Core Web Vitals

Track LCP, CLS, and INP with real Chrome UX Report field data — the same data Google uses for its page experience ranking signal. Monitor by device type and track improvements over time.

The Reality

Speed Penalties Are Silent Revenue Killers

53%

53% of mobile users abandon sites that take over 3 seconds to load — every millisecond matters.

1%

Every 100ms of latency costs e-commerce sites 1% in conversion rate — speed is literally money.

33%

Only 33% of websites pass all three Core Web Vitals thresholds — most sites are leaving rankings on the table.

Don't let invisible speed issues silently drain your traffic and conversions. Monitor what Google actually measures.

The Problem

Without CWV Monitoring...

You're guessing about page speed instead of measuring what Google actually sees.

Critical

Page Speed Insights is manual

Running PSI one URL at a time doesn't scale. You need site-wide CWV monitoring at the domain level, not per-URL spot checks.

Critical

Lab data ≠ field data

Lighthouse scores don't match real user experience. Only field data from real users counts for Google's ranking signal.

Pain Point

No historical trend tracking

Google's tools show current data only. You can't see if your optimizations actually improved performance over time.
