LLighthouse

Lighthouse is an open-source automation tool developed by Google that audits the quality of web pages. It runs a series of tests against a URL and generates a report showing how well your site performs across key metrics. You can run Lighthouse directly in Chrome DevTools, from the command line, or as part of your continuous integration pipeline.

For businesses, Lighthouse matters because it directly impacts user experience and search rankings. The tool measures Core Web Vitals (loading speed, interactivity, and visual stability), accessibility compliance, SEO best practices, and progressive web app capabilities. A site that scores poorly on Lighthouse typically suffers from slow load times, poor mobile usability, and reduced search visibility — all of which hurt conversion rates and customer satisfaction.

Lighthouse works by simulating real-world conditions, throttling network and CPU performance to reflect typical mobile devices, and then measuring how your site responds. It identifies specific issues — from unoptimised images to render-blocking resources — and provides actionable recommendations for improvement. The scoring system (0–100) gives you a clear baseline and helps track progress over time.

At Dino Media, we use Lighthouse throughout our development process to ensure sites we build meet performance standards before launch and remain optimised afterwards. We analyse Lighthouse reports to prioritise improvements, focusing on changes that deliver real business impact. Whether we're building a new website, optimising an existing one, or managing your hosting infrastructure, Lighthouse findings inform our technical decisions and help us deliver faster, more accessible experiences for your users.
