Boosting Stability and Speed for Better Ad Performance
Optimized Brock’s Performance Core Web Vitals, boosting homepage CLS by 200% and category CLS by 180%, and cutting CPC ad costs by 30%.
Challenge
Unstable Layout & Slow Paint
Brock’s Performance was experiencing high Cumulative Layout Shift (CLS) on both their home and category pages, causing layout instability, while product pages suffered from slow Largest Contentful Paint (LCP). These issues not only hurt user experience but also drove up their cost per click in ad campaigns due to lower quality scores.
