How To Use Google Lighthouse to Improve Your Site Speed?

A free tool meant to enhance the performance of websites is Google Lighthouse. So anybody may use it on any website since the programme is free and open-source. The programme performs an accessibility and search engine optimization (SEO) audit of your website, concentrating on the most important aspects. There are several digital marketing institute which provide various courses which can help you to get better knowledge on this subject.


Do You Know Your Web Vitals?

Google's Core Web Vitals are a set of metrics that are used to evaluate the speed and usability of web pages and other digital experiences, according to the company. The Core Web Vitals algorithm update, which was introduced by Google in 2021 and examines a website's Core Web Vitals indicators, is a part of the Google Search Engine Optimization programme. Providing a positive user experience and achieving a high Google ranking have become more important KPIs for website owners.


Three of the most important Core Web Vitals are as follows:


  • The time it takes for the most material to load above the fold, as measured by the Largest Contentful Paint (LCP). With this comprehensive guide, you can learn more about LCP.
  • When a user interacts with a page, First Input Delay (FID) is measured. See our FID tutorial.
  • The amount of material that shifts as the page loads is known as the cumulative layout shift (CLS). Find out more about CLS by visiting this page.


Things to Look for Using Google Lighthouse


Google Lighthouse may be used to track your website's core metrics. With this tool, you can see how well your site is optimised for the most common devices and internet connections. However, you may instruct the programme to simulate a particular device or connection for the sake of your experiments. By analysing the findings, you'll be able to determine which parts of the page load process require improvement in order to provide your visitors an enjoyable experience and create brand awareness.
