6 tips to boost your Shopify speed and performance

The pace at which your online store loads can make or break the customer experience. In the bustling world of e-commerce, having a snappy website is as essential as the quality of the products you sell. Some common signs your Shopify store might need to improve are pages that take longer than three seconds to load, images that appear sluggish, low conversion rates, or frequent cart abandonments.

Speeding up your Shopify store elevates the user experience and bolsters your site’s search engine rankings. This often leads to better visibility and higher conversion rates—meaning more sales!

You’re about to embark on a journey through the essentials of enhancing your Shopify site’s speed. From analytical tools to practical tweaks and strategic overhauls, we’ve got you covered.

1. Analysing your current Shopify performance

Tools and metrics for measuring speed

Get started with tools like Google PageSpeed Insights and Shopify's speed report. These tools are fantastic because they give you a snapshot of your site’s performance and highlight areas for improvement.

Identifying problem areas

These reports aren't just numbers and graphs; they tell a story of what’s working and dragging you down. Look for common culprits like unoptimised images or hefty code.

Setting performance benchmarks

Once you know your current performance metrics, set clear, achievable goals. It’s also wise to peek at your competitor’s sites to see how you stack up against them.

2. Image optimisation techniques

Opt for a single Hero Image instead of sliders

From a design perspective, sliders with multiple rotating images make sense and look attractive. But did you know sliders slow down your site and often go unnoticed? A single high-quality hero image with a clear Call-to-action (CTA) captures user attention and boosts site speed more effectively.

Proper image formats and compression

Did you know JPEGs can be ideal for photographs while PNGs are better for graphics with fewer than 16 colours? Tools like TinyPNG or Adobe's compression tools help maintain quality while drastically reducing file size.

Lazy loading implementation

Lazy loading is a technique that loads images only when they enter the browser’s viewport. This method means that page load times significantly drop as only a portion of images load initially.

Effective use of image sizes and responsive images

Different devices deserve different treatments. With responsive design, you can ensure pictures look crisp and load efficiently across all devices by altering their size based on the viewer's screen.

3. Minimizing code bloat

Streamlining HTML, CSS, and JavaScript

Utilise tools like CSSNano and UglifyJS to minify your code without losing functionality. Consider inlining critical CSS and deferring JavaScript, significantly reducing load time.

Avoiding excessive Shopify apps

Installing numerous apps for added functionality is tempting, but each extra app can slow down your page. Carefully evaluate each app's impact and retain only those that offer essential benefits.

Custom code considerations

Sometimes, customised solutions are necessary, but they must be meticulously managed and updated to avoid redundancies or conflicts that slow down the site.

4. Shopify hosting and CDN (content delivery network)

Shopify is a hosted platform, so it manages the details of maintaining your online store and its complexities (CDNs, DNS, etc.). You won’t have control over Shopify web hosting. Fortunately, Shopify hosting is among the fastest in the world. Shopify servers are connected to a content delivery network (CDN), which means that when customers visit your store, they'll download content from the nearest CDN node, ensuring fast and reliable access.

5. Themes

Fast and lightweight theme

You either build a theme from scratch or choose one from the Shopify theme library and pick the one optimised for performance. There are some essential factors to consider: (1) A Shopify 2.0 theme architecture, (2) less clean code, and (3) no reliance on external libraries, especially the outdated jQuery Javascript library.

Avoid excessing modifications

To maintain the theme’s performance, focus on essential UX elements and minimise unnecessary customisations. Excessive modifications can lead to a bloated, slow-loading website.

Mobile Optimisation Strategies

With more than half of internet traffic coming from mobile devices, testing your site’s performance on mobile devices is crucial. Implementing Accelerated Mobile Pages (AMP) can significantly improve mobile loading speed. Several Shopify apps can assist in creating AMP pages.

6. Advanced Techniques and Considerations

Address unnecessary HTTP requests, URL redirects and broken links

Fixing broken links is straightforward and can improve SEO and user experience. However, resolving excessive HTTP requests and broken redirects requires editing the main Shopify store code. If you're unfamiliar with Liquid and JavaScript code, it's best to seek assistance from Shopify developers specialising in speed optimisation.

Third-party integrations and their impacts

Carefully select and control third-party integrations, ensuring they don't compromise your site’s performance.


If you're looking to improve the speed of your Shopify store, consider implementing the steps mentioned above. From image compression to reducing the number of apps and enabling lazy loading, these adjustments can significantly improve your site's loading time.

Whenever you make significant changes to your store, such as adding new apps or making design modifications, it's essential to test your site's speed to ensure that these changes haven't negatively impacted performance. It's a good idea to perform speed tests more frequently before and during peak shopping seasons, such as holidays or sales events, as increased traffic can affect your store's performance.
