There is no restriction on how you design your website, except to quickly add that it must at least have pages for the following basic menu items:
• Homepage / Home
• About Us
• Products / Services
• Terms of Service
• If your business is regulated, you are mandated to have an additional page, with details of your regulation.
• If your website is an ecommerce website, your links for login and register / registration must work together with your fully working online store.
