A microsite is an individual web page or a small cluster of pages which are meant to function as a discrete entity (such as an iFrame) within an existing website or to complement an offline activity. The microsite's main landing page can have its own domain name or subdomain. Usage Microsites are typically used in web design to add a specialized group of information, either editorial or commercial. Such sites may be linked in to a main site or not or taken completely off a site's server when the site is used for a temporary purpose. The main distinction of a microsite versus its parent site is its purpose and specific cohesiveness as compared to the microsite's broader overall parent website. Microsites used for editorial purposes maybe a page or group of pages that, for example, might contain information about a holiday, an event or similar item which gives more detailed information than a site's general content area may provide. A community organization may have its main site with all the organization's basic information but creates a separate, temporary microsite to inform about a particular activity, event, or similar. Often, microsites will be used for editorial purposes by a commercial business to add editorial value. For example, a retailer of party goods may create a microsite with editorial content about the history of Halloween or some other holiday or event. The commercial purpose of such editorial microsites, (beyond driving product sales), may include adding value to the site's visitors for branding purposes as well as providing editorial content and keywords allowing for greater chances of search engine inclusion. Normally, microsites do not contain web applications. Microsites may be used for purely commercial purposes to create in-depth information about a particular product, service or as editorial support towards a specific product, such as describing a new technology. A car manufacturer, for example, may present a new hybrid vehicle and support the sales presentation with a microsite specific to explaining hybrid technology. In a large corporation, the various business units may own their specific content in a microsite within the corporations main website. With the prevalence of keyword contextual advertising, (more commonly referred to as pay per click or PPC), microsites may be created specifically to carry such contextual advertising. Or along a similar tactic, they're created in order to specifically carry topic-specific, keyword-rich content with the goal of having search engines
