Clickio Web Vitals Monitoring Metrics

Largest Contentful Paint (LCP), sec measures how long it takes for a page’s main block of content to load. Usually, the main block of content is an image, a video, or a big block of text. A site provides a good user experience if its main block of content loads within 2.5 seconds.
LCP Green, % is a proportion of green (compliant) LCP requests to a total number of analyzed LCP requests.
LCP Requests is the number of pageviews with the measured LCP.
LCP Green+Yellow, % is a proportion of green (compliant) and yellow (needs improvement) LCP requests to a total number of analyzed LCP requests

First Input Delay (FID), sec quantifies the period of time between the moment when the user first interacts with a web page (e.g., clicking on a link or a button) and the moment when the site actually responds to that interaction (e.g., opening the link). To provide a good user experience, sites should have FID lower than 100 milliseconds.
FID Green, % is a proportion of the green (compliant) FID requests to a total number of analyzed FID requests.
FID Requests is the number of pageviews with the measured FID.
FID Green+Yellow, % is a proportion of green (compliant) and yellow (needs improvement) FID requests to a total number of analyzed FID requests

Cumulative Layout Shift (CLS) quantifies the amount of unexpected layout shifts that occur while the webpage is loading (e.g., text that moves up and down the page, or a link that changes its position while the user is trying to click on it). According to Google a site provides a good user experience if its CLS is lower than 0.1.
CLS Green, % is a proportion of the green (compliant) CLS requests to a total number of analyzed CLS requests.
CLS Requests is the number of pageviews with the measured CLS.
CLS Green+Yellow, % is a proportion of green (compliant) and yellow (needs improvement) CLS requests to a total number of analyzed CLS requests

First Contentful Paint (FCP), sec quantifies how long it takes the browser to render the first piece of DOM (Document Object Model) content after a user navigates to a page.
FCP Green, % is a proportion of the green (compliant) FCP requests to a total number of analyzed FCP requests.
FCP Requests is the number of pageviews with the measured FCP.

Time to first byte (TTFB), msec determines the responsiveness of a web server. It measures the amount of time between creating a connection to the server and downloading a web page's contents.
TTFB Green, % is a proportion of the green (compliant) TTFB requests to a total number of analyzed TTFB requests.
TTFB Requests is the number of pageviews with the measured TTFB.

Requests are the number of pages analyzed to estimate CWV metrics.
