Prioritised recommendations (click to expand)

P1Cut the mobile JavaScript bundle›

Mobile TBT is 1476ms from 1.2 MB of JavaScript. Defer and code-split non-critical JS, remove unused libraries, audit third-party scripts.

P2Improve mobile LCP›

Mobile LCP is 5.1s. Preload the hero image, reduce server response time and remove render-blocking CSS/JS.

P2Compress oversized images›

Desktop loads 30 MB, almost all images. Serve WebP/AVIF, size responsive images and lazy-load. Aim under 2 MB.
