A global B2B directory with 850,000 indexable software profiles was failing Google's Core Web Vitals assessment. The origin server in North America caused 800ms+ Time to First Byte (TTFB) and a 3.8-second Largest Contentful Paint (LCP) for users in Europe and Asia, resulting in declining ranking positions for competitive software queries.
WebKernelAI's Page Speed Optimizer identified that static directory pages were being dynamically rendered on the origin server for every request. Additionally, uncompressed PNG screenshots and blocking render stylesheets delayed initial layout rendering.
We implemented Cloudflare Cache Rules to cache the static HTML at 300+ global edge data centers with a 7-day stale-while-revalidate TTL. We enabled Early Hints (HTTP 103 status code) to preload critical fonts and CSS before the main document resolved, alongside Polish for automatic AVIF/WebP image optimization. Average global LCP dropped to 1.1s, qualifying all 850,000 URLs for Google's Page Experience ranking boost.
Cache Rules store fully rendered HTML pages directly on Cloudflare's global edge network, allowing nearby users and Googlebot to receive responses in under 50ms without pinging the origin server.
Early Hints sends a preliminary response header instructing the browser to download critical fonts and stylesheets while the main server is still processing the request.
WebKernelAI checks for JavaScript rendering timeouts, duplicate canonical tags, redirect loops, and server vulnerability markers.
