Google PageSpeed Insights is a free and powerful tool based on analyzed technical data: laboratory data, and field data. Explanations on how it works, its advantages and the corrections to be made to your site. PageSpeed Insights, also known as PSI, is a performance testing tool offered by Google. The tool, for example, analyzes a URL of your web page and provides a precise report on the points to improve to optimize the loading speed of this same page. Google PageSpeed Insights performs an analysis of the page data in order to render a detailed report.
It gives a score ranging from 0 to 100: from 0 to 49, the score is red; from 50 to 89, the score is orange; and from 90 to 100, the score is green. google pagespeed insights tricolor barometer It also provides statistical data and web Cambodia Email Address performance data. To give a performance score, it takes into account different statistics and laboratory data that are part of the Core Web Vitals. Indeed, the tool analyzes: First Contentful Paint (FCP), the First Input Delay (FID), Largest Contentful Paint (LCP), as well as the Cumulative Layout Shift (CLS). This is the set of Core Web Vitals, in French, the Essential Web Signals.
What is PageSpeed Insights?
The FCP Expressed in seconds, it symbolizes the time elapsed between the start of loading the page and the moment when the first element appears on the page on the screen. The FCP must be less than 1.8 seconds and especially not exceed 3 seconds. The FID The First Input Delay measures the response time of the page between the moment when the Internet user interacts for the first time on the analyzed page and the moment when the page responds to his request. To be efficient, the time must be less than 100 ms. LCP Also expressed in seconds, it measures the time required for the page to load and therefore its performance for loading the main elements of the page. The faster it is, the better.
This score must be less than 2.5 seconds to be effective and must not exceed 4 seconds. The CLS The Cumulative Layout Shift, on the other hand, measures the visual stability of the analyzed page. The CLS score is bad when you click on a link and a block appears (pop-up window, screen shift, annoying advertisement, etc.). This type of block often causes frustration for the Internet user. If the score is high, it means that the phenomenon occurs too often. This score must then be less than 0.1 and not exceed 0.25. What other data is PageSpeed Insights collected?
PageSpeed Insights and Core Web Vitals
Google PageSpeed Insights also takes into account performance statistics (from the Lighthouse tool) and field data such as: the interaction time (Time to Interactive). It is decisive for the user and his experience, it is considered good when it does not exceed 50 milliseconds; the page display speed (Speed Index). It is a benchmark indicator for estimating good user experience and web performance. The faster it is, the better it is for the Internet user. It is considered fast if it is between 0 and 3.4 seconds; the blocking time (Total Blocking Time, TBT). It measures the time between the FCP and the interaction time (TTI). Concretely, it is determined by the execution time of a task: if it is too long, this time will be long (above 50 ms); if it is executed quickly, the time will be better (below 50 ms).
Finally, at the bottom of the page, the tool provides opportunities for areas for improvement to optimize the overall loading speed of the page. google pagespeed insights tips for optimizing website Since PageSpeed Insights is operated by Google, the world’s largest search engine, it’s obvious that the advertised score has an impact on SEO and your page’s ranking in the search results ( SERP ). It is therefore not to be neglected or ignored but indeed to be taken into account if you want to optimize the loading speed. However, this does not guarantee to get a top spot in the SERP because SEO is not based solely, and fortunately, on this score alone.
