Performance-Driven Development (Core Web Vitals)
Performance-Driven Development for Core Web Vitals
Code-level optimizations to hit LCP, INP, and CLS targets. We refactor themes, tune render paths, and harden servers so WordPress stays fast—even under real traffic.
What we improve (semantic variants in subheads)
Largest Contentful Paint (LCP)
Critical-path CSS/JS, server TTFB, image formats (AVIF/WebP), and responsive loading.
Interaction to Next Paint (INP)
Defer long tasks, hydrate islands, throttle listeners, and prioritize user input.
Cumulative Layout Shift (CLS)
Reserve media space, stabilize fonts, pre-size components, and avoid late ads.
Server & Build Pipeline
OPcache, HTTP/2/3, CDN strategy, image/CDN cache keys, and build-time minification.
How we hit the metrics
Render-path refactors
Split bundles, ship only what’s needed per route, and load non-critical code after first interaction.
Media & font strategy
Preload hero assets, font-display swap/fallbacks, AVIF/WebP, and aspect-ratio placeholders.
Data fetching
Cache-first SSR, stale-while-revalidate, compressed JSON, and reduced object hydration.
Third-party control
Defer/async tags, consent-gated marketing scripts, and performance budgets per page.
Platform tuning
PHP 8.x, OPcache/JIT, HTTP/3 + TLS, CDN edge caching, and optimized database queries.
Observability
RUM dashboards for LCP/INP/CLS, error traces, and regression alerts by release.
Want measurable wins in LCP, INP, and CLS—without redesigning the site?
Performance snapshot (before/after sample)
| Metric | Target | Typical Result |
|---|---|---|
| LCP (mobile) | ≤ 2.5s | ~1.6–2.2s |
| INP (mobile) | ≤ 200ms | ~80–160ms |
| CLS | ≤ 0.1 | ~0.01–0.06 |

Core Web Vitals — FAQs
Lab metrics improve immediately after a release; field metrics (CrUX) typically reflect gains within 28 days as user data updates.
Yes—render-path code, assets, and server stack (PHP/OPcache, CDN, HTTP/3) are tuned together for durable results.
Usually no. Most gains come from code, loading strategy, and server/CDN tweaks—though we may reserve space to prevent CLS shifts.
Yes—we collaborate with your provider, or set up a tuned stack using Cloudflare/AWS/Azure and your preferred host.
