Page speed has always been an important aspect of how well a website performs in search engines and how users perceive it to be useful. It can also influence whether or not a person converts or purchases from a website.

We've all done it: abandoned a slow webpage and restarted our search.
Insight into Page Speed
Before we can properly and sustainably optimize a website for page speed, we need to understand what Google (and other search engines) consider when determining your website's Page Speed Insights score. While it is obvious which features are assessed and reported, it is not necessarily clear what those metrics are and what they measure.

That is why we produced this guide: to help you understand the Page Speed Insight data so that your website is more user-friendly and accessible to end users.

Most Contented Paint (LCP)
The largest contentful The Paint indicator is an important parameter in the Page Speed Insights report and will play a role in the May 2021 Google Algorithm Update, which we urge you to read about if you haven't already. Simply put, the most contentful Paint calculates the amount of time it takes to populate and visualize the largest image or text block within the viewport given in your browser. All LCP is based on the moment the website first began loading.

The very first Contentful Paint (FCP)
In general, First Paint refers to the exact second that anything on your browser is rendered. The First Paint is often a header or banner image at the top of the page you're attempting to load, but it could also be the page's background color. 'Painting' a banner picture or page backdrop first gives the impression of a fast-loading page.

However, there is another level to First Paint. First and foremost, use Contentful Paint. First, Contentful Paint (FCP) is significantly more successful at managing page speed. It counts the time it takes for the first piece of genuine content (text, copy, or visual assets) to show up in your browser.

Simply put, FCP is the point at which content that your user can interact with or benefit from is made visible.

Time to Interactive (TTI)
Time to Interactive (TTI) is another page speed measure that is critical to search engines and, maybe more importantly, to users. Time to Interactive indicates (as expected) how long it takes for a web page to become fully interactive.

When it comes to SEO and page speed, the phrase 'interactive' can be very subjective; however, Google defines Time To Internative (TTI) using three criteria:

The website provided and displayed useful information
The majority of all visible page elements have had event handlers correctly registered.
The page now responds to user interactions swiftly and effectively, often within 50 milliseconds.
Simply expressed, Time to Interactive refers to the point at which visitors to your site or web page may view, navigate, and interact without facing any problems or delays.

Index of rapidity
Speed index is a basic notion (which is unusual in the world of SEO, where everything is generally insanely complex). Google defines a site's speed index as the time it takes (in seconds) for the content on your web page or site to become visibly populated.

When calculating the index, Google compares the Speed Index score of a web page (obtained with the Speedline Node.js module) to the HTTP Archive data.

Time spent blocking
This metric shows how long (in seconds) it takes a web page to respond to user interaction. Examples of user input include mouse clicks, keyboard presses, and screen taps.

To compute total blocking time, sum all 'Long Tasks' between the FCP and TTI points. Following that, any task that takes more than 50 milliseconds is classified as a "long task," and the total blocking time (TBT) is determined; for example, a process that takes 70 milliseconds will result in a TBT of 20 milliseconds.

Layout Modifications Added Together (CLS)

CLS will again play an important part in the CWV Algorithm Update in May 2021 (and we encourage you to read more about this in our guide). A layout shift occurs whenever a visible piece moves or switches abruptly from one frame to another.

Have you ever clicked something on a webpage and the entire page (or most of it) moved suddenly? And you wind up clicking on the wrong thing? We have all been there. It's called cumulative layout shift.

Simply put, a cumulative layout shift is the aggregate of all unexpected and sudden layout shifts that occur during a user's sessions while viewing a web page.
