Core Web Vitals

Definition
Core Web Vitals are Google's three page-experience metrics — LCP (loading), INP (responsiveness), and CLS (visual stability). Quri pulls your site's real-user CrUX field data and Lighthouse lab scores on a schedule, bands each metric good, needs-improvement, or poor, and alerts you when one regresses, because slow pages quietly cost you conversions and ad quality.
How to do this in Quri
- Open Audit then Site Speed in /app to see your latest LCP, INP, CLS, and Lighthouse scores.
- Read each metric card to see its p75 value and whether it is good, needs-improvement, or poor.
- Tap Re-measure to schedule a fresh reading when the last one looks stale.
- Ask the assistant 'how fast is my site?' to get the same numbers in chat.
Frequently asked
- What is the difference between field and lab data?
- Field data (CrUX) is what real visitors actually experienced over the last 28 days; lab data (Lighthouse) is a single controlled test run. Quri shows both and alerts you on the real-user field-data regression, since that is what your customers feel.
- Why does page speed matter for an online seller?
- Slow pages lose buyers before they convert and drag down ad quality scores, so you pay more per click. Watching Core Web Vitals catches a regression early — before it quietly costs you sales — instead of after the month-end numbers slip.
