Core Web Vitals

This is the time it takes for the page’s main content to appear.

FID (First Input Delay)

This is how quickly the page responds to the user’s first interaction.

CLS (Cumulative Layout Shift)

This measures how much the page layout shifts while it’s loading.

Image Optimization

Next-Gen Formats

By using WebP or AVIF, you can significantly reduce file sizes.
