To speed up your Shopify store and pass Core Web Vitals, pick a lightweight theme, simplify your homepage, remove unused apps, minify your code, reduce DNS lookups, compress your images and videos, and manage scripts with Google Tag Manager. These steps lower load times, improve user experience, and can lift your conversion rate.

A slow Shopify store costs you sales. According to Portent’s research, an e-commerce site that loads in one second converts at about 3.05%—but that figure drops to just 0.67% at four seconds. That’s a huge gap, and it grows wider every second your pages take to load.

The good news? You don’t need to be a developer to fix this. This guide walks you through seven practical tips to speed up your Shopify website and improve your Core Web Vitals. You’ll learn which tools to use, what changes make the biggest difference, and how to measure your progress along the way.

What Are Core Web Vitals?

Core Web Vitals are a set of metrics Google uses to measure the real-world experience of your website. They focus on three things: how fast your content loads, how quickly your site responds to clicks, and how stable your page looks as it loads.

There are three Core Web Vitals you need to know:

Metric What it measures Good score
LCP (Largest Contentful Paint) How long the main content takes to load Under 2.5 seconds
INP (Interaction to Next Paint) How fast the page responds when a user clicks or taps Under 200 milliseconds
CLS (Cumulative Layout Shift) How much the page jumps around while loading Under 0.1

INP replaced First Input Delay (FID) as an official Core Web Vital in March 2024. As Shopify’s own performance team notes, INP better reflects the responsiveness and interactivity users actually experience.

You can check your scores for free using Google PageSpeed Insights or GTmetrix. Both tools show your current Core Web Vitals, flag specific problems, and suggest fixes. Run a test before you start so you have a baseline to measure against.

Tip 1: Choose the Right Theme

Your theme is the foundation of your store’s speed. A bloated theme packed with animations, sliders, and unused features will slow you down before you’ve added a single product.

How to Pick a Fast Shopify Theme

Look for themes built with performance in mind. Shopify’s free themes, like Dawn, are designed to be lightweight and fast. If you want a paid option, marketplaces like ThemeForest offer plenty of choices—but check the demo’s speed score before you buy.

Here’s how to test a theme before committing:

  1. Find the theme’s live demo page.
  1. Run that URL through Google PageSpeed Insights or GTmetrix.
  1. Compare the LCP and overall score against other themes.

If you’d rather build a custom look, tools like Themes Generator and iThemes Builder let you create your own design. Whichever route you choose, keep it simple. A clean, focused theme almost always beats a feature-heavy one on speed.

Tip 2: Simplify Your Homepage and Landing Pages

Your homepage is often the first thing visitors see, and it’s frequently the heaviest page on the site. Every extra section, image, and video adds load time.

How to Keep Your Pages Simple

Shopify’s own help documentation warns against adding too many sections to your page templates. High numbers of sections directly lower web performance.

To trim down your pages:

  • Cut unnecessary sections. Ask whether each block actually helps a shopper decide to buy. If not, remove it.
  • Limit autoplay videos. They’re data-heavy and can hurt your LCP score.
  • Reduce the number of products shown on large collection pages, or use pagination instead of loading hundreds of items at once.
  • Prioritize above-the-fold content. Make sure the first thing visitors see loads quickly, even if content lower down takes a moment.

A focused homepage doesn’t just load faster—it also guides shoppers toward what matters, which can improve conversions too.

Tip 3: Review and Remove Unused Apps

Shopify apps are easy to install and just as easy to forget. Each one can add code to your store, and that code keeps running even if you no longer use the app.

How to Streamline Your Shopify Apps

Many apps leave behind scripts and snippets even after you uninstall them. Over time, this clutter slows your store down.

Follow this process to clean things up:

Step Action
1 List every app currently installed on your store
2 Identify which apps you actively use and which you don’t
3 Uninstall the apps you no longer need
4 Check your theme code for leftover snippets from removed apps
5 Look for one app that can replace several (for example, a single marketing suite)

After removing apps, run a fresh speed test to confirm the improvement. You’ll often see a noticeable drop in load time after clearing out the clutter.

Tip 4: Minify Your Website Code

Minifying means stripping out unnecessary characters from your code—spaces, line breaks, and comments—without changing how it works. Smaller files download faster, which speeds up your store.

How to Minify Your Code

Your store relies on three main types of code: HTML, CSS, and JavaScript. Minifying all three reduces file size and improves load time.

You can use free tools to do this:

  • Minifier and similar online tools clean up CSS and JavaScript quickly.
  • Google Closure Compiler makes JavaScript download and run faster by compressing and optimizing it.

If you’re comfortable editing your theme files, back them up first, then replace your existing code with the minified versions. If you’re not confident doing this yourself, a Shopify developer can handle it in a short session. Either way, minification is one of the easiest wins for a faster store.

Tip 5: Reduce DNS Lookups

Every time your store loads content from an outside source—a font, a script, a tracking pixel—your visitor’s browser has to perform a DNS lookup. Each lookup adds a small delay, and they add up fast.

How to Cut Down DNS Requests

Fewer external requests mean fewer lookups and faster loads. Here’s how to reduce them:

  • Host fonts locally instead of pulling them from a third-party server.
  • Limit third-party scripts to only the essentials, like your analytics and payment tools.
  • Combine resources where you can, so your store makes fewer separate requests.
  • Audit your external connections using GTmetrix or Ahrefs, both of which can flag where your store reaches out to other domains.

Reducing redirects helps too. Each redirect creates another round trip, so clean up any unnecessary ones in your store’s settings.

Tip 6: Optimize Images and Videos

Images and videos are usually the largest files on any page, which makes them the biggest opportunity for speed gains. A single uncompressed hero image can hold up your entire page load.

Best Practices for Image and Video Optimization

Element What to do Tools to use
Images Resize to the actual display size, then compress Adobe Photoshop, Canva
File format Use modern formats like WebP for smaller sizes Shopify converts many automatically
Lazy loading Load images only as users scroll to them Built into most modern themes
Videos Compress before uploading and avoid autoplay Camtasia

A few extra tips:

  • Name your image files with descriptive, keyword-rich names. This helps SEO without affecting speed.
  • Add alt text to every image for accessibility and search visibility.
  • Host videos externally on a platform like YouTube or Vimeo rather than uploading them directly, which keeps the file weight off your store.

Optimizing your hero image alone can meaningfully improve your LCP score, since it’s often the largest element on the page.

Tip 7: Use Google Tag Manager

If your store runs multiple tracking scripts—analytics, ad pixels, heatmaps—each one slows your site as it loads. Google Tag Manager solves this by managing all your scripts from one place.

How to Use Google Tag Manager Effectively

Google Tag Manager is a free tool that lets you add, edit, and remove tracking tags without touching your theme code. Instead of pasting each script directly into your store, you load a single container that controls them all.

This approach helps your speed in three ways:

  1. Fewer scripts load directly in your store’s code.
  1. You can set tags to fire later, so they don’t block your main content from loading.
  1. It’s easier to remove old tags you no longer need, preventing the script clutter that slows stores down.

Set up your tags to fire only when needed—for example, a checkout tracking tag that loads only on the checkout page. This keeps unnecessary scripts off pages where they aren’t used, protecting both your load time and your INP score.

FAQs: Shopify Page Speed Optimization

How fast should a Shopify store load?

Aim for a load time under two to three seconds. Research from Portent shows conversion rates drop sharply after the first second, so the faster, the better. For Core Web Vitals specifically, target an LCP under 2.5 seconds.

Does Shopify speed affect Google rankings?

Yes. Google uses Core Web Vitals as a ranking signal, so a slow store can rank lower in search results. Faster pages give you a better chance of appearing higher and attracting organic traffic.

What’s the easiest way to speed up my Shopify store?

The quickest win for most merchants is removing unused apps and optimizing images. Both require no coding, take little time, and often produce an immediate improvement in load speed.

What tools can I use to test my Shopify speed?

Google PageSpeed Insights and GTmetrix are the two most popular free options. Both show your Core Web Vitals scores and point out specific problems to fix. Ahrefs can also help you audit external requests and technical SEO issues.

Do Shopify apps slow down my store?

They can. Each app may add code that runs on your pages, and some leave scripts behind even after you uninstall them. Review your apps regularly and remove any you no longer use.

Is INP more important than LCP?

Both matter, but they measure different things. LCP measures load speed, while INP measures responsiveness after a user interacts with your page. INP became an official Core Web Vital in March 2024, so you should track both for a healthy store.

Key Takeaways

Speeding up your Shopify store is one of the highest-return projects you can take on. Faster pages convert better, rank higher, and create a smoother experience for every shopper.

Here’s a quick recap of the seven tips:

Tip Main benefit
Choose a fast theme Sets a lightweight foundation
Simplify your pages Reduces load on key pages
Remove unused apps Cuts script clutter
Minify your code Shrinks file sizes
Reduce DNS lookups Fewer external delays
Optimize media Trims your heaviest files
Use Google Tag Manager Controls tracking scripts

Start by running a free test on Google PageSpeed Insights or GTmetrix to find your current scores. Then tackle the easiest fixes first—removing unused apps and compressing images—before moving on to code-level changes. Small, steady improvements add up to a noticeably faster store and a better bottom line.
