Top Quick Shopify Speed Optimization Checklist

Here come 8 proven ways through which the loading time and speed of a Shopify store can improve. These methods can help store owners to retain customers and attract new buyers by having a Shopify site with fast-loading speed.


Shopify Speed Optimization


1. Optimize Images and Videos

A large volume of unoptimized images and videos is frequently the most popular reason for website slowness. There are 4 solutions that you might want to consider as follow:

1.1. Compress and Merge Images

Compressing large images is one of the most efficient ways to speed up Shopify site. In particular, TinyJPG or TinyPNG are good options for you to compress the size of images without decreasing quality with lossless compression.

Or else, when uploading many different images, which demands loads of the server’s image requests, you can choose image consolidation. It helps to merge many distinguished icons and thumbnails into one, called “CSS Sprites” or “CSS Image Sprites”. You will subsequently well perform your Shopify speed optimization.


1.2 Employ Lazy Load Images

eCommerce websites are packed with numerous pages. When customers click on the website’s link, the browser needs to get in action and download all the available content on the pages to get ready to browse the web pages. Hence, loading all the content takes a fairly irritating time.

With Lazy-loading, the problem is skillfully solved. It functions based on the principle of demand and supply. The browser will only load the content that visitors first see, in other words, above-the-fold content. The content below the fold will not be shown unless the customer scrolls down.

As the browser does not need to load the whole website content at once, it helps to solve your question of how to speed up Shopify website.

1.3 Apply Deferred Video Loading

Videos are similar to images in this regard. Deferred Video Loading is technical  performance that helps your site to load faster by deferring the loading of video resources until they are required.

We have a Shopify speed test using this technique. This saved 4MB of page weight and contributed to the page loading .65 seconds faster.

2. Choose Proper Fonts

One of the most notable factors that you cannot exclude to conduct Shopify speed optimization is proper fonts. Shopify’s font library contains a collection of fonts such as system fonts, Google fonts, and licensed fonts from Monotype. All of these fonts are freely available to use on all Shopify online shops.

Be noticed that if you use fonts that do not exist on your customer’s computer, it would be irritating that your customer needs to download new fonts to have the text displayed.

In order to steer clear of downloading new fonts to your customer’s computer, you might want to think about using system fonts. A system font is known as a font that already existed on most computers. There are a bunch of options you can choose such as mono, serif, or sans-serif families. Among these families, you can also use any of the font styles from which, like bold, and italic.

3. Remove Unnecessary Shopify Apps

It cannot be denied that Apps are handy, useful, especially if you are not tech-savvy and have no prior experience with coding.


Shopify Speed Optimization

You may add more functionality to your Shopify website by installing apps that meet your needs. An eCommerce store owner, for example, can download a live chat app rather than create one from scratch.

However, be aware that these apps add load to your website, even if you are not using them. These apps have a lot of JS and CSS files that run in the background and negatively impact your Shopify speed optimization.

Therefore, it’s important to frequently review all of the apps that you are using. Then, there are two simple steps you can follow:

  • Disable app features you no longer use or remove the ones that do not apply to your store. Make allowance for online store features and speed optimization.
  • If you are deleting an app, think about removing any code that was added during the installation procedure. Some apps assist you in this procedure by enclosing their code in {% comment %} tags that include the app name.

Deleting unneeded app code prevents running code for features that aren’t used and makes your theme code easier to comprehend.

5. Harness AMP

Another solution for Shopify speed optimization is Mobile Accelerated Pages, or AMP, a standard framework that permits merchants to develop mobile-friendly web pages loading speedily.

Smartphones have evolved from a luxury product to a necessity in today’s fast-paced world. In this era of digital technology, people no longer use cellphones solely for communication, they take online classes, transfer payments, surf websites, go online shopping, and such.

Take a gander at the statistics (updated by Statista) below to see how important it is to improve the user experience for mobile visitors:

Thanks to this framework, customers will be able to visit your website much more quickly. Many apps such as 4-star ratings FireAMP or RocketAMP are available on the Shopify App store to assist you in creating AMP pages. Or else, you can consider building the Shopify API to develop these AMP pages.

6. Organize All Tracking Codes with Google Tag Manager

Data collecting from your site is necessary to get more insight into your clients’ behavior, but it can lead your website to slow down.

When you measure conversions, goals, and retargeting independently, all of those tracking tags add to the number of requests on your page, which might hurt its overall speed at the end. They can also prevent the page’s content from rendering if they aren’t done asynchronously.

You may condense all of your tracking tags into one JavaScript request using a management solution like Google Tag Manager. They allow you to handle various store tags with only one snippet of code. Check out this guide for further information on how to use Google Tag Manager with your Shopify store.

  • Prominently shows all broken links in the app’s dashboard. Additionally, you can receive reports by mails.
  • Easily generate 301 URL redirects. All you have to do is set up a redirect pattern, and the software will take care of the rest.

Broken links harm SEO. When a user lands on a page that isn’t available, he pushes the back button on his browser. This increases the bounce rate of the website.
