What it means
It indicates when the main large text block, banner or image becomes visible after the visitor opens the page.
Term in plain language
LCP
A metric measuring the time until the largest visible content element renders in the viewport.
Why it matters
A slow LCP means the main content remains hidden because of server time, images, fonts or render-blocking resources.
Example
The hero image is compressed, dimensioned and loaded without lazy delay to improve LCP.
