How to Improve Your Shopify Store Speed

As more businesses are moving their operations to the web, they choose Shopify, a robust cloud-based platform particularly suitable for small and medium-sized companies. It enables merchants to set up and launch online stores in literally days.

If we take a look at the data on builtwith.com, we’ll see that the popularity of Shopify has been growing by leaps and bounds recently and has especially been on the increase over the last couple of years.

With so many competing Shopify stores around, every aspect of a site is important: content, security, user experience, and others. However, there’s probably no characteristic as crucial for an e-commerce store, a Shopify store in particular, as the loading speed. Here is why.

WHY SPEED MATTERS?

If we compare the conversion rate of online shoppers worldwide over the past few years, we will see a steady decrease in this indicator. While 2.9% of Internet users converted in the second quarter of 2018, in the second quarter of 2019 this number amounted to only 2.58%.

One big reason why consumers don’t convert is slow operation of online stores. No one wants to watch a progress bar or wheel on a blank screen. According to some data from Google’s analysts, a site that takes from 1 to 3 seconds to render may experience a 32% higher bounce rate. Sites that perform even slower than that simply have no chance to survive.

Apart from actually waving good-bye to potential customers, owners of crawl-at-a-snail’s-pace Shopify stores are in for another unpleasant discovery: Internet users may not even find their sites on search engines. How is that?

The thing is that search engines, with Google in particular, regard site speed to be an all-important indicator in their ranking algorithms. If a site is slow and causes bounces, Google thinks, “Well, I’ll move it down the list now. I don’t want users to think that I’m incompetent at my job of directing them to the most relevant, fast, and high-quality resources.”

Thus, a crawling Shopify store is a candidate for relegation to Google’s ‘dark zone’ where few Internet users ever roam.

So, how can you make your Shopify store faster in order to avoid the problems we’ve just described? Well, the Shopify guys have already done some work for you, but there’s some magic you can put in yourself as well. Let’s take a look at both of these ends so that you can see the whole picture.

WHAT SHOPIFY CAN DO FOR YOU

#1: Shopify Lets Visitors Access Your Store Quickly in Any Part of the World

E-commerce is getting more global, reaching out to every corner of the planet. A site that’s not optimized for delivering content fast to users regardless of their geographical location is sure to be less popular among the international audience.

What can you do then? A solution to this problem was found a while ago. This is a Content Delivery Network, or CDN for short. In a nutshell, it’s a number of interconnected servers placed in different parts of the Earth. A CDN allows a user located somewhere in Germany to access your Shopify site as fast as a user sitting in their California home.

Normally, with sites based on content management systems such as WordPress, owners have to connect to a CDN themselves. Shopify, on the other hand, provides off-the-shelf access to a high-quality CDN with no additional fees attached and no set-up effort required. So whatever continent your visitors come from, the loading speed of your Shopify store stays the same.

Shopify makes working with a CDN even more efficient by using URL filters for images and other visual content that can significantly pull down on a site’s speed. When an image has been altered in some way, its version number changes. Then, Shopify passes this information to the CDN, which retrieves the most up-to-date copy of the resource. The main takeaway: the site “flies.” To learn more about the Shopify URL filters, visit this site.

Note that using the default Shopify CDN is not the only option. There are other CDN solutions available. However, with the platform-provided CDN, you can be absolutely confident in the smooth and fast operation of your store independent of a visitor’s location.

#2: Shopify Provides Scalable and Fast Hosting

The platform is hosted on its own server, in contrast to self-hosted systems like Magento. Shopify’s users don’t have to deal with any server configuration or server speed optimization. All this is taken care of by the Shopify team.

Good hosting is especially important during holiday sales when the number of visitors increases exponentially. This exerts a tremendous pressure on the infrastructure, causing some sites to stop functioning properly or completely. As a consequence, e-commerce sites suffer a loss of revenue.

Shopify excels in the server response time, exceeding the speed of some other similar cloud-based platforms up to 4 times, let alone self-hosted solutions.

Even with online shoppers’ activity at its peak, Shopify stores can easily sustain the load since the platform provides unlimited bandwidth. For Shopify Plus, the server is almost never down (99.98% uptime). Read why it’s so important to avoid downtime in e-commerce.

WHAT CAN PREVENT YOUR SHOPIFY STORE FROM RUNNING FAST AND WHAT YOU CAN DO ABOUT IT

It’s not all a bed of roses, though. As your store is growing more mature, you may notice that it’s not working as fast as it used to. “Hey, what’s going on?” you ask yourself. There can be several reasons why even Shopify sites may suddenly stop performing well. Let’s go over the most common of those issues and see how you can combat them.

#1: Too Many (Low-Quality) Add-Ons

Shopify is a great platform capable of doing all the useful things out of the box. As is the case with other e-commerce systems, though, it’s also extremely flexible and allows site owners to add extra functionality by means of apps.

Need to translate your store for international customers? Install an appropriate app. Want a new safe delivery option added to your site for the duration of the quarantine? Take advantage of this app. The variety of applications is huge, and they allow you to address every aspect of managing your store.

All this, however, comes at a cost. Numerous apps running inside your Shopify site may deal a painful blow to its performance. This is because even if you’re not using an app, its code is still executing behind the scenes.

Alas, you have to make a very tough decision here: which apps to “kill.” Go over all your add-ons and get rid of those you rarely or never use. Besides, there’s probably no point in keeping two apps that serve the same purpose, such as those that facilitate working with social media. Leave only the one that’s more effective in your opinion.

Disconnecting apps from your store is only part of the work you have to do, though. Whenever an app is installed, it adds its business logic to your store’s internal files, so you also need to find and erase every trace of the app you’ve just uninstalled.

Another important thing when it comes to apps is that some of them may be of low quality. Their code can be buggy. Besides, it is stored on an app provider’s own server, which may not be configured for speed and optimal performance. There are a lot of factors that can affect a server’s operation, starting from how it is actually set up and how much memory it has and ending with request processing sequence.

The GetDevDone Shopify development team knows what apps in the Shopify app store are the most stable and can use them as tools to create the most complex business logic without losing data processing speed and ensuring the highest speed on the front end.

#2: Your Theme Is Not Fast Enough

A Shopify store theme may look and feel fantastic. It may have a unique design and tons of cutting-edge features. However, it may cause the store to load and run so slowly that users may not even wait to see how beautiful it is and simply bounce away.

Therefore, knowing if the theme you’ve built or downloaded from the store is fast enough is very important as far as performance is concerned. We suggest the following steps to address this problem:

1. Find out the title of your theme by using a website like this one.
2. Find out how fast your theme is and what needs to be changed to speed it up. Use this service.

Once you’ve determined your theme speed. you can look for another ready-made one on the official website or on other resources.

Other options include tweaking the existing theme’s code and building a completely new theme from the ground up. Both of these alternatives assume deep knowledge of the staple web technologies, design, and user experience. Naturally, they are also not free and can cost quite a pretty penny down the line.

However, what you get as a result outweighs all the expenses, believe us. A fast, reliable, well-tested, and secure custom Shopify theme is a surefire way to ensure your customers’ trust and loyalty.

#3: Your Images Are Too Large or Too Many

Visuals for Shopify stores are their curse and blessing at the same time. It’s obvious that no e-commerce site can do without visual presentation of goods. Have you ever seen an online store with textual descriptions only? We haven’t.

A clear, high-quality image can say so much more than just plain text. However, visuals can also be heavy sinkers for e-commerce stores, taking up well over half of their total byte size, so you must always seek a compromise between quality and speed.

First, take stock of the images that you’ve added or are adding to your site. Those with a high dpi (dots per inch) value should be reduced in weight. The provider itself recommends using images of 2048×2048 pixels for square photos of goods.

You can find a bunch of various tools for this purpose such as this one. They will allow you to make your images smaller but keep their quality intact.

If you absolutely must retain the high resolution of certain or all of your visuals, consider using the so-called lazy loading technique. Without getting into the nitty-gritty, it adds high-dpi images to a page only after the former has completely rendered in the browser.

Apart from modifying your images, you should also decide if you need so many of them. Even optimized images, when used in large quantities, may not help you achieve your goal. This is because every image sends a request to the server.

The more resources to be loaded, the more requests sent. Every request waits for a response. This lengthens the loading time. As our practice shows, the best way to address this problem is to use data URIs (Uniform Resource Identifiers).

In general terms, data URIs allow you to convert an image (or any other type of file for that matter) into a string and put it right into the HTML or CSS code. Visit this blog to learn more about data URIs and see an example.

Unlike a real image, a data URI sends zero requests to the server, thus reducing the loading time tremendously. There are some online data URI generators you can use, such as this one, but the recommended practice is to generate data URIs using JavaScript functions (.toDataURL(), and .decodeURIComponent()) right inside your store’s code.

Does this effective technique seem a bit complicated to you? No worries. The GetDevDone Shopify development team can help you with the image to data URI conversion to make your Shopify store times faster.

#4: All Your Tags Get Loaded on Every Page

Whenever you add a marketing app to your Shopify store, it provides snippets of code called tags that you incorporate into the theme.liquid file. These tags are used to send some data to the tool when an event on a certain page is generated, such as clicking a link.

With time, you may have placed so many tags in that file that it affects the loading speed of your Shopify store. The reason is that all those snippets of code execute one by one in sequence when any page is rendered in a browser.

What can you do if all these tools are important for your business growth?. The best solution is to use the Google Tag Manager (GTM).

It enables you to trigger events determined by tags only on some specific pages instead of loading the list of tags for the entire site every time. For instance, if you want to track all the outbound links on a footwear product page, you add the corresponding instructions in the GTM. This reduces the loading time while giving you the marketing data you need.

Getting accustomed to using the GTM requires some learning and practice, though. If you wish to go the self-taught way, you may find this post useful. Otherwise, our Shopify developers can leverage the power of the GTM to the maximum for you.

HOW CAN YOU MEASURE YOUR SHOPIFY STORE SPEED

Of course, you need a point of reference to understand if the speed of your site has improved or not after applying the techniques we’ve listed above. For this purpose, you can take advantage of these tools:

Test My Site	GTmetrix	Pingdom	PageSpeed Insights
Good for testing your site’s speed on mobile devices	Performs the loading speed analysis and measures the time every request took	Analyzes the loading speed and gives tips on how to improve it	Gives a score based on a site’s speed. Points out the most critical issues (for mobiles and desktops) and gives performance enhancement recommendations

CONCLUSION

Loading speed is an important factor that contributes to higher conversion and lower bounce rates. Shopify is a cloud-based solution optimized for fast speed and smooth performance.

Apart from taking advantage of some default features, Shopify store owners can apply certain speed-boosting techniques themselves. They can uninstall unnecessary plugins, use a faster theme or tweak the existing one for better performance, reduce the sizes and numbers of images, and organize their tags by means of the Google Tag Manager.

Of course, there’s so much more that can help Shopify merchants ensure a faster speed of their sites. However, we hope that our advice can serve as a good starting point.

Shopify stgore speed optimization FAQs

What should I check first if my Shopify store has become slower over time?

Start by checking what changed recently: new apps, theme updates, heavier product images, marketing tags, or added sections on key templates. Shopify itself handles hosting and CDN delivery, so a store that becomes slower over time is usually being pulled down by the layers added on top of the platform.

Do not begin with random cleanup. Compare the homepage, collection pages, product pages, and cart separately. A store can feel slow because one product template has oversized media, while the rest of the site is acceptable. Use Shopify’s performance reporting, PageSpeed Insights, and real page testing to identify whether the main issue is loading speed, interactivity, visual stability, or a specific third-party script.

The practical first step is an inventory: apps, theme code, images, and tags. Once you know which layer changed, the fix becomes much less risky.

Do Shopify apps slow down a store even after they are no longer used?

Yes, Shopify apps can still affect performance after they are no longer actively used if they leave scripts, snippets, theme code, or configuration behind. Removing an app from the admin does not always mean every trace of it disappears from the storefront.

This is common in older or heavily changed Shopify stores. An app may have added code to theme.liquid, inserted snippets into product templates, created app blocks, loaded external JavaScript, or left logic that still runs on pages where the feature is no longer visible. The result is extra requests, slower rendering, or code that is hard to understand during future updates.

A proper app cleanup should include a theme code review, not just uninstalling apps. In agency handoff situations, this is especially important because the next developer may inherit performance problems without knowing which app originally caused them.

Is it better to remove Shopify apps or replace them with custom functionality?

Remove a Shopify app when the feature is unused, duplicated, low value, or easy to cover with Shopify’s native settings. Replace it with custom functionality only when the feature is important enough to justify development and long-term maintenance.

Apps are usually the better choice for standard needs such as reviews, subscriptions, loyalty, search, or shipping integrations, especially when the vendor is reliable and the app is actively maintained. Custom work makes more sense when an app loads heavy scripts across the store, conflicts with the theme, creates data problems, or forces the business into a workflow that does not match how the store actually operates.

For agencies delivering client stores, this decision should be made during technical scoping, not after launch. A Shopify development team can review which features should stay app-based, which should be removed, and which are better implemented as cleaner custom logic. The trade-off is simple: fewer apps can improve control and performance, but custom functionality also needs ownership, testing, and documentation.

When is a slow Shopify theme worth optimizing instead of replacing?

A slow Shopify theme is worth optimizing when the design is still useful, the codebase is understandable, and the main performance issues are specific enough to fix. For example, an otherwise solid theme may be slowed down by oversized images, render-blocking scripts, excessive app code, unused sections, or poor loading behavior on product pages.

Replacing the theme is more realistic when the theme has been patched for years, relies on outdated patterns, has too many hardcoded workarounds, or makes routine updates risky. In that case, optimization can turn into expensive repair work without solving the underlying maintainability problem.

A practical test is this: can developers improve the theme without breaking the editing workflow, conversion elements, and tracking setup? If yes, optimization may be enough. If not, rebuilding as a custom Shopify theme can be cleaner than spending more time on a theme that was not built for the current store.

Can a visually impressive Shopify theme hurt conversions if it loads slowly?

Yes, a visually impressive Shopify theme can hurt conversions if users have to wait too long before they can view products, interact with the page, or move toward checkout. The design does not help if the customer leaves before the main content becomes usable.

This is a common trade-off in ecommerce. Large hero videos, animation-heavy sections, sliders, product media galleries, custom fonts, and third-party widgets can make a store look more polished, but they can also delay the first useful view of the page or make taps feel slow on mobile.

The better question is not whether the theme looks good. It is whether the theme helps shoppers make decisions quickly. Product images, trust signals, reviews, pricing, variants, and checkout paths need to load and respond before decorative effects become relevant.

How should Shopify store owners balance image quality and loading speed?

Shopify store owners should keep images sharp enough to sell the product, but avoid serving images that are larger than the page actually needs. Product visuals matter, especially for categories where texture, detail, color, or fit influence the purchase decision. Over-compressing those images can damage trust.

The safer approach is to optimize by context:

• use appropriate image dimensions for the template, not one huge version everywhere
• compress images without visible quality loss
• lazy-load non-critical images below the first screen
• avoid loading full-resolution assets inside thumbnails or decorative sections
• review product, collection, and homepage images separately

The main risk is treating all images the same. A hero image, a product zoom image, a thumbnail, and an icon do not need the same size or loading priority. Good performance work keeps the images that help conversion and removes the weight that shoppers never notice.

Which Shopify speed issues are safe to fix without a developer?

Simple cleanup is usually safe without a developer, but theme-code changes are not. Store owners can often handle basic fixes if they have admin access, a backup, and a clear reason for each change.

Usually safe to handle yourself:

• remove clearly unused or duplicate apps after checking what they affect
• compress and resize images before uploading
• replace oversized homepage banners
• disable unnecessary app blocks in the theme editor
• run PageSpeed Insights and Shopify performance reports before and after changes

Use a developer for removing leftover app code, editing theme.liquid, changing Liquid templates, restructuring scripts, setting up complex tracking rules, or changing performance behavior on product and checkout-related pages. The risk is not only breaking layout. A careless change can remove tracking, damage product page functionality, or create a bug that appears only on mobile or only for certain variants.

How long does a Shopify speed optimization audit usually take?

A focused Shopify speed optimization audit usually takes a few business days if it includes measurement, app review, theme review, tag review, and a prioritized fix list. A quick tool-only scan can be done faster, but it is not the same as a development audit.

The timeline depends on the store’s complexity. A small store with a standard theme and a short app list is faster to assess. A mature store with many apps, custom theme sections, tracking scripts, international markets, or inherited code needs more time because the audit has to separate real performance issues from changes that would create business risk.

For agency workflows, the audit should produce more than scores. It should identify what can be fixed safely, what needs staging, what requires client approval, and what should be postponed because the risk is higher than the likely performance gain. That handoff is often what determines whether the recommendations actually get implemented.

Which speed metrics matter most for Shopify stores in 2026?

The most important speed metrics for Shopify stores in 2026 are the Core Web Vitals: Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift. In plain terms, they show how fast the main content loads, how quickly the page responds to user interaction, and whether the layout stays stable while loading.

For Shopify stores, these metrics should be checked by template type, not only on the homepage. Product pages, collection pages, cart-related pages, and landing pages can perform very differently. A homepage score may look acceptable while product pages are slow because of media, variant logic, app scripts, or review widgets.

Tools such as Shopify’s web performance reports, PageSpeed Insights, and Google Search Console help identify the issue, but they should not replace manual review. For ecommerce, the business question is practical: can shoppers view products, compare options, interact with the page, and move toward checkout without friction?
