A weblet, is a separately made website that is connected to, or associated with, a larger site but has a different URL and is made to promote a product or service. Some common names for a weblet are minisite and microsite. Often weblets are used to add specific information that is connected to a TV, print, or web advertisement. What’s great about weblets is that they can be individually optimized to increase organic search rankings since it is specific in nature.
However, not all weblets are solely made to promote items such as clothes, shoes, electronics, etc. some are editorial in nature. Others are community sites created to bring together people that share common interest. For instance the WWE organization may have a fan site set up for one of their wrestlers. A web community allows for better segmenting and targeting from a corporate standpoint.
