As a website owner, maximizing your site’s Search Engine Optimization (SEO), accessibility, and performance is of utmost importance. However, to address these factors as efficiently as possible, care must be taken to use the right tools and techniques. One of the most innovative solutions today is that you can take advantage of what is called Google Lighthouse.
In this article, we will introduce you to Google Lighthouse and how it works. Then we will explain how you can use it to improve your website.
Know What is Google Lighthouse
Lighthouse is an automated open source tool to improve the quality of web pages. Lighthouse is used as a measurement and auditing tool for website quality performance, accessibility, progressive web applications, and more.
Who is Suitable to Use Google Lighthouse?
Lighthouse Tools aren’t just for developers. This tool is suitable for any site owner who is interested in learning more about website performance and the concrete steps to run it.
There are several different ways to use this tool. You can run it via:
- Chrome Developer Tools
- Chrome Extension
- A Node module
- Web User Interface (UI)
Important note, Lighthouse is currently mainly focuses on Progressive Web App features, such as Add to Homescreen and offline support. However, the underlying goal of this project is to provide an audit of all aspects of web application quality.
The main focus of the Lighthouse audit is Google Core Web Data. If you’re not familiar, this is an important metric that Google uses to measure web page speed and overall User Experience (UX). They consist of:
- FID = First Input Delay.
- CLS = Cumulative Layout Shift, and
- LCP = Largest Contentful Paint.
In other words, using Lighthouse helps you view your website the same way Google does. You can use the actionable insights it provides to optimize your pages for better search engine ranking results.
The Lighthouse report is divided into five categories:
- Best Practice
- Progressive web app
Lighthouse also uses a 1 to 100 rating system and tests simulated 3G connection sites. However, scores may vary from time to time as Google updates its ranking criteria frequently. Therefore, you can still keep up with any Lighthouse updates.
Moreover, although it is somewhat similar to PageSpeed Insights, Lighthouse is not the same. Lighthouse offers a more holistic picture than just page performance (as does PageSpeed Insights)
