You open your online store on your phone. You wait, and the screen stays white. You wait more. Then finally, your products pop up.
If you feel frustrated, imagine how your buyers might feel.
When your online shop takes too long to load, people leave. They do not wait around, and they leave the site and buy from your competitor instead, leading to a loss of sales.
Many store owners ask us, why is my Shopify speed score so low? You might run a Shopify page speed test and see a scary red score. You wonder why your Shopify website is loading slowly.
The good news is that you are not stuck. This guide explains the exact reasons your Shopify store speed drops. Furthermore, we will also look at how to speed up a Shopify site so you can increase page speed and make more money.
Quick Answer: What Slows Down Your Shopify Store?
Your Shopify store speed score usually drops because of too many apps, large uncompressed images, heavy third-party scripts, and complex themes with too many features. Cleaning up your code and optimizing your media files are the fastest ways to fix a Shopify site loading slowly.
Why Speed Matters for Your Shopify Store
Think about buying a pair of shoes at a local market. If the shop owner takes ten minutes to show you the box, you walk away.
Online shopping is the same. When a Shopify page speed score is bad, your conversion rate drops. Since people hate waiting.
Google considers Core Web Vitals as part of its page experience signals. These metrics measure loading performance, responsiveness and visual stability. However, good Core Web Vitals scores do not guarantee higher Google rankings. Page speed is one part of SEO, while content quality, relevance and other ranking factors also matter.

Getting professional help from Shopify store speed optimization services can save you time, but you can also fix many things yourself. Let us look at the top ten reasons your score is low.
10 Common Reasons Your Shopify Speed Score Is Low
1. Too Many Apps Installed
Apps add cool features to your store. They add pop-ups, currency converters, trust badges, and review widgets.
Every app adds extra code to your theme. When your browser loads your page, it has to load code from ten different app developers. This makes your shopify website loading slow.
How To Fix The Issue?
Go through your installed apps. Delete any app you do not use. If an app does not make you money or help your customers, remove it.
2. Unoptimized Images and Banners
Large banners and images might slow down your Shopify website. Good quality images will show all the details of the product to the buyer, but if the image is big and too much media is loaded, this will take some time to load, especially on a mobile device or through the internet that does not have a fast connection. The Shopify platform automatically optimizes images, but selecting the proper image size and avoiding large media will still help you improve the performance of the page.
For instance, if a clothing shop uses banners to advertise a new collection of dresses, they may use too large banners that will slow down the loading of the web page.
The Fix: Use clear images with dimensions suitable for your theme and the devices your customers use. Shopify automatically optimizes storefront images, but very large images, heavy banners and poorly loaded media can still affect page speed. Where appropriate, use modern image formats such as WebP and ensure banners display well on mobile screens.
3. Heavy, Feature-Packed Themes
Many theme developers include themes with too many animations, video backgrounds, pop-ups and other slider options. Though they may appear fancy, they affect your Shopify store speed score.
How To Fix The Issue?
Install a minimalistic theme with no animation or carousel, as far as possible. A simple layout would load faster, even on mobile phones.
4. Too Many Third-Party Scripts
Third-party scripts are small pieces of code provided by apps and external tools used on your Shopify website. They help facilitate functionalities such as live chats, customer reviews, visitor tracking and marketing pop-ups. However, every additional piece of code takes additional time and effort to load. Having many tools installed on your site will slow down the opening of your web page and force visitors to wait before seeing your offers.
For instance, a skincare website can use different apps for customer reviews, WhatsApp chat, visitor tracking, discount pop-ups, etc. Every app will add additional bits of code and slow down the process of opening a web page.
The Solution: Review all the tools used on your site and remove unused ones. Retain those apps and scripts only that are useful either for your clients or your business. Then conduct tests to find out whether there were any improvements.
5. Large Video Files
Videos can show how a product works. They can also take up a lot of data.
A furniture store may use a video banner to show a sofa in a living room. If the video starts loading as soon as the page opens, it may delay other important content.
How to fix it:
- Use short videos only when they add value.
- Compress video files.
- Avoid autoplay when it is not needed.
- Use a poster image before the video loads.
- Load videos only when visitors need them.
A good product photo may be enough for many products.
6. Too Many Web Fonts
Typography gives your brand personality, but loading too many custom fonts slows down how quickly your words appear on the screen. If you use five different font styles, your store forces the browser to download five separate font files from external servers before showing a single word to your visitor.
How To Fix It?
Use only one or two font families, at most, in your whole online store. When using system fonts that you know work reliably, or when using different weights of the same font, use only two weights instead of all the weights that the font offers. Rather than using light, regular, semi-bold, bold, and black variants of your font, use regular and bold instead. This way, you will significantly reduce file sizes and make your web pages load noticeably faster on mobile devices.
7. Render-Blocking JavaScript and CSS
The browser reads your source code from top to bottom. JavaScript and CSS code files will stop rendering the page until they are downloaded fully.
The Fix: There are several minor steps you can take to make your Shopify store load faster. First, you should minify your CSS and JS files in order to make them smaller. Next, you need to delete any CSS code that is not necessary for your theme anymore. You can delay scripts that are not needed right away. This allows important content, such as product images, text and buttons, to load sooner.
8. Poor Mobile Optimization
Most of your buyers shop using smartphones on 4G or 5G mobile networks. If your store was only tested on a fast office broadband connection, you might miss how heavy it feels on a mobile phone.
How to Solve The Issue?
Test your store using a mobile device on a standard mobile connection. Keep your page layout simple, reduce heavy elements and ensure buttons are easy to tap.
9. Outdated Liquid Codes
Shopify uses a template language called Liquid. Over time, as you edit your theme, add apps, and delete things, old code gets left behind. This leftover code is called code bloat.
The Fix: Clean up your theme code. If you have deactivated an application six months ago, confirm whether the snippets of that application’s code are still in your theme.liquid file.
10. External Media and Third-Party Loading Delays
Shopify provides a built-in content delivery network (CDN) for storefront assets, so most store owners do not need to configure a separate CDN. However, external media files and third-party services can still affect loading speed if they respond slowly or add unnecessary requests to your store.
How to Fix?
Use Shopify’s built-in tools to load images faster. Check videos, fonts, and other media hosted on outside sites. Remove any that are not needed or that slow down your store.
