An accessible website is fully compatible with assistive technology devices including screen readers, braille displays, screen magnifiers, and more. Accessible websites work seamlessly with these technologies to ensure that individuals with disabilities have full access to information, goods and services on the web.

Inaccessible websites can be difficult or impossible for assistive technology users to access, and can expose your business to legal liability in the form of an ADA lawsuit.

What is the trend towards Website Accessibility about?

Law firms are increasingly filing class action suits on behalf of disabled individuals throughout the United States who use the Internet to facilitate their access to goods and services. These individuals have disabilities that include: blindness and low vision, deafness and hearing loss, learning disabilities, cognitive limitations, mobility impairments, speech disabilities, photosensitivity and combinations of these.

What standards are available for website accessibility assessment?

The World Wide Web Consortium (W3C) has created the Web Content Accessibility Guidelines (WCAG 2.0) to help website owners and developers meet the challenges of developing accessible web content for assistive technology users. Learn more about the WCAG: https://www.w3.org/TR/WCAG20/ .

The Web Content Accessibility Guidelines are based on four basic principles of accessibility. These require websites to be perceivable, operable, understandable and robust:





Common Barriers to Website Accessibility

Properly designed websites and web tools can be used by people with disabilities. However, currently many sites and tools are developed with accessibility barriers that make it difficult or impossible for some people to use them. Below are just a few examples:

  • Images missing alternate text – alternate text provides supplemental information about the context and content of images for blind users.
  • Website navigation systems not usable with a keyboard only – screen reader users and people with motor impairments cannot use a mouse to navigate webpages. The WCAG requires that web page navigation systems be usable with a mouse only.
  • Videos missing captions – synchronized captions are a text alternative for the audio track in a video or multimedia presentation. Captions allow deaf and hearing-impaired people to access the audio portion of video content.
  • Webpages missing semantic structure – headings, lists, and other webpage markup are essential to help assistive technology users understand the structure of webpages.

One or more of these accessibility barriers could make your site difficult or impossible to use for people with disabilities. By removing barriers to accessibility, you can open your website to a much wider audience, attract new customers, and reduce exposure to legal liability.
