Top Online Web Accessibility Checkers to Improve Your Website in 2023

Imagine browsing a website and encountering a wall of obstacles—tiny text, confusing navigation, or images without descriptions. For many, this is a daily reality. As we spend more of our lives online, ensuring everyone can access digital content isn't just considerate; it's essential. That's where online web accessibility checkers come into play.

These tools help us identify and fix accessibility issues on our websites, making them usable for all. With the rise of digital inclusivity, companies like Bussler & Co are leading the charge, offering cutting-edge solutions to enhance web accessibility. As we explore the world of online web accessibility checkers, we'll discover how they empower us to create a more inclusive internet for everyone.

Understanding Online Web Accessibility Checkers

Online web accessibility checkers evaluate websites to ensure they meet accessibility standards. These tools reference guidelines like WCAG 2.0 and 2.1, Section 508 of the Rehabilitation Act, and other international standards. They scan websites for issues that affect user accessibility and provide actionable feedback. Users can enter a URL or upload an HTML file to initiate scans, and many offer browser extensions for further convenience.

1. Navigation and Orientation: Checkers assess site navigation for consistency and accessibility. They ensure users can easily find and access different sections of the site.
2. ARIA Implementation: Tools verify the correct use of ARIA attributes, enhancing accessibility for individuals with disabilities. Proper ARIA implementation is crucial for enabling assistive technologies to interpret web content correctly.

Key Features to Look For

Online web accessibility checkers play a vital role in ensuring websites are inclusive for all users. Understanding the essential features of these tools helps us choose the best one for our needs.

Automated Testing

Automated testing is crucial for efficiently identifying accessibility issues. Tools like accessScan use AI engines from accessiBe to simulate human testing, ensuring thorough evaluation against WCAG 2.1 Level AA guidelines. Similarly, Deque's Free Website Accessibility Test offers swift scans, highlighting key issues with a summary report. WAVE Web Accessibility Evaluation Tools leverage both online tools and browser extensions to identify potential problems while supporting human intervention if required.

Compatibility with Standards

Adherence to recognized standards ensures the credibility and effectiveness of accessibility checkers. accessScan is specifically designed to ensure full compliance with WCAG 2 standards. By focusing on these guidelines, it guarantees compatibility and conformance, ensuring our digital platforms meet the necessary accessibility benchmarks.

User-Friendliness

User-friendliness is essential for maximizing the utility of accessibility tools. An intuitive interface simplifies the scanning process and report interpretation. For instance, browser extensions available in some tools streamline accessibility checks, allowing quick integration into our daily website maintenance routine. This ease of use encourages regular evaluations, fostering continuous improvement of web accessibility.

Benefits of Using Web Accessibility Checkers

Web accessibility checkers offer several advantages that make them indispensable for ensuring websites are accessible to users with disabilities.

Compliance with legislation such as the Web Content Accessibility Guidelines (WCAG) 2.1, Section 508, and the Americans with Disabilities Act (ADA) becomes manageable with these tools. They also support other international standards like the Stanca Act and BITV, helping websites meet necessary legal requirements and avoid penalties.

Detailed error reports generated by tools like Intent Based's Accessibility Checker, AChecker, and accessScan assist in identifying accessibility issues. These reports include explanations of the problems, the impact on users, and suggestions for remediation, making it easier to understand and resolve accessibility concerns.

Challenges and Limitations

Incomplete Coverage

Automated tools for web accessibility, while helpful, don't cover all aspects comprehensively. Tools like Lighthouse in Chrome devtools don't perform the full set of tests that more sophisticated tools such as axe-core conduct. As a result, a site might achieve a high accessibility score yet still harbor significant issues that remain unaddressed.

False Positives and Negatives

Automated accessibility checkers sometimes misidentify elements, which results in false positives or negatives. For instance, Microsoft's Accessibility Checker might flag non-problematic elements as issues or ignore critical missing alt text in tables, misleading users about a site's true accessibility status.

Lack of Contextual Understanding

These tools often fail to grasp the content's context, which can lead to inaccuracies. Even if alt tags are present, they might be inaccurate in describing the visuals. This illustrates a key limitation where human review remains irreplaceable to ensure that web content is both accessible and contextually accurate.
