Core Web Vitals directly affect your ranking on Google. Optimizing LCP and CLS in Angular requires deferring non-critical styles and pre-connecting to content servers. Learn more about performance tuning at Angular performance optimization.

Largest Contentful Paint (LCP) Optimization

LCP tracks when the primary visual block renders on the screen. Optimize it by: preloading hero images, deferring slow third-party analytics code until page hydration completes, and choosing server-side rendering (SSR) to serve static markup.

Cumulative Layout Shift (CLS) Reduction

To keep layout shifts close to zero, always define width and height attributes on static images, reserve sizes on dynamic lists, and use CSS aspect-ratio properties for media assets.
