Core Web Vitals Optimization
Optimized page speed resulting in better rankings and 32% higher conversions
Overview
A SaaS platform needed to improve Core Web Vitals scores to maintain and improve search rankings after a Google algorithm update focused on page experience.
The Challenge
LCP was consistently above 4 seconds, CLS scores were high due to dynamic content loading, and INP was sluggish on mobile devices. These issues were directly affecting search rankings and user retention.
The Solution
Optimized server-side rendering, implemented image preloading, reduced CSS and JavaScript payload, added font-display: swap for web fonts, implemented content-visibility for below-the-fold content, and optimized the server response pipeline.
Results
LCP improved to 1.8s, CLS dropped to 0.05, and INP fell below 200ms. Organic rankings improved for key terms, conversions increased by 32%, and bounce rate decreased by 15%.
