Real-user monitoring — the Core Web Vitals your visitors actually feel.
Relvato collects Core Web Vitals from your real visitors — LCP, INP and CLS — and reports the p75 per page and device, so you see the speed your customers actually experience, not just a lab test.
- ✓Real visitors' LCP, INP and CLS — measured right in their browsers
- ✓Plus FCP and TTFB, from a lightweight cookieless beacon
- ✓p75 per page type (home, product, checkout…) and device (mobile/desktop)
- ✓Graded against Google's thresholds: good, needs-improvement, poor
- ✓Regression alerts when a metric drifts past the page's own 28-day baseline
- ✓Each regression correlated with the change that shipped around then
Lab runs are stable but synthetic; Google ranks on field data from real Chrome users, and INP only truly exists in a real browser. Real-user monitoring surfaces the slowdown your visitors feel — and catches a regression on one template that a homepage lab test never touches.
Works on any site — from WordPress to AI-built sites.
New to Core Web Vitals, or unsure how lab tests and real-user data differ? Our guide breaks down Core Web Vitals vs RUM — what each measures, when to use it, and which one Google ranks on.
- A tiny, cookieless beacon collects LCP/INP/CLS from about 15% of real page views — no page URLs, no personal data.
- Relvato aggregates the p75 per page-template and device over a rolling window, once there are enough samples to trust.
- Alerts on the CWV ‘poor’ band and on a regression versus the page’s own baseline — the field signal Google’s ranking uses.
What are LCP, INP and CLS?
They're Google's Core Web Vitals. LCP (Largest Contentful Paint) is how quickly the main content appears; INP (Interaction to Next Paint) is how quickly the page responds to a tap or click; CLS (Cumulative Layout Shift) is how much the layout jumps around as it loads. Relvato reports the p75 of each from your real visitors and grades it against Google's thresholds.
Is it privacy-friendly?
Yes — the beacon is cookieless, sends no page URLs or personal data, and samples about 15% of views. On by default in the plugin; one toggle to turn it off.
How is it different from the lab check?
The lab run is a controlled synthetic measurement; real-user monitoring is field data from your actual visitors — what Google’s ranking is based on.
