Each report provided by this tool has five parts: 

  1. Performance
  2. Accessibility
  3. Best Practices
  4. SEO
  5. Progressive Web App

Each of these sections gives you a score from zero to one hundred for reviewing web pages, so you can understand your strengths or weaknesses in each section. Google Lighthouse first examines each section and gives you a score. Google Lighthouse has a feature to click on the desired section for a better and more accurate analysis of your page and see more details. After analyzing and fixing the weaknesses of the website, you can re-analyze your page with this tool and watch the process of improving your website.

Speed ​​is one of the basic criteria

In fact, Google Lighthouse metrics help you understand how fast a website loads and how long it takes for a user to interact with the website. Note that website loading speed is very important in how users interact with your website. To better understand this issue, consider the following:

  • Many users say that the worst part of the UI experience is the long wait for the website pages to load.
  • On average, it takes about 15 seconds to load most landing pages on a mobile phone.
  • On average, 70% of users spend their time on websites with a loading speed of more than five seconds.
  • By increasing every second of the webpage load time, the user interaction rate decreases by seven percent.

The statistics you see are a huge part of the UI experience. With the help of the Google Lighthouse tool, you can understand the performance and quality of your website. Also, according to the information obtained by using this tool, you can easily improve the status of your website.

How Google Lighthouse works

You might think that you can simply enter the website address in the browser search bar and then find out how fast a website is loading. But website users live in different areas and have access to other internet ISPs; even the type of search and how users use them may differ. Although most website traffic is usually from mobile devices, most users do not have access to the fourth-generation (4G) and fifth-generation (5G) Internet. For this reason, Google lighthouse performs a simulation and measures the website’s loading speed with a third-generation (3G) Internet.

You may now be wondering why Google is doing this. Almost every website loads with very high-speed fourth and fifth-generation internet. But most users do not have access to such high-speed internet. For this reason, Google considers the majority of users and tests websites with a three-generation Internet speed. Since Google has a similar algorithm that scans such websites, you should check your website in the same way. Google lighthouse tools will help you to do this.

PageSpeed ​​Insights vs Google Lighthouse

The PageSpeed ​​Insight tool focuses only on the performance of your web pages. Still, as mentioned, the Google lighthouse tool has the ability to analyze performance, accessibility, best practices, SEO, and advanced web applications. Although the Google lighthouse tool analyzes the website more accurately and completely, what is the purpose of the PageSpeed ​​Insights tool?

In fact, PageSpeed ​​Insights scans the website using real-world data, while the Google lighthouse tool scans the website based on a comprehensive scan and does not necessarily use real-world data to analyze the site. Therefore, it can be said that the PageSpeed ​​Insights tool is more suitable for checking the website’s performance.
