Prioritised recommendations (click to expand)
P1Cut the mobile JavaScript bundle›
Mobile TBT is 873ms from 1.8 MB of JavaScript. Defer and code-split non-critical JS, remove unused libraries, audit third-party scripts.
P1Fix broken LCP›
LCP is 13.8s on mobile. Investigate render-blocking resources, slow hero images and failed requests.
P1Fix major layout shift›
CLS is 0.60 on desktop. Set explicit width/height on images and embeds; reserve space for late-loading elements.
P2Optimise images›
Compress and correctly size images, serve WebP/AVIF and lazy-load below-the-fold media.
