This type of site would including listing/s of products available, including descriptions and pricing. Furthermore, it would allow the visitor to select one or several items, complete delivery information and process payment details.
It should be noted that naturally this type of site would require a database and would be written in a scripting language.
Often it is very difficult to have the exact same page layout for a shopping cart than for the normal website. One solution is to host the shopping cart separately (with a different host name) as many companies have done. This makes it apparent to the visitor that they on a different site, but the the site does belong to you. For example:
- Main website hostname: www.yourdomain.com
- Shopping cart hostname: shop.yourdomain.com
Additionally, depending on the form/s of payment you wish to accept, the shopping cart (especially the payment section) should be encrypted.
