Shopify Speed Score: How to Get 90+ on Google PageSpeed

Speed can make or break your Shopify store.

Even a one-second delay can drop conversions by 7% or more. Shoppers today expect instant loading — and if your store lags, they move to competitors. Beyond user experience, Shopify speed optimization directly impacts SEO and sales.

A fast site means smoother checkouts, higher rankings, and happier customers. So, if you’re asking how to get 90+ on Google PageSpeed for Shopify, this is your ultimate guide to optimizing your Shopify store speed.

We’ll cover Shopify PageSpeed Insights optimization, Shopify Core Web Vitals improvement, and the fastest ways to improve Shopify site speed — whether you handle it in-house or with professional Shopify Speed Optimization Services.

Google PageSpeed Insights measures how fast your website loads on both desktop and mobile.
It scores your site from 0 to 100, with higher numbers indicating better performance.

For most Shopify stores, crossing 90+ is challenging because of large images, third-party apps, and theme bloat. But it’s achievable with the right optimization steps.

Understanding your Shopify speed score helps you prioritize fixes. It’s not just about aesthetics — it’s about Shopify performance optimization that directly affects conversions and user engagement.

Several underlying issues can drag down your Shopify site speed.
Here are the most common ones we see when performing our guide to optimizing Shopify speed.

1. Theme Design

A visually rich but heavy theme can slow everything down.
Themes with extra animations, complex scripts, or bulky frameworks reduce performance. Switch to a Shopify theme optimized for speed — lightweight, minimal, and responsive.

2. Oversized Images

Uncompressed or unoptimized images are a silent killer for load times.
Use modern formats like WebP and automated compression tools to keep visuals crisp but fast. This small change can dramatically improve Shopify PageSpeed Insights optimization results.

3. App Overload

Every installed app adds extra code and requests.
Audit your apps regularly and remove any unused ones. Reducing app clutter is one of the best ways to instantly improve your Shopify speed score.

4. Code Inefficiencies

Unused CSS, JavaScript, or Liquid snippets accumulate over time.
Minify and clean them up — even small changes here can raise your Shopify Core Web Vitals metrics.

5. Mobile Responsiveness

More than 70% of eCommerce traffic is mobile.
If your site isn’t mobile-optimized, your Shopify speed score will suffer. This is where Shopify mobile speed optimization services make all the difference.

Now let’s break down the best ways to improve Shopify speed score and get that 90+ PageSpeed target.

1. Choose a Lightweight Theme

Select themes like Dawn or Turbo, which are engineered for performance.
Avoid feature-heavy themes with excessive app dependencies.

2. Optimize and Compress Media

Before uploading, compress images and videos.
Enable lazy loading to display them only when needed.
This is often the fastest way to improve Shopify site speed and boost Google’s performance metrics.

3. Minify Code & Scripts

Remove unnecessary spaces, comments, and characters in CSS/JS/Liquid files.
It may sound small, but it helps browsers render your site faster.

4. Reduce Third-Party App Requests

Apps that call external scripts (like tracking tools or chat widgets) can slow your site.
Keep only what’s essential to operations.

5. Enable Browser Caching

Caching allows returning visitors to load your pages instantly.
Shopify has a CDN by default — make sure all theme assets are served through it.

6. Simplify Fonts & Icons

Custom fonts and icon libraries can add megabytes of extra data. Stick to system fonts or optimized Google Fonts.
