The benchmarks below are a starting point grounded in industry standards. Adjust any **Good** or **Bad** threshold to match your business and **save it for your company** in **Settings → Dashboard Settings → Sensitivity**. ## How sentiment powers triage Sentiment turns the dashboard into a focus list. Every KPI is sorted into one of three states you can filter on: * **Performing** - comfortably inside the good band. * **Needs Attention** - has breached the band you set. This is where to act. * **Stable** - within range, or an informational card with no good/bad direction. Any KPI that has not met its sentiment band is flagged **Needs Attention**, so you go straight to the handful of cards that need action instead of scanning hundreds of charts. | Card | Direction | Good | Bad | Unit | | --------------------------------------------------------------------------------------------------------------------- | ---------------- | ---- | ---- | ------------ | | [Click Responsiveness](/nerve-centre/kpi-cards/website-performance/click-responsiveness) | Lower is better | 200 | 500 | duration\_ms | | [Desktop Speed Pass Rate](/nerve-centre/kpi-cards/website-performance/desktop-speed-pass-rate) | Higher is better | 75 | 50 | % | | [First Content Over Time](/nerve-centre/kpi-cards/website-performance/first-content-over-time) | Lower is better | 1800 | 3000 | duration\_ms | | [First Content Visible](/nerve-centre/kpi-cards/website-performance/first-content-visible) | Lower is better | 1800 | 3000 | duration\_ms | | [Lab Layout Stability](/nerve-centre/kpi-cards/website-performance/lab-layout-stability) | Lower is better | 0.1 | 0.25 | Number | | [Lab Load Speed](/nerve-centre/kpi-cards/website-performance/lab-load-speed) | Lower is better | 2500 | 4000 | duration\_ms | | [Layout Stability](/nerve-centre/kpi-cards/website-performance/layout-stability) | Lower is better | 0.1 | 0.25 | Number | | [Layout Stability Over Time](/nerve-centre/kpi-cards/website-performance/layout-stability-over-time) | Lower is better | 0.1 | 0.25 | Number | | [Layout Stability: Mobile vs Desktop](/nerve-centre/kpi-cards/website-performance/layout-stability-mobile-vs-desktop) | Lower is better | 0.1 | 0.25 | Number | | [Load Speed Over Time](/nerve-centre/kpi-cards/website-performance/load-speed-over-time) | Lower is better | 2500 | 4000 | duration\_ms | | [Load Speed: Mobile vs Desktop](/nerve-centre/kpi-cards/website-performance/load-speed-mobile-vs-desktop) | Lower is better | 2500 | 4000 | duration\_ms | | [Mobile Speed Pass Rate](/nerve-centre/kpi-cards/website-performance/mobile-speed-pass-rate) | Higher is better | 75 | 50 | % | | [Page Freeze Time](/nerve-centre/kpi-cards/website-performance/page-freeze-time) | Lower is better | 200 | 600 | duration\_ms | | [Page Load Speed](/nerve-centre/kpi-cards/website-performance/page-load-speed) | Lower is better | 2500 | 4000 | duration\_ms | | [Performance Score](/nerve-centre/kpi-cards/website-performance/performance-score) | Higher is better | 90 | 50 | score | | [Performance Score Over Time](/nerve-centre/kpi-cards/website-performance/performance-score-over-time) | Higher is better | 90 | 50 | score | | [Performance Score Summary](/nerve-centre/kpi-cards/website-performance/performance-score-summary) | Higher is better | 90 | 50 | score | | [Responsiveness Over Time](/nerve-centre/kpi-cards/website-performance/responsiveness-over-time) | Lower is better | 200 | 500 | duration\_ms | | [Responsiveness: Mobile vs Desktop](/nerve-centre/kpi-cards/website-performance/responsiveness-mobile-vs-desktop) | Lower is better | 200 | 500 | duration\_ms | | [Server Response Time](/nerve-centre/kpi-cards/website-performance/server-response-time) | Lower is better | 800 | 1800 | duration\_ms | | [Server Response Time](/nerve-centre/kpi-cards/website-performance/server-response-time) | Lower is better | 800 | 1800 | duration\_ms | | [Server Speed Over Time](/nerve-centre/kpi-cards/website-performance/server-speed-over-time) | Lower is better | 800 | 1800 | duration\_ms | | [Server Speed: Mobile vs Desktop](/nerve-centre/kpi-cards/website-performance/server-speed-mobile-vs-desktop) | Lower is better | 800 | 1800 | duration\_ms | | [Speed Index](/nerve-centre/kpi-cards/website-performance/speed-index) | Lower is better | 3400 | 5800 | duration\_ms | | [Speed Test Pass Rate](/nerve-centre/kpi-cards/website-performance/speed-test-pass-rate) | Higher is better | 75 | 50 | % | | [Total Page Weight](/nerve-centre/kpi-cards/website-performance/total-page-weight) | Lower is better | 2000 | 5000 | bytes |
