1. find a physical store (find a server/virtual host)

you may rent or do it by yourself or but it

Rent-means you need “virtual host” (search engine can help you)
Do it by yourself - find a computer and set it as a server

here is the server-related search

2. put your commodities in your physical store (uploading your contents to server)

Web contents are placed to the server(photos or texts)

visitors can link to your website with your domain name easily
by setting DNS server
