A domain hack is a creative and clever strategy used in the selection of domain names. A domain hack is not about hacking or any illicit activities; instead, it refers to a domain name that combines the domain name with the top-level domain (TLD) to form a word or phrase.A popular example of a domain hack is the social media platform “del.icio.us”. Here, the term “delicious” is formed by combining the domain name “del” with the subdomain “icio” and the top-level domain “.us”. This creative use of the domain and TLD makes the entire URL spell out a common word, which is the essence of a domain hack.Domain hacks can be highly desirable because they’re memorable, catchy, and often shorter than typical domains. They can also provide unique branding opportunities, particularly for startups or tech companies who want to project an innovative image.
