Customers expect instant access to information, smooth navigation, and seamless shopping experiences. That’s why it’s crucial to ensure that your Shopify store is optimized for optimal page speed.

In this comprehensive guide, we will take a look at the steps to optimize page speed on Shopify and explore best practices that will help you deliver a superior user experience. 

So, let’s dive in and unlock the secrets to achieving lightning-fast page speed on your Shopify store!

How to optimize page speed on Shopify

Here are some tried-and-tested methods that will help you enhance your site’s performance, deliver a seamless user experience, and boost customer satisfaction. 

Follow the 8 simple steps given below to optimize the page speed on your Shopify store:

Step 1: Choose a lightweight Shopify theme

Start by selecting a lightweight Shopify theme from the Shopify Theme Store. Opt for themes that are designed for performance, as some themes may come with unnecessary elements that can slow down your site. 

We have identified some top-performing themes that you can use:

Step 2: Reduce large image sizes

Resizing large image assets is crucial for speeding up your Shopify site. If you tend to use an excessive number of images, it can lead to heavy page weight and slower downloads. 

Unoptimized images, uploaded at larger sizes than necessary, worsen performance and waste user resources. Use Chrome DevTools to identify larger images and optimize them for faster rendering.

Step 3: Compress images

Compressing images is crucial for optimizing Shopify site speed. It reduces file sizes, allowing faster loading of website content. Use Shopify apps like or tools like Optimizilla for automatic or manual image compression.

Step 4: Replace GIFs with static images

While GIFs can enhance user experience, they tend to be large in file size. Consider replacing GIFs with static images wherever possible to reduce page weight.

Step 5: Lazy load images

Lazy loading images is a recommended technique for improving Shopify site speed. By deferring offscreen images, you can prevent all image assets from loading at once, which is common in image-heavy sites. 

Lazy loading allows images to load only as users scroll down the page, resulting in faster website performance. Shopify provides helpful documentation on implementing lazy loading, and using libraries like lazy sizes has been effective in our experience.

Step 6: Limit third-party JavaScript & Shopify apps

Carefully review and minimize the use of third-party JavaScript and Shopify apps on your site. Each additional app or script adds to the number of requests your site makes, potentially slowing it down. 

Consider removing any unnecessary apps or codes and evaluate the impact of each one. Focus on the essential features and functionalities and ensure they are worth the performance trade-off.

Step 7: Migrate tracking codes to Google tag manager

Consider migrating your tracking codes to Google Tag Manager. This tool allows you to manage all your tracking codes in one place without touching the site’s code directly. Google Tag Manager loads the code asynchronously, preventing it from blocking the rendering of your site’s content. 

Step 8: Run your store through Google PageSpeed insights

You can try Google PageSpeed Insights to check your site’s performance. Enter the URL of your page into the tool, and it will provide metrics and recommendations to improve speed. 

Focus on key data points like “First Contentful Paint” (FCP) and “Time To Interactive” (TTI) to understand how quickly your content starts loading and when the page becomes interactive for users. Regularly test your site to measure the impact of your speed optimization efforts.

By following these detailed steps, you’ll be able to optimize the page speed of your Shopify site.
