Technical Core Web Vitals audit, LCP optimization, heavy script removal, lazy load in NuvemShop themes and audit of apps degrading storefront performance.
LCP above 2.5s on mobile is associated with up to 32% higher abandonment rates. The diagnosis identifies exactly what is slowing your store down.
Core Web Vitals
Every tenth of a second improvement in LCP has a measurable impact on conversion rate — especially on mobile, where most NuvemShop store visits happen.
Time to render the largest visible content. Above 2.5s is rated "Poor" by Google and directly impacts ranking and conversion.
Visual instability caused by elements shifting during load. Pop-up, chat and review apps are the main culprits in NuvemShop.
Response time to user interactions. Poorly implemented third-party scripts (pixels, chat, apps) are responsible for 80% of high INP cases.
Average result measured in full-scope NuvemShop speed optimization projects — audit, fixes and validation with real CrUX data.
What is audited
Technical diagnosis with real data — PageSpeed Insights, CrUX, Lighthouse and manual analysis of theme and installed apps.
Optimization do LCP com foco nas imagens que mais impactam o primeiro carregamento da vitrine e das páginas de produto.
Identification and handling of scripts that block page rendering and contribute to high LCP and degraded INP.
Analysis of the real impact of each app on PageSpeed — which are justified by their benefit and which merely slow down the storefront.
External fonts and third-party CDN resources are often responsible for significant delays in first contentful paint.
Mobile is where most NuvemShop visits and purchases happen — and where performance most impacts conversion.
Cache settings, TTFB and server optimizations that complement theme and script improvements.
Process
Process estruturado do diagnóstico à validação com dados reais — sem intervenções às cegas e sem impacto negativo na loja em produção.
PageSpeed Insights, Lighthouse, CrUX and manual theme analysis. Prioritized report with each issue and its measurable impact on LCP, CLS and INP.
Ranking of interventions by expected impact on PageSpeed and conversion — from highest to lowest return.
All optimizations are implemented and tested in a separate environment before any production deployment.
Before/after PageSpeed comparison, CrUX validation with real user data and 30-day post-deploy monitoring.
Apps and performance
Apps are necessary, but each one injects scripts into the storefront. The audit identifies which ones have a disproportionate impact on LCP and CLS.
Chat scripts load on the main thread and often contribute 0.8s to 1.2s of LCP delay when not loaded lazily.
Review widgets inject heavy CSS and JS on initial load — even when the user has not yet reached the reviews section.
Pop-up scripts load before main content and cause high CLS when they fire without proper timing and positioning configuration.
Meta Pixel, TikTok Pixel and poorly configured analytics scripts block the main render when not loaded asynchronously.
