Pagespeed Insights score

First Contentful Paint:

Metrics that measures how long it takes the browser to render the first piece of DOM content after a user navigates to your page. Images, non-white canvas elements, and SVGs on your page are considered DOM content; anything inside an iframe isn't included.

Largest Contentful Paint:

The Largest Contentful Paint (LCP) metric reports the render time of the largest image or text block visible within the viewport, relative to when the page first started loading. it marks the point in the page load timeline when the page's main content has likely loaded—a fast LCP helps reassure the user that the page is useful.

Time to Interactive:

The TTI metric measures the time from when the page starts loading to when its main sub-resources have loaded and it is capable of reliably responding to user input quickly.

Total Blocking Time:

The main thread is considered "blocked" any time there's a Long Task—a task that runs on the main thread for more than 50 milliseconds (ms). We say the main thread is "blocked" because the browser cannot interrupt a task that's in progress. So in the event that a user does interact with the page in the middle of a long task, the browser must wait for the task to finish before it can respond.

Cumulative Layout Shift:

Metric that measures the biggest burst of layout shift scores for each unexpected layout shift that occurs over the course of a page's lifetime. Because resources are loaded asynchronously or DOM elements are dynamically added to the page above existing content, unexpected page content migration is common.

Time to First Byte:

TTFB is a metric that measures the time between the request for a resource and when the first byte of a response begins to arrive.

Speed index:

Speed Index measures how quickly content is visually displayed during page load.
