How can you [measure](https://www.mindstick.com/articles/12961/nonactin-based-biosensors-to-measure-ammonia) [Core Web Vitals](https://www.mindstick.com/blog/304957/the-growing-importance-of-core-web-vitals-for-seo-rankings) using Lighthouse? ## Replies ### Reply by Khushi Singh The open-source tool [Lighthouse](https://www.mindstick.com/articles/43833/google-lighthouse-and-how-is-it-changing-the-way-we-development-and-design-websites) enables users to assess webpage performance and quality through its development by Google. Measurement of [Core Web](https://www.mindstick.com/forum/160558/what-is-scaffolding-in-dot-net-core-web-api) Vitals represents a main capability of this tool because these indicators directly impact user experience. A web page gets assessed through vitals combining Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS) as well as Total Blocking Time (TBT) that acts as a laboratory measurement in place of First Input Delay (FID). **Lighthouse** runs from PageSpeed Insights along with Chrome DevTools and as a command-line interface with Node.js installations. You can find Lighthouse in Chrome by opening the webpage in question then utilizing DevTools while selecting the “Lighthouse” tab followed by choosing the device type between mobile or desktop then hitting the “Generate Report” button. The Core [Web](https://www.mindstick.com/articles/339024/seo-and-web-design-how-to-make-your-site-search-engine-friendly) Vitals measurements become available through the completed report. LCP determines how swiftly users see the largest component on the page and directly affects the way visitors perceive load time. Vision stability assessment through CLS depends upon detecting page layout changes until the page finishes loading. The TBT measure simulates full browser activity while estimating how much time the system takes to process user actions when it has no response distractions. Lighthouse implements simulated laboratory data but maintains its diagnostic value for performance analysis and fix-testing within controlled simulated conditions. The system from Lighthouse presents step-by-step recommendations for users to optimize Core Web Vitals through image compression and Js optimization and blocking resource latency reduction. Developers use these suggestions to optimize their work precisely which leads to better user experience together with improved [SEO](https://www.mindstick.com/articles/338614/why-seo-tools-alone-won-t-save-you-but-smart-strategies-will) rankings. Google Page Experience requirements and high website performance remain achievable through regular Lighthouse audits by developers. --- Original Source: https://www.mindstick.com/forum/161448/how-can-you-measure-core-web-vitals-using-lighthouse Copyright © MindStick Software Pvt.
