What is the WCAG 2.2 AA standard?

WCAG 2.2 AA is a set of guidelines and standards for making web content more accessible to people with disabilities, including those who are blind or have low vision, hearing loss, or mobility impairments. It consists of a set of guidelines that specify how to make web content more perceivable, operable, understandable, and robust. WCAG 2.2 AA also includes success criteria, which are specific requirements that a website must meet in order to be considered accessible.

Benefits of making your website accessible to people with disabilities

Making your website accessible benefits not only people with disabilities, but also your business or organization. By adopting WCAG 2.2 AA, you can:

  • Increase the reach and potential audience of your website
  • Improve the user experience for all visitors
  • Enhance the credibility and professional image of your business or organization
  • Comply with laws and regulations that mandate website accessibility, such as the Americans with Disabilities Act (ADA) in the United States

Legal and ethical considerations of website accessibility

In many countries, there are laws and regulations that require websites to be accessible to people with disabilities. For example, in the United States, the ADA requires that all public accommodations, including websites, be accessible to people with disabilities. Failing to comply with these laws can result in legal action and negative consequences for your business or organization.

In addition to the legal considerations, there are also ethical reasons to make your website accessible. By excluding people with disabilities from accessing your website, you are effectively denying them the same opportunities and information that are available to others.

There is also the economic aspects to consider. Disabled people have jobs and economic power today. Ignoring them with your website design, leaves potential revenue for your competitors to canabilize. Just like in a brick and mortar location, its not realistic to dominate your market if the disabled are excluded.

Potential impact on your business or organization of not adhering to WCAG 2.2 AA

Not adopting WCAG 2.2 AA can have negative consequences for your business or organization. In addition to the potential legal and ethical consequences, failing to make your website accessible can also:

  • Decrease the reach and potential audience of your website
  • Harm your reputation and credibility
  • Reduce the overall user experience for all visitors
  • Result in a loss of potential customers or clients

  • Using descriptive link text that clearly indicates the target of the link

Challenges and obstacles you may encounter in implementing WCAG 2.2 AA and how to overcome them

Implementing WCAG 2.2 AA can be challenging, especially for large and complex websites. Some common obstacles that you may encounter include:

  • Limited budget and resources: Implementing accessibility can require significant time and financial resources.
  • Limited knowledge and expertise: Ensuring that your website meets the WCAG 2.2 AA standard can be complex and may require specialized knowledge and expertise.

When you do make the decision to adopt accessibility online, apart from potential government regulations, WCAG 2.2 AA is probably the standard you should aim for. There are technical teams that specialize in website design accessibility and can provide an audit of your existing site.
