TLD stands for Top Level Domain and it is the last part of the domain name. In other words, it is the part of the domain name located to the right of the dot (" . "). It identifies some additional information associated with the website such as location (.de; .fr; .uk); industry (.auto; .physio; .florist) or its purpose (.com; .org; .info). The ones that identify a country are called Country-code Top Level Domains (ccTLD) and the most common are Generic Top Level Domains (gTLD).
