## AI summary

Use this page when an agency, freelancer, or consultant needs a simple Core Web Vitals report structure for clients with field/lab labels, proof, owner, first fix, and export/share steps.

## Key caveats

- Client reports should keep CrUX field data, Lighthouse lab data, Search Console groups, and unavailable data visibly separate.
- Do not promise ranking, conversion, revenue, or passing Core Web Vitals from one report.
- Use lab reruns for immediate before-after checks, then wait for CrUX field data before claiming a field issue recovered.
- Public share links and exports should include only report evidence that is safe to show to the recipient.

## Client report structure

- Executive verdict: one sentence describing the current state and the affected metric.
- Source labels: name which facts came from CrUX field data, Lighthouse lab diagnostics, Search Console URL groups, or unavailable data.
- Metric snapshot: show LCP, INP, CLS, and TTFB only when the source exists and the metric is relevant.
- Proof: show the likely cause, affected element or resource class, and any before-after comparison that exists.
- First fix: name the owner, first safe action, acceptance check, and rerun instruction.
- Caveats: say what the report cannot prove yet, especially after same-day changes.
- Share/export: send a public share link or Markdown/PDF export when the client needs the report outside the app.

## Sample report section

- Verdict: Mobile LCP is poor in CrUX field data, and the lab run points to the hero image plus blocking CSS as the first place to inspect.
- Source labels: CrUX field data is delayed real Chrome-user evidence; Lighthouse lab data is the immediate diagnostic run for the exact URL.
- First fix: Developer or CMS owner should resize and prioritize the hero image, then rerun the same mobile lab check.
- Acceptance check: Lab LCP should improve on the same URL and device profile; CrUX field data should be reviewed again after the next field-data window.
