What Is Google Lighthouse?

Developed by Google, Google Lighthouse is an automation tool designed for web developers to measure and enhance their website’s performance. It takes a web address as an input and generates a list of recommendations based on performance, search engine optimization, accessibility, PWA, etc. By using these metrics, you can boost page load performance and make your site faster than ever.

Measuring the efficiency of your website can be challenging. To elevate the performance of your website, you need to understand exactly what you measure. LT Browser now integrates Google Lighthouse! This allows you to measure the performance statistics of your website right away.

How Does This Performance Report Help You?

With the new power-packed and Lighthouse backed performance reports, you will be able to do a lot more than everyday reporting. With LT browser, you can now view the following metrics:

Desktop And Mobile Score

Based on the performance of your website over different browsers, the desktop and mobile scores will be generated. The score is divided into three categories, namely- Poor, Average, and Medium. As the names suggest, they will help define the page speed score of your website.

Performance Metrics

It comprises audits of performance, best practices, SEO, progressive web apps, and more. By analyzing these audits, you would know how well your page performs and make enhancements to those web pages. You can view the performance metrics for both desktop and mobile devices.
