A fast Shopify store isn’t just a nice-to-have — it’s a requirement for both Google rankings and customer retention. Google’s Core Web Vitals are a confirmed ranking signal, and research consistently shows that every second of load time costs you conversion rate. If your store is slow, you’re fighting on two fronts at once.
The good news: most Shopify speed problems are fixable. Here’s the systematic approach we use at OneOnic when optimising client stores.
Step 1: Measure First, Fix Second
Don’t guess at speed problems. Use these tools to identify exactly what’s slowing you down:
- Google PageSpeed Insights (pagespeed.web.dev): Run both your homepage and a product page. Focus on the mobile score. Review the “Opportunities” and “Diagnostics” sections for specific issues.
- Shopify’s built-in speed report: In your Shopify admin under Online Store → Themes, there’s a speed report that benchmarks you against similar stores. Check this monthly.
- GTmetrix (gtmetrix.com): Gives a waterfall view of exactly which resources are loading in what order. Useful for identifying specific scripts that are blocking rendering.
The Speed Optimisation Checklist
- Compress all images before uploading: Use TinyPNG or Squoosh to compress images to under 200KB before uploading to Shopify. Shopify serves WebP automatically where supported, but starting with lean images matters.
- Remove unused apps: Every installed app can add scripts to your storefront even when not actively in use. Uninstall any app you haven’t used in 30 days. This is often the fastest single fix for speed.
- Disable unused theme features: If your theme has built-in features you’re not using — parallax scrolling, video hero, animated sections — turn them off in the theme editor. These features load JavaScript regardless of whether you use them.
- Use Shopify’s native image compression: Don’t use external image CDNs or third-party image optimisation apps — Shopify’s built-in CDN already serves optimised images. Adding another layer adds requests without benefit.
- Limit custom fonts to two maximum: Each custom font family requires an additional HTTP request. Use Shopify’s built-in font options or limit external fonts to a maximum of two. Avoid loading multiple font weights you don’t use.
- Check for theme update: Theme developers frequently release speed improvements in updates. If your theme version is more than 6 months old, check for updates in the Theme Store.
- Avoid third-party page builders: Apps like PageFly or GemPages add significant JavaScript overhead. Use your theme’s native sections editor instead — it’s faster and better supported.
What Speed Score Should You Target?
For Google PageSpeed Insights on mobile: aim for 70+. For Shopify’s internal score: above 50 is average, above 70 is strong. For Core Web Vitals: LCP under 2.5 seconds, CLS under 0.1, INP under 200ms. These are realistic targets for a well-optimised Shopify store with standard product photography.
The Fix: Try Granivio Free on Shopify
If you’ve applied all the above fixes and still have poor scores, the theme itself is the bottleneck. Granivio is built with performance as a design principle — lean CSS, deferred script loading, native lazy loading, and clean markup that doesn’t load unnecessary features by default. Stores migrating to Granivio typically see meaningful Core Web Vitals improvements without any other changes.

Frequently Asked Questions
Will removing apps really speed up my Shopify store?
Yes, often dramatically. Many Shopify apps inject JavaScript that runs on every page load, even on pages where the app’s functionality isn’t used. Removing 3–5 unused apps can add 1–2 seconds back to your page speed. You can verify this by using GTmetrix before and after removal to see which scripts disappear from the waterfall.
Does Shopify hosting affect my store speed?
Shopify uses a globally distributed CDN (Content Delivery Network) powered by Fastly. Server response time is generally not the bottleneck for Shopify stores — the issues are almost always client-side (heavy images, too many scripts, render-blocking resources). Shopify’s infrastructure is genuinely fast; the theme and apps are where problems originate.
How often should I check my Shopify store speed?
Run a speed check whenever you: install a new app, update your theme, add a new homepage section, or notice a drop in conversion rate. Otherwise, a monthly check is sufficient. Speed can degrade gradually as you add content and apps, so regular monitoring catches problems before they significantly impact your rankings or conversions.
