How fast is your Shopify store?
Shopify's CDN handles the basics, but apps, themes, and third-party scripts can slow you down. Find out how your store performs and what to fix.
What we check
Our scanner evaluates your store across 8 performance categories and ~30 individual checks using real HTTP requests and HTML analysis.
Page Load Speed
Time to First Byte, total load time, and Shopify product page responsiveness.
Resource Optimization
Shopify CDN auto-WebP, CSS/JS minification, font loading, and OS 2.0 theme detection.
Caching Headers
Shopify CDN cache headers, ETag validation, and long-lived static asset caching.
Compression
Shopify’s Brotli/Gzip compression, static asset compression, and HTML transfer size.
HTTP Protocol
Shopify’s automatic HTTPS, HSTS enforcement, and security header configuration.
Third-Party Impact
Shopify app script count, render-blocking detection, and app impact analysis.
Critical Rendering Path
Render-blocking CSS from apps, critical CSS inlining, and preload hints.
Asset Delivery
Shopify CDN delivery, DNS prefetch/preconnect hints, and resource prioritisation.
Why Performance Matters
A one-second delay in page load time reduces conversions by 7% and increases bounce rates by 11%. Google uses page speed as a ranking factor, meaning slow stores are penalised in search results and lose organic traffic to faster competitors.
For Shopify stores, performance directly impacts revenue. Studies show that stores loading in under 2 seconds have conversion rates 2-3x higher than those loading in 5+ seconds. Mobile shoppers are especially impatient — 53% abandon sites that take longer than 3 seconds to load.
Our performance audit analyses your store's speed from a server and network perspective — checking caching, compression, third-party script impact, and delivery optimisation. Unlike browser-based tools, we focus on the infrastructure decisions that determine your baseline speed.
