7 Ways to Make Your Website Load Under 1s

Speed 6 SLIDES Actionable engineering techniques we use to achieve 100/100 Lighthouse performance scores and sub-second First Contentful Paint times. Engineered by Vishal Mehta • Hwt Techy 3 min story • Frontend Developers, SEO Managers, Business Owners Start Story

Replace Legacy JPEGs and PNGs with AVIF

TECHNIQUE 01: AVIF & RESPONSIVE SRCSET 1 / 4 AVIF delivers 50% better compression than WebP and 80% better than JPEG with identical perceptual fidelity. Always serve 400w variants to mobile users. 68% Average bandwidth reduction using AVIF format Implement automated Sharp build-time optimization scripts Preload Largest Contentful Paint (LCP) images in HTML head Set explicit width/height to eliminate Cumulative Layout Shift VETERAN ARCHITECT TIP Never load a 1920px image on a 390px mobile viewport: use responsive imagesrcset. Image Optimization Service

Eliminate Render-Blocking External Stylesheets

TECHNIQUE 02: INLINE CRITICAL CSS 2 / 4 External CSS files block the browser from painting initial content until the network request completes. Inlining critical CSS renders the viewport instantaneously. <1.2s Mobile First Contentful Paint (FCP) achieved Extract above-the-fold critical styles directly into HTML Set CSS extraction threshold to Infinity in SvelteKit/Vite Eliminate unused CSS classes through Tree-shaking VETERAN ARCHITECT TIP An inlined stylesheet of 25KB costs zero additional round-trip times (RTT). Audit Your Critical CSS

Stop Analytics & Tags From Blocking Main Thread

TECHNIQUE 03: DELAY 3RD PARTY SCRIPTS 3 / 4 Google Analytics, Meta Pixels, and chat widgets destroy your Total Blocking Time (TBT). Delay them until 3 seconds after page load or on first user touch. 0ms Total Blocking Time (TBT) on mobile devices Inject heavy tracking scripts dynamically via setTimeout Execute GTM containers only after the critical render path Maintain 100% analytics accuracy while scoring 100/100 VETERAN ARCHITECT TIP Never put synchronous 3rd-party tags in head without async/defer or delayed execution. Optimize 3rd Party Scripts

Serve Content via Brotli From Nearest Edge Node

TECHNIQUE 04: EDGE CACHING & COMPRESSION 4 / 4 Brotli compression outperforms Gzip by 20%. Combine with global edge caching (Cloudflare/Fastly) so TTFB drops below 50ms worldwide. <50ms Time to First Byte (TTFB) on edge networks Enable Brotli compression level 6 on your reverse proxy Set Cache-Control: public, max-age=31536000, immutable for assets Use stale-while-revalidate for dynamic API endpoints VETERAN ARCHITECT TIP Combine HTTP/3 QUIC protocol with Edge CDN caching for zero-latency mobile browsing. Get Sub-Second Speed
