# Shopify speed optimization

> Make your Shopify store faster on PageSpeed and Core Web Vitals: a 47+ point inspection and no scripts that trick the test.

A slow store loses sales before shoppers even see your products. Our optimization speeds up how fast your Shopify store loads, and it shows in your numbers: lower bounce rate, more visits put to use, better Google rankings and, in the end, more revenue, margin and ROI.

## Results from our last 100 optimized stores

PageSpeed Insights Performance score and Lighthouse metrics, before and after optimization, across the last 100 stores we worked on. The average score improved by more than 50%, and all 100 stores improved.

| Metric | Before | After | Change |
| --- | --- | --- | --- |
| Performance score (average) | 40 | 64 | +60% |
| Performance score (median) | 38 | 65 | +71% |
| Total Blocking Time (median) | 1,080 ms | 320 ms | −70% |
| Speed Index (average) | 8.9 s | 4.4 s | −51% |
| First Contentful Paint (average) | 3.9 s | 2.2 s | −42% |
| Largest Contentful Paint (average) | 14.6 s | 8.6 s | −41% |

_Every store starts from a different place, so we never promise a specific score._

## Is 64 a low score?

No. A PageSpeed score depends on many factors beyond the code: the theme, the installed apps, the size of images and videos, marketing scripts and the way Google itself measures, on a simulated slow phone. That is why a real store, full of features that sell, rarely reaches 100.

Be wary of anyone who promises a 100: it is usually a trick that shows Google's bot a different page while shoppers get the slow store. The average of 64 is the real result across 100 different stores, and some of our stores score well above it.

## What a faster store improves

Speed isn't just a test score. It moves metrics that matter to your business:

- **Connect rate:** Out of every 100 ad clicks, how many become a visit with the store actually loaded. A slow store loses people before it opens, and you still pay for the click.
- **Bounce rate:** Fewer people give up on the first screen when it shows up fast, especially on mobile.
- **Traffic, rankings and SEO:** Speed is part of the signals Google considers, and a faster store makes better use of every visit it gets.
- **Tracking:** When the page loads sooner, your pixel and analytics record more visits, so your campaigns learn from more complete data.
- **Revenue, margin and ROI:** More visits put to use with the same ad spend turn into more orders and a better return on ad spend.

## What we deliver

- **A 47+ point inspection:** We review the whole store, from backend to frontend: theme, apps, images, fonts, scripts and everything that slows loading.
- **All four PageSpeed categories:** Performance, accessibility, best practices and SEO, plus how AI agents and AI search read your store.
- **A store that is really faster:** We improve the store your shoppers get, not just the test score.
- **Work on a draft:** Everything happens on a copy of your theme, never on the live store.

## What PageSpeed and Core Web Vitals are

**PageSpeed Insights** is Google's tool that scores a page's performance from 0 to 100, using Lighthouse. **Core Web Vitals** are the three metrics Google uses to measure what real visitors experience:

- **LCP · Largest Contentful Paint:** How long the largest image or text block on screen takes to appear, usually your hero banner or product photo.
- **INP · Interaction to Next Paint:** How quickly the page responds to a tap or click, like opening the menu or picking a variant.
- **CLS · Cumulative Layout Shift:** How much the layout jumps while loading, like a button that moves just as you tap it.

_Every second of waiting is another chance for a shopper to give up, especially on mobile. Core Web Vitals are also part of the page experience signals Google considers when ranking results._

## Watch out for themes that fake their score

Some resold themes ship scripts that show Google's test a different page from the one shoppers get. The score looks great, but the store stays slow for buyers, and tracking (pixels and analytics) can stop working.

We don't do that. Unlike those who add scripts to fool measurement tools, we fix what needs fixing, remove what isn't needed or give recommendations so your store performs as well as it really can.

We also look for these tricks during the diagnosis. If your store scores high but still feels slow on a phone, it's worth a check.

## How it works

1. **Detailed inspection:** We check 47+ points that affect your store, from backend to frontend, and list what is slowing it down.
2. **Fixes on a draft:** We fix what's needed and remove what isn't on a copy of your theme, without touching the live store. Anything that depends on you, like replacing an app, becomes a recommendation.
3. **You review and publish:** You check the preview and publish when you're happy.

## Frequently asked questions

### How do I make my Shopify store faster?

Start by measuring: check your PageSpeed score and find out what weighs the most for shoppers on mobile. In a Dash optimization, we run that diagnosis and make the fixes on a copy of your theme, in 1 to 2 business days.

### How much does Shopify speed optimization cost?

It is quoted per project, because it depends on your theme and apps: the proposal comes after a review of your store. It takes 1 to 2 business days, and we can quote in your local currency on request.

### Can you guarantee a 90+ PageSpeed score?

No. Scores depend on your theme, apps and content, so a guaranteed number is a red flag. What we commit to is the method: a measured diagnosis, fixes on a copy of your theme and no score-faking tricks.

### Do you work on my live store?

No. Every change is made on a copy of your theme (an unpublished draft). You review the preview and publish it yourself when you're happy.

### Do I need to remove apps to make my store fast?

Not necessarily. The diagnosis shows what weighs the most on your store, so you can decide what is worth keeping.

### What's the difference between the PageSpeed score and Core Web Vitals?

The score is a lab simulation run by Lighthouse. Core Web Vitals (LCP, INP and CLS) are also measured from real Chrome users when your store has enough traffic. We work on both.
