Why do FCP and LCP matter?
Core Web Vitals describe how quickly a page starts to feel useful.
FCP
Faster first contentful paint
FCP measures how quickly the first image or text appears. Seeing content reassures visitors that the page is loading successfully.
LCP
Quicker largest contentful paint
LCP measures when the biggest piece of content appears. A fast LCP makes visitors less likely to navigate away.
Conversion impact
A one-second delay can reduce conversion rates by 20%
Fast pages keep visitors moving toward the content, products, and actions they came for.
