WCAG compliance checks across every page.

Accessibility Audit

Web accessibility ensures that people with disabilities can perceive, navigate, and interact with your website. Beyond ethical obligations, accessibility is a legal requirement in many jurisdictions (ADA, EAA, AODA) and a Google ranking factor. Common issues include missing alt text on images, poor color contrast, broken heading hierarchies, and missing language declarations. EchoBat combines its own HTML analysis with Lighthouse accessibility audits to provide comprehensive coverage.

How It Works

EchoBat's crawler extracts HTML structure on every page: heading tags, image alt attributes, lang attributes, and ARIA roles. The Accessibility lens analyzes these for WCAG violations. When Lighthouse audits are available (from the Render engine), the lens enriches its findings with color contrast checks, tap target sizes, and more. Results are grouped by issue type and sorted by page count, so the most widespread problems surface first.

Proof Returned in the Report

Every Accessibility Audit finding is tied to crawl evidence: affected URLs, the source signal, severity, score impact, and the next action exposed in the portal, CLI JSON, and MCP tools.

Sample Evidence Fields

  • Image Alt Text: Detects images missing alt attributes, which screen readers cannot describe to visually impaired users.
  • Heading Hierarchy: Validates logical heading order (H1 through H6) and detects skip-levels that confuse screen readers.
  • Document Language: Checks for html lang attribute required by screen readers to select the correct speech synthesis.

Why It Matters

  • Comprehensive WCAG compliance checking across your entire site
  • Combines automated HTML checks with Lighthouse accessibility audits
  • Helps meet legal requirements (ADA, EAA, Section 508)
  • Accessibility improvements often correlate with better SEO rankings
