When you want to go to a website, you type something like http://www.companyname.com into your web browser. But have you ever thought about what the “com” at the end means. It is called a Top Level Domain (TLD). It is part of the addressing used to make it easier to remember the name of a website. “com” is short for “commercial”. You have probably seen other ones like “.net” and “.edu” for education. There are also country ones like “.uk” and “.ca” for Canada.
Recently, the rules were changed and a lot of new top level domain names were created. This is great news if you are trying to get a domain name that closely matches your business name. You might look for your business name using “.biz” or “.shop”. You can even get industry specific with “.plumbing” or “.lawyer”. So, if your companyname.com is already taken, you might try a different companyname.tld.
