Core Web Vitals Optimization that turns speed into rankings and conversions.
If your site “feels” slow, visitors bounce and Google sees it in your performance signals. We diagnose what’s actually holding you back, then ship a fix plan (or implementation) that improves perceived speed, responsiveness, and visual stability—without breaking tracking, SEO, or design.
Clear deliverables. Monthly reporting (if ongoing). Kickoffs scheduled weekly.
What Core Web Vitals optimisation actually means
Most “speed work” fails because it’s generic. We map issues to the three metrics Google evaluates (plus the supporting signals), then build a plan your dev team can ship safely.
LCP (Loading performance)
Make the main content appear fast—especially on mobile and average devices.
- Hero image & font strategy
- Render-blocking CSS/JS reduction
- Server response + caching improvements
- Critical path & above-the-fold optimisation
INP (Responsiveness)
Reduce input lag and long tasks so the site feels snappy during real interactions.
- JavaScript execution and long-task trimming
- Third-party script governance (ads, chat, pixels)
- Event handlers + main thread decongestion
- Interaction profiling and regression protection
CLS (Visual stability)
Stop unexpected jumps that sabotage reading, scrolling, and conversions.
- Reserve space for media, embeds, and ads
- Font loading strategies (FOIT/FOUT control)
- Animation/transition safety
- Consent + banner stability fixes
Common bottlenecks we fix (and how we fix them)
We translate Lighthouse + DevTools findings into fixes that improve field performance (CrUX / Search Console groups).
Fast wins (often within 1 release)
- Proper image sizing + next-gen formats + preload key hero media
- Remove render-blocking CSS, reduce unused rules, and critical CSS where safe
- Fix missing width/height on media and stabilise above-the-fold layout
- Font loading strategy to prevent layout shift and slow text paint
- Defer non-critical third-party scripts (without breaking conversion tracking)
High-impact engineering fixes (template-level)
- Caching strategy (server + CDN), TTFB reduction, and consistent HTML delivery
- Code splitting and route-based bundles to reduce main-thread pressure
- Remove long tasks (INP): break work, schedule, and avoid blocking interactions
- Replace unstable embeds, banners, and dynamically injected UI
- QA and monitoring plan so improvements hold over time
CWV checklist (what we check before we touch code)
This is the “why” behind our fixes—so your team understands what changed, what to watch, and what to avoid.
Loading: get the main content visible fast
- LCP element identification (what is actually the LCP?)
- Image strategy (sizes, formats, preload, fetchpriority)
- CSS delivery and critical path (blocking, unused, cascade)
- Font strategy (preconnect, preload, swap, metrics overrides)
- Server + caching + CDN (TTFB consistency)
Responsiveness: reduce input lag and long tasks
- Long task profiling (main-thread offenders)
- Third-party controls (tag governance without breaking analytics)
- Event handler hygiene (debounce, passive listeners, minimal work)
- Bundle + route splits (ship less JS to users)
- Regression guardrails (what not to re-introduce)
Stability: stop unexpected layout shifts
- Reserve space for media, embeds, and banners
- Font-induced CLS (fallback sizing, swap strategies)
- Late-loading UI (cookie/consent, promo bars, chat widgets)
- Animations/transitions safe patterns
- Post-release verification against real pages (not just a homepage)
Our CWV optimisation system (built for safe releases)
You get clarity first, then fixes. We prioritise what will actually move field data, and we validate post-release so results stick.
Baseline & prioritise (what matters most first)
We reconcile lab tools (Lighthouse/PageSpeed) with field signals (CrUX/Search Console groups) so you don’t chase “green scores” that don’t move real users.
- CWV grouping: templates/pages with shared issues
- Root-cause mapping: what’s hurting LCP vs INP vs CLS
- Prioritised tickets with impact + effort notes
- “Do not break” list (SEO, tracking, UX)
Fix LCP bottlenecks (get the page to “feel fast”)
We optimise the critical path so users see primary content quickly—especially on mobile.
- Hero/media delivery: sizes, formats, preload strategy
- CSS/JS trimming: remove blockers and unused code safely
- Server + cache plan: improve TTFB consistency
- Above-the-fold layout strategy for stable render
Protect INP (snappy interactions, fewer long tasks)
We keep interactions responsive while maintaining analytics, pixels, and consent behaviour.
- Long-task profiling and remediation plan
- Third-party governance: defer, load conditions, audit bloat
- Event handler hygiene + UI thread safety
- Regression checklist (what causes INP to drift)
Stabilise CLS (stop the page from “jumping”)
Visual stability is conversion stability. We remove shifts caused by media, fonts, and dynamic UI.
- Reserve space: images, videos, iframes, embeds
- Fonts: swap/metrics overrides to reduce reflow
- Consent + banners: non-invasive patterns
- Animation safety: transform-first, layout-safe
QA & monitor (so gains hold after launch)
We validate on real templates, confirm tracking, and set up a workflow to prevent regressions.
- Pre/post release verification checklist
- Field vs lab validation notes (what to expect and when)
- Monitoring plan (Search Console CWV report)
- Optional ongoing pairing with Technical SEO
