Why do FCP and LCP matter?

Faster FCP

First contentful paint (FCP) is how quickly the first image or text is displayed on screen.

Once someone sees content appearing, they are reassured the page is loading successfully.

Quicker LCP

Largest contentful paint (LCP) is when the biggest piece of content is displayed.

It gives the page a fast loading feel. As a result, a visitor is less likely to navigate away from the page.
