When building websites or apps, accessibility testing is critical to ensure that what you build will work for all your users, including users with disabilities and also people with temporary and situational limitations.

Taking a layered approach to testing your site for accessibility also improves the usability of your site — which in turn increases your customer base and reduces customer service inquiries. It can both make and save you money.

There are different types of analogies and layers of accessibility, including the so-called layered cake analogy. Food analogies have become quite popular in the accessibility world!

When accessibility testing, there are two points of view – mechanical angle, as well as user experience.

Combining many types of accessibility testing throughout the product development life cycle is a powerful way to improve overall product accessibility.
