How do I set up A/B testing on Shopify?

You’ll need to install a compatible testing app or integrate a third-party A/B testing platform like Fibr. Most apps allow you to duplicate a product page or landing page and apply your variations, like different text, layouts, or buttons. Once variations are live, traffic is automatically split between them. These tools track performance and typically offer dashboards showing which version performs better based on your chosen goal (purchases, clicks, time on site). After enough data has accumulated, you can declare a winner and deploy that version storewide. Always preview changes on desktop and mobile before going live.
