How to audit a website’s performance

Page Performance


Install the Lighthouse CLI for full control over your audit

$ npm install -g lighthouse

By default, Lighthouse throttles your connection and emulates an older mobile device. If you’re auditing a site that’s primarily used on desktop, pass the --disable-network-throttling and --disable-device-emulation arguments.

$ lighthouse --disable-network-throttling --disable-device-emulation --output html --output-path ./report.html
