The values ​​are chosen to provide a balanced representation of the user's perception of performance. The weightings have changed over time, as the Lighthouse team regularly conducts research and gathers feedback to understand what has the greatest impact on user-perceived performance; The history of these changes can be seen on GitHub. If you want to know how your site is doing compared to other websites in terms of real user data, you can use our PageSpeed ​​test . And now, how can we use it? It's very simple! ADVERTISEMENT It's essentially the same as Lighthouse.

Page Speed ​​Insights While the report is generated, the tool does two things: First, it collects "field data" from the web page in CrUX, that is, the Chrome User Experience Report. Second measures page performance using the Lighthouse API. Calculates the charging rate in a controlled and simulated environment: mid-tier devices and mobile networks. Therefore, this is known as "laboratory data."



After a few seconds of analysis time, you will see a report showing the overall performance score along with a breakdown of the different categories. After reviewing the report, eliminate variables that hinder speed and lower the rankings. Page Speed ​​Insights This is an example made for the Rock Content blog page The generated report is divided into several sections: ADVERTISEMENT Performance Score – The overall score. Field Data – Real-world data from Google, if available. Source Summary – A review of Core Web Vitals. Lab Data – The metrics calculated from Lighthouse. Opportunities – Tips to help the page load faster. Diagnostics – Learn more about app performance.
