In the eCommerce world—speed does matter!

Whether customers are browsing your website on desktop or mobile, they want a seamless experience throughout their buying journey.

Yes, gone are those 2G internet days when people would patiently wait on their mobile for a website to load. The internet speed has increased significantly over the past few years and so have your customers' expectations.

Considering these trends, Shopify speed optimization has become a critical component of the success for all store owners.

Why Should You Improve Shopify Page Speed?

Your Shopify store speed influences two essential aspects:

  • User Experience (UX): No one likes waiting these days. If a page takes too long to load, customers may lose patience and abandon the purchase, leave your website, or have negative emotions during the buying journey.

All these aspects can directly impact some crucial factors as follows:

    • Conversion rate
    • Bounce rate
    • Brand perception
  • Google Search Ranking (SEO): Google’s Core Web Vitals is a signal guideline that determines the factors that can affect website search rankings. Speed is one of them that can impact SEO and it can be verified using the Google PageSpeed Insights tool. But that’s not to say that you should be focusing only on page speed in your SEO efforts. Keep in mind that the relevance of your website content still plays a huge role in Google search rankings.

Unbounce did a survey with 750 consumers and found that nearly 70% of consumers say that site speed influences their willingness to buy from an online store.

In another interesting study with 188 marketers, Unbounce found that 85% of marketers' landing pages were slower as compared to Google's recommended speed of 5 seconds or less with a 3G connection.

How to Measure Shopify Page Speed?

When thinking of speed optimization for Shopify, the first thing that you need to check is the ongoing trend of your site’s speed.

It’s imperative to measure website speed not just for desktops but also for mobile users. Here’s an interesting finding from Skilled based on multiple studies:

64% of mobile users expect a website to finish loading within four seconds, whereas 47% of online shoppers expect a website to finish loading within just two seconds.

Now, there are different ways to check your Shopify store’s speed score. Let’s take you through a couple of important methods:

Check Your Store Speed through The Shopify Admin

You can view your store speed within Shopify Admin by following these steps:

1. Go to Shopify Admin and click on Online Store > Themes. Above the current theme section, you’ll be able to see your store’s Speed score for the last 7 days and how it is (good/slower) as compared to other similar stores on Shopify.

2. For a more detailed report, click on the tab above the current theme that displays the Speed score. You’ll be able to view the detailed report with:

  • Page type wise report
  • Speed score over time (in the last 7 days/30 days)
  • Day-wise score with events

Shopify's score is based on Google Lighthouse performance metrics, which are as follows:

  • 90 to 100: Good
  • 50 to 89: Needs Improvement
  • 0 to 49: Poor

Test Your Store Speed with PageSpeed Insights

Google’s PageSpeed Insights is one of the most popular tools to analyze the speed of your store. In 2018, Google announced that Pagespeed Insights would be powered by Lighthouse. So, you can get the Lighthouse analysis within the PageSpeed Insights tool.

How to use PageSpeed Insights:

1. Go to Google’s PageSpeed Insights tool
2. Enter the URL of your webpage
3. Click on the Analyze button

Now, let’s take the example of the same Shopify store which has a speed score of 31 as per Shopify’s Online store speed report.

11 Effective Ways to Improve Your Shopify Store Speed

Before we jump on to the different ways to optimize your Shopify store speed, it’s important to know that there are many factors that affect Shopify page speed, and not all of them could be under your control.

So, these factors are divided into two major categories:

Non-Controllable Factors:

  • Issues with your customer's device, network, or location
  • Shopify's infrastructure
  • Local browser cache and server-side cache
  • The assets inside the content_for_header Liquid object
  • Content delivery network (CDN)*
    • *Note: Although this is a non-controllable factor for most Shopify store owners, if you use GemPages, you can eliminate this problem. GemPages is partnered with UploadCare & AWS to speed up your content.

Controllable Factors:

  • Shopify Apps and their features
  • Themes and their features
  • Complex or inefficient Liquid code
  • Images and videos
  • Fonts

Now, let’s see how to improve Shopify store speed based on the controllable factors, using some of the best practices:

1. Remove Shopify Apps You Don’t Use

Shopify apps are essential. They help add features, enhance the style and improve your store performance.

But having too many apps can slow down your site speed. Especially customer-facing apps, which are used to display information on your web pages, can impact your store speed.

So, ask yourself a question - Do you really need all the apps that you installed?

And then, keep all the must-have Shopify apps. Re-evaluate the ones that just add bells and whistles, if any. And remove the ones that are not adding any value to your business but just adding some lines of code to your website.

2. Install A Fast Loading, Responsive Theme for Your Shopify Store

Choosing the right theme for your Shopify store has to be one of the most critical and well-thought-out decisions. Why? Because your Shopify theme is one of the key factors influencing your site speed and you don’t change your theme every day.

Here are some of the things to consider while choosing your theme-

  • Balance between style and performance:

While speed is obviously an important factor, the fact is, you also need to consider the theme that matches the brand style and content requirements. Check out demo stores for style and reviews for speed and performance. Make sure your theme is fully responsive on all devices.

  • Try and test your theme:

Before you finalize your theme, you must test if it meets your expectations, especially when you’re buying a paid theme. The good thing about the Shopify theme store is you don’t need to buy the theme until you publish it.

And if you’re looking for a free theme, Shopify has recently launched many free themes with Online Store 2.0 capabilities. Dawn is one of the free themes that focus on speed and it was built to create a great experience on all browsers.

  • Install the latest and licensed version:

This may seem obvious but still, some new Shopify store owners make this mistake. If you’re hiring someone to create and design your store, make sure that they install the latest version of the theme and not an outdated or pirated copy of a premium theme.

  • Upgrade your theme:

Check the theme developer change log at regular intervals and upgrade your theme whenever there are any major updates are launched.

3. Optimize Images and Videos Before Uploading

Images and videos help you express your brand’s message and emotions.

While you would love to make your website and content look rich with images and videos, you also need to be mindful of how they can impact your store’s speed.

Image Optimization

Recommended image formats

For product and website images, our recommended format is WebP for most Shopify stores. WebP is a modern image format developed by Google to provide better compression for images that are used on the web.
WebP format helps to save about 26-34% in file size as compared to PNG and JPEG. Thus, making web browsing faster.
Other than that, JPG and PNG images are fine if you’re not able to use WebP images. For logos or icons, use SVG format if you can.

Use Image Format Converters:

If you do not have images in WebP format, you can use a WEBP Converter like CloudConvert.com to convert your PNG or JPG images into WEBP image files.

CloudConvert’s JPG to WebP Converter tool

Using JPG to WebP Converter, four JPG images with a total size of 830 KB were reduced to a total size of 327 KB.

Compress and Resize Images:

If you want to use JPG or PNG file formats but the image files that are too big in size, it can impact your page load speed. It’s highly recommended to compress or resize images whenever needed. To compress PNG images, you can use online tools like compresspng.com and compressjpeg.com for JPG images.

Video Optimization

First, let's see the basics. There are two ways to upload videos for your products in Shopify:
1. Upload a video file
2. Embed a YouTube or Vimeo video link

 Video embedded on Blog page

For uploading a video, here are the Shopify criteria:

  • Video length: Up to 10 minutes
  • Video size: Up to 1 GB
  • Video resolution: Up to 4K (4096 x 2160 px)
  • Video file type: .mp4 or .mov

However, we recommend embedding YouTube videos because it won't require meeting these criteria and it'll also help you optimize your store speed.

4. Use a System Font

Many of us would love using specific fonts. But keep in mind that you may have to compromise your page load speed when your favorite fonts are not that common.

When a customer is browning your website, and you’re using a font that’s not pre-installed in the customer’s device, the system will have to download the fonts to display the texts.

Technically, this would just take a fraction of a second but it still impacts the page load speed. So, if your Shopify store speed is your priority, consider using the system font only.

System fonts help enhance the page load speed as they’re available on most systems worldwide, and thus, it eliminates that little step of downloading the font. Below are the examples shared by Shopify as to which fonts could be displayed when you choose a system font family:

  • Mono: Menlo, Consolas, Monaco, Liberation Mono, or Lucida Console
  • Sans-serif: BlinkMacSystemFont, Segoe UI, Roboto, Ubuntu, or Helvetica Neue
  • Serif: Iowan Old Style, Apple Garamond, Baskerville, Times New Roman, Droid Serif, Times, or Source Serif Pro

5. Use a Hero Banner Instead of a Slideshow

At the top of a website homepage, usually, there are two types of sections:

1. A slideshow (a.k.a slider or carousel), that displays constantly changing images, either automatically or manually. OR

2. A Hero banner, which is a single static image.

As a Shopify store owner, you might have that tempting urge to add a slideshow with multiple images to cover everything that your business has to offer.

But is it a good idea to display a slideshow on your website?

Well, for your site speed and user experience, it could be a not-so-good idea. Since the slideshow uses multiple image files, it can increase the overall page load time and slow down your website.

YouSea’s hero banner image

YouSea uses a hero banner image instead of a slideshow, and it not only avoids distractions but also makes it easy for the home page to load.

Redirect is a technique to send website visitors to a different URL instead of the original one that the visitor entered or clicked on.

Redirects can be helpful in many scenarios such as when you need to move a page from one URL to another one, delete a page, move the website to a new domain, merge duplicate web pages, etcetera. Also, redirects can be helpful to connect high-ranking pages with newly created content.

The only issue is that redirects can impact your store’s speed. Similarly, if your website has too many broken links, it can become a barrier to optimizing your store speed. You must fix the broken links and reduce redirects to achieve your desired speed score.

7. Organize All Your Tracking Codes with Google Tag Manager

Google Tag Manager is a solution that lets you manage and deploy different snippets of code on your website. By doing this, it allows you to transfer tracking information from your website to Google Analytics.

Note: It is to be noted that Google Tag Manager is NOT available on all Shopify plans but only on the Shopify Plus plan. You can learn more about considerations for the usage of Google Tag Manager on Shopify.

8. Consider Using Lazy Loading

Lazy loading is a technique to enhance your site's speed by slowly loading images or media files when a customer scrolls down a page. This ensures that any non-critical resources are not immediately loaded but only when they’re actually needed on the web page.

When you're using lazy-loading content, the browser would require fewer resources and it boosts the page load time. This can also provide a better user experience to your customers and help with SEO as well.

If you’re using the GemPages page builder, this feature is available out-of-the-box on all paid plans, starting from $29/month.

9. Make Your Page Lightning Fast with AMP

AMP stands for Accelerated Mobile Pages. It is an Open Source Project, originally created by Google, to optimize mobile web browsing and make it faster.

You can use AMP to speed up your Shopify site and there are two ways to do this:

1. Create AMP with custom coding

This method requires sound technical knowledge because it’s quite complex to create AMP through custom code. It requires adding alternate liquid templates and you can find more information here: How to Use Alternate Templates in Shopify Theme Development.

You can hire a Shopify Expert or freelance developer if you are not well-versed in these technical aspects.

2. Use a Shopify app for AMP

Now, let’s talk about the much easier option and that is using a Shopify app. There are multiple Shopify apps that can help you create AMP to improve your store speed and pass Core Web Vitals.

Shopify App Store with AMP apps

Shopify App Store has different apps to help you create AMP. Some of the apps that we recommend are AMP by Shop Sheriff, The AMP app, and Fire AMP.

10. Optimize CSS, JavaScript, and HTML

By seeing the technical terms like CSS, JavaScript, and HTML; you probably already have an idea that things are getting technical here.

Briefly talking, you can minify your store's CSS and JavaScript to optimize your Shopify store speed. Using online tools like CSS Compressor and JavaScript Minifier, you can compress your store's CSS and JavaScript.

However, this entire activity would require you to download the CSS and JavaScript files from your store and replace them with compressed files.

Unless you're a coder yourself, it's not advisable to experiment with these technical activities without taking the help of a Shopify Expert or a freelance developer.
