About Siteimprove Accessibility Checker

Is your website accessible for everyone? Evaluate and improve accessibility right inside your browser with the Siteimprove Accessibility Checker for Chrome. The Siteimprove Accessibility Checker makes it easy to assess any web page, including non-public or password-protected content, directly in your browser. Instantly identify issues based on the latest ACT (Accessibility Conformance Testing) rules and receive actionable recommendations and examples to fix issues. Now with a new look-and-feel and enhanced support for designers, our latest update includes a Design Kit with guidance for color contrast, image alt text, heading hierarchy, focus indicators, and more. Plus, you can see how your site looks to people who are color blind with our various color blindness tools.

Kickstart your accessibility efforts today to ensure your website is accessible for everyone. - Instant analysis: Use the Issues tab to get an immediate overview of your web pages' accessibility
 - Breakdown and clear explanations: Understand how each of the detected issues affects your visitors.
 - Hands-on guidance: Get detailed recommendations, code snippet examples, and links to relevant WCAG techniques to fix issues. The Siteimprove Accessibility Checker provides automated accessibility testing within Google's Chrome browser and allows for secure evaluation of any password-protected or non-public pages, multi-step forms, and dynamic content. ------------------------------------------------------ By installing the Siteimprove Accessibility Checker extension for Google Chrome, you are agreeing to our Terms of Service [https://siteimprove.com/en/legal/chrome-extension-tos/] and Privacy Policy [https://siteimprove.com/en/legal/].
