Domain parking is an advertising practice used primarily by domain name registrars and internet advertising publishers to monetize type-in traffic visiting an under-developed domain name. The domain name will usually resolve to a page containing relevant advertising listings and links. These links will be targeted to the predicted interests of the visitor and may change dynamically based on the results that visitors click on. Usually the domain owner is paid based on how many links have been visited (e.g. pay per click) and on how beneficial those visits have been. The keywords for any given domain name provide clues as to the intent of the visitor before arriving. For example, the domain fast-weight-loss.com might point to a page of links to diets and weight-loss drugs.

Domain parking can be classified as monetised and non-monetised. In the former, ads are shown to visitors and the domain is 'monetised'. In the latter, an "Under Construction" or a "Coming Soon" message is put up on the domain. This a single page web site that people see when they type your domain name in a web browser. This is one quick way for getting an Internet presence. You can temporarily park your domain names before your web site is ready for launching.
