With Google’s emphasis on Core Web Vitals, website speed is no longer optional—it’s a requirement for ranking and user retention.

### 1. Optimizing LCP (Largest Contentful Paint)
LCP measures perceived load speed. We optimize this by prioritizing critical CSS, using high-performance image formats (WebP), and leveraging CDNs to serve assets closer to the user.

### 2. Reducing FID (First Input Delay)
FID measures responsiveness. Minimizing JavaScript execution time and breaking up long tasks ensures that the browser remains responsive to user interactions.

### 3. Improving CLS (Cumulative Layout Shift)
CLS measures visual stability. We avoid unexpected layout shifts by always specifying dimensions for images and ads, and avoiding inserting content above existing content.

VDPL’s performance engineering team in Noida specializes in taking slow, legacy platforms and transforming them into lightning-fast, Core Web Vitals compliant applications.
