What does Rendering Checker do?

Compare raw HTML vs. JavaScript-rendered output — see exactly what Google sees.

How do I use Rendering Checker?

Launch a real headless browser and compare the raw HTML of any page (no JavaScript) against the fully rendered version (JavaScript executed). Instantly shows which SEO-critical elements — title, meta description, canonical, headings, links — are added or changed by JavaScript. A JS Dependency score tells you at a glance whether your content relies on JavaScript to be visible to search engines.
