Every scan measures LCP, INP, and CLS on a representative set of routes so you can see where real users feel friction. Each metric is graded against Google's pass thresholds, with a clear note on which page element triggered the regression and why.
Long-tasks block the main thread for over 8 seconds after first paint; real users will tab away.
Largest contentful paint is well above the 2.5s good threshold; the hero image is the LCP element.
Interaction to next paint exceeds 200ms; main-thread work blocks input.
Cumulative layout shift is comfortably under 0.1.
Beyond Web Vitals, FlawPilot inspects the bytes you ship. We flag oversized images, render-blocking scripts, missing compression, weak caching headers, and third-party tags that drag the page down so you can prioritize the cuts that move the needle.
Images account for 2.1 MB; consider WebP or AVIF and responsive srcsets.
Two synchronous scripts in <head> delay first paint by ~600ms.
Long-lived assets should set immutable caching headers.
Text assets are compressed with Brotli, level 5.
Every finding is paired with the points it would return to your score and a clear next step. You see at a glance whether resizing your hero image will move your grade more than swapping an analytics tag, and the guidance adapts whether you run Next.js, WordPress, or a static build.
Move the hero image off the critical path or use preload with priority hints.
Split route-level JS so the first paint does not block on dashboard code.
Push the two woff2 files used above the fold to remove a round trip.
Roughly 38% of the shipped stylesheet is unused on article pages.
