Summary
The research benchmarks Shopify storefront performance to help merchants compare their own stores.
Performance measurements reveal opportunities to improve the shopping experience beyond simply choosing a platform.
Use a store-specific audit to identify your biggest bottlenecks and prioritize improvements.
How fast is the average Shopify shop and how does your store’s speed compare?
Building a fast web and mobile experience is essential, especially for e-commerce stores where better performance can directly drive sales and conversions. Just how important is having a fast store?
- In 2016, AliExpress made their site faster by a third and received 10.5% more orders
- In 2008, Amazon found that every 100ms of latency cost them 1% in sales.
- Akamai research shows a 1 second delay in page response can result in a 7% reduction in conversions.
Visitors are more likely to leave without visiting another page (the bounce rate) as pages take longer to load. The bounce rate starts soaring after the site takes 3 seconds to load, reaching a rate of 38% by the time the site takes 5 seconds to load!
Customers have low attention spans and would rather leave than wait for a slow page to load. Unfortunately, high performance is an area that doesn’t get its share of love compared to more sexy features like eye popping themes and email collection spinners.
Let’s say you’re on a 2gb data plan, and you clicked on an Instagram ad for a discount Lebron James jersey. But the page is a whopping 9mb and still hasn’t loaded after 5 seconds. It doesn’t matter that Ashlie from Alabama bought it 7 minutes ago, life is too short to wait for a website to load. You close the tab.
How fast is the average Shopify store?
First, to define page speed we’ll need to define our performance metrics. What does “fast” mean? Page load time alone doesn’t tell the full story.
A website that loads quickly but doesn’t react to user input is worse than a larger page which uses skeleton screens and has better perceived load times. To measure web performance, we will use user centric performance metrics as follows:
| Metric | Description | |
|---|---|---|
| First contentful Paint | Is it happening? When the browser renders the first bit of content. This content differs from the previous page and tells the user that the website isn’t hanging. | |
| First meaningful Paint | Is it useful? When the important parts of the page load. The user can engage with the content and can start consuming it. | |
| Time to Interactive (TTI) | It is usable? When the page’s initial javascript is fully loaded, and the page can reliably respond to user input. |
Performance Results
We ran tests on a simulated 3G network on mobile devices to see more variation in load times. Absolute numbers will vary across devices and networks so to give a base comparison, we tested our sample of shopify stores against 3 of the top grossing e-commerce stores: Amazon, Walmart, and Ebay. These companies spend countless engineering hours on performance and provide a baseline of what page speeds are expected.

| Amazon | 12s (14rd percentile) |
| Walmart | 20s (42th percentile) |
| Ebay | 9.5s (9th percentile) |
All major e-commerce retailers have better scores than shopify across all metrics. A heavily optimized metric is first contentful paint, which is within the top 10% of shopify stores for all three stores. Amazon, Walmart, and Ebay took 2.6s, 2.5s, and 2.4s to display the first bit of content, much faster than the 4.4s for the average shopify store. It’s an especially important metric to optimize as it tells the user that the page is indeed loading. After this first snipper of content, loading indicators or skeleton content will improve perceived load times.

Stores can save a median of 283kb using image formats with superior image compression like WebP. Facebook experienced 25-35% file size savings for JPEGs, and 80% savings for PNGs after switching to WebP. It is supported in Chrome and Opera and provides better lossy and lossless compression for images on the web. Although browser support is not universal, older browsers can use other formats like JPEG 2000 and JPEG XR or fallback to PNG or JPEG.

Render blocking resources are CSS and javascript assets that block the loading of the web page. The browser executes stylesheets, synchronous scripts and imports in the head tag before rendering any HTML content. The average Shopify store can shave 1230ms off rendering times by removing or defering render blocking resources.
Every byte matters!
The average store can save 1.2mb of space, and the 25% worst performers can save at least 2.8mb per page. With an average data plan of 2gb, that’s a lot of saved bandwidth! The most impactful improvement is to remove render blocking resources, because they directly impact first contentful paint, a metric heavily optimized by top e-commerce websites.
How can I improve my shop?
First, run an audit for your own shop using Google’s web audit tool Lighthouse at https://web.dev/measure. This will measure most important performance issues for your website so you see how your theme file and images stack up and fix potential low hanging fruit. Make sure your theme and third party apps use proper minification, and use responsive image loading. It’s also important to measure, monitor and refine performance continually.

FAQ
What does this study investigate?
It examines how Shopify stores perform and where improvements may be available. The findings describe the sampled stores and testing conditions used in the article.
Can the average result tell me exactly how my store performs?
No. An average provides context, but your theme, apps, and content can produce different results. The article recommends auditing your own shop.
What are render-blocking resources?
They are resources that delay the browser from rendering content. The article focuses on CSS and synchronous JavaScript as contributors to this delay.
Why does page weight matter for mobile shoppers?
Large pages require more data to download. The article explains how this can burden visitors using constrained connections or data plans.
What improvements does the article suggest starting with?
Audit the store, review render-blocking resources, and check minification and responsive images. Measure again after changes and continue refining performance.
