Google Page Experience with Page-Speed insight [May 2021 Update]


Google search engine or more commonly known as Google, is a household name that everyone knows about. It’s the most used search engine in the world. In addition, google processes more than 5 billion searches every day. When you start searching into, Google. It goes through thousands or sometimes millions of indexed web pages, just to bring you the best and relevant information.  

This all possible due to an advanced learning system call Rank brain, which was came out back in 2015. But recently, on 10 November 2020, Google Search Central Blog announced a new update. Coming to the Google search engine Algorithm, coming up in May 2021. This new update has boiled down to the Algorithm now taking Page Experience in mind while ranking a page. Other than Page Experience, this Update also introduces new Web Core Vitals; Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).   

Now let’s talk more in-depth about the Page Experience and how it factors into the overall Algorithm. 

What is Page Experience: 

Simply speaking, Page Experience dictates the experience of the visitor of your website, Webpage, or blog. However, this update takes into consideration six Matrices; First Contentful Paint, Time to Interactive, Speed Index, Total blocking Time, Largest Contentful Paint. And Cumulative Layout Shift loading speed, interactivity, and visual stability. While also including the old ones like Mobile Friendly, Safe Browsing, HTTPS, and No Intrusive Interstitials. 

First Content Print (FCP) 

First Content Print (FCP), measures how long it takes for your page to load the first piece of content. Which can be an image, white page, element, or SVGs on your page. Another name for these would be DOM content. FCP scores your web page, by comparing your page’s FCP time with other web page’s dates in its HTTP archives. 

Time to Interactive (TTI) 

Time to Interactive (TTI), measures Page Load Speed in each aspect of the web page. Improving Time to interactive (TTI) is necessary as it may cause a frustrating user experience. As the Web Page would seem to load. But when the user will try to interact with it, nothing will happen. On the other hand, the web page would consider “loaded” after it displays necessary content. Event handlers are register and the page responds to user interaction within 50 milliseconds.   

Largest Content Print (LCP) 

Largest Content Print (LCP), measures the time that your web page takes to load the main content of your page. This approximate time should less than 2.5 seconds, which will consider being the very best. Largest Content Print (LCP) is obtain through your browser support which come in Chrome 77. As the Largest Content Print (LCP) date from Chrome’s tracing tool by Lighthouse. 

Speed Index (SI) 

Speed Index (SI) measures how quickly your web page loads its content. First capturing a video of the page loading in the browser and then computes the visual progression between the frames. It uses the Speedline Node.js module to generate the speed index score. 

Total Blocking Time (TBT) 

Total Blocking Time (TBT), measures the time your page un-interactable, such as mouse clicks, screen taps, or keyboard presses. The total time is the sum of blocking time between FCP and TTI. As any task which takes more than 50 ms will be considered a long task. Your web page Total Blocking Time (TBT) will compare to with Total Blocking Time (TBT). Of other 10,000 web pages loaded. 

Cumulative Layout Shift (CLS) 

Cumulative Layout Shift (CLS), measures the unexpected movement of your page’s content/ elements. This usually occurs when the contents of the elements of the page appear asynchronously. Or when DOM elements are adding to the page’s existing content. Cumulative Layout Shift (CLS) calculates score by the sum of total unexpected layout shift that may occur. A layout shift is any element or content that changes its position from one “Render frame” to the next. 

Google Page Speed insight (PSI): 

Google Page Speed insight (PSI), also known as Google Speed Insight Tool. Summarizes and reports on the performance of your web page on two different platforms; phone and desktop. This report can be you to find out a failing audit which many need further improvement and explaining its components.  Google Page Speed insight (PSI) provides bot Lab data and Field data. Which in Conclusion, can make the task of debugging performance issues quick and easy. As it collects the given data in a controlled environment. 


Lighthouse is an open-source and automatic tool that acts as the key center of the Google Speed Insight tool. By helping you to improve the quality of web pages. You run any web page of your website through it and it will give you an overview. Of performance, accessibility, progressive web apps, SEO, and more.  

You can manfully run the Lighthouse from Chrome Dev-Tools through the command line, or as a Node module. Lighthouse will take the given URL and run a series of audits against the web page. Then generates a complete comprehensive report. Which you can use to find all the failing audits as an indicator on how to improve your web page. In addition, each audit comes with explanation and how it matters and how fixing it can improve your site’s Page Experience. 


Whether you are at peace with the new update. Or finding it hard to maintain your website according to it, it’s here to stay. Page Experience will now act as one of the key factors. That determine your web page’s ranking in the Google Search Engine results. One of the easiest ways to take help from the Google Speed Insight tool.   

Google Speed Insight tool can help you by providing you a complete Diagnostics and data to determine your Page Experience. It also helps you by informing you where the trouble arises. And how you can improve it for better user experience and Google Search Engine Rankings.
