Performance Shopify

Your slow Shopify store is costing conversions every day.

Technical Core Web Vitals audit, LCP, CLS and TTI optimization, unnecessary script reduction and CDN configuration for Shopify stores that need real speed.

Each extra second in load time reduces conversion rate by up to 7%. On mobile, the impact is even greater — and Google penalizes in rankings orgânico.

Core Web Vitals

As métricas que definem a experiência real do usuário

O Google usa Core Web Vitals para medir e ranquear páginas. Uma loja com indicadores ruins perde no SEO e na conversão simultaneamente.

LCP — Largest Contentful Paint
≤ 2.5s
Bom · Acima de 4s = Ruim

Tempo para o maior elemento visual carregar. Imagens hero, banners e blocos de produto são os principais ofensores em lojas Shopify.

CLS — Cumulative Layout Shift
≤ 0.1
Bom · Acima de 0.25 = Ruim

Instabilidade visual durante o carregamento — elementos que "pulam" quando scripts e imagens carregam de forma assíncrona.

INP — Interaction to Next Paint
≤ 200ms
Bom · Acima de 500ms = Ruim

Tempo de resposta a interações do usuário — cliques, toques, teclado. Apps pesados e JavaScript excessivo são as principais causas.

What is audited

Complete technical diagnostic of Shopify performance

The audit goes beyond the PageSpeed score — it maps the real cause of each problem and delivers a prioritized plan by impact.

A store with 12+ active apps injects on average 380kb of extra JavaScript on the product page. The audit identifies which apps contribute to this — and which can be removed or replaced.
🖼️

Image and media optimization

Format verification (WebP/AVIF), sizing, lazy-load and compression. Unoptimized images account for 40-60% of page weight.

📜

App script audit

Mapping of all scripts injected by apps — size, load timing and impact on LCP and INP. Identification of blocking and duplicate scripts.

Render-blocking resources optimization

Implementation of defer, async and strategic preload. Inline critical CSS to eliminate render blocking.

🌐

CDN and cache configuration

Review of Cloudflare or Shopify CDN configurations. Static asset cache, correct headers and gzip/brotli compression.

🔤

Typography font optimization

font-display: swap, critical font preload, character subset and elimination of unnecessary fonts that slow LCP.

📱

Mobile-specific performance

Separate analysis for mobile — where issues are more critical and conversion impact is greater. Simulated throttling with real 4G.

FAQ

Questions about Shopify speed

Frequent questions about Core Web Vitals, PageSpeed, apps and the optimization process for Shopify stores.

Send another question
It depends on the starting point and theme complexity. Stores with a standard theme and few apps can reach 85-95 on mobile. Stores with heavily customized themes and many apps typically stabilize at 65-80 after optimization. The goal is always to improve the real user experience — not just the score in isolation.
There's no fixed number — what matters is the real impact of each app. Apps that inject scripts on the product page and checkout weigh more. The audit identifies which apps contribute to slowness, which duplicate functionalities and which can be replaced by native Shopify solutions.
Yes, directly. Core Web Vitals have been part of Google's ranking signals since 2021. LCP below 2.5s and CLS below 0.1 are treated as positive indicators. Improving these metrics benefits organic ranking and conversion rate simultaneously.
The full audit takes 1 to 2 business days. Optimizations, depending on complexity, take 3 to 15 days. The process starts with the highest-impact improvements — images, blocking scripts and CDN — which deliver visible results quickly.
No, when done correctly. All optimizations are implemented and validated in staging before publishing to production. Visual regression tests are run to ensure no layout element was affected by the changes.
