The data will be returned through the PSI report. And suggestions to improve the page will be provided to users by this tool. As of late 2018, PSI is operated by Lighthouse. Therefore, the figures in the PSI report are based on data from the Lighthouse Lab. When scanning the Web, Pagespeed Insights will provide two types of data to users:

The first is the laboratory data (Lab Data) The second is the actual data (Field Data)

Lab Data is collected in a controlled environment. With multiple devices and pre-arranged Internet. Because network and device problems are thoroughly checked. So the returned results will tell the user that the problem is caused entirely by Website performance.

From there they easily find the error and fix it. On the other hand, real data is the data that has been collected through real page loads coming from users. From here, we examine and resolve Page Speed ​​bottlenecks that can occur in practice.

What kind of information does PageSpeed ​​provide about the Website?

How is PageSpeed ​​Insights Score calculated?

As mentioned above. PageSpeed ​​Insights results are provided with the Lighthouse API. Google Pagespeed Insights score is no exception. The most important thing to note is: Lightgouse simulates page loading in a pre-ordered environment:

With mid-range network and mobile devices. Some documents on how to calculate Lighthouse have been released by Google Page Speed. They will help us understand more about the origin of Page Speed ​​Insights ranking.

Lighthouse returns a Performance Score for Websites between 0 and 100. 0 is the lowest score, it only happens when Lighthouse is down. <…>. 100 is the highest that a Website has. It represents that the Web is in the Top 98th percentile (on a scale of 100). Score 50 represents the 75th percentile.

Google Page Speed ​​also clarifies: In the Lighthouse Performance category, only the entry in the Metrics section affects the Page Speed ​​score. With Lighthouse 6 (released in May, 2020), it will be measured by the following 6 metrics:

First Contentful Paint – First content displayedTime to Interactive – Time to interactSpeed ​​Index – Speed ​​Index Page SpeedLargest Contentful Paint – Largest element displayed Total Blocking Time – Total blocking timeCumulative Layout Shift – Cumulative layout changes


Lighthouse will use these metrics to create a Performance Rating table. Depending on the score frame, there will be different colors:

0 to 49 (slow): Red50 to 89 (medium): Orange90 to 100 (fast): Green

If you want to know how the index affects the final score. Then please refer to the detailed score of Google Pagespeed Insights.

How does Pagespeed Insights affect SEO?

Google Page Speed ​​will evaluate a part of the Web’s friendliness through the Google Pagespeed Insights score. In fact, this score really has nothing to do with SEO. However, a high score equates to a better experience for visitors.

Search engines through this index will appreciate the Website. At the same time push the ranking of the Web to the table of results more, higher. Although the Page Speed ​​score does not affect SEO. But if it is high, it will help us get more visits and stay on the Web longer.

In short, Page Speed ​​scores have no direct effect on SEO progress or scores. It also won’t improve or lower your website’s rankings. But a high Pagespeed Insights score will result in a great experience.

How to use Google PageSpeed ​​Insights Report

We already know the PSI, so how do we use the PSI report? To produce PSI Report, visit the link of PSI, enter your URL and wait for the results to display Page Speed. So then what? Of course, we have to check the data and fix the errors that PSI makes to make the Web work better.
