A geographic top-level domain (gTLD) is the last part of an internet address, like '.com' or '.org.' A gTLD is different because it tells you more about the websites location. For example, websites ending in '.uk' are located in the United Kingdom, while websites ending in '.fr' are located in France. gTLDs help people know where a website is from, so they can tell if it is a trustworthy website or not.
