Why Shopify Speed Matters In 2026: An Introduction
Since Shopify is an ecommerce platform, the speed matters more than ever. According to Google, the optimal loading time for an e-commerce website is 2 seconds.
As this is a significant factor contributing to amplify the Shopify Site Speed, but to let you know why it matters, let us have a look at a statement made in the Shopify Speed Blog:
“If you’re operating a store with an average order value of $60 and 5,000 visitors each day, for example, a one-second delay in site speed could be costing you $9,000 a day.”
Doesn’t this highlight why you should consider reducing your Shopify site’s load time?
If your answer to this is yes, let’s consider in detail why Shopify speed matters in 2026, with a detailed guide to help you optimise your Shopify store.
Why Site Speed Is Critical for Shopify Stores in 2026
Site loading speed is a crucial factor that affects the experience users have on your website. And this becomes more crucial when you are running an Ecommerce store.
Let us have a look at certain speed-related factors for 2026 that show why Site speed is critical for Shopify stores in 2026:
- The average loading speed of a website that shows up on the first page of Google is 1.65 seconds.
- Core Web Vitals now play a crucial role in rankings, and a website with good vitals will ultimately rank higher and have an optimized site speed.
- According to new research by Google, 53 percent of people abandon a website that takes over three seconds to load.
- Google now ranks and indexes websites based on Mobile First Indexing, making it crucial to optimize your website’s speed for mobile devices, as this is required for both indexing and ranking.
- Forty percent of users will not wait for more than 3 seconds before leaving a retail website. Hence, regardless of how great your products are or how large your brand is, your bounce rates will increase significantly, resulting in lost customers and reduced search visibility and page rankings.
Based on these factors, it is clear why Shopify speed optimization is more critical than ever in 2026.
Let’s now move on to our first practical step of improving and boosting Shopify Site speed by diagnosing the speed to identify areas for improvement and enhance speed for better conversions.
Diagnosing Your Shopify Site Speed
Diagnosing your website’s speed is crucial because you cannot effectively address the issue unless you know where the problem lies.
Hence, we need to audit our page loading speed using tools that make it easier to identify any issues with the page loading speed, including the factors that cause these issues.
Google PageSpeed Insights
This is an excellent tool that helps you evaluate the performance of your store based on Core Web Vitals, including LCP, FID (now replaced with INP), and CLS, to help you improve Shopify Core Web Vitals.
This tool helps you evaluate your performance for both the desktop and mobile websites.
Although it evaluates both desktop and mobile websites for speed, we highly recommend checking the mobile tab, given Google’s mobile-first indexing policy.
Here you will find exactly which elements are slowing down the speed of your Shopify store.
GTmetrix
GTMetrix is really helpful as it provides information critical for Shopify, which is stored bloated with app scripts. It shows you which scripts and files are loading in what order.
Use the Structure tab in GTmetrix to identify issues that are impacting your store’s performance, such as large third-party scripts caused by apps.
GTmetrix helps you determine which apps or features to disable to improve your store’s speed.
Shopify Analyzer
Shopify analyzer by Speed Boostr has been built specially for Shopify stores.
This tool helps scan and diagnose Shopify-specific performance issues, such as theme bloat, app overload, and unused code.
We recommend examining the “Theme File Size” and “App Load Impact” metrics, as a large theme file indicates the need to trim down your theme, and you may need to swap apps if you have high-impact apps.
Lighthouse
Lighthouse is a tool developed by Chrome for Developers. It runs in the browser and keeps providing you with performance audits. This tool is really ideal for store owners.
If you want speed-related insights, then you must focus on the “Performance tab” and “Best practices” tab.
Additionally, consider running your tests in incognito mode, without any other extensions, to obtain clean data.
Actionable Shopify Speed Optimisation Tips
Now that we have provided you with some excellent tools to help diagnose the speed issues of your website, let’s move forward with practical Shopify site speed optimization tips.
Image Optimization For Shopify SEO
Image optimization is crucial to enhance the website’s speed. There are specific practical tips to consider when optimising images for optimal performance.
- Do not use third-party sliders with autoplay, as they load multiple images; instead, use click-to-expand image galleries for product pages.
- Always add alt text in your images. This is not just a good accessibility practice, but you can also use it for image SEO by strategically incorporating your keywords into alt text and image descriptions.
- Convert your images for all the products and banners to the WebP format. This format does not compromise on image quality and makes them smaller than the usual PNG or JPEG format.
- You can use Shopify’s built-in filter (image_url) for serving responsive image sizes. The code for it is given below for your assistance:
{{ product.featured_image | image_url: width: 600 | image_tag }}
Reducing App Bloat For Speed Optimization
Sometimes, unnecessary apps or apps related to unused JavaScript or old script tags can bloat your store, significantly impacting its loading speed. Here are some practical tips for you to avoid that:
- Don’t just turn off the apps; completely remove the ones you don’t use.
- To identify apps slowing down your store: Go to your live store, right-click and choose “View Page Source” or open DevTools (Ctrl+Shift+I), then reload the page. In the Network tab, look for scripts from third-party apps, such as chatbots or pop-ups, that may be slowing down your site; remove them if they are not needed.
- Sometimes, even upon uninstalling, apps leave behind unused JavaScript. You can use Shopify Analyzer to detect and remove this leftover code.
- If you are using multiple apps to tackle multiple functions, stop doing so. Choose a single app that performs various tasks, rather than using four separate apps for reviews, upsells, and pop-ups. You can use the Vital app for all these functions.
- Mostly, old script tags that are directly added to your theme code by old apps can slow down your Shopify Store when they get loaded inefficiently. You can use Shopify’s App Embed feature, available in online store 2.0. It helps apps load scripts only when needed and efficiently, without bloating the theme code of your store.
Lightweight Shopify Themes
Heavy themes can significantly impact the speed of a Shopify store. Therefore, you need to take some action to prevent this from happening.
- Choose themes like Dawn, Refresh, or Craft from the Online Store 2.0, which are optimised for website speed.
- If there are any unused sections of the themes, like blog sections or carousels, remove the JavaScript related to them manually.
- There is a Chrome extension named Shopify Theme Inspector, which you can use to audit your theme. It will highlight the slow liquid loops and help you identify bottlenecks in the theme logic.
- If you are a Shopify Plus user or a developer, you can add important CSS to the HTML of your theme file to make your page load faster. This can be done in the (theme.liquid) file before the closing </head> tag.
Lazy Loading For Shopify Mobile Speed Optimization
With the help of Lazy Loading, you improve the speed of your Shopify store. This happens because it only loads the images or videos when they’re needed, which is excellent for mobile user experience.
With lazy loading, the initial load time is reduced, and users enjoy a better experience, which in turn boosts your Core Web Vitals and enhances the mobile friendliness of your store.
Here are some practical steps you can use for Lazy loading and mobile speed optimization:
- To speed up your initial load and to delay loading off-screen images, use (loading=”lazy”) on your product images.
The code to use for this is:
liquid
CopyEdit
<img src=”{{ image | image_url }}” loading=”lazy” alt=”Product title”>
- Use a thumbnail image to defer the video so that it only loads when clicked.
- Use Shopify’s (image_url: width) filter for serving smaller images on smaller screens.
- You can also set a specific image height in the CSS to prevent layout shifts while browsing. The code to do this is:
css
CopyEdit
img {
min-height: 300px;
}
- If you are a developer, we recommend using the Intersection Observer for loading the animations, images, or videos only when they come into view, which is faster than using the scroll-based triggers.
Shopify Speed Optimization Apps 2026
There are several Shopify speed optimization apps available to help improve your site’s speed. Brief detail for each suggested app is given below.
Plug in SEO
This app helps to identify broken links, issues with your images, and also provides you with performance-related tips.

Advanced Tips
If you are a developer who is working on a Shopify store, or even if you are someone who is using the assistance of a developer to optimize your store’s speed, then consider these advanced tips to help your store optimize for speed.
- Remove all the unused schemas.
- Inline critical CSS for above-the-fold content.
- Even though Shopify uses Fastly CDN, we still recommend layering it up with a Content Delivery Network like Cloudflare for extra security.
- Use browser caching for static assets.
- For Shopify Plus users, we recommend using Shopify’s API features to delay non-critical scripts.
