Site Performance (CWV)
Lighthouse performance score + Core Web Vitals style metrics (LCP, CLS, TBT, FCP) and top opportunities.
What it’s for
Measure how fast the page feels for users — lab Core Web Vitals (LCP, CLS, TBT) that affect ranking and bounce rate.
How it works
Queued Lighthouse performance run in headless Chromium. We extract LCP/FCP/CLS/TBT/Speed Index/TTI, score them, and list the biggest savings opportunities.
What you get
Performance score 0–100, metric-by-metric verdict with why, and prioritized fixes (images, JS, TTFB…).

- Performance score
- LCP
- CLS
- TBT / INP proxy
