A Core Web Vitals client report clients can actually act on.
Use one source-labeled structure for the verdict, proof, first fix, owner, acceptance check, and share/export step. It keeps the report useful without turning it into a raw audit dump.
No signup needed. Takes about 30 seconds.
Sample report
Short enough to read, specific enough to assign.
01
Executive verdict
Mobile LCP is poor in CrUX field data. The first lab diagnostic points to the hero image and blocking CSS.
02
Source labels
CrUX field data: delayed real Chrome-user evidence. Lighthouse lab data: immediate diagnostic for the exact URL.
03
Proof
The main image is the likely LCP element, and render-blocking CSS delays the first meaningful view.
Template structure
The report should answer what happened and who acts next.
Each section earns its place by making the next client, developer, marketer, or CMS-owner decision easier.
Executive verdict
Mobile LCP is poor in CrUX field data. The first lab diagnostic points to the hero image and blocking CSS.
Source labels
CrUX field data: delayed real Chrome-user evidence. Lighthouse lab data: immediate diagnostic for the exact URL.
Proof
The main image is the likely LCP element, and render-blocking CSS delays the first meaningful view.
First fix
Owner: developer or CMS owner. 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. Review CrUX again after the next field-data window.
Share and export
Pick the format that matches the handoff.
Reports are useful when they move cleanly into the place the work happens: a client email, ticket, pull request, or stakeholder review.
Share link
Send a safe public report URL when the client only needs to read the result.
Markdown export
Use plain text for tickets, pull requests, agency task lists, and coding-agent handoffs.
PDF export
Use a compact report artifact for stakeholder reviews and recurring client updates.
Client-safe caveats
Clear caveats make the report easier to trust.
A good report is specific about what it shows and careful about what it cannot prove yet.
Keep CrUX field data, Lighthouse lab data, Search Console URL groups, and unavailable data visibly separate.
Do not promise rankings, conversions, revenue, or passing Core Web Vitals from one report.
Use lab reruns for same-day verification and field data for slower-moving real-user recovery.
Only share evidence that is safe for the client or teammate receiving the report.
Use nimo
Run, share, export, then verify.
nimo turns the audit into a source-labeled report with the first fix and verification step already attached.
Share
Create a public report link for the client or teammate.
Export
Use Markdown for tickets or PDF for stakeholder review.
Handoff
Copy the first-fix prompt into a ticket or coding-agent task.
Sources checked
Use source labels in the report itself.
