Clickio Web Vitals Monitoring Metrics

Primary Metrics (taken into account for compliance)

Largest Contentful Paint (LCP) Metrics
  • Largest Contentful Paint (LCP) 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 Compliance, % 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 (<4s), % is a proportion of green (compliant) and yellow (needs improvement) LCP requests to a total number of analyzed LCP requests.
First Input Delay (FID) Metrics
  • First Input Delay (FID) 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 Compliance, % 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 (<300ms), % is a proportion of green (compliant) and yellow (needs improvement) FID requests to a total number of analyzed FID requests.
Cumulative Layout Shift (CLS) Metrics
  • 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 Compliance, % 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 (<0.25), % is a proportion of green (compliant) and yellow (needs improvement) CLS requests to a total number of analyzed ​​CLS requests.
Interaction to Next Paint (INP) Metrics
  • Interaction to Next Paint (INP) evaluates the overall responsiveness of a page to user interactions by observing the time it takes the page to respond to all clicks, taps, and keyboard interactions that occur throughout the duration of a user's visit to the page. The final INP value represents the longest observed interaction excluding outliers.
  • INP Compliance, % is a proportion of the green (compliant) INP requests to a total number of analyzed INP requests. 

  • INP Requests is the number of pageviews with the measured INP.

  • INP (<500ms), % is a proportion of green (compliant) and yellow (needs improvement) INP requests to a total number of analyzed ​​INP requests.

Additional Metrics (not taken into account for compliance)

First Contentful Paint (FCP) Metrics 
  • First Contentful Paint (FCP) 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 Compliance, % 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.

  • FCP (<3s), % is a proportion of green (compliant) and yellow (needs improvement) FCP requests to a total number of analyzed ​​FCP requests.
Time To First Byte (TTFB) Metrics
  • Time to first byte (TTFB) 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 Compliance, % 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.

  • TTFB (<1800ms), % is a proportion of green (compliant) and yellow (needs improvement) TTFB requests to a total number of analyzed ​​TTFB requests.
Other Metrics 

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