Site Speed & Core Web Vitals
Page speed is a ranking signal and a conversion lever in one: slow sites bleed both traffic and revenue. This hub breaks down Core Web Vitals — LCP, INP, and CLS — and the concrete engineering work behind them, from image and JavaScript optimization to caching, hosting, and font loading. The five guides below walk through diagnosing bottlenecks with real tools and fixing them without guesswork.

Understanding Core Web Vitals: What LCP, INP, and CLS Actually Measure
Confused by Core Web Vitals? This guide explains LCP, INP, and CLS in plain terms, their pass thresholds, and how Google actually scores them.
Image Optimization Techniques to Improve LCP and Overall Page Weight
Cut load times with proven image optimization tactics — next-gen formats, responsive sizing, lazy loading, and CDNs — to improve LCP scores fast.
Reducing JavaScript Execution Time to Improve INP and Responsiveness
Long tasks and bloated JS bundles kill INP scores. Learn how to code-split, defer, and audit third-party scripts to make your site feel instant.
Server Response Time, Caching, and Hosting Choices That Move Core Web Vitals
Slow hosting undermines every other speed fix. Learn how TTFB, caching layers, and CDN choices affect Core Web Vitals and how to fix them.
Font Loading Strategies That Prevent FOIT, FOUT, and Layout Shift
Web fonts often cause hidden CLS penalties. Learn font-display, preloading, and subsetting techniques that keep type fast and layout-stable.
