Lighthouse

Definition: A free audit tool from Google that evaluates a website for performance, accessibility, best practices, and SEO, directly in the Chrome browser by pressing F12 → “Lighthouse.”

Everyday analogy: Like a vehicle inspection for your website. It’s performed in a standard environment and provides a report with a list of issues.

How we use it: Lighthouse is an essential tool for every SEO audit. We combine Lighthouse lab metrics with CrUX field data, the lab shows potential, while the field data shows reality.
