Start With a Domain Name
Pick out the name for your webpage and register it. It sounds simple and it is, but it will cost you what usually amounts to a small annual fee to own the rights to the name. Search the Internet and you will quickly find lots of companies that you can register your domain name with. Unfortunately, a lot of people and businesses have registered domain names, so there's a chance your chosen name could already be taken. Be flexible and creative, but make sure the name reflects the webpage or website you are building.
