Methodology

  • Identical hero + body layout with the same text and 3 images.
  • Vendor-recommended hosting/CDN with default settings.
  • Lab runs (5×, median) with network/CPU throttling; normalized to 0–100 where higher is better.

Limitations: 3rd-party apps, custom code, and content choices can significantly change your CWV. Treat these as directional.
