What is a domain name and how do I choose a good one?
Updated on 3 November 2026
Your domain name is your identity on the Internet. Your visitors can reach your site by typing your domain name in the address bar of their web browser.
A domain name consists of a series of alphanumeric characters and an extension (also called a TLD, for "Top Level Domain").
Here are a few examples of domain names:
- votresiteweb.com
- ma-compagnie.net
- mesloisirs123.net
You are free to choose the domain name that suits you best, provided it has not already been registered by someone else.
Here are a few pointers for choosing a good domain name:
- Choose a domain name that is preferably short and easy to remember (note, however, that most .com domain names of fewer than 6 characters have already been registered!)
- Use a domain name that reflects the content of your website.
- If it is a corporate site, use the company's name, if possible.
- Use keywords in your domain name to improve your presence in search engines.
As for the domain name's extension, you can choose between (partial list):
- .com: open to the general public, the most popular extension on the Internet.
- .net: open to the general public, initially used for computing companies. Nowadays this extension is used almost everywhere.
- .org: open to the general public, initially used for groups or organisations, but this extension is now used almost everywhere.
- .biz: open to the general public, used mostly by businesses.
- .ca: stricter registration criteria and somewhat higher costs; this extension is generally reserved for Canadians or Canadian businesses.
- .info: open to the general public, generally used for informational sites.
- .me: a new extension available since 2008, for personal sites.
- .mobi: sites aimed at users of mobile devices
- .eu: reserved for those residing or having a registered office in Europe.
- .fr: extension reserved for French residents or businesses.
Note that buying a domain name gives you no legal right, and that it may be wise to register a trademark to protect your domain and limit potential trouble, especially if the name in question matters to you.
A domain name registration is valid for a minimum period of one year. After your domain expires, it is no longer reachable through the Internet and, after a period of 60 to 180 days, could become available again for registration by other people. We suggest renewing your domains well in advance so as not to lose them!
