From lightweight themes and optimized images to custom apps and lazy loading, there are countless ways your Shopify store’s performance can be enhanced. Learn how to improve Shopify store speed with essential tools, advanced strategies, and real-life success stories where DigitalSuits helped brands cut load times, increase conversions, and build high-performing, scalable stores.
Why improve Shopify site speed?
- User experience. Note that 47% of users won't wait for the website to load for more than two seconds. And the percentage of mobile users leaving websites with poor performance is even higher. Given these statistics, you cannot ignore your Shopify site speed optimization. Otherwise, you may lose half of your customers.
- Google ranking. It's not a secret that site speed is one of the factors Google considers for website ranking. However, this factor is not the most important for ranking, as user bounces and time spent on a page weigh a lot more. Still, optimizing your site speed to at least an average level is essential to ensure pages load quickly enough for both users and search engines.
- Customer loyalty. Fast page load increases customer loyalty and contributes to a better return visitor rate since good website performance is one of the indicators of a company's trustworthiness.
- Conversions. Together with increased customer loyalty, a fast site load increases chances for purchasing from you as this factor influences user decisions at every buyer journey step. Studies show that a one-second load delay can reduce conversions by 7%.
What is the benchmark for Shopify page speed?
Based on the information from the studies above, we can conclude that a page speed benchmark for websites, including Shopify stores, is two to three seconds.
In order to align your store’s speed with speed benchmarks, you first need to check your current speed and then start optimizing your store according to all the steps described below.
How to check your Shopify speed score
After we have learned the reasons to invest in your Shopify store speed optimization, it is time to see how you can measure your site's performance.
To check your current speed score, visit the Shopify web performance dashboard in your admin panel (Analytics > Reports > Web Performance).
In this section, you will find insights not only about loading speed but also about your store's visual stability and interactivity. These metrics are based on Google's Core Web Vitals, which allow for complex and holistic measurement of website performance.
Here is a brief description of the metrics provided in the Shopify web performance dashboard.
- Loading speed (Largest Contentful Paint or LCP by Google) is the time from when a user first requests a page until the largest element on the visible screen is rendered.
- Interactivity (Interaction to Next Paint or INP) measures the time needed to repaint the next frame after user interaction, such as when a user clicks a button.
- Visual Stability (Cumulative Layout Shift or CLS) measures unexpected layout shifts on a page, such as when you lose your place of reading a post because an ad finishes loading.
What is a good Shopify store speed?
In the Shopify web performance dashboard, loading speed is categorized as:
- Good: ≤ 2500 m
- Moderate: 2500-4000 m
- Poor: > 4000 ms
See all the benchmarks for each metric here.
How to check the speed score over time
Click on any card to see detailed statistics over time. This gives you more information about which changes influence your performance, such as how Shopify theme customization services or app installation on a specific day impacts loading speed.
There are also statistics on the number of daily visits that are colored to show the share of good, moderate, and poor performance. You can apply filters, such as Device Type, Date Range, and Time Frame Grouping here.
In addition to your current and historical rates, you can also see recommendations for Shopify performance improvements on the most visited pages, which are typically product, collection, and home pages.
Some other tools for running a Shopify speed test
- Another tool for checking page speed, which you can use in parallel with Shopify's built-in tool, is PageSpeed Insights. This tool gives customizable insights about your page speed on different devices and, like Shopify, provides recommendations for optimizing your website performance.
- You can also leverage the LightHouse Chrome extension to get reports about a particular page in your browser.
- WebPageTest offers additional performance metrics. Here, you can view short videos of how your pages load within milliseconds. Simply enter your website URL to view the results once the test is complete.
Here’s how WebPageTest provides the webpage performance test result:
Which factors influence your Shopify store's speed
Your Shopify store’s performance depends on multiple factors, both technical and design-related. Concentrating on these areas can help you apply effective strategies for Shopify performance optimization to enhance speed, boost conversions, and improve rankings.
- Theme efficiency. Lightweight themes load quickly, while those with additional features are heavier, which can slow performance.
- Code quality. Bloated, unoptimized, or duplicated code can delay rendering.
- Images and videos. Big media files are the most sizeable performance consumer.
- App usage. Every app includes some code that is likely to slow down your store.
- Third-party services and libraries. External services, widgets, or libraries can add delays.
- Hosting and CDN. The CDN of Shopify enables fast content delivery, whereas external hosting or integrations may cause bottlenecks.
- Redirects and broken links. Excessive redirects or errors are added to the HTTP requests.
- Heavy elements. Embedded videos, demanding sliders, and pop-ups can significantly affect performance.
- Traffic spikes. High traffic can slow your store because the server has to handle many requests at once.
There are also factors on the user's side that may affect website loading, such as device and internet connection, as well as local browser cache. For now, let’s focus on tips to address common issues and improve performance.
TOP-11 recommendations for Shopify website speed optimization
Here’s how to improve Shopify site speed using the recommendations below:
1. Limit installed Shopify apps
The narrower your list of installed apps, the fewer chances there are of overloading your store. So consider leaving only the most essential Shopify apps and replacing the rest with lightweight custom solutions.
Our team provides Shopify app development services to help you build custom, high-performing apps tailored to your business needs.
2. Get rid of unnecessary features
Consider optimizing your project with a minimal set of essential features and eliminating non-essential features instead. To accomplish this task, consider rearranging your store's infrastructure and aligning it with the most crucial business objectives. Also, make sure that no features duplicate each other in your store.
For more details on how to streamline your store’s functionality while maintaining a high-performance user experience, check out our guide on major ecommerce website requirements.
3. Audit third-party services and scripts
As with native Shopify apps, minimize third-party apps and scripts by removing those you don't really need or ones you may have forgotten to uninstall.
4. Optimize your images and videos
Basic image optimization includes three steps. First, compress and resize images to the size shown on your website. Next, choose the right format for the smallest image size, like WebP. If you wish to use videos for your storefront, set a maximum resolution limit, minimize your video's bitrate, compress them to minimize their size, and choose the right codec. You can also leverage lazy loading (described below) and autoplay.
5. Check your theme for performance issues
Choose themes from the Shopify Theme Store, as they are thoroughly tested for delivering high performance. However, if you want to develop a custom theme, make sure it meets speed benchmarks. Run Theme Check to identify potential performance issues early. For a faster path to a high-performing custom theme, consider working with experienced Shopify developers who fully understand Shopify optimization techniques. Besides, you can also explore our guide on customizing a Shopify theme for additional tips and best practices.
6. Replace GIFs with efficient animations
Heavy GIFs can be replaced with a lightweight animation using CSS. It compresses files and enhances page loading speed without compromising your site’s visual appeal.
7. Simplify homepage content
Remove unnecessary details on your home page, and concentrate on the core products. A clean design enhances the user experience and improves page loading speed.
8. Enable quick view features
Display fast views of products rather than opening complete pages for each one. It saves server requests and increases browsing speed for users.
9. Make performance regularly
Monitor the speed of your store using tools continuously. Identify bottlenecks after implementing theme updates, application installations, or marketing campaigns.
10. Reduce redirects and fix broken links
Check your site to eliminate broken links and reduce redirects. Leverage tools like Google Search Console to identify 404 errors and resolve or remove them as soon as possible.
11. Streamline navigation
Find a way to optimize internal linking, use clean URLs, and eliminate chain redirects to reduce load times and enhance user experience.
How to speed up a Shopify website using advanced techniques
To dive into Shopify speed optimization even further and extend your knowledge on the subject, we've compiled an additional list of advanced methods our developers use to speed up stores that opted into Shopify retainer services for ongoing support. To understand how continuous monitoring and improvements can keep your store performing at its best, explore core reasons why monthly Shopify support matters.
- Lazy loading
This programming technique not only improves speed and performance but also increases perceived performance, which means users think the website is loading faster than it really is. How does it work? Say you have a collection page with over 100 product images. Obviously, it will take huge amounts of time to load them all at their full size. The trick is to load their low-quality images when a user scrolls through the page. Yet, when users stop at some point, the lazy loading technique provides them with high-quality image analogs.
- System fonts
Using system fonts instead of custom ones improves theme performance since browsers do not need to download your fonts to render texts; instead, they are rendered based on the user's operating system's pre-installed fonts.
- Content Delivery Network (CDN)
Shopify provides a CDN backed by Cloudflare for quick loading of your store around the globe. Files delivered through CDN are compressed, which additionally reduces their size so they can be downloaded faster by browser. To use CDN, add your assets to the theme's folder, either manually through the GitHub Integration or by using the Asset REST Admin API resource.
- JavaScript and Liquid optimization
JavaScript is supposed to be used only as a progressive enhancement of your theme for solutions that can't be implemented by using HTML and CSS. If using JavaScript, avoid introducing third-party frameworks, libraries, and dependencies. Your minified JavaScript bundle size should be no more than 16 KB. Also, minimize the operation time for your Liquid code by optimizing its parts as much as possible.
- Redirects and HTTP requests
Too many redirects can negatively impact your store’s speed as they increase the number of HTTP requests. To manage your URL redirects in Shopify, you can use redirect filters. You will find this option in the Navigation section in your dashboard settings.
- Browser caching
Enable browser caching for your returning visitors to speed up loading your website's content for them. To enable this feature, open the Online Store section in your Shopify admin, then click Preferences, find the Browser caching section, and check the box Enable browser caching.
- Accelerated Mobile Pages (AMP)
Optimizing mobile performance for your store is crucial, as sales through mobile devices make up 60% of all ecommerce sales worldwide. The AMP framework will come in handy here, as it simplifies HTML and limits the use of JavaScript for mobile devices.
- Facets and filters
By leveraging facets and optimizing filtering, you simplify product search for your customers, reducing the number of pages they need to view. Optimized filters significantly enhance user experience and customer loyalty.
- Themes and apps update
Keep an eye on updating your theme and apps in time, as Shopify never stops releasing new features and upgrades that may impact your store's performance. This is especially important if you’ve applied Shopify theme customization services for design and UX refinements, or rely on Shopify theme development to integrate custom features. Staying updated ensures seamless compatibility and avoids performance issues.
- Professional help
Skilled Shopify developers can help optimize store speed and performance, as they're always up to date with Shopify's best practices and solutions.
