How to Speed Up a Shopify Store: 10 Practical Fixes
Written by Nethma DissanayakeOnline Store Builder4 min read
Ten practical ways to speed up a Shopify store: fewer apps, lighter images, a simpler theme, fewer scripts and smarter product pages, with a simple way to measure each change.
If you want to speed up a Shopify store, you do not need to be a developer to make a real difference. Most slow stores are slow for the same few reasons: too many apps, oversized images, a heavy theme and scripts that nobody remembers adding. Speed matters because shoppers leave pages that feel slow, and many of your visitors are on a phone with an ordinary mobile connection. These ten fixes are listed roughly in order of effort, so you can start with the easy wins.
Measure first, so you know what helped
Before you change anything, test your store so you can compare afterwards. Open your home page, one collection page and one product page in PageSpeed Insights and note the mobile scores and the main warnings. Write the numbers down. Then change one thing at a time and test again. Scores move around a little between tests, so look for clear changes rather than a single point.
Also test on a real phone. Open your store on mobile data, not only on fast home Wi-Fi, and tap through to checkout. What you feel as a customer matters more than any score.
1. Remove apps you do not use
Every app can add code to your storefront, even after you stop using it. Go through your installed apps and remove anything you no longer need. Uninstalling an app does not always remove its leftover code from your theme, so check the theme files or ask your developer to clean up. This is often the single biggest improvement on older stores.
2. Compress and resize your images
Large product photos are the most common cause of slow pages. A photo straight from a phone or camera can be many times larger than it needs to be.
- Resize images to the size they are actually shown, not larger.
- Compress them before upload with a free tool such as Squoosh.
- Use modern formats such as WebP where possible. Shopify serves modern formats automatically for images it hosts, so uploading a reasonable size is usually enough.
- Keep a consistent aspect ratio so the page does not jump around while loading.
3. Choose a lighter theme
Some themes load far more code than they need, with sliders, animations and features you will never use. If your theme feels heavy, try a lighter one and compare the scores. Shopify's own free themes are designed to be fast and are a good baseline. A simple theme with a good photo often sells better than a busy one.
4. Limit sliders, videos and animations
Auto-playing videos, big sliders and long animations look impressive but slow the first screen. Keep the top of your home page simple: one strong image, a clear message and one button. If you use video, load it only when the visitor chooses to play it.
5. Reduce third-party scripts
Chat widgets, tracking pixels, review badges, pop-ups and social feeds each load code from another company. They add up quickly. List every script on your store, decide which ones earn their place, and remove the rest. For the ones you keep, make sure they load after the main content rather than blocking it.
6. Keep collection and product pages focused
Pages with dozens of products, many filters and large galleries load more data. On collection pages, show fewer products per page and use pagination or a simple "load more" button. On product pages, keep the gallery to the best five to eight images and place the buy button and price near the top.
7. Watch your fonts
Custom fonts are files the browser must download. Use no more than two font families and a small number of weights. System fonts are fastest. If you use a custom font, make sure text is visible while it loads so visitors do not stare at a blank space.
8. Fix layout shifts
If buttons and text jump while a page loads, visitors tap the wrong thing and get frustrated. This is often caused by images without set dimensions, banners that appear late, or pop-ups. Give images fixed sizes, avoid inserting banners above content, and delay pop-ups until the visitor has had time to read.
9. Clean up your theme code
Over time, themes collect leftover snippets from old apps and experiments. A developer can audit your theme, remove unused code and remove duplicate scripts. If you edit your theme yourself, always duplicate it first so you can go back.
10. Make checkout smooth
Speed is not only about pages loading. A checkout with fewer fields, clear delivery options and visible payment choices feels faster because people finish sooner. Offer the payment methods your customers actually use, and make error messages clear. In Sri Lanka this often means a local card gateway and cash on delivery, so check that those choices are easy to find.
A simple routine to keep your store fast
- Test your home, collection and product pages each month.
- Before installing an app, ask whether you really need it and what it adds to the page.
- Compress every image before you upload it.
- Review your apps and scripts every few months.
- Test on your own phone after any big change.
Final thoughts
To speed up a Shopify store, start with what visitors feel: fewer apps, lighter images and a simple first screen. Measure before and after so you keep the changes that work.
