🏁 Step 1: Open Chrome DevTools

The easiest way to run Lighthouse is through Google Chrome.

  1. Open the website you want to test.

  2. Right-click anywhere on the page and select Inspect, or press F12 on your keyboard.

  3. In the top menu bar of the panel that appears, look for the Lighthouse tab. (If you don't see it, click the double arrow >> to find hidden tabs).

⚙️ Step 2: Configure Your Audit

Before you hit the "Analyze" button, you can choose how you want Lighthouse to run:

  • Mode: Navigation (default), Timespan, or Snapshot.

  • Device: Choose Mobile 📱 or Desktop 💻. Google usually prioritizes mobile performance for SEO rankings.

  • Categories: You can select all five or just the ones you are currently focusing on.

📊 Step 3: Run the Report

Click Analyze page load. The tool will refresh your page and run a series of tests. After a few seconds, you'll see a dashboard with scores ranging from 0 to 100.
