@usaleem9876 ,

Hope you are doing well. 

Welcome to the Shopify Community.


I have gone through your store. It really looks nice. You have choosen the best-known e-commerce solution Shopify platform currently on the market.


Optimizing your Shopify store is time-consuming. Themes are made up of Liquid, HTML, CSS, and JavaScript code. When you edit or customize the themes, file sizes can increase and affect your store speed.


Google PageSpeed Insights is a free tool to help you find and fix issues slowing down your web application. Get your PageSpeed score and use PageSpeed suggestions to make your web site faster through our online tool.


I have checked your site in the page insight chrome tool. your website score is very low.

  • You should remove the unused app code. It will be beneficial to your store. and makes your theme code easier to read.
  • 3rd party apps & codes which take time to load and their size . They decrease the speed.
  • Some code can be removed or reordered to improve your online store's performance. If you're not using an app, then you can remove it.
  • If you're removing an app, then consider removing code that was added as part of the app install process. Some apps help you with this process by wrapping their code in {% comment %} tags that mention the app name.
  • Removing unused app code is a best practice that avoids running code for unused features, and makes your theme code easier to read.

You can refer this article :


One of the most common recommendations I found is “Defer offscreen images”. This is an indication that all of the site’s image assets are loading at once.

So you can use lazy load for these images.


  • To defer loading of offscreen images in your Shopify site, you will have to modify your Theme (theme.liquid file) to leverage the lazySizes library. Here's how:
  • Download the lazysizes Javascript library from here and upload it to your theme's /assets folder. 



  • Note(once check ‘lazysizes Javascript library’ in assets repo. has available or not)


  • Add the following lines to your theme.liquid just before the </head> tag:

<script src="{{ 'lazysizes.min.js' | asset_url }}" async="async"></script>

  • Change the image tags in your theme by adding class "lazyload" to the image tags and changing the src attribute to data-src attribute. 
  • te:

{% for img in product.images %}

 {% assign img_url = img | img_url: '1x1' | replace: '_1x1.', '_{width}x.' %}

 <img class="lazyload" 

 src="{{ img | img_url: '300x' }}"

 data-src="{{ img_url }}"

 data-widths="[720, 1080]"

 data-aspectratio="{{ img.aspect_ratio }}"


{% endfor %}


We’ve had the best success for our clients by working with our developers to implement the lazysizes, because it's quite complicated for non technical people.

You need to work on following points :

  • Theme Upgrade if there is a scope and upgraded theme available
  • Reduce JS Payload.
  • Use Critical CSS .
  • Replace GIFs With Static Images
  • Reduce Large Image Sizes
  • Migrate Tracking Codes To Google Tag Manager
  • Compress Images
  • Limit Third Party JavaScript & Shopify Apps
  • Preload Web Fonts. 
  • I would suggest limiting to one and using a standard web font.

By fixing these issues, your website speed score can definitely improve.

If you’re looking to improve your Shopify store’s site performance or SEO.

Hello @usaleem9876,


By following the below steps, you can significantly speed up your Shopify store:

1. You can run the Shopify Theme Inspector for Chrome to identify the lines of code that are slowing down pages in your online store.
2. Image compression is important and a necessity for faster loading web pages. Make sure your images are of good quality and do not add too many images on a single page. You can try some tools like
3. Removing unused app code is a best practice that avoids running code for unused features and makes your theme code easier to read.
4. Using a theme that is optimized for performance means a theme that is responsive, fast, and takes minimal time to load the page.
If you choose a theme with numerous sliders, fancy animations, advanced navigation systems, etc., will affect your page speed. If your theme is loading slow, consider disabling the theme features you don't need.
5. Themes contain CSS, JS, and HTML which can increase and affect your store speed. So disable theme features you don't use.
6. Loading extra data your customers aren't using can impact your store speed without adding value.
7. Using slideshow, which are high-quality images combined with transitions, take time to load when the user clicks the link to the homepage. So instead you can use a single high-quality hero image.
8. Use a System font which is a font that is already installed on most computers. For example Segoe UI, Times New Roman. If you use a font that does not yet exist on your customer's computer, then the font has to be downloaded before your text can be displayed. This impacts the time that your store takes to load.
9. Replace GIFs with static images
10. To reduce the initial load time, you can use Lazyload technique
11. Remove third-party JS scripts and Shopify App which you are no longer using
You should disable app features you don't use, or you can remove the app if you don't need it. If you are removing an app make sure to remove code that was added as part of the app install process.
12. Minimize HTTP requests. For example: Combine & inline your CSS scripts
13. Avoid unnecessary redirects and fix broken links
14. Use minified CSS and JS files
15. Don't add too many images on a page
Adding too many images on a page can be frustrating. It can significantly slow the load time of your website. Also, it can overwhelm visitors, which will ultimately result in a poor user experience, a high bounce rate, and a high probability of lower rankings in relative search results.
16. You can use Google PageSpeed Insights to view more detailed metrics for pages in your store.

If your website takes longer than 3 seconds to load, 40% of your traffic will be lost. Apart from speeding up your store, for getting better conversions, make sure your store products are Found on Google. When your customers search on Google, your product can be found only if your page is indexed. Note that once a URL gets indexed, customers will start finding your store through organic searches, you will start getting order conversions for virtually zero cost.
