Shopify is an ecommerce platform used to create, manage, and sell through online stores.
It matters because development decisions affect speed, security, scalability, tracking, SEO, and maintenance. A site that looks good but is fragile or hard to update can quietly hold back every marketing channel.
Example
A retailer uses Shopify to manage products, variants, inventory, and checkout. Before launch, it checks a real product’s shipping options, taxes, and payment flow rather than reviewing only the storefront’s home page.
