How to read this data

Scores (Performance / Accessibility / Best Practices / SEO) update on every run. Deploy a fix → run this dashboard → see new numbers within minutes. Immediate feedback.

Real users (LCP / CLS / INP) are real visitor data collected automatically by Google. Uses a 28-day rolling window: each day, 1 new day is added and 1 old day is dropped. So improvements show up gradually, not instantly.

Day 0
Deploy a fix. Scores reflect it immediately.
Day 7
~25% of the effect visible in Real users
Day 14
~50% of the effect in Real users
Day 28
Full effect captured, new stable baseline
Quote from official Google documentation:
"The data in the Chrome UX Report is a 28-day rolling average of aggregated metrics, meaning that the data presented at any given time is actually data for the past 28 days aggregated together."
Source: Chrome UX Report API documentation (developer.chrome.com)

This is not our rule — it is Google CrUX (Chrome User Experience Report) methodology. Also see: CrUX History API — confirms "calculated from the previous 28 days as a rolling window".

Google CWV thresholds: Good (PSI ≥90, LCP ≤2.5s, CLS ≤0.1, INP ≤200ms) Needs Improvement Poor (PSI <50, LCP >4s, CLS >0.25, INP >500ms)

Real users history (CrUX, 25 weekly p75 — latest end 2026-06-27)

Each point = p75 of a 28-day rolling window. 5 lines per chart: Origin (dashed black, whole-site baseline) + each tracked URL. Click a legend item to hide/show that line.

Forced reflow
▸
A forced reflow occurs when JavaScript queries geometric properties (such as offsetWidth) after styles have been invalidated by a change to the DOM state. This can result in poor performance. Learn more about [forced reflows](https://developer.chrome.com/docs/performance/insights/forced-reflow) and possible mitigations.
