Full Lighthouse reports across every page of your site.

Lighthouse Audit

Google Lighthouse is the industry-standard tool for measuring page quality across Performance, Accessibility, SEO, and Best Practices. The problem? Lighthouse only audits one page at a time. Running it manually across a 500-page site would take hours. EchoBat integrates Lighthouse directly into its crawl pipeline — every sampled page gets a full Lighthouse audit automatically, and results are aggregated into a site-wide view.

How It Works

During the crawl, EchoBat's Render engine launches headless Chrome to run full Lighthouse audits on sampled pages. Results are stored per-page with all four category scores plus individual audit details. The Lighthouse lens computes a weighted composite score and ranks pages worst-first. Failing audits are grouped by category so you can batch-fix Performance issues, then Accessibility issues, and so on.

Proof Returned in the Report

Every Lighthouse 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

  • Performance Score: Speed Index, Time to Interactive, Total Blocking Time, and render metrics for each page.
  • Accessibility Score: WCAG violations including color contrast, ARIA attributes, keyboard navigation, and semantic HTML.
  • SEO Score: Crawlability, mobile-friendliness, link text quality, and structured data validation.

Why It Matters

  • Site-wide Lighthouse coverage — not one page at a time
  • Composite scoring makes it easy to compare pages
  • Failing audits surfaced per page with Google's own fix recommendations
  • Track Lighthouse score trends across multiple scans
