TL;DR

Lighthouse is the audit engine built into Chrome that Google uses to score page experience. This tool runs it against your URL through the official PageSpeed Insights API and shows the four category scores plus the specific fixes that would move them most. Mobile performance is the score that affects rankings.

How it works

How to read your Lighthouse report

Scores run 0–100. Anything at 90 or above is good, 50–89 needs work, and below 50 is poor. Performance is the volatile one, it depends on network conditions, so run it a couple of times and look at the trend rather than a single number.

1

Paste any public URL

Your homepage, a landing page, or a competitor's site. It just needs to be reachable without a login.

2

Pick mobile or desktop

Mobile is throttled and stricter, it's the one Google uses for ranking, so start there.

3

Wait about 20 seconds

Google loads the page in a real headless Chrome instance and measures it. No estimates.

4

Fix the top three

Scores move fastest when you address the highest-impact opportunities first, not all of them.
