Website updates, new plugins, redesigned pages, and added interactive features can introduce new barriers.
A practical review should include:
- Automated accessibility testing
- Keyboard-only navigation
- Image alternative-text checks
- Color-contrast reviews
- Form and error-message testing
- Screen-reader testing where appropriate
- Mobile usability checks
Automated tools can identify many common issues, but they cannot detect every accessibility problem. Manual testing and feedback from people with disabilities provide important additional insight.
The W3C provides guidance and resources for designing, developing, and evaluating accessible websites. (W3C Design and Develop Overview)
8. Connect Accessibility With Your Digital Strategy
Accessibility should be considered alongside website design, SEO, performance, security, and conversion optimization.
A clear page structure, descriptive links, meaningful headings, and useful content can improve the experience for visitors while helping search engines interpret a website’s information. However, accessibility improvements alone do not guarantee higher rankings or increased conversions.
Businesses should also understand that accessibility requirements vary by jurisdiction and organization. A general website review is not a substitute for a legal assessment or a complete conformance evaluation.

Frequently Asked Questions
What is website accessibility?
Website accessibility means designing and developing digital content so people with different abilities can access information and interact with website features.
What are WCAG guidelines?
WCAG stands for Web Content Accessibility Guidelines. These guidelines provide technical criteria for improving web accessibility and are organized around perceivable, operable, understandable, and robust content.
Does website accessibility help SEO?
Some accessibility practices, such as clear headings, descriptive links, and meaningful image text alternatives, can also support content understanding and usability. Accessibility and SEO have overlapping benefits, but they are not the same discipline.
Can automated tools make a website fully accessible?
No. Automated tools can identify many common problems, but manual testing and appropriate user feedback are also important for evaluating accessibility.
How often should a website be checked for accessibility?
Review accessibility during website development, before major launches, and whenever significant content or functionality changes. Periodic testing can help identify problems introduced by ongoing updates.
