A key factor in the success of an online business is website accessibility. There is an increasing need for websites to provide accessible material to all users as ecommerce retailers fast close the retail sales gap and more users than ever are prepared to utilize online services for financial, health, and legal assistance.

Because of this, it’s essential that you follow web accessibility principles while designing and test those design components to make sure they function as intended.

 

Improved Accessibility is Required

There are many people who suffer from “a disability that impacts major life activities.” These impairments fall under six broad categories:

 

  1. Mobility: Challenges using the stairs, walking, and reaching physical infrastructure
  2. Cognition: Problems with focus, memory, or decision-making
  3. Hearing: Difficulty hearing digital media and/or conversations
  4. Vision: Difficulty viewing videos or reading text
  5. Independent Living: Difficulty doing basic daily activities like running errands or preparing food that are necessary for independent living.
  6. Self-care: Problems with daily activities including dressing or bathing

 

Your company may boost its pool of prospective clients by 25% and enhance customer loyalty by focusing on this accessibility campaign and making website modifications for people with impairments like these. 

 

Let’s now go through what online accessibility testing involves.

 

What Does Testing for Web Accessibility Entail?

The process of assessing how readily people with impairments can use a website is known as web accessibility testing. Web accessibility testing, a subcategory of usability testing, makes sure that all users can comprehend, browse, and engage with a website. This offers useful data for enhancing next designs for users with and without impairments.

According to Web Accessibility Initiative (WC3), “accessibility evaluation is more formalized than usability testing generally.”

 Four objectives are emphasized in well-designed accessibility testing:

  • providing for the requirements of all disabled individuals
  • juggling the demands of various disability groups
  • the best methods for these demands
  • Expressing those demands and strategies in plain words

Web accessibility testing, to put it simply, verifies that the features and services added to websites to promote accessibility are operating as intended.

 

Tests to Perform

Testing a website for accessibility should look at two important results: universality and usability.

 

A website’s universality refers to its components and features that are accessible to all users. For instance, lowered curbs on pathways and sidewalks provide universal access, which benefits both customers with normal mobility and those who are less mobile. Usability, on the other hand, refers to how straightforward and useful components of accessible design are. Your website’s chances of picking visitors’ attention are enhanced if it is simple to use.

It’s important to take into account each of the six CDC categories we listed above when doing a successful online accessibility test:

 

Mobility: How can people who have mobility issues visit your website? There is a straightforward beginning test, as highlighted by Karl Groves, creator of the Tenon.io online accessibility platform: Switch off your mouse. All of the controls on your website are accessible to you. Are the controls that are now in use visible to you? Do instructions from command make sense? If the response is negative, you must enhance keyboard support.

 

Cognition: How difficult to use are the menus and forms on your website? For persons with cognitive problems, are they relevant to the context and simple to identify? Does each form field specifically state what users must enter? Consider shifting any form requirements that are hidden inside field boxes outside.

 

Hearing: Do you offer solutions for folks who are hard of hearing if your website has several videos or sound clips? This includes transcripts for podcasts, product descriptions, and other audio content as well as closed captioning for videos.

 

Vision: Do your website’s audio descriptions and context-first text, which enables visitors with disabilities to use text-to-voice software to discover information more easily, support the opposite?

 

Living Independently: Here, ease of usage is crucial. Users who struggle with independent living are frequently capable of completing progressively difficult activities as long as they follow clear and basic instructions. Because of this, it’s simpler for these visitors to find what they’re looking for on a site with an organized layout.

 

Self-care: Despite their physical or cognitive limitations, many people who struggle with self-care nonetheless have very sharp minds. In this situation, text and graphic components that are readily scalable can save unnecessary annoyance for these users.
