Domain: A web address. Also known as a URL (Uniform Resource Locator)
Domain parking/domain monetisation: domain owners can use domain parking to lease out online real estate to advertisers by using a service “instant website” landing page. These pages contain highly targeted advertising and the domain owner earns a commission from the advertiser for every visitor conversion. This is a form of PPC (pay-per-click) advertising.
Domain Investor: a domain owner who invests in generic, dictionary-term URLs and builds up a domain portfolio to resell or “park”, with the purpose of achieving a return on investment (ROI). Think of it as a property investor building a portfolio of real estate and securing a return with a combination of resale and leasing. Domain investors are NOT cybersquatters. Domain investors channel funds into acquiring generic names that depend on type-in traffic. Also known as a “domainer”.
Cybersquatter: A cybersquatter is someone who registers a name with bad faith intent to profit from the goodwill of a trademark belonging to someone else. They “squat” on the name, often with the aim of selling to the rights holder at an inflated price. This word is sometimes mistakenly and incorrectly applied to domain investors.
Domaining: the business of acquiring and monetising Internet domain names for their use as an advertising medium. Also known as domain investing.
PPC: ‘Pay Per Click’ – a way to monetise traffic. Refers to the “per click” commission that domain parking clients earn for using a parking page on their domain name.

Participants in the secondary market include the marketplaces, the domain investors (domain owners) and potential buyers, made up of domain investment professionals, branding agencies, companies looking for a domain for a new ad campaign and new businesses seeking the ideal name for their online presence.
Domain primary market: domain names that have not previously been owned by anyone else, and are available to register at a registrar (eg. goDaddy).
Registrar: (eg. www.godaddy.com) the company that has a direct relationship with the domain name registries and is authorised to sell domain names to Registrants. This distribution platform for available-to-register domains is known as the primary domain market.

TLD: top level domain – the last part of a domain name, such as .com, .net and .org
