Why It Converts
Fast enough for a landing page, useful enough for real work.
The home page explains the product, ranks for performance-analysis intent, and still gives immediate value. That means less friction for first-time visitors and a shorter path from discovery to analysis.

CLS, render-blocking resources, and lazy-images-above-the-fold checks are now part of the product.
Next up
