Let’s not sugar-coat it, if your Shopify store is slow, it’s costing you sales. In today’s competitive eCommerce landscape, shoppers expect seamless experiences and lightning-fast load times. Blink, and they’ve bounced.
Shopify page speed isn’t just a “nice to have”, it’s a core driver of trust, conversion, and revenue. If your website speed isn’t up to scratch, all the clever marketing campaigns in the world won’t save you from a rising bounce rate and a shrinking basket size.
If you're focused on improving your store’s conversion rate, start by tackling page speed not just cosmetic changes.
How Slow Load Times Hurt Your Shopify Store
A slow-loading website doesn’t just frustrate users it actively drives them away. According to Google, even a one-second delay in mobile page load can slash conversions by up to 20%. That’s a fifth of your potential revenue, gone.
The harsh truth? The problem is usually self-inflicted. Merchants often overload their stores with unnecessary apps, oversized images, and bloated themes all in the name of “enhancing user experience.” But ironically, it has the opposite effect.
The impact of slow load times on Shopify conversion rates is significant and often overlooked. It’s time to start thinking of performance as a direct growth lever.
What’s a Good Page Load Time for Shopify?
A slow eCommerce site can damage your sales figures. Here’s your benchmark: aim for under 2 seconds. Anything slower, and you're losing customers especially on mobile.
For UK shoppers used to instant gratification and fast broadband speeds, expectations are high. The faster your Shopify store loads, the more likely they are to browse, add to cart, and convert.
To learn how to make those seconds count, explore our guide on CRO best practices that directly influence performance and user experience.
Top Reasons Shopify Stores Load Slowly
Let’s break it down. These are the usual suspects when it comes to poor Shopify performance:
- Unoptimised image : High resolution photos that haven’t been compressed or lazy-loaded
- App overload : Redundant plugins creating bloated code and third-party requests
- Bulky themes : Overbuilt templates packed with features no one uses
- No CDN : Not using a Content Delivery Network to serve assets faster globally
- JavaScript bloat : Excessive animations and tracking scripts
These technical issues don’t just hurt UX, they kill conversions. For a deeper look at the role of performance in CRO, see our full guide on how to optimise your Shopify store for more conversions.
Proven Ways to Reduce Page Load Time on Shopify
How to reduce page load time on Shopify?
To reduce page load time on Shopify, compress and optimise all images, remove unnecessary apps, use a fast-loading theme, minify JavaScript files, and enable lazy loading. These steps improve performance and boost conversions, especially for mobile users. Regularly audit your store with tools like Google PageSpeed Insights and GTmetrix to identify and fix slow-loading elements.
Here’s what works in optimising your store’s performance:
- Compress and optimise images: Tools like TinyPNG or Shopify’s built-in compression go a long way.
→ Use image optimisation Shopify best practices on every page. - Audit your apps: Remove any app that isn’t directly contributing to sales or customer experience.
→ Many store owners are surprised by the negative impact Shopify apps have on load speed. - Use lightweight, fast themes: The theme is your store’s foundation. Choose one known for speed or better yet, build a bespoke one.
→ Prioritise theme performance from day one. - Minify and defer scripts: Combine JavaScript files and load them after critical content.
→ This alone can dramatically reduce page load time. - Enable lazy loading: Don’t load images until they’re needed. It’s low-effort, high-reward.

Speed Improvements That Drove Conversions
One of our clients, a UK-based DTC brand, came to WIRO with a beautifully designed but painfully slow Shopify store. Page loads were averaging 5.2 seconds, and conversion rates were stuck at 1.4%.
After a complete performance overhaul including a custom lightweight theme, a full app audit, and aggressive image optimisation we brought load time down to 1.7 seconds. Conversions jumped to 2.6%, and revenue per session increased by 38%.
This is exactly what happens when you apply CRO best practices that prioritise performance over unnecessary features.
How Page Speed Impacts Conversion Rates: The Data
- 1s delay = 20% fewer conversions
- 53% of mobile visitors abandon a site that takes more than 3 seconds to load
