gTLDs (Generic Top Level Domain) are generic first level domains. A TLD is a suffix at the end of a web address (for example .io in Youdot.io). The gTLD sub-category is reserved for generic and general use as opposed to ccTLD which are associated with a country or territory.
Some common gTLDs:
- .com
- .biz
- .gov
- .info
- .net
- .org
