PageSpeed Insights provides the Core Web Vitals metrics and technical recommendations. Dave’s Core Web Vitals Scorecard adds the missing layer for marketers and website owners by translating those numbers into likely user experience symptoms, identifying the single biggest driver to fix first, and generating a paste-ready summary you can share with a developer or team.
Get your metrics from PageSpeed Insights, then use this scorecard to prioritize and communicate clearly without turning the results into a technical audit or an SEO report.
1) Core Web Vitals inputs
Largest Contentful Paint. Use the mobile value from PageSpeed Insights.
Interaction to Next Paint. Use the mobile value from PageSpeed Insights.
Cumulative Layout Shift. Use the mobile value from PageSpeed Insights.
Tip: run PageSpeed Insights for your home web page (or highest-traffic web page) and copy the mobile values for LCP, INP, and CLS.
2) Context for interpretation
This changes the prioritization guidance and the paste-ready summary.
What this tool does and what it does not do
This tool turns three metrics into a simple experience status, a prioritization view, and common friction symptoms.
It is not a technical audit. Use it to prioritize, then hand it to a developer, theme vendor, or agency if needed.
It focuses on user experience and interaction quality, not search rankings.
