What Is a Shopify Speed Score?

So, you’ve heard the buzz about the Shopify speed score and are probably wondering what all the fuss is about. Well, strap in because you’re about to find out!

The Shopify speed score is like your online store’s pulse rate — it measures how swiftly your pages load for visitors. Why does this matter? Because in the world of click-and-mortar, speed is king!

This score isn’t just a random number; it plays a crucial role in your Shopify experience. A higher speed score means a smoother ride for your customers, making browsing, cart loading, and checking out as fast as a cheetah!

And the faster your site, the happier your customers and the better your sales. Now, who wouldn’t want that? Stay tuned as we shift gears and teach you how to put the pedal to the metal to speed up your Shopify website!

How Does Shopify Speed Score Work?

The Shopify Speed Score is a tool designed to help Shopify store owners understand how quickly their site loads for visitors. Various factors influence this score and are integral to managing an e-commerce site’s performance. Here’s a breakdown of how it works.

Calculation of Shopify Speed Score

Shopify’s Speed Score is calculated using Google’s Lighthouse performance scoring system. This system considers a range of metrics that gauge how a site performs under different conditions. The primary metrics used include:

  • First Contentful Paint (FCP): This measures the time it takes for the first piece of content to appear on the screen after a visitor navigates to your site. It’s an early indicator of how fast your site starts to load for a user.
  • Speed Index: This shows how quickly the contents of a page are visibly populated. It’s an overall indicator of how quickly a page appears to load.
  • Largest Contentful Paint (LCP): This measures the time it takes for the largest content element visible in the viewport to become fully visible. For many sites, this could be a large image or block of text.
  • Time to Interactive: This measures the time it takes for a page to become fully interactive, meaning how quickly a user can click on something and receive a response.
  • Total Blocking Time (TBT): This quantifies the time a page is blocked from responding to user input, such as mouse clicks or keyboard presses.
  • Cumulative Layout Shift (CLS): This measures the stability of a site as it loads. If elements shift around a lot as the site loads, the CLS will be high, frustrating users.

Shopify’s Use of Lighthouse Scores

Shopify uses a modified version of Lighthouse tailored specifically for e-commerce websites. Its algorithm focuses particularly on the aspects that most affect shopping experiences.

The speed score is presented as a number out of 100, where higher scores represent better performance. Shopify also compares your score against other stores to show you where you stand.

The Impact of a Low-Speed Score on Your Store

Do you need speed? Your Shopify store certainly does! Let’s discuss why zipping up your Shopify page speed optimization isn’t just good practice — it’s crucial for your shop’s street cred and cash flow!

User Experience

Picture this: a customer who visits your store is excited to browse, but your pages are loading like molasses. They’ll bounce faster than a ping-pong ball in a championship match.

A snappy site keeps users happy and engaged, easily gliding from product to product, increasing the chances of sticking around and shopping.

SEO Implications

Search engines are like the cool kids at school—they prefer hanging out with the fastest in the crowd. Google loves speed and rewards faster sites with better visibility in search results.

If your site is slow, it might as well be invisible. Shopify page speed optimization isn’t just a luxury; it’s your ticket to the SEO fast lane.

Conversion Rates and Sales

Slow load times are the ultimate deal-breakers in e-commerce. Even a few seconds delay can cause a significant drop in conversion rates. Think of it as a race: the faster your pages load, the quicker visitors can hit that ‘buy’ button.

This is where a Shopify speed optimization service comes into play. It transforms your sluggish site into a speed demon, boosts sales, and keeps those cash registers ringing.

Common Causes of Slow Speed Scores on Shopify

Ever feel like your Shopify store is moving at a snail’s pace? If your Shopify speed score is more tortoise than hare, it might be time to consider a Shopify speed optimization service. Let’s uncover the culprits behind the slowdown and get your Shopify store back in the fast lane!

Heavy Themes and Unoptimized Images

Think of your Shopify theme as the outfit your website wears. Imagine it’s decked out in a heavy, ornate ball gown — stunning but not exactly sprint-friendly! Heavy themes loaded with complex graphics and oversized, unoptimized images can significantly weigh down your site.

These digital divas take longer to strut down the internet runway, which means longer loading times for your visitors. Opting for streamlined, optimized images can cut the fluff and keep your pages loading swiftly.

Excessive Apps and Plug-ins

Apps and plug-ins are the cool gadgets of the Shopify world. They add tons of functionality to your store, but hooking too many onto your site is like expecting someone to run a race with a backpack full of bricks.

Each plug-in and app can introduce additional scripts that need to load, and if these aren’t efficiently managed, they can slow your site down to a crawl. It’s about finding that sweet spot — enough apps to power your store’s needs without overloading it.

Poor Coding Practices

Now, onto the sneaky gremlins of the Shopify world — inefficient code! Sometimes, the code behind your Shopify site isn’t as clean or efficient as it could be. This includes bulky JavaScript, excessive CSS, and cluttered HTML.

Think of it as having a messy toolbox. If your tools are scattered everywhere, finding what you need will take longer and getting the job done. Cleaning up your code can help your pages load faster, giving your users a smoother ride and potentially boosting your Shopify speed score.

Top 6 Practical Steps to Improve Your Shopify Speed Score

Optimizing Images and Videos

Visuals are your site’s heartthrob, but they can lower your speed score if they’re not optimized. To keep things light and speedy, start by scaling down your images to the smallest size that maintains their visual appeal.

Compression is key, so use tools like Adobe Photoshop or free online services like TinyPNG to compress images without losing quality. Additionally, stick to formats that are made for the web, like JPEG for photos and PNG for graphics with fewer than 16 colors, and consider next-gen formats, such as WebP, for even better performance.

Theme Selection and Customization

Choosing the right theme is like picking the right type of shoes for a marathon — not all of them are made for speed. Start with themes optimized for speed by checking theme reviews and ratings for performance insights.

A complex theme might look fancy but can slow your site down, so customize it with a focus on simplicity and speed. Remember to keep your theme updated to ensure you have the latest speed enhancements and bug fixes.

Reducing Redirects and Script Load Times

Every extra second your page takes to load can hurt customer satisfaction, so keeping it lean is crucial. Minimize redirects, as each creates additional HTTP requests and can significantly increase load time.

Try to keep them below three. Also, combine and minify JavaScript files and defer the loading of JavaScript until it’s needed so users can start interacting with your site sooner.

Using Performance Analysis Tools

You can’t improve what you don’t measure. Some tools designed specifically for this purpose can improve your site’s efficiency and user experience. Here are some of the best tools.


GTmetrix extends beyond performance metrics, delivering in-depth analyses of your site’s speed and user experience. Upon evaluating your site, GTmetrix presents a detailed summary, including load times, page sizes, request counts, and an overall performance score.

It also provides a timeline view of your site’s loading process, pinpointing the exact elements contributing to slowdowns. With its actionable suggestions, GTmetrix aids in refining various aspects, from image optimization to script handling, helping to enhance your site’s functionality and efficiency.


Adding to this toolkit, CrazyLoad takes a unique approach by strategically sequencing the loading of third-party technologies and significant digital elements like high-resolution images.

This optimization not only boosts key performance metrics, such as up to a 40% increase in conversion rates and enhanced customer engagement indicated by increased average time on page and basket size, but also improves NPS metrics, enhancing customer satisfaction.

CrazyLoad immediately enhances your site’s performance metrics, as visible in GTMetrix and Google PageSpeed Insights, ensuring faster load times and improved SEO rankings.

Google PageSpeed Insights

Google PageSpeed Insights is a robust tool that evaluates your website’s performance across mobile and desktop devices. By inputting your URL, it examines your webpage’s content and assigns a score up to 100, reflecting your site’s speed and optimization status.

It offers practical tips for enhancing your site’s performance, including image compression and browser caching utilization. This tool is essential for quickly understanding your site’s current speed and identifying effective strategies to improve its overall performance.

Leverage Browser Caching

Think of browser caching as giving your customers a “speedy pass” for their next visit to your store. When someone visits your Shopify store, browser caching stores parts of your site on their device — like images, JavaScript files, and CSS — so that the next time they visit, their browser can load the page without having to fetch all of this data from the server again.

It’s like remembering the faces at a party; next time, no introductions are needed, just straight to the fun! Setting this up can dramatically reduce loading times, making your store faster for repeat visitors.

Dive into your Shopify settings or chat with your developer to get this feature moving. It’s a small tweak with potential for big speed gains!

Clean Up Your Apps

Let’s tidy up those unused apps! It’s easy to get app-happy, adding various tools and features that seem useful at the time. But just like a cluttered closet, a Shopify store bogged down with unused apps can slow your site’s performance.

Inventory your installed apps and remove any that aren’t pulling their weight. Think of it as decluttering for speed — each removed app simplifies the backend processes and lightens the load your site has to carry. This not only speeds up your site but also makes managing it simpler.

Plus, who doesn’t feel great after a good spring cleaning? Cutting out the excess gives your Shopify store that fresh, fast, and efficient feel!

Final Thoughts

Understanding how to speed up the Shopify website is crucial for ensuring your online store operates at peak efficiency. Speeding up the website influences customer satisfaction, SEO rankings, and overall sales.

You can markedly improve site performance by optimizing images, selecting efficient themes, and reducing script load times. Don’t let a slow website hinder your business growth.
