Core Web Vitals

Last updated: 2026-03-296 min read

This guide covers Core Web Vitals. How LCP, INP, and CLS show up in PageReflect—and how lab snapshots relate to Google’s Core Web Vitals story.

PageReflect includes a mobile Lighthouse lab run for each audit. When it succeeds, LCP, CLS, and interactivity signals (INP where available, otherwise TBT as a lab proxy) appear in your report and feed the performance narrative. Lab data is a controlled snapshot, not a guarantee of what every visitor experiences.

Sections below are outlines—we will deepen them over time. For live output, run an audit from your dashboard or try preview.
