Web Content Accessibility Guidelines (WCAG) Audit


The Web Content Accessibility Guidelines (WCAG) Audit is a set of guidelines designed to ensure that websites and digital content are accessible to people with disabilities. The guidelines are organized into three levels of conformance: A, AA, and AAA. Each level includes specific criteria that must be met in order for the content to be considered accessible. The criteria are organized into four main categories: perceivable, operable, understandable, and robust. The criteria cover a wide range of topics, including text alternatives, keyboard accessibility, and the use of color and contrast. The WCAG Audit guidelines are an important tool for web developers and designers to ensure that their websites are accessible to everyone.

Testing the perceivability of a web page is an important step in ensuring that the page is accessible to all users. The first step in testing perceivability is to ensure that the page has sufficient contrast between text and background colors. Additionally, it is important to make sure that the page is readable without the need for a specific font size or color. Additionally, it is important to make sure that all images and videos have alternative text descriptions and captions. Finally, it is important to make sure that all content is organized in a logical and accessible way, and that all interactive elements are clearly labeled and easy to use. By following these steps, it is possible to ensure that a web page is perceivable to all users.

·       Provide text alternatives for non-text content.

·       Provide captions and other alternatives for multimedia.

·       Create content that can be presented in different ways, including by assistive technologies, without losing meaning.

·       Make it easier for users to see and hear content.

How many of use have seen a link with "Click here? "Testing the operability of a web page is an important step in ensuring that the page is functioning properly. You should check the page's HTML and CSS code to make sure that it is valid and error-free. All functionalities should be keyboard accessible. The links , buttons should have meaningful accessible names for assistive technologies. Finally, you should also test the page's functionality by clicking on links and buttons to make sure that they are working properly. By doing these steps, you can ensure that your web page is operable and functioning correctly.

·       Make all functionality available from a keyboard.

·       Give users enough time to read and use content.

·       Do not use content that causes seizures or physical reactions.

·       Help users navigate and find content.

·       Make it easier to use inputs other than keyboard.

How many of you are tired of seeing "Incorrect phone number format ? "Testing the understandability of the web page is an important step in ensuring that the page is accessible to all users. To test the understandability of a web page, a few key steps should be taken. First, the page should be tested to ensure that all content is written in clear, plain language, avoiding any jargon or technical terms that may be confusing. Next, the page should be tested to ensure that all instructions are easy to follow and that users can easily find the information they need. Finally, the page should be tested to ensure that all interactive elements are easy to use and that users can easily navigate between different parts of the page. Any errors in the page should have clear description and a guiding process, so users can fix the errors independently. By taking these steps, the understandability of a web page can be tested and improved, ensuring that all users can access the content.

·       Make text readable and understandable.

·       Make content appear and operate in predictable ways.

·       Help users avoid and correct mistakes.

Content must be robust enough to be interpreted by a wide variety of user agents, such as browsers, search engines, and assistive technologies. This means that content should be written in a way that is accessible to all users, regardless of the device they are using. By ensuring that content is robust, it can be interpreted by a wide variety of user agents and assistive technologies, allowing all users to access the content.

·       Make parsing clear and flawless

·       Provide ARIA name , roll , value for all interactive elements

Cognitive Accessibility Guidance

The digital content created today can have a huge impact on society, but unfortunately, not everyone can access it. People with cognitive disabilities are particularly affected, as they are unable to access the same digital content as the rest of the population. This can lead to a lack of understanding of the world around them, as well as a lack of access to important information and resources. This can lead to a feeling of isolation and exclusion, as well as a lack of opportunity and advancement. It can also lead to a lack of understanding of the world around them, which can lead to a lack of participation in society. This can have a negative effect on the overall quality of life for those with cognitive disabilities, and can lead to a lack of inclusion in the larger society. Therefore, it is important to ensure that digital content is accessible to all, regardless of their cognitive abilities, in order to ensure that everyone has the same opportunities and access to important information and resources.

Mental health disability is a term used to describe a wide range of mental illnesses, including depression, anxiety, bipolar disorder, and schizophrenia. According to the World Health Organization, approximately one in four people globally suffer from some form of mental health disability as of 2023. This means that approximately 25% of the world's population is affected by mental health disability in some way. 

Making purpose of your page clear, using a consistent visual design, making each step simple and clear, using icons that can help users, helping user understand the overall functionality of your digital content , helping users avoid mistakes and provide clear instructions ensure your digital content is flexible enough for cognitive disable users.

10 Easy Steps to make your digital content accessible

Making digital content accessible doesn't have to be difficult. Here are 10 easy steps you can take to ensure your digital content is accessible to everyone: 


1. Check the HTML structure and semantics - Ensure that the website's HTML structure and semantics are appropriate and semantically correct. This includes using proper heading tags (H1, H2, H3, etc.), labeling form fields, and using alt text for images.

2. Test for non text content -Provide text alternatives for ALL non-text content, such as images, audio, or video.

3. Test for language- Use plain language and avoid jargon. Ensure that all text and images are large enough to be easily read.

4. Test for multimedia accessibility - Provide captions and transcripts for all audio and video content.

5. Test for consistency - Create a consistent page structure and navigation to make the digital content easily understandable.

6. Test for color contrast - Check the color contrast ratio of text and images to ensure that it meets the minimum contrast ratio required for WCAG compliance. Use contrasting colors for text and background. Never use colors as the only sensory element to convey your context.

7. Test for Keyboard Accessibility - Make sure all functionalities are keyboard accessible for your non sighted user community.

8. Test for assistive technology compatibility - Test your content for compatibility with screen readers , color analyzer, magnifiers etc.

9. Test links and user interactive elements - Make sure all links and buttons are clearly labeled and easy to click.

10. Validate the website - Validate the website's code using tools such as the W3C Validator to ensure that it meets web standards and is accessible to all users.

WCAG 2.0 Guidelines and Success Criteria in a list and this image distributes the success criteria according to level A,AA and AAA





WCAG2.0 and P.O.U.R Concept

The Web Content Accessibility Guidelines (WCAG) 2.0 includes a comprehensive set of success criteria organized under the four principles of Perceivable, Operable, Understandable, and Robust (POUR). WCAG 2.0 encompasses a total of 38 success criteria for Level A and an additional 26 success criteria for Level AA accessibility compliance.

In WCAG 2.0, Level A success criteria focus on fundamental accessibility requirements, while Level AA success criteria address more advanced considerations to enhance the user experience for individuals with disabilities. Think of Level A success criteria in WCAG 2.0 as the basic building blocks of accessibility, like providing text alternatives for images (1.1.1) or ensuring keyboard accessibility (2.1.1). On the other hand, Level AA success criteria, such as maintaining sufficient contrast (1.4.3) or offering alternatives for time-based media (1.2.2), take accessibility a step further for a more inclusive and refined user experience.

This list is a comprehensive overview of the WCAG 2.0 success criteria, organized under the Perceivable, Operable, Understandable, and Robust principles. Each success criterion plays a crucial role in ensuring digital content is accessible to a diverse audience.

What is Web Accessibility ?

Web accessibility is the practice of making websites, web applications, and other online content accessible for all users, regardless of their physical or mental abilities. This includes accommodating users with disabilities, such as those with visual, auditory, motor, and cognitive impairments. Web accessibility is important because it helps ensure that everyone can access and use the same content and functionalities regardless of their physical or mental abilities. Without web accessibility, users with disabilities may not be able to access or use the content, which could lead to exclusion and discrimination. Web accessibility also helps to create an inclusive and equitable digital environment, which is important for everyone.
