There are several platforms suitable to start an e-commerce business: Magento and WordPress/WooCommerce are open-source, and Shopify - SaaS or software as a service. They all are great for e-commerce. And choosing among them, you need to set priorities. I bet on uniqueness, functionality, and design. Magento is a complex system, it allows customizing the website according to your requirements, whether it is design or functionality. Implement whatever you want and it will look unique and modern.
Shopify here is limited: it allows making little changes to design, website structure - you have no access to the core, code, only to the front-end.
WooCommerce is somewhere between Shopify and Magento in case of customizations and integrations. Analyzing all platforms, I choose Magento 2. Why?
It has got responsive design. With user-friendly mobile themes, a responsive layout, and a mobile-friendly checkout, your e-commerce website has a better opportunity to successfully lead users to make a purchase.
Let's don't forget about the faster checkout process. Out of the box, Magento 2 proposes a two-step checkout: on the first tab, customers fill in the shipping information; on the second one – they simply review it and fill in the payment information. This way is fast and convenient. Another satisfying feature for your customers is the display of the checkout totals right after finishing the first step, which reduces the risk of unfinished purchases.
Magento provides advanced SEO. In addition to its basic, out-of-the-box SEO options, Magento can also be integrated with more complex, custom SEO strategy to make a bigger impact. By creating unique meta content and friendly URLs, and making good use of canonical tags and redirects, Magento leads your e-сommerce website to great results.
