What is WCAG Compliance?

WCAG (Web Content Accessibility Guidelines) is a set of guidelines that are formulated by the Web Accessibility Initiative (WAI) of the World Wide Web Consortium (W3C). It ensures that the web content is accessible to all, including people with disabilities. 

WCAG covers a wide spectrum of disabilities under its guidelines, such as visual, auditory sensory, speech, physical, cognitive, linguistic, learning, and neurological disabilities.

There are three different versions of WCAG compliance in popular use: 

  • WCAG 2.0 
  • WCAG 2.1
  • WCAG 2.2
  • WCAG 3.0 (development in-progress).

Why is WCAG Compliance important?

An Accessibility audit of Fortune 100 corporate websites identified 815,600 WCAG 2.1 accessibility issues, out of which, the majority were Level A issues. This shows that Fortune 100 companies are failing to meet basic criteria for accessibility compliance. This apart, 90% of websites are inaccessible to people with disabilities relying on assistive technology.

This indicates how WCAG testing is essential. Web Accessibility not only holds moral responsibility, but it also holds business implications.

Web Accessibility helps businesses to: 

  • Target Larger Audience
  • Increase Awareness and Avoiding Legal Ramifications
  • Enhance Brand Recognition

Target Larger Audience

Did you know an estimated 1.3 billion people – or 1 in 6 people worldwide – experience significant disability as per WHO. 

WCAG helps target a larger audience who otherwise would not be able to consume the web content due to one or the other disability. Gartner suggests that by 2023, digital products that fully conform to WCAG 2.0 compliance are expected to outperform their market competitors by 50%.

Business opportunities in WCAG compliance are significant as the Digital Accessibility TAM (Total Addressable Market) was valued at USD 484.70 million in 2020. It is projected to reach USD 769.50 Million by 2028, growing at a CAGR of 5.99% from 2021 to 2028, which means Web Accessibility should not be missed.

Increase Awareness and Avoiding Legal Ramifications

There’s an increased sense of awareness towards web accessibility with assistive tools in the market more than ever. The number of Web Accessibility Lawsuits has risen exponentially, so much so that it has doubled in 2023 since 2018.

Enhance Brand Recognition

Demonstrating a commitment to WCAG compliance reflects an inclusive approach, ensuring that individuals with disabilities can access and engage with your digital content. This inclusivity contributes to a positive brand image and showcases a commitment to diversity.

Being WCAG compliant is a good way to avoid Lawsuits and ensure business growth with a larger target audience.

Who should follow WCAG Compliance

WCAG Compliance is used for Accessibility by:

  • Developers to build a website that considers easy access to all, fix the accessibility issues, and debug for any failing accessibility standards and criteria.
  • QAs to test whether all the accessibility guidelines and criteria are successfully met by thoroughly testing the application against the success criteria prescribed by WCAG.
  • UX Designers for creating an all-inclusive interface design that is accessible and usable by as many people as possible, regardless of their age, ability, or status. 
  • Product Managers evaluate accessibility pre-requisites, verify accessibility with ease, and access WCAG-mapped issues to create VPAT reports and monitor them.

4 Key Principles of WCAG Compliance

WCAG compliance is based on the 4 Key Principles:

  • P- Perceivable
  • O- Operable
  • U- Understandable
  • R- Robust

These key principles are based on the abilities of vision, hearing, motor skills, and cognition, which thoughtfully include people from different categories of disabilities within the compliance. 

Perceivable

Users should be able to perceive the information mentioned on the website. It should be presented in a format which can be easily read/ processed by the reader. The website should have text that is clearly visible to the users with issues such as:

  • Visually impairment: The website content must be consumable by screen readers and assistive technologies meant for the visually impaired.
  • Color-blindness: Ensure a good contrast between the foreground and background of the website for better readability of the content. 
  • Hearing impairment: Add text/subtitles for every audio/video to help them consume the content easily. 

Operable

Websites should be easy to use, irrespective of disabilities. Components of the UI should be designed in a way that they can be operated with ease. 

  • Users with motor disabilities might have issues using the mouse, so alternative options for the keyboard should be provided. 
  • For people with cognitive disabilities, animations and media should be controllable, and time limits for completing an action should be generous.
  • Options to cancel, go back, alerts and warnings should be available to make sure people make fewer mistakes and operate with ease. 
  • Any time-bound activities should be designed in a way so that persons with cognitive disabilities can operate it.

Understandable

Although users might successfully perceive or operate the website, they might still not be able to understand its context. A website should have content that can be understood easily. For users to easily comprehend, content should be presented using concise and clear language. 

A clear set of instructions/guidelines should be available to help users perform actions. The connection between the action and the result should be clear and obvious. 

This can be done using meaningful and logical workflows that are clearly indicated by well-marked navigation. Usability must be well taken into consideration, such as:

  • If a user must go through a critical process like a checkout — adequate guidance should be provided.
  • Forms should nudge users to provide the relevant information using clear labels. 

Robust

With multiple options available, users are free to choose their own agent such as browser, OS, platforms, and devices to access a website. Any website which restricts the user to a specific technology does not conform to accessibility standards. 

A website should be compatible with different agents including assistive technologies like screen readers. This would help all users get a consistent user experience irrespective of which set of technologies and agents they use to access the content on the website. 

WCAG Guidelines

WCAG 2.0 has 12 guidelines classified under the 4 key Principles (POUR) discussed above. Each of these guidelines has success criteria defined under them based on the conformance levels. On the other hand, WCAG 2.1 is backward compatible with WCAG 2.0, with 1 additional guideline mentioned below:

1.Perceivable
1.1Text AlternativesProvide Text Alternatives to different non-text content forms so that it can be used by assistive technology such as screen readers, braille, large print, symbols, or easy language.
1.2Time-based MediaProvide Captions, alternatives or audio descriptions for pre-recorded and live time-based media such as audio or video.
1.3AdaptableCreate content that is adaptable to different forms without losing out on the information or its structure.
1.4DistinguishableMake content easier for the user to see and hear so that they can separate the foreground from the background.
2.Operable
2.1Keyboard AccessibleMake all the functionality of the website accessible from a keyboard without requiring specific timings for individual keystrokes.
2.2Enough TimeGive enough time to the users to read and act on the content.
2.3SeizuresContent design should not have anything that flashes more than 3 times to avoid causing seizures due to photosensitivity.
2.4NavigableHelp users navigate through the workflows and webpages, find content, and determine where they are on the website.
2.5Input Modalities
(WCAG 2.1 & WCAG 2.2)
Make it easier for the users to operate functionalities using different inputs apart from the keyboard.
3.Understandable
3.1ReadableCreate content that is readable and easy to understand using clear and simple language.
3.2PredictableDesign content and pages in a predictable way, where users can easily predict how to operate.
3.3Input AssitanceHelp users provide correct information and correct mistakes through ways like clear instructions and error prevention techniques.
4.Robust
4.1CompatibleCreate a website with maximum compatibility with the current and future user agents such as browsers, devices, and platforms, including assistive technologies.
