Speed is one of the basic criteria
In fact, Google Lighthouse metrics help you understand how fast a site loads and how long it takes for a user to interact with the site. Note that site loading speed is very important in how users interact with your site. In the course of speeding up the website, we have fully and accurately explained how to improve these items. 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 site 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 sites with a loading speed of more than five seconds.
- By increasing every second of the page 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 get a good understanding of the performance and quality of your site. Also, according to the information obtained by using this tool, you can easily improve the status of your site.
How Google Lighthouse works
You might think that you can simply enter the site address in the browser search bar and then find out how fast a site is loading. But website users live in different areas and have access to different internet sites, even the type of search and the way users use them may be different. Although most site 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 loading speed of the site with a third-generation (3G) Internet.
You may now be wondering why Google is doing this. Almost every site 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 sites with a three-generation Internet speed. Since Google has a similar algorithm that scans such sites, you should check your site in the same way. Google lighthouse tools will help you to do this.
The difference between PageSpeed Insights and Google Lighthouse
The PageSpeed Insight tool focuses only on the performance of site pages, but 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 site more accurately and completely, what is the purpose of the PageSpeed Insights tool?
In fact, PageSpeed Insights scans the site using real-world data, while the Google lighthouse tool scans the site 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 performance of the site.
