# Optimizing Next.js Applications for Core Web Vitals

Core Web Vitals are a set of specific factors that Google considers important in a webpage's overall user experience.

## LCP (Largest Contentful Paint)

To improve LCP, ensure your main image or text block loads quickly. Use `next/image` with the `priority` prop for above-the-fold images.

## CLS (Cumulative Layout Shift)

Avoid layout shifts by always specifying dimensions for images and using font-display: optional or swap strategies properly.

## Dynamic Imports

Use `next/dynamic` to lazy load heavy components that aren't critical for the initial render.

## Conclusion

Next.js provides powerful built-in tools for performance, but it's up to developers to use them correctly.
