Google PageSpeed Insights

Why Use Google PageSpeed Insights?

1. Performance Analysis

Google PageSpeed Insights provides performance scores for mobile devices and desktop computers. The scores are based on several factors, such as page load time, time to interactivity, and the time until the page is fully loaded.

2. Optimisation Recommendations

The tool provides a list of recommendations for improving the page loading speed. Recommendations may include reducing image sizes, optimising JavaScript and CSS code, caching resources, and more.

3. User Experience Measurement

PageSpeed Insights also evaluates the user experience on the page, including the stability of visual content and responsiveness to user interactions.

4. Field Data

In addition to lab analysis, PageSpeed Insights provides field data collected from real users. This data gives an overview of the page’s performance under real-world conditions.

Google PageSpeed Insights in Images:

Google PageSpeed Insights is a free tool offered by Google that analyses the performance of web pages and gives recommendations for improving loading speed.

To use Google PageSpeed Insights, simply enter the URL of the page you wish to analyse into the tool, then click “Analyse”. The tool will generate a report with performance scores and optimisation recommendations.

The scores for mobile devices and desktop computers are calculated slightly differently, due to differences in processing capabilities and network conditions. In general, pages should be optimised to deliver good performance on both types of devices.

You can improve your performance score by following the optimisation recommendations provided by the tool. These recommendations may include reducing image sizes, optimising JavaScript and CSS code, improving resource caching, and other technical improvements.

Field data is performance measurements collected from real users of the page. They give an overview of the page’s performance under real-world conditions, as opposed to ideal lab conditions.

Google PageSpeed Insights and Google Lighthouse are two tools developed by Google that serve to analyse the performance of web pages. However, they focus on slightly different aspects of performance and optimisation.

Google PageSpeed Insights is primarily focused on measuring page loading speed and gives recommendations for optimising it. It provides performance scores for mobile devices and desktop computers, as well as field data based on real user experiences.

Google Lighthouse, on the other hand, offers a more comprehensive evaluation of page quality, taking into account not only performance, but also accessibility, web best practices, SEO, and the quality of progressive web applications. It also provides recommendations for improving the page in each of these areas. Lighthouse can be run directly in the browser through Chrome’s developer tools, or as a browser extension or command-line application.

In short, although both tools overlap, they are best used together to obtain a comprehensive assessment of the quality and performance of your website.
