How ESO's Accessibility Testing tool Works

Ensure your website complies with WCAG and provides an inclusive experience for everyone:

The Accessibility Checker from Elite Site Optimizer helps you identify issues that make it difficult for people with disabilities to access your website. It scans all of your web pages to find any violations of the WCAG 2.1 standards (Levels A and AA). This allows you to create a more friendly digital presence and comply with accessibility laws.


  • Degree Sign 24/7 Automated Page Scanning
  • Using advanced accessibility testing engines, ESO crawls and scans your website to identify potential accessibility issues. It inspects HTML, CSS, ARIA roles, and interactive elements to identify accessibility issues.

  • Degree Sign WCAG 2.2 Evaluation
  • We check each page against the last Web Content Accessibility Guidelines (WCAG 2.2). The tool highlights problems that affect screen readers, keyboard navigation, people with visual impairments, and people with common disabilities.

  • Degree Sign Detailed Reports and Fixed Guidance
  • Elite Site Optimizer gives you easy-to-understand reports that you can use to fix problems, such as: Recommended fixes with guidance that is easy for developers to understand. This enables the development, QA, and content teams to quickly resolve issues without requiring extensive manual testing.

  • Degree Sign Continuous Compliance Monitoring
  • ESO helps your team monitor accessibility improvements over time by allowing you to schedule scans and track progress. Discover regressions, maintain WCAG compliance over time, and enhance the experience for all visitors.

  • Degree Sign Issue Severity Classification
  • To prioritize fixes, each issue is categorized into three categories as follows:
    Critical —blocks access completely (e.g., no labels on forms or inaccessible navigation).
    Serious —disrupts usability but might have partial workarounds (e.g., poor contrast or missing headings).
    Minor —best practices not followed (e.g., redundant ARIA labels or minor focus order issues).

How Color Contrast Checker Works
The tool scans all the text elements that are visible and checks them against the WCAG 2.1 standards. It precisely identifies minimum contrast ratios by flagging specific issues related to element references, color values, and actual contrast ratios.
