A good eCommerce website

Keep the design of the website as clutter-free as possible. Give users a clear idea of where they are within your website structure with features like breadcrumb navigation and drop down menus. Also make sure to add elements such as a consistently visible shopping cart through a user's time on your website so that users know exactly what they have in their cart and how much it costs.

The website must be straight and to the point, do not deviate users with too many categories, focus on a small niche. Have good looking quality pictures preferably that include people using the products.
