Defer third-party scripts until interaction. Drop unused plugin bundles — on most shops these outweigh your own code. - Evidence: PSI-lab · 674 KB JavaScript · confidence: high - **[WARN]** Lazy Loading — 63 images without lazy loading - Fix: Add loading='lazy' to all images below the fold. Keep the hero/LCP image eager-loaded. Native lazy loading is supported by all modern browsers. - Evidence: HTML-heuristic - **[WARN]** CSS File Count — 7 CSS files loaded — HTTP/2+/3 multiplexing reduces the per-file connection cost - Fix: Consolidate CSS files by bundling them into 1-3 files. Each CSS file is a separate HTTP request that blocks rendering until downloaded. - Evidence: HTML-heuristic - **[WARN]** Critical CSS Strategy — 7 CSS files without critical CSS extraction - Fix: Extract critical above-the-fold CSS and inline it in . Load remaining CSS asynchronously: . - Evidence: PSI-lab - **[WARN]** Inline JavaScript Size — 568 KB of inline JavaScript - Fix: Move large inline scripts to external files. Inline JS over 100 KB inflates HTML, prevents caching, and blocks the parser. External files can be cached, compressed, and deferred. - Evidence: PSI-lab - **[INFO]** Third-party Services — Not measured — PageSpeed did not return the third-party audit for this URL - Evidence: PSI-lab - **[INFO]** Render-blocking Resources — Not measured — PageSpeed did not return the render-blocking audit for this URL - Evidence: PSI-lab - **[INFO]** Cache-Control Strategy — Not measured — no Cache-Control on the HTML document; static-asset caching was not sampled - Evidence: HTTP-header - **[PASS]** Server Response Time (TTFB) — 40ms - Evidence: PSI-lab - **[PASS]** First Contentful Paint (FCP) — 1.32s - Evidence: PSI-lab - **[PASS]** Largest Contentful Paint (LCP) — 2.48s — Core Web Vital ✓ - Evidence: PSI-lab - **[PASS]** Total Blocking Time (TBT) — 19ms - Evidence: PSI-lab - **[PASS]** Cumulative Layout Shift (CLS) — 0.004 — Core Web Vital ✓ - Evidence: PSI-lab - **[PASS]** Speed Index — 1.47s - Evidence: PSI-lab - **[PASS]** Text Compression (gzip/brotli) — All text resources properly compressed - Evidence: HTTP-header - **[PASS]** Resource Hints (Preload/Preconnect) — 9 preload, 0 preconnect hint(s) - Evidence: HTML-heuristic - **[PASS]** HTTP/3 (QUIC) Support — HTTP/3 enabled via Alt-Svc header - Evidence: HTTP-header - **[PASS]** Script Loading Strategy — 100% of scripts use async/defer/module (1 async, 0 defer, 1 module) - Evidence: HTML-heuristic - **[PASS]** Font Preloading — 6 font(s) preloaded — faster text rendering - Evidence: HTML-heuristic ### SEO — 73/100 - **[FAIL]** H1 Heading - Fix: Add exactly one H1 tag containing your primary keyword.

Add descriptive, keyword-rich alt text to every image. - Evidence: HTML-heuristic - **[WARN]** Image Format Optimization — Only 48% next-gen formats — 0 legacy images remain - Fix: Convert remaining JPEG/PNG images to WebP (30-50% smaller) or AVIF (50-70% smaller).
