Learn how a web app development company can conduct web accessibility audits with essential tools and tips for compliance and improvement. Ensure your websites and web apps are accessible to all users, enhancing user experience and legal compliance.
Introduction
Web accessibility has become an essential prerequisite for contemporary websites. Web accessibility can be defined as the process of properly designing and creating websites and web applications to be usable by a far-reaching population, including those with disabilities.
This ranges from the visually impaired, the hearing impaired, the mentally impaired, and those with physical disabilities. For a web app development company, web accessibility audits also play an important role in finding out the barriers that hinder users from effectively accessing web services.
The following article looks at why web accessibility is crucial, what tools can be employed to perform an audit, and a practical guide of how to be compliant and enhance user experience.
The Importance of Web Accessibility
Web accessibility is not just a legal requirement but a moral imperative. It ensures that everyone, regardless of their abilities, has equal access to information and services online. Here are some key reasons why web accessibility is important:
Inclusivity and Equality
Web accessibility promotes inclusivity by providing equal access to information and services for all users. This is crucial in creating an equitable digital environment.
Legal Compliance
Many countries have enacted laws and regulations that mandate web accessibility. In the United States, for example, the Americans with Disabilities Act (ADA) and Section 508 of the Rehabilitation Act require that websites be accessible to people with disabilities.
Improved User Experience
Accessible websites are generally easier to navigate and use, benefiting all users, not just those with disabilities. This can lead to increased user satisfaction and engagement.
Enhanced SEO
Accessible websites are often more search engine friendly. Features that improve accessibility, such as descriptive alt text for images and proper use of headings, can also enhance search engine optimization (SEO).
Broader Audience Reach
By making your website accessible, you can reach a larger audience, including the millions of people worldwide who have disabilities.
Conducting Web Accessibility Audits
A web accessibility audit is a thorough evaluation of a website to identify barriers that may prevent people with disabilities from accessing its content. These audits involve both automated and manual testing to ensure comprehensive coverage. Here are the key steps involved in conducting a web accessibility audit:
Define the Scope
Before starting the audit, it’s important to define the scope of the evaluation. This includes identifying which pages and elements of the website will be tested. Consider prioritizing high-traffic pages and pages that are critical to the user experience, such as the homepage, contact page, and forms.
Use Automated Testing Tools
Automated testing tools can quickly identify common accessibility issues across a website. While these tools are useful for initial assessments, they should not be relied upon exclusively, as they may not catch all issues. Some popular automated testing tools include:
WAVE
Web Accessibility Evaluation Tool (WAVE) provides visual feedback about the accessibility of web content by injecting icons and indicators into the page.
axe
An open-source accessibility testing tool that can be integrated into browsers and development environments.
Lighthouse
A tool integrated into Google Chrome’s DevTools that performs accessibility audits and provides scores and recommendations.
Conduct Manual Testing
Manual testing is essential for identifying issues that automated tools may miss. This involves using assistive technologies, such as screen readers and keyboard navigation, to evaluate the website’s usability. Key aspects to test manually include:
Keyboard Navigation
Ensure that all interactive elements can be accessed and operated using only the keyboard. This includes links, buttons, and form controls.
Screen Reader Compatibility
Use screen readers, such as JAWS, NVDA, or VoiceOver, to test how well the website content is read aloud and navigated.
Color Contrast
Verify that text has sufficient contrast against its background to be easily readable by users with visual impairments.
Evaluate Against Accessibility Standards
Web accessibility standards, such as the Web Content Accessibility Guidelines (WCAG), provide a set of criteria for making web content accessible. WCAG 2.1, the most widely adopted standard, is organized into four principles:
Perceivable
Information and user interface components must be presentable to users in ways they can perceive.
Operable
User interface components and navigation must be operable.
Understandable
Information and the operation of the user interface must be understandable.
Robust
Content must be robust enough to be interpreted by a wide variety of user agents, including assistive technologies.
Evaluate your website against these principles and the specific success criteria outlined in WCAG 2.1.
Document Findings and Recommendations
After completing the audit, document the findings, including a list of identified issues and recommendations for remediation. Prioritize issues based on their impact on accessibility and user experience. Provide clear instructions for fixing each issue, including code snippets or references to best practices where applicable.
Implement Remediation
Work with your development team to implement the recommended changes. This may involve updating HTML, CSS, and JavaScript code, as well as making adjustments to design and content. Ensure that changes are tested for accessibility before deploying them to the live website.
Perform Ongoing Monitoring
Web accessibility is not a one-time task but an ongoing commitment. Regularly monitor your website for accessibility issues, especially after making updates or adding new content. Consider integrating accessibility testing into your development and quality assurance processes.

Include descriptive alt text for images, transcripts for audio content, and captions for videos. This ensures that users who cannot see or hear the content can still understand it.
Use Clear and Consistent Navigation
Design a clear and consistent navigation structure that helps users find information easily. Use descriptive link text and headings.
Avoid Using Color Alone to Convey Information
Do not rely solely on color to convey information. Use text labels or patterns in addition to color.
Development Tips
Use Semantic HTML
Use HTML elements according to their intended purpose. For example, use <header>, <nav>, <main>, and <footer> to define the structure of your content.
Ensure Form Accessibility
Label form controls clearly, provide instructions and error messages, and ensure that forms can be submitted using the keyboard.
Implement ARIA Landmarks and Roles
Use Accessible Rich Internet Applications (ARIA) landmarks and roles to enhance the accessibility of complex web applications.
Test with Assistive Technologies
Regularly test your website with assistive technologies such as screen readers and keyboard navigation to ensure compatibility.
Content Creation Tips
Write Clear and Concise Text
Use plain language and concise sentences to make content easier to read and understand.
Organize Content with Headings
Use headings to organize content into logical sections. This helps screen reader users navigate the page more easily.
