Is your website truly accessible to everyone? Our Web Accessibility Checker helps you find out in seconds. Created for developers, agencies, and website owners, this accessibility testing tool scans your pages and identifies barriers based on the latest WCAG 2.1 guidelines. Whether you run a blog, e-commerce, or institutional site, digital inclusion has become a must — not just for compliance, but for offering a better user experience for all.

Why use a Web Accessibility Checker?

A web accessibility checker allows you to analyze your website and detect usability issues that may prevent visitors from interacting properly with your content. Accessibility testing is essential for ensuring your site meets global standards and supports users with disabilities who use assistive technologies such as screen readers or voice navigation tools.

According to the World Wide Web Consortium (W3C), millions of users still encounter accessibility errors daily — from low-contrast text to unlabeled buttons and missing alt attributes. By regularly scanning your website, you make it usable for everyone, regardless of their abilities, device, or context.

Run a Free WCAG Compliance Audit

Our WCAG compliance audit feature allows you to perform a deep analysis of your pages and verify alignment with WCAG 2.1 standards. The audit provides insights into the accessibility level of each page, showing you exactly what needs improvement to reach full compliance. The audit results can also be exported for documentation or client reports.

Businesses subject to accessibility laws can use these reports to demonstrate commitment to digital inclusion and transparency. Keeping your audit history helps you track progress and show compliance to regulators or partners.

Why accessibility matters for SEO and business

Search engines increasingly reward accessible websites because they are better structured and provide a smoother user experience. When you optimize your website for accessibility, you automatically improve your SEO performance too.

Accessibility-friendly websites tend to have:

  • Cleaner HTML and semantic headings that Google understands better.
  • Descriptive alt texts that improve image indexing.
  • Lower bounce rates due to improved readability and navigation.
  • Higher engagement because users can interact more easily with your content.

In short, making your site accessible isn’t just about compliance — it’s about expanding your reach and building trust with your audience.

Compliance and Legal Requirements

From 2025, the European Accessibility Act (EAA) will make accessibility mandatory for most digital services across the EU. Websites that are not compliant with WCAG 2.1 risk fines, reputational damage, and loss of customers. Using a web accessibility checker and performing a WCAG compliance audit regularly helps you stay compliant and prepared for evolving regulations.

Accessibility laws aren’t only about penalties — they represent a commitment to fairness and inclusion. Businesses that invest in inclusive web design demonstrate respect for their users and strengthen brand credibility.

Beyond automatic checks

While automated tools like ours can detect most accessibility issues, complete compliance also requires human review. Manual testing ensures that dynamic and interactive elements meet usability expectations. That’s why our reports guide developers and UX professionals toward a holistic accessibility strategy.

After running your free scan, you can contact our consultants to perform a full audit and remediation service. We’ll help you make your website fully compliant, user-friendly, and future-proof.
