Your business name should also have a domain name. The most difficult thing when it comes to register a domain name for your business is the choosing the right domain extension. There are over 1600 options and it is confusing what should you go with. One easy idea is to choose a domain extension that matches your business name. Certain extensions are better suited to certain types of businesses. For example, if you're a law firm, a ".law" domain might be a good choice, or if you're a TV company, a ".tv" domain could work well.
