FCP, FP, LCP

  1. First Contentful Paint (FCP):

    FCP measures the time from when the page starts loading to when any part of the page's content is rendered on the screen. It indicates how quickly users can begin to consume content.

  2. First Paint (FP):

    FP marks the time when the first pixel is rendered on the screen, signaling the start of the page loading process. It provides an initial indication of load performance.

  3. Largest Contentful Paint (LCP):

    LCP measures the time from when the page starts loading to when the largest text block or image element is fully rendered within the viewport. It reflects the perceived load speed of the main content.

FID

FID quantifies the delay between the user's first interaction with a page (e.g., clicking a button) and the browser's response to that interaction. It is a key metric for measuring responsiveness and interactivity.

Load Time

Load time is the total duration from the start of the page load to the completion of all elements on the page. It determines how quickly users can fully interact with the page's content.

CLS

CLS measures the total of all individual layout shift scores for unexpected layout shifts that occur during the entire lifespan of the page. It helps assess the visual stability of a webpage and reduces user frustration from content shifting unexpectedly.
