Shopify Store Speed Optimisation: Practical Fixes

Slow stores lose sales, especially on mobile data. Most Shopify speed problems come from apps and images, which are fixable.

Audit and remove unused apps

Each app can add scripts and styles to every page. Uninstall apps you no longer use and check theme files for leftover code, which often remains after uninstalling.

Optimise images

Upload images at sensible dimensions rather than huge originals, and use Shopify's image sizing features. Lazy-load images below the fold so the first screen appears quickly.

Choose a lean theme

Modern Online Store 2.0 themes tend to be faster and more flexible than heavily customised older themes. Test theme demos on mobile before choosing.

Limit third-party scripts

Chat widgets, review apps, heatmaps and multiple tracking pixels each add weight. Keep only what you use, and load non-essential scripts after the page becomes interactive.

Test product and collection pages

Home pages are often fastest; product and collection pages carry more weight. Test them on mobile with PageSpeed Insights and real devices.
