Sample Article A (Already Indexed)

This is Article A — an already-indexed article that Googlebot visits periodically.

When Googlebot's Web Rendering Service (WRS) renders this page, the VBC script will detect SwiftShader and trigger a silent fetch for Article B.

How VBC Works

The script checks WebGL renderer for SwiftShader (Google's software renderer used in WRS). Once detected, it fetches the next pending URL and sends a beacon to our API.

Why This Works

Googlebot's WRS executes JavaScript and fetches all sub-resources. When our script calls fetch('article-b-url'), the request comes from Google's IPs — which means Googlebot effectively crawls Article B.
