How to fix page speed warning on Shopify Plus
Reduce your page load time to under 1.5 seconds by optimizing images, eliminating render-blocking resources, and enabling caching and compression.
Steps for Shopify Plus
- All standard Shopify steps apply (see Shopify above).
- Scripts: In Shopify Plus, go to Online Store > Themes > Edit code and audit the checkout.liquid file for any checkout-specific scripts added by an agency or app. Remove unused checkout scripts — they delay the most conversion-critical page in your funnel.
- Launchpad / Flow: Use Shopify Flow to schedule script-heavy promotional apps to activate only during sale periods rather than running 24/7.
- Headless consideration: If your Plus store is on a headless or custom storefront (Hydrogen / Remix), work with your developer to implement streaming SSR, route-based code splitting, and Shopify's built-in CDN for media.
What is page speed warning?
Page load time is how long it takes for a visitor's browser to fully display your store page after they click a link or type your URL. When a page takes more than 1.5–2 seconds to load, visitors experience a noticeable delay before they can see and interact with your content. A load time of 3 seconds or more (like the example finding) is considered slow by both Google and modern shoppers. Page speed is measured by several signals — the most important being Google's Core Web Vitals, which assess how fast your content appears, how quickly it becomes interactive, and how stable the layout is as it loads.
Google has officially made page speed and Core Web Vitals a direct ranking factor for all pages. Slow pages rank lower in search results, meaning fewer people find your store organically — costing you traffic and revenue before a visitor even arrives. For shoppers who do visit, studies consistently show that every additional second of load time reduces conversions: a 3-second page loses a significant portion of mobile shoppers to bounce before they see a single product. Slow stores also perform poorly in Google's mobile-first index, which evaluates your mobile experience first when deciding your rankings. Fixing page speed is one of the highest-ROI improvements an ecommerce store can make — it simultaneously boosts your SEO rankings, increases conversion rates, and improves accessibility for users on slower connections or lower-end devices.
