gTLDs: Generic Top Level Domains

Generic TLDs are divided into three sets: unrestricted, sponsored and geographic. Unrestricted gTLDs can be registered by anyone who wants one. The core group consists of .com, .info, .net and .org. Sponsored gTLDs have been underwritten by an organization or private agency; .aero is an example for the air-transport industry. Geographic gTLDS are not common, only .cat and .asia exist today, but they are to be used in connection with a geographical, ethnic or cultural group.

List of gTLDs

The domains are marked as restricted or unrestricted. Registricted domain registers must meet certain conditions to receive such a domain; unrestricted is okay for anyone. For example, If you have clients that fall into hospitality or museum industries, you can help them obtain a restricted domain.

Most major companies register a .com domain. But is it really necessary for your website? Well, a ccTLD does just fine if your target audience is in a specific country, otherwise it is advisable trying to find a .com domain. .com’s are also the most easy to understand for users and therefore good for branding purposes.

Pros of gTLDs:

* Suitable for an international market.

* There is a familiarity with .com which you will not find with any other extension.

Cons of gTLDs:

* Can be difficult to find a good and available gTLD.

* Will not rank as high as ccTLD’s when it come to regional searches. In Sweden, .se domains are more valued and trusted than a generic TLD.
