See your site the way Googlebot does.

JavaScript Rendering

Modern websites built with React, Angular, Vue, and other JavaScript frameworks often render content client-side. Search engines must execute JavaScript to see this content — and they don't always do it correctly or promptly. EchoBat's Render engine uses headless Chrome to fully execute JavaScript on every sampled page, extracting the final rendered DOM. This shows you exactly what search engines see after JavaScript execution, revealing content that may be invisible to crawlers.

How It Works

EchoBat's Render engine launches headless Chrome instances during the crawl. For sampled pages, it loads the page, waits for JavaScript execution and network idle, then extracts the final DOM, screenshots, and any additional links discovered. This rendered content is used by the SEO, accessibility, and structured data lenses — ensuring their analysis reflects what search engines actually see, not just the raw HTML source.

Why It Matters

  • See content exactly as Googlebot renders it — after JavaScript execution
  • Discover links and content invisible in static HTML
  • Catch SPA routing issues that prevent page discovery
  • Visual screenshots for quick verification across the site
