Introduction

Why Lighthouse is essential for your website

A fast and accessible website is crucial for an optimal user experience and strong search engine rankings. Lighthouse is a powerful open-source tool from Google that helps analyze and improve web performance, accessibility, and SEO. In this blog, we explain how Lighthouse works and how to use it effectively to optimize your website.

Common issues Lighthouse addresses

Many websites suffer from long load times, poor mobile performance, and inaccessible content. Lighthouse helps identify these issues by running detailed audits across five key areas: performance, accessibility, best practices, SEO, and progressive web apps (PWA). With a Lighthouse analysis, developers can immediately map out improvements and enhance the user experience.
