7 Best Away Do Advanced Shopify Website Speed Optimization

 Learn How to Improve Shopify Store Speed for Better Performance


How to do advanced speed optimization for a Shopify website

🔹 1. Optimize Shopify Theme Code

  • Minify CSS & JavaScript: Remove extra spaces, line breaks, and unused code. Tools like UglifyJS or online compressors can help.

  • Remove Unused CSS/JS: Many Shopify themes load unnecessary scripts. Identify and delete unused ones to reduce page weight.

  • Defer Non-Critical JavaScript: Ensure important content loads first while background scripts load later.

🔹 2. Reduce Third-Party App Bloat

  • Every installed app injects additional CSS/JS into your store.

  • Audit apps and remove any that are not essential.

  • Replace multiple apps with an all-in-one solution when possible.

  • Use lightweight scripts or custom code instead of heavy apps.

🔹 3. Optimize Images & Media

  • Use next-gen formats (WebP, AVIF) for better compression.

  • Implement lazy loading so images load only when visible on the screen.

  • Compress product images without losing quality (TinyPNG, Crush.pics, ImageOptim).

  • For videos, use YouTube/Vimeo embeds instead of hosting them directly.

🔹 4. Enable Shopify’s Native Features

  • Shopify CDN (Content Delivery Network): Shopify already serves static files via CDN, but ensure all images and assets are properly linked.

  • Shopify Online Store 2.0 Themes: If you’re on an older theme, upgrade to OS 2.0 for better performance structure.

🔹 5. Use Liquid Code Optimization

  • Replace for loops with paginate where possible to reduce queries.

  • Use include instead of render for snippets in performance-critical areas.

  • Cache snippets and data using Shopify’s section schema to avoid repeated server calls.

🔹 6. Optimize Fonts

  • Use system fonts (Arial, Helvetica, etc.) or preload custom fonts.

  • Limit the number of font weights and styles.

  • Serve fonts locally instead of fetching them from third-party servers.

🔹 7. Leverage Browser Caching

  • Ensure static files like CSS, JS, and images are cached so returning visitors load pages instantly.

  • Shopify manages caching automatically, but you can optimize app scripts and custom scripts by setting long cache lifetimes.

🔹 8. Implement Advanced Techniques

  • AMP (Accelerated Mobile Pages): Use AMP versions of blog posts for faster loading on mobile.

  • Server-Side Rendering (SSR) for React Apps: If your store uses React components, SSR improves initial load times.

  • Preloading Critical Resources: Preload hero images, above-the-fold content, and key fonts.

🔹 9. Test, Monitor & Improve

Use these tools to monitor performance:
