Site Performance (CWV)

Lighthouse performance score + Core Web Vitals style metrics (LCP, CLS, TBT, FCP) and top opportunities.

Measure how fast the page feels for users — lab Core Web Vitals (LCP, CLS, TBT) that affect ranking and bounce rate.

What you get

Performance score 0–100, metric-by-metric verdict with why, and prioritized fixes (images, JS, TTFB…).
