A domain extension (also called a TLD or top-level domain) is the part of a domain name that comes after the dot, like .com, .net, or .org. Extensions tell visitors something about your website: .com is the universal default, .org signals a nonprofit, and newer options like .ai, .io, or .store indicate your industry. There are over 800 extensions to choose from, ranging from generic TLDs like .com to country-code TLDs like .ca or .de.
