Shopify is a fully-hosted, subscription-based e-commerce platform that enables businesses to create and manage online stores without handling technical infrastructure.
As one of the leading SaaS e-commerce solutions, Shopify serves over 4 million merchants worldwide with an all-in-one platform including hosting, security, payments, and store management. The platform offers various pricing tiers and uses a templated approach with customizable themes and apps from its extensive marketplace. Shopify handles all technical maintenance, updates, and security, allowing merchants to focus on selling.
Shopify's closed ecosystem and theme-based architecture create specific constraints for A/B testing. Client-side tools such as Mida run on storefront pages you control through theme.liquid (product pages, collections, cart drawer, and other theme templates). Shopify deprecated checkout.liquid and no longer allows arbitrary scripts on native checkout URLs ( /checkouts/... ) on any plan. To change the Information, Shipping, or Payment steps, merchants must use Checkout UI Extensions; Shopify restricts those extension targets to Shopify Plus stores. Standard plans can still customize Thank you and Order status pages with approved checkout apps and basic checkout branding (logo, colors, fonts).
A merchant runs Mida client-side experiments on product pages and a cart drawer via theme.liquid . They cannot run the same script-based test on Shopify's native checkout Information step. To A/B test checkout UI there, they would need Shopify Plus, a custom Checkout UI Extension, and Mida's server-side SDK ( mida-node ) for variant assignment and goal tracking—not a Plus upgrade alone.
Use Shopify when deciding which experiment metric matters most. Tie it to the customer journey stage being tested, then compare the result with revenue, purchase rate, and any downstream behavior that could offset the initial lift.
A common mistake is judging Shopify with only one surface-level metric. Ecommerce tests should also consider purchase quality, revenue per visitor, average order value, and whether the lift holds across devices and traffic sources.
